text: Production of hydrogen at large scale requires development of non-noble, inexpensive,
and high-performing catalysts for constructing water-splitting devices. Herein,
we report the synthesis of Zn-doped NiO heterostructure (ZnNiO) catalysts at room
temperature via a coprecipitation method followed by drying (at 80 °C, 6 h) and
calcination at an elevated temperature of 400 °C for 5 h under three distinct
conditions, namely, air, N2, and vacuum. The vacuum-synthesized catalyst demonstrates
a low overpotential of 88 mV at −10 mA cm–2 and a small Tafel slope of 73 mV dec–1
suggesting relatively higher charge transfer kinetics for hydrogen evolution reactions
(HER) compared with the specimens synthesized under N2 or O2 atmosphere. It also
demonstrates an oxygen evolution (OER) overpotential of 260 mV at 10 mA cm–2 with
a low Tafel slope of 63 mV dec–1. In a full-cell water-splitting device, the vacuum-synthesized
ZnNiO heterostructure demonstrates a cell voltage of 1.94 V at 50 mA cm–2 and
shows remarkable stability over 24 h at a high current density of 100 mA cm–2.
It is also demonstrated in this study that Zn-doping, surface, and interface engineering
in transition-metal oxides play a crucial role in efficient electrocatalytic water
splitting. Also, the results obtained from density functional theory (DFT + U
= 0–8 eV), where U is the on-site Coulomb repulsion parameter also known as Hubbard
U, based electronic structure calculations confirm that Zn doping constructively
modifies the electronic structure, in both the valence band and the conduction
band, and found to be suitable in tailoring the carrier’s effective masses of
electrons and holes. The decrease in electron’s effective masses together with
large differences between the effective masses of electrons and holes is noticed,
which is found to be mainly responsible for achieving the best water-splitting
performance from a 9% Zn-doped NiO sample prepared under vacuum.

text: As a key liquid organic hydrogen carrier, investigating the decomposition
of formic acid (HCOOH) on the Pd (1 1 1) transition metal surface is imperative
for harnessing hydrogen energy. Despite a multitude of studies, the major mechanisms
and key intermediates involved in the dehydrogenation process of formic acid remain
a great topic of debate due to ambiguous adsorbate interactions. In this research,
we develop an advanced microkinetic model based on first-principles calculations,
accounting for adsorbate–adsorbate interactions. Our study unveils a comprehensive
mechanism for the Pd (1 1 1) surface, highlighting the significance of coverage
effects in formic acid dehydrogenation. Our findings unequivocally demonstrate
that H coverage on the Pd (1 1 1) surface renders formic acid more susceptible
to decompose into H2 and CO2 through COOH intermediates. Consistent with experimental
results, the selectivity of H2 in the decomposition of formic acid on the Pd (1
1 1) surface approaches 100 %. Considering the influence of H coverage, our kinetic
analysis aligns perfectly with experimental values at a temperature of 373 K.

text: Thermoelectric materials convert heat into electricity, with a broad range
of applications near room temperature (RT). However, the library of RT high-performance
materials is limited. Traditional high-temperature synthetic methods constrain
the range of materials achievable, hindering the ability to surpass crystal structure
limitations and engineer defects. Here, a solution-based synthetic approach is
introduced, enabling RT synthesis of powders and exploration of densification
at lower temperatures to influence the material's microstructure. The approach
is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated
that the concentration of Ag interstitials, grain boundaries, and dislocations
are directly correlated to the sintering temperature, and achieve a figure of
merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and
resolve Ag2Se's challenges are provided, including stoichiometry issues leading
to irreproducible performances. This work highlights the potential of RT solution
synthesis in expanding the repertoire of high-performance thermoelectric materials
for practical applications.

text: The development of cost-effective, high-activity and stable bifunctional catalysts
for the oxygen reduction and evolution reactions (ORR/OER) is essential for zinc–air
batteries (ZABs) to reach the market. Such catalysts must contain multiple adsorption/reaction
sites to cope with the high demands of reversible oxygen electrodes. Herein, we
propose a high entropy alloy (HEA) based on relatively abundant elements as a
bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a
CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays
superior OER performance with an overpotential of 265 mV at a current density
of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard
commercial catalyst based on RuO2. This high performance is partially explained
by the presence of twinned defects, the incidence of large lattice distortions,
and the electronic synergy between the different components, being Cr key to decreasing
the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays
superior ORR performance with a half-potential of 0.78 V and an onset potential
of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the
OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking
advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi
HEA as air cathode and a zinc foil as the anode. The assembled cells provide an
open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a
peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that
stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8
mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2.

text: There is a need for the development of lead-free thermoelectric materials
for medium-/high-temperature applications. Here, we report a thiol-free tin telluride
(SnTe) precursor that can be thermally decomposed to produce SnTe crystals with
sizes ranging from tens to several hundreds of nanometers. We further engineer
SnTe–Cu2SnTe3 nanocomposites with a homogeneous phase distribution by decomposing
the liquid SnTe precursor containing a dispersion of Cu1.5Te colloidal nanoparticles.
The presence of Cu within the SnTe and the segregated semimetallic Cu2SnTe3 phase
effectively improves the electrical conductivity of SnTe while simultaneously
reducing the lattice thermal conductivity without compromising the Seebeck coefficient.
Overall, power factors up to 3.63 mW m–1 K–2 and thermoelectric figures of merit
up to 1.04 are obtained at 823 K, which represent a 167% enhancement compared
with pristine SnTe.

text: The direct, solid state, and reversible conversion between heat and electricity
using thermoelectric devices finds numerous potential uses, especially around
room temperature. However, the relatively high material processing cost limits
their real applications. Silver selenide (Ag2Se) is one of the very few n-type
thermoelectric (TE) materials for room-temperature applications. Herein, we report
a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se,
which can be extended to other metal chalcogenides. These materials reach TE figures
of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide
(Bi2S3) particles also prepared in an aqueous solution are incorporated into the
Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt %
of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering.
The presence of Bi2S3 significantly improves the Seebeck coefficient and power
factor while at the same time decreasing the thermal conductivity with no apparent
drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved
in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT
value (zTave) of 0.93 in the 300–390 K range is demonstrated.

text: AgSbSe2 is a promising thermoelectric (TE) p-type material for applications
in the middle-temperature range. AgSbSe2 is characterized by relatively low thermal
conductivities and high Seebeck coefficients, but its main limitation is moderate
electrical conductivity. Herein, we detail an efficient and scalable hot-injection
synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier
concentration and improve the electrical conductivity, these NCs are doped with
Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using
a reducing NaBH4 solution to displace the organic ligand and anneal the material
under a forming gas flow. The TE properties of the dense materials obtained from
the consolidation of the NCs using a hot pressing are then characterized. The
presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier
concentration and, consequently, the electrical conductivity. Opportunely, the
measured Seebeck coefficient varied within a small range upon Sn doping. The excellent
performance obtained when Sn2+ ions are prevented from oxidation is rationalized
by modeling the system. Calculated band structures disclosed that Sn doping induces
convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic
effective mass. The dramatically enhanced carrier transport leads to a maximized
power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon
scattering is significantly enhanced in the NC-based materials, yielding an ultralow
thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of
merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above
the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and
Te-free materials, which makes AgSb0.98Sn0.02Se2 an excellent p-type candidate
for medium-temperature TE applications.

text: 'High-performance semiconductors rely upon precise control of heat and charge
transport. This can be achieved by precisely engineering defects in polycrystalline
solids. There are multiple approaches to preparing such polycrystalline semiconductors,
and the transformation of solution-processed colloidal nanoparticles is appealing
because colloidal nanoparticles combine low cost with structural and compositional
tunability along with rich surface chemistry. However, the multiple processes
from nanoparticle synthesis to the final bulk nanocomposites are very complex.
They involve nanoparticle purification, post-synthetic modifications, and finally
consolidation (thermal treatments and densification). All these properties dictate
the final material’s composition and microstructure, ultimately affecting its
functional properties. This thesis explores the synthesis, surface chemistry and
consolidation of colloidal semiconductor nanoparticles into dense solids. In particular,
the transformations that take place during these processes, and their effect on
the material’s transport properties are evaluated. '

text: The power factor of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)
(PEDOT:PSS) film can be significantly improved by optimizing the oxidation level
of the film in oxidation and reduction processes. However, precise control over
the oxidation and reduction effects in PEDOT:PSS remains a challenge, which greatly
sacrifices both S and σ. Here, we propose a two-step post-treatment using a mixture
of ethylene glycol (EG) and Arginine (Arg) and sulfuric acid (H2SO4) in sequence
to engineer high-performance PEDOT:PSS thermoelectric films. The high-polarity
EG dopant removes the excess non-ionized PSS and induces benzenoid-to-quinoid
conformational change in the PEDOT:PSS films. In particular, basic amino acid
Arg tunes the oxidation level of PEDOT:PSS and prevents the films from over-oxidation
during H2SO4 post-treatment, leading to increased S. The following H2SO4 post-treatment
further induces highly orientated lamellar stacking microstructures to increase
σ, yielding a maximum power factor of 170.6 μW m−1 K−2 at 460 K. Moreover, a novel
trigonal-shape thermoelectric device is designed and assembled by the as-prepared
PEDOT:PSS films in order to harvest heat via a vertical temperature gradient.
An output power density of 33 μW cm−2 is generated at a temperature difference
of 40 K, showing the potential application for low-grade wearable electronic devices.

text: High carrier mobility is critical to improving thermoelectric performance
over a broad temperature range. However, traditional doping inevitably deteriorates
carrier mobility. Herein, we develop a strategy for fine tuning of defects to
improve carrier mobility. To begin, n-type PbTe is created by compensating for
the intrinsic Pb vacancy in bare PbTe. Excess Pb2+ reduces vacancy scattering,
resulting in a high carrier mobility of ∼3400 cm2 V–1 s–1. Then, excess Ag is
introduced to compensate for the remaining intrinsic Pb vacancies. We find that
excess Ag exhibits a dynamic doping process with increasing temperatures, increasing
both the carrier concentration and carrier mobility throughout a wide temperature
range; specifically, an ultrahigh carrier mobility ∼7300 cm2 V–1 s–1 is obtained
for Pb1.01Te + 0.002Ag at 300 K. Moreover, the dynamic doping-induced high carrier
concentration suppresses the bipolar thermal conductivity at high temperatures.
The final step is using iodine to optimize the carrier concentration to ∼1019
cm–3. Ultimately, a maximum ZT value of ∼1.5 and a large average ZTave value of
∼1.0 at 300–773 K are obtained for Pb1.01Te0.998I0.002 + 0.002Ag. These findings
demonstrate that fine tuning of defects with <0.5% impurities can remarkably enhance
carrier mobility and improve thermoelectric performance.

text: Cu2–xS and Cu2–xSe have recently been reported as promising thermoelectric
(TE) materials for medium-temperature applications. In contrast, Cu2–xTe, another
member of the copper chalcogenide family, typically exhibits low Seebeck coefficients
that limit its potential to achieve a superior thermoelectric figure of merit,
zT, particularly in the low-temperature range where this material could be effective.
To address this, we investigated the TE performance of Cu1.5–xTe–Cu2Se nanocomposites
by consolidating surface-engineered Cu1.5Te nanocrystals. This surface engineering
strategy allows for precise adjustment of Cu/Te ratios and results in a reversible
phase transition at around 600 K in Cu1.5–xTe–Cu2Se nanocomposites, as systematically
confirmed by in situ high-temperature X-ray diffraction combined with differential
scanning calorimetry analysis. The phase transition leads to a conversion from
metallic-like to semiconducting-like TE properties. Additionally, a layer of Cu2Se
generated around Cu1.5–xTe nanoparticles effectively inhibits Cu1.5–xTe grain
growth, minimizing thermal conductivity and decreasing hole concentration. These
properties indicate that copper telluride based compounds have a promising thermoelectric
potential, translated into a high dimensionless zT of 1.3 at 560 K.

text: The deployment of direct formate fuel cells (DFFCs) relies on the development
of active and stable catalysts for the formate oxidation reaction (FOR). Palladium,
providing effective full oxidation of formate to CO2, has been widely used as
FOR catalyst, but it suffers from low stability, moderate activity, and high cost.
Herein, we detail a colloidal synthesis route for the incorporation of P on Pd2Sn
nanoparticles. These nanoparticles are dispersed on carbon black and the obtained
composite is used as electrocatalytic material for the FOR. The Pd2Sn0.8P-based
electrodes present outstanding catalytic activities with record mass current densities
up to 10.0 A mgPd-1, well above those of Pd1.6Sn/C reference electrode. These
high current densities are further enhanced by increasing the temperature from
25 °C to 40 °C. The Pd2Sn0.8P electrode also allows for slowing down the rapid
current decay that generally happens during operation and can be rapidly re-activated
through potential cycling. The excellent catalytic performance obtained is rationalized
using density functional theory (DFT) calculations.

text: Physical catalysts often have multiple sites where reactions can take place.
One prominent example is single-atom alloys, where the reactive dopant atoms can
preferentially locate in the bulk or at different sites on the surface of the
nanoparticle. However, ab initio modeling of catalysts usually only considers
one site of the catalyst, neglecting the effects of multiple sites. Here, nanoparticles
of copper doped with single-atom rhodium or palladium are modeled for the dehydrogenation
of propane. Single-atom alloy nanoparticles are simulated at 400–600 K, using
machine learning potentials trained on density functional theory calculations,
and then the occupation of different single-atom active sites is identified using
a similarity kernel. Further, the turnover frequency for all possible sites is
calculated for propane dehydrogenation to propene through microkinetic modeling
using density functional theory calculations. The total turnover frequencies of
the whole nanoparticle are then described from both the population and the individual
turnover frequency of each site. Under operating conditions, rhodium as a dopant
is found to almost exclusively occupy (111) surface sites while palladium as a
dopant occupies a greater variety of facets. Undercoordinated dopant surface sites
are found to tend to be more reactive for propane dehydrogenation compared to
the (111) surface. It is found that considering the dynamics of the single-atom
alloy nanoparticle has a profound effect on the calculated catalytic activity
of single-atom alloys by several orders of magnitude.

text: As a bottleneck in the direct synthesis of hydrogen peroxide, the development
of an efficient palladium-based catalyst has garnered great attention. However,
elusive active centers and reaction mechanism issues inhibit further optimization
of its performance. In this work, advanced microkinetic modeling with the adsorbate–adsorbate
interaction and nanoparticle size effect based on first-principles calculations
is developed. A full mechanism uncovering the significance of adsorbate–adsorbate
interaction is determined on Pd nanoparticles. We demonstrate unambiguously that
Pd(100) with main coverage species of O2 and H is beneficial to H2O2 production,
being consistent with experimental operando observation, while H2O forms on Pd(111)
covered by O species and Pd(211) covered by O and OH species. Kinetic analyses
further enable quantitative estimation of the influence of temperature, pressure,
and particle size. Large-size Pd nanoparticles are found to achieve a high H2O2
reaction rate when the operating conditions are moderate temperature and higher
oxygen partial pressure. We reveal that specific facets of the Pd nanoparticles
are crucial factors for their selectivity and activity. Consistent with the experiment,
the production of H2O2 is discovered to be more favorable on Pd nanoparticles
containing Pd(100) facets. The ratio of H2/O2 induces substantial variations in
the coverage of intermediates of O2 and H on Pd(100), resulting in a change in
product selectivity.

text: In order to demonstrate the stability of newly proposed iridium-based Ir2Cr(In,Sn)
and IrRhCr(In,Sn) heusler alloys, we present ab-initio analysis of these alloys
by examining various properties to prove their stability. The stability of these
alloys can be inferred from different cohesive and formation energies as well
as positive phonon frequencies. Their electronic structure results indicate that
they are semi-metals in nature. The magnetic moments are computed using the Slater-Pauling
formula and exhibit a high value, with the Cr atom contributing the most in all
alloys. Mulliken’s charge analysis results show that our alloys contain a range
of linkages, mainly ionic and covalent ones. The ductility and mechanical stability
of these alloys are confirmed by elastic constants viz. Poisson’s ratio, Pugh’s
ratio, and many different types of elastic moduli.

text: The use of multimodal readout mechanisms next to label-free real-time monitoring
of biomolecular interactions can provide valuable insight into surface-based reaction
mechanisms. To this end, the combination of an electrolyte-gated field-effect
transistor (EG-FET) with a fiber optic-coupled surface plasmon resonance (FO-SPR)
probe serving as gate electrode has been investigated to deconvolute surface mass
and charge density variations associated to surface reactions. However, applying
an electrochemical potential on such gold-coated FO-SPR gate electrodes can induce
gradual morphological changes of the thin gold film, leading to an irreversible
blue-shift of the SPR wavelength and a substantial signal drift. We show that
mild annealing leads to optical and electronic signal stabilization (20-fold lower
signal drift than as-sputtered fiber optic gates) and improved overall analytical
performance characteristics. The thermal treatment prevents morphological changes
of the thin gold-film occurring during operation, hence providing reliable and
stable data immediately upon gate voltage application. Thus, the readout output
of both transducing principles, the optical FO-SPR and electronic EG-FET, stays
constant throughout the whole sensing time-window and the long-term effect of
thermal treatment is also improved, providing stable signals even after 1 year
of storage. Annealing should therefore be considered a necessary modification
for applying fiber optic gate electrodes in real-time multimodal investigations
of surface reactions at the solid-liquid interface.

text: High entropy alloys (HEAs) are highly suitable candidate catalysts for oxygen
evolution and reduction reactions (OER/ORR) as they offer numerous parameters
for optimizing the electronic structure and catalytic sites. Herein, FeCoNiMoW
HEA nanoparticles are synthesized using a solution‐based low‐temperature approach.
Such FeCoNiMoW nanoparticles show high entropy properties, subtle lattice distortions,
and modulated electronic structure, leading to superior OER performance with an
overpotential of 233 mV at 10 mA cm−2 and 276 mV at 100 mA cm−2.
Density functional theory calculations reveal the electronic structures of the
FeCoNiMoW active sites with an optimized d‐band center position that enables suitable
adsorption of OOH* intermediates and reduces the Gibbs free energy barrier in
the OER process. Aqueous zinc–air batteries (ZABs) based on this HEA demonstrate
a high open circuit potential of 1.59 V, a peak power density of 116.9 mW cm−2,
a specific capacity of 857 mAh gZn−1,
and excellent stability for over 660 h of continuous charge–discharge cycles.
Flexible and solid ZABs are also assembled and tested, displaying excellent charge–discharge
performance at different bending angles. This work shows the significance of 4d/5d
metal‐modulated electronic structure and optimized adsorption ability to improve
the performance of OER/ORR, ZABs, and beyond.

text: Low‐cost, safe, and environmental‐friendly rechargeable aqueous zinc‐ion batteries
(ZIBs) are promising as next‐generation energy storage devices for wearable electronics
among other applications. However, sluggish ionic transport kinetics and the unstable
electrode structure during ionic insertion/extraction hampers their deployment.
Herein, we propose a new cathode material based on a layered metal chalcogenide
(LMC), bismuth telluride (Bi2Te3), coated
with polypyrrole (PPy). Taking advantage of the PPy coating, the Bi2Te3@PPy
composite presents strong ionic absorption affinity, high oxidation resistance,
and high structural stability. The ZIBs based on Bi2Te3@PPy
cathodes exhibit high capacities and ultra‐long lifespans of over 5000 cycles.
They also present outstanding stability even under bending. In addition, we analyze
here the reaction mechanism using in situ X‐ray diffraction, X‐ray photoelectron
spectroscopy, and computational tools and demonstrate that, in the aqueous system,
Zn2+ is not inserted into the cathode as previously assumed.
In contrast, proton charge storage dominates the process. Overall, this work not
only shows the great potential of LMCs as ZIBs cathode materials and the advantages
of PPy coating, but also clarifies the charge/discharge mechanism in rechargeable
ZIBs based on LMCs.

text: Lithium–sulfur batteries are regarded as an advantageous option for meeting
the growing demand for high-energy-density storage, but their commercialization
relies on solving the current limitations of both sulfur cathodes and lithium
metal anodes. In this scenario, the implementation of lithium sulfide (Li2S) cathodes
compatible with alternative anode materials such as silicon has the potential
to alleviate the safety concerns associated with lithium metal. In this direction,
here, we report a sulfur cathode based on Li2S nanocrystals grown on a catalytic
host consisting of CoFeP nanoparticles supported on tubular carbon nitride. Nanosized
Li2S is incorporated into the host by a scalable liquid infiltration–evaporation
method. Theoretical calculations and experimental results demonstrate that the
CoFeP–CN composite can boost the polysulfide adsorption/conversion reaction kinetics
and strongly reduce the initial overpotential activation barrier by stretching
the Li–S bonds of Li2S. Besides, the ultrasmall size of the Li2S particles in
the Li2S–CoFeP–CN composite cathode facilitates the initial activation. Overall,
the Li2S–CoFeP–CN electrodes exhibit a low activation barrier of 2.56 V, a high
initial capacity of 991 mA h gLi2S–1, and outstanding cyclability with a small
fading rate of 0.029% per cycle over 800 cycles. Moreover, Si/Li2S full cells
are assembled using the nanostructured Li2S–CoFeP–CN cathode and a prelithiated
anode based on graphite-supported silicon nanowires. These Si/Li2S cells demonstrate
high initial discharge capacities above 900 mA h gLi2S–1 and good cyclability
with a capacity fading rate of 0.28% per cycle over 150 cycles.

text: Developing cost-effective and high-performance thermoelectric (TE) materials
to assemble efficient TE devices presents a multitude of challenges and opportunities.
Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant
elements. However, the challenge lies in its poor electrical conductivity. Herein,
an efficient and scalable solution-based approach is developed to synthesize high-quality
Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement
and annealing treatments, the dried powders are consolidated into dense pellets,
and their TE properties are investigated. Pb doping effectively increases the
charge carrier concentration, resulting in a significant increase in electrical
conductivity, while the Seebeck coefficients remain consistently high. The calculated
band structure shows that Pb doping induces band convergence, thereby increasing
the effective mass. Furthermore, the large ionic radius of Pb2+ results in the
generation of additional point and plane defects and interphases, dramatically
enhancing phonon scattering, which significantly decreases the lattice thermal
conductivity at high temperatures. Overall, a maximum figure of merit (zTmax)
≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold
increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based
materials produced by solid-state, demonstrating advantages of versatility and
cost-effectiveness using a solution-based technology.

text: The effects of the partial V-substitution for Ag on the thermoelectric (TE)
properties are investigated for a flexible semiconducting compound Ag2S0.55Se0.45.
Density functional theory calculations predict that such a partial V-substitution
constructively modifies the electronic structure near the bottom of the conduction
band to improve the TE performance. The synthesized Ag1.97V0.03S0.55Se0.45 is
found to possess a TE dimensionless figure-of-merit (ZT) of 0.71 at 350 K with
maintaining its flexible nature. This ZT value is relatively high in comparison
with those reported for flexible TE materials below 360 K. The increase in the
ZT value is caused by the enhanced absolute value of the Seebeck coefficient with
less significant variation in electrical resistivity. The high ZT value with the
flexible nature naturally allows us to employ the Ag1.97V0.03S0.55Se0.45 as a
component of flexible TE generators.

text: We report on a simple surfactant/template free chemical route for the synthesis
of semi-polycrystalline polyaniline-graphite (SPani-graphite) composite and its
application as an electroactive material in electrochemical charge storage. The
synthesized material exhibits well-defined poly-crystallographic lattices in high
resolution transmission electron micrographs and sharp peaks in x-ray diffraction
spectra suggesting crystalline nature of the material. The specific capacitance
computed from the galvanostatic charge-discharge (GCD) data obtained from 3-electrode
cell configuration using 1 M aq. Na2SO4 as an electrolyte was 111.4 F g−1 at a
current density of 0.1 A g−1 which rises to 269 F g−1 at an elevated current density
of 1.0 A g−1. A similar pattern of increase in the specific capacitance values
with an increase in the current density was observed in the results obtained from
2-electrode symmetric device configuration using polymer gel electrolyte (xanthan
gum in 1 M aq. Na2SO4). The specific capacitance computed from the GCD data obtained
from the device configuration was 20 F g−1 at the current density of 1.0 A g−1.
The device delivers an energy density of 1.7 Wh kg−1 and a power density of 2.48
kWh kg−1 at an applied current density of 0.5 A g−1 suggesting an excellent rate
capability and power management. In addition, the device exhibits ⁓92 % specific
capacitance retention up to 8000 continuous GCD cycles and ⁓80 % coulombic efficiency
up to 10,000 continuous GCD cycles indicating excellent cycling stability. The
unique feature of increasing specific capacitance with respect to applied current
density is attributed to the presence of semi-polycrystalline phases in the SPani-graphite
matrix. The material behaves as a surface redox supercapacitor and its unique
mechanism of charge storage is discussed in detail in the article.

text: Lead sulfide (PbS) presents large potential in thermoelectric application
due to its earth-abundant S element. However, its inferior average ZT (ZTave)
value makes PbS less competitive with its analogs PbTe and PbSe. To promote its
thermoelectric performance, this study implements strategies of continuous Se
alloying and Cu interstitial doping to synergistically tune thermal and electrical
transport properties in n-type PbS. First, the lattice parameter of 5.93 Å in
PbS is linearly expanded to 6.03 Å in PbS0.5Se0.5 with increasing Se alloying
content. This expanded lattice in Se-alloyed PbS not only intensifies phonon scattering
but also facilitates the formation of Cu interstitials. Based on the PbS0.6Se0.4
content with the minimal lattice thermal conductivity, Cu interstitials are introduced
to improve the electron density, thus boosting the peak power factor, from 3.88 μW cm−1 K−2
in PbS0.6Se0.4 to 20.58 μW cm−1 K−2 in PbS0.6Se0.4−1%Cu. Meanwhile, the lattice
thermal conductivity in PbS0.6Se0.4−x%Cu (x = 0–2) is further suppressed due to
the strong strain field caused by Cu interstitials. Finally, with the lowered
thermal conductivity and high electrical transport properties, a peak ZT ~1.1
and ZTave ~0.82 can be achieved in PbS0.6Se0.4 − 1%Cu at 300–773K, which outperforms
previously reported n-type PbS.

text: Access to a blossoming library of colloidal nanomaterials provides building
blocks for complex assembled materials. The journey to bring these prospects to
fruition stands to benefit from the application of advanced processing methods.
Epitaxially connected nanocrystal (or quantum dot) superlattices present a captivating
model system for mesocrystals with intriguing emergent properties. The conventional
processing approach to creating these materials involves assembling and attaching
the constituent nanocrystals at the interface between two immiscible fluids. Processing
small liquid volumes of the colloidal nanocrystal solution involves several complexities
arising from the concurrent spreading, evaporation, assembly, and attachment.
The ability of inkjet printers to deliver small (typically picoliter) liquid volumes
with precise positioning is attractive to advance fundamental insights into the
processing science, and thereby potentially enable new routes to incorporate the
epitaxially connected superlattices into technology platforms. In this study,
we identified the processing window of opportunity, including nanocrystal ink
formulation and printing approach to enable delivery of colloidal nanocrystals
from an inkjet nozzle onto the surface of a sessile droplet of the immiscible
subphase. We demonstrate how inkjet printing can be scaled-down to enable the
fabrication of epitaxially connected superlattices on patterned sub-millimeter
droplets. We anticipate that insights from this work will spur on future advances
to enable more mechanistic insights into the assembly processes and new avenues
to create high-fidelity superlattices.

text: SnSe has emerged as one of the most promising materials for thermoelectric
energy conversion due to its extraordinary performance in its single-crystal form
and its low-cost constituent elements. However, to achieve an economic impact,
the polycrystalline counterpart needs to replicate the performance of the single
crystal. Herein, we optimize the thermoelectric performance of polycrystalline
SnSe produced by consolidating solution-processed and surface-engineered SnSe
particles. In particular, the SnSe particles are coated with CdSe molecular complexes
that crystallize during the sintering process, forming CdSe nanoparticles. The
presence of CdSe nanoparticles inhibits SnSe grain growth during the consolidation
step due to Zener pinning, yielding a material with a high density of grain boundaries.
Moreover, the resulting SnSe–CdSe nanocomposites present a large number of defects
at different length scales, which significantly reduce the thermal conductivity.
The produced SnSe–CdSe nanocomposites exhibit thermoelectric figures of merit
up to 2.2 at 786 K, which is among the highest reported for solution-processed
SnSe.

text: A novel multivariable system, combining a transistor with fiber optic-based
surface plasmon resonance spectroscopy with the gate electrode simultaneously
acting as the fiber optic sensor surface, is reported. The dual-mode sensor allows
for discrimination of mass and charge contributions for binding assays on the
same sensor surface. Furthermore, we optimize the sensor geometry by investigating
the influence of the fiber area to transistor channel area ratio and distance.
We show that larger fiber optic tip diameters are favorable for electronic and
optical signals and demonstrate the reversibility of plasmon resonance wavelength
shifts after electric field application. As a proof of principle, a layer-by-layer
assembly of polyelectrolytes is performed to benchmark the system against multivariable
sensing platforms with planar surface plasmon resonance configurations. Furthermore,
the biosensing performance is assessed using a thrombin binding assay with surface-immobilized
aptamers as receptors, allowing for the detection of medically relevant thrombin
concentrations.

text: SnTe is a promising Pb-free thermoelectric (TE) material with high electrical
conductivity. We discovered the synergistic effect of Bi2O3 on enhancing the average
power factor (PF) and overall ZT value of the SnTe-based thermoelectric material.
The introduction of Bi2O3 forms plenty of SnO2, Bi2O3, and Bi-rich nanoprecipitates.
These interfaces between the SnTe matrix and the nanoprecipitates can enhance
the average PF through the energy filtering effect. On the other hand, abundant
and diverse nanoprecipitates can significantly diminish the lattice thermal conductivity
(κlat) through enhanced phonon scattering. The synergistic effect of Bi2O3 resulted
in a maximum ZT (ZTmax) value of 0.9 at SnTe-2% Bi2O3 and an average ZT (ZTave)
value of 0.4 for SnTe-4% Bi2O3 from 300 K to 823 K. The work provides an excellent
reference to develop non-toxic high-performance TE materials.

text: Tin selenide (SnSe) is considered a robust candidate for thermoelectric applications
due to its very high thermoelectric figure of merit, ZT, with values of 2.6 in
p-type and 2.8 in n-type single crystals. Sn has been replaced with various lower
group dopants to achieve successful p-type doping in SnSe with high ZT values.
A known, facile, and powerful alternative way to introduce a hole carrier is to
use a natural single Sn vacancy, VSn. Through transport and scanning tunneling
microscopy studies, we discovered that VSn are dominant in high-quality (slow
cooling rate) SnSe single crystals, while multiple vacancies, Vmulti, are dominant
in low-quality (high cooling rate) single crystals. Surprisingly, both VSn and
Vmulti help to increase the power factors of SnSe, whereas samples with dominant
VSn have superior thermoelectric properties in SnSe single crystals. Additionally,
the observation that Vmulti are good p-type sources observed in relatively low-quality
single crystals is useful in thermoelectric applications because polycrystalline
SnSe can be used due to its mechanical strength; this substance is usually fabricated
at very high cooling speeds.

text: The precursor conversion chemistry and surface chemistry of Cu3N and Cu3PdN
nanocrystals are unknown or contested. Here, we first obtain phase-pure, colloidally
stable nanocubes. Second, we elucidate the pathway by which copper(II) nitrate
and oleylamine form Cu3N. We find that oleylamine is both a reductant and a nitrogen
source. Oleylamine is oxidized by nitrate to a primary aldimine, which reacts
further with excess oleylamine to a secondary aldimine, eliminating ammonia. Ammonia
reacts with CuI to form Cu3N. Third, we investigated the surface chemistry and
find a mixed ligand shell of aliphatic amines and carboxylates (formed in situ).
While the carboxylates appear tightly bound, the amines are easily desorbed from
the surface. Finally, we show that doping with palladium decreases the band gap
and the material becomes semi-metallic. These results bring insight into the chemistry
of metal nitrides and might help the development of other metal nitride nanocrystals.

text: 'The broad implementation of thermoelectricity requires high-performance and
low-cost materials. One possibility is employing surfactant-free solution synthesis
to produce nanopowders. We propose the strategy of functionalizing “naked” particles’
surface by inorganic molecules to control the nanostructure and, consequently,
thermoelectric performance. In particular, we use bismuth thiolates to functionalize
surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates
decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1)
carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement
and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity
reduction by small grain domains, grain boundaries and nanostructuration. Overall,
the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average
z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed
SnTe.'

text: Thermoelectric technology requires synthesizing complex materials where not
only the crystal structure but also other structural features such as defects,
grain size and orientation, and interfaces must be controlled. To date, conventional
solid-state techniques are unable to provide this level of control. Herein, we
present a synthetic approach in which dense inorganic thermoelectric materials
are produced by the consolidation of well-defined nanoparticle powders. The idea
is that controlling the characteristics of the powder allows the chemical transformations
that take place during consolidation to be guided, ultimately yielding inorganic
solids with targeted features. Different from conventional methods, syntheses
in solution can produce particles with unprecedented control over their size,
shape, crystal structure, composition, and surface chemistry. However, to date,
most works have focused only on the low-cost benefits of this strategy. In this
perspective, we first cover the opportunities that solution processing of the
powder offers, emphasizing the potential structural features that can be controlled
by precisely engineering the inorganic core of the particle, the surface, and
the organization of the particles before consolidation. We then discuss the challenges
of this synthetic approach and more practical matters related to solution processing.
Finally, we suggest some good practices for adequate knowledge transfer and improving
reproducibility among different laboratories.

text: A versatile, scalable, room temperature and surfactant-free route for the
synthesis of metal chalcogenide nanoparticles in aqueous solution is detailed
here for the production of PbS and Cu-doped PbS nanoparticles. Subsequently, nanoparticles
are annealed in a reducing atmosphere to remove surface oxide, and consolidated
into dense polycrystalline materials by means of spark plasma sintering. By characterizing
the transport properties of the sintered material, we observe the annealing step
and the incorporation of Cu to play a key role in promoting the thermoelectric
performance of PbS. The presence of Cu allows improving the electrical conductivity
by increasing the charge carrier concentration and simultaneously maintaining
a large charge carrier mobility, which overall translates into record power factors
at ambient temperature, 2.3 mWm-1K−2. Simultaneously, the lattice thermal conductivity
decreases with the introduction of Cu, leading to a record high ZT = 0.37 at room
temperature and ZT = 1.22 at 773 K. Besides, a record average ZTave = 0.76 is
demonstrated in the temperature range 320–773 K for n-type Pb0.955Cu0.045S.

text: High-entropy materials offer numerous advantages as catalysts, including a
flexible composition to tune the catalytic activity and selectivity and a large
variety of adsorption/reaction sites for multistep or multiple reactions. Herein,
we report on the synthesis, properties, and electrocatalytic performance of an
amorphous high-entropy boride based on abundant transition metals, CoFeNiMnZnB.
This metal boride provides excellent performance toward the oxygen evolution reaction
(OER), including a low overpotential of 261 mV at 10 mA cm–2, a reduced Tafel
slope of 56.8 mV dec–1, and very high stability. The outstanding OER performance
of CoFeNiMnZnB is attributed to the synergistic interactions between the different
metals, the leaching of Zn ions, the generation of oxygen vacancies, and the in
situ formation of an amorphous oxyhydroxide at the CoFeNiMnZnB surface during
the OER.

text: Thermoelectric materials allow for direct conversion between heat and electricity,
offering the potential for power generation. The average dimensionless figure
of merit ZTave determines device efficiency. N-type tin selenide crystals exhibit
outstanding three-dimensional charge and two-dimensional phonon transport along
the out-of-plane direction, contributing to a high maximum figure of merit Zmax
of ~3.6 × 10−3 per kelvin but a moderate ZTave of ~1.1. We found an attractive
high Zmax of ~4.1 × 10−3 per kelvin at 748 kelvin and a ZTave of ~1.7 at 300 to
773 kelvin in chlorine-doped and lead-alloyed tin selenide crystals by phonon-electron
decoupling. The chlorine-induced low deformation potential improved the carrier
mobility. The lead-induced mass and strain fluctuations reduced the lattice thermal
conductivity. Phonon-electron decoupling plays a critical role to achieve high-performance
thermoelectrics.

text: The growing demand of thermal management in various fields such as miniaturized
5G chips has motivated researchers to develop new and high-performance solid-state
refrigeration technologies, typically including multicaloric and thermoelectric
(TE) cooling. Among them, TE cooling has attracted huge attention owing to its
advantages of rapid response, large cooling temperature difference, high stability,
and tunable device size. Bi2Te3-based alloys have long been the only commercialized
TE cooling materials, while novel systems SnSe and Mg3(Bi,Sb)2 have recently been
discovered as potential candidates. However, challenges and problems still require
to be summarized and further resolved for realizing better cooling performance.
In this review, we systematically investigate TE cooling from its internal mechanism,
crucial parameters, to device design and applications. Furthermore, we summarize
the current optimization strategies for existing TE cooling materials, and finally
provide some personal prospects especially the material-planification concept
on future research on establishing better TE cooling.

text: Ligands are a fundamental part of nanocrystals. They control and direct nanocrystal
syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’
chemical reactivity and electronic structure. Surface chemistry is thus crucial
to understand nanocrystal properties and functionality. Here, we investigate the
synthesis of metal oxide nanocrystals (CeO2-x, ZnO, and NiO) from metal nitrate
precursors, in the presence of oleylamine ligands. Surprisingly, the nanocrystals
are capped exclusively with a fatty acid instead of oleylamine. Analysis of the
reaction mixtures with nuclear magnetic resonance spectroscopy revealed several
reaction byproducts and intermediates that are common to the decomposition of
Ce, Zn, Ni, and Zr nitrate precursors. Our evidence supports the oxidation of
alkylamine and formation of a carboxylic acid, thus unraveling this counterintuitive
surface chemistry.

text: Cesium lead halides have intrinsically unstable crystal lattices and easily
transform within perovskite and nonperovskite structures. In this work, we explore
the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS
at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6
nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into
the PbS lattice with a consequent increase in the concentration of free charge
carriers. This new doping strategy enables the adjustment of the density of charge
carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for
doping other nanocrystal-based semiconductors.

text: 'The precise engineering of thermoelectric materials using nanocrystals as
their building blocks has proven to be an excellent strategy to increase energy
conversion efficiency. Here we present a synthetic route to produce Sb-doped PbS
colloidal nanoparticles. These nanoparticles are then consolidated into nanocrystalline
PbS:Sb using spark plasma sintering. We demonstrate that the introduction of Sb
significantly influences the size, geometry, crystal lattice and especially the
carrier concentration of PbS. The increase of charge carrier concentration achieved
with the introduction of Sb translates into an increase of the electrical and
thermal conductivities and a decrease of the Seebeck coefficient. Overall, PbS:Sb
nanomaterial were characterized by two-fold higher thermoelectric figures of merit
than undoped PbS. '

text: SnSe, a wide-bandgap semiconductor, has attracted significant attention from
the thermoelectric (TE) community due to its outstanding TE performance deriving
from the ultralow thermal conductivity and advantageous electronic structures.
Here, we promoted the TE performance of n-type SnSe polycrystals through bandgap
engineering and vacancy compensation. We found that PbTe can significantly reduce
the wide bandgap of SnSe to reduce the impurity transition energy, largely enhancing
the carrier concentration. Also, PbTe-induced crystal symmetry promotion increases
the carrier mobility, preserving large Seebeck coefficient. Consequently, a maximum
ZT of ∼1.4 at 793 K is obtained in Br doped SnSe–13%PbTe. Furthermore, we found
that extra Sn in n-type SnSe can compensate for the intrinsic Sn vacancies and
form electron donor-like metallic Sn nanophases. The Sn nanophases near the grain
boundary could also reduce the intergrain energy barrier which largely enhances
the carrier mobility. As a result, a maximum ZT value of ∼1.7 at 793 K and an
average ZT (ZTave) of ∼0.58 in 300–793 K are achieved in Br doped Sn1.08Se–13%PbTe.
Our findings provide a novel strategy to promote the TE performance in wide-bandgap
semiconductors.

summer of 2020. By the end of the year, the series had attracted over 850 participants
from 46 countries. In this Nano Focus, we describe the process of organizing the
News in Nanocrystals seminar series; discuss its growth, emphasizing what the
organizers have learned in terms of diversity and accessibility; and provide an
outlook for the next steps and future opportunities. This summary and analysis
of experiences and learned lessons are intended to inform the broader scientific
community, especially those who are looking for avenues to continue fostering
discussion and scientific engagement virtually, both during the pandemic and after.

text: Solution synthesis of particles emerged as an alternative to prepare thermoelectric
materials with less demanding processing conditions than conventional solid-state
synthetic methods. However, solution synthesis generally involves the presence
of additional molecules or ions belonging to the precursors or added to enable
solubility and/or regulate nucleation and growth. These molecules or ions can
end up in the particles as surface adsorbates and interfere in the material properties.
This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically
adsorbed in SnSe particles synthesized in water and play a crucial role not only
in directing the material nano/microstructure but also in determining the transport
properties of the consolidated material. In dense pellets prepared by sintering
SnSe particles, Na remains within the crystal lattice as dopant, in dislocations,
precipitates, and forming grain boundary complexions. These results highlight
the importance of considering all the possible unintentional impurities to establish
proper structure-property relationships and control material properties in solution-processed
thermoelectric materials.

text: Thermoelectric materials enable the direct conversion between heat and electricity.
SnTe is a promising candidate due to its high charge transport performance. Here,
we prepared SnTe nanocomposites by employing an aqueous method to synthetize SnTe
nanoparticles (NP), followed by a unique surface treatment prior NP consolidation.
This synthetic approach allowed optimizing the charge and phonon transport synergistically.
The novelty of this strategy was the use of a soluble PbS molecular complex prepared
using a thiol-amine solvent mixture that upon blending is adsorbed on the SnTe
NP surface. Upon consolidation with spark plasma sintering, SnTe-PbS nanocomposite
is formed. The presence of PbS complexes significantly compensates for the Sn
vacancy and increases the average grain size of the nanocomposite, thus improving
the carrier mobility. Moreover, lattice thermal conductivity is also reduced by
the Pb and S-induced mass and strain fluctuation. As a result, an enhanced ZT
of ca. 0.8 is reached at 873 K. Our finding provides a novel strategy to conduct
rational surface treatment on NP-based thermoelectrics.

text: For many years, fullerene derivatives have been the main n-type material of
organic electronics and optoelectronics. Recently, fullerene derivatives functionalized
with ethylene glycol (EG) side chains have been showing important properties such
as enhanced dielectric constants, facile doping and enhanced self-assembly capabilities.
Here, we have prepared field-effect transistors using a series of these fullerene
derivatives equipped with EG side chains of different lengths. Transport data
show the beneficial effect of increasing the EG side chain. In order to understand
the material properties, full structural determination of these fullerene derivatives
has been achieved by coupling the X-ray data with molecular dynamics (MD) simulations.
The increase in transport properties is paired with the formation of extended
layered structures, efficient molecular packing and an increase in the crystallite
alignment. The layer-like structure is composed of conducting layers, containing
of closely packed C60 balls approaching the inter-distance of 1 nm, that are separated
by well-defined EG layers, where the EG chains are rather splayed with the chain
direction almost perpendicular to the layer normal. Such a layered structure appears
highly ordered and highly aligned with the C60 planes oriented parallel to the
substrate in the thin film configuration. The order inside the thin film increases
with the EG chain length, allowing the systems to achieve mobilities as high as
0.053 cm2 V−1 s−1. Our work elucidates the structure of these interesting semiconducting
organic molecules and shows that the synergistic use of X-ray structural analysis
and MD simulations is a powerful tool to identify the structure of thin organic
films for optoelectronic applications.

text: Thermoelectric materials are engines that convert heat into an electrical
current. Intuitively, the efficiency of this process depends on how many electrons
(charge carriers) can move and how easily they do so, how much energy those moving
electrons transport, and how easily the temperature gradient is maintained. In
terms of material properties, an excellent thermoelectric material requires a
high electrical conductivity σ, a high Seebeck coefficient S (a measure of the
induced thermoelectric voltage as a function of temperature gradient), and a low
thermal conductivity κ. The challenge is that these three properties are strongly
interrelated in a conflicting manner (1). On page 722 of this issue, Roychowdhury
et al. (2) have found a way to partially break these ties in silver antimony telluride
(AgSbTe2) with the addition of cadmium (Cd) cations, which increase the ordering
in this inherently disordered thermoelectric material.

text: The cost-effective conversion of low-grade heat into electricity using thermoelectric
devices requires developing alternative materials and material processing technologies
able to reduce the currently high device manufacturing costs. In this direction,
thermoelectric materials that do not rely on rare or toxic elements such as tellurium
or lead need to be produced using high-throughput technologies not involving high
temperatures and long processes. Bi2Se3 is an obvious possible Te-free alternative
to Bi2Te3 for ambient temperature thermoelectric applications, but its performance
is still low for practical applications, and additional efforts toward finding
proper dopants are required. Here, we report a scalable method to produce Bi2Se3
nanosheets at low synthesis temperatures. We studied the influence of different
dopants on the thermoelectric properties of this material. Among the elements
tested, we demonstrated that Sn doping resulted in the best performance. Sn incorporation
resulted in a significant improvement to the Bi2Se3 Seebeck coefficient and a
reduction in the thermal conductivity in the direction of the hot-press axis,
resulting in an overall 60% improvement in the thermoelectric figure of merit
of Bi2Se3.

text: The high processing cost, poor mechanical properties and moderate performance
of Bi2Te3–based alloys used in thermoelectric devices limit the cost-effectiveness
of this energy conversion technology. Towards solving these current challenges,
in the present work, we detail a low temperature solution-based approach to produce
Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach
consists in combining proper ratios of colloidal nanoparticles and to consolidate
the resulting mixture into nanocomposites using a hot press. The transport properties
of the nanocomposites are characterized and compared with those of pure Bi2Te3
nanomaterials obtained following the same procedure. In contrast with most previous
works, the presence of Cu2-xTe nanodomains does not result in a significant reduction
of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which
is already very low. However, the introduction of Cu2-xTe yields a nearly threefold
increase of the power factor associated to a simultaneous increase of the Seebeck
coefficient and electrical conductivity at temperatures above 400 K. Taking into
account the band alignment of the two materials, we rationalize this increase
by considering that Cu2-xTe nanostructures, with a relatively low electron affinity,
are able to inject electrons into Bi2Te3, enhancing in this way its electrical
conductivity. The simultaneous increase of the Seebeck coefficient is related
to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains
associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3
heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe
nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure
of merit of Bi2Te3.

text: Copper chalcogenides are outstanding thermoelectric materials for applications
in the medium-high temperature range. Among different chalcogenides, while Cu2−xSe
is characterized by higher thermoelectric figures of merit, Cu2−xS provides advantages
in terms of low cost and element abundance. In the present work, we investigate
the effect of different dopants to enhance the Cu2−xS performance and also its
thermal stability. Among the tested options, Pb-doped Cu2−xS shows the highest
improvement in stability against sulfur volatilization. Additionally, Pb incorporation
allows tuning charge carrier concentration, which enables a significant improvement
of the power factor. We demonstrate here that the introduction of an optimal additive
amount of just 0.3% results in a threefold increase of the power factor in the
middle-temperature range (500–800 K) and a record dimensionless thermoelectric
figure of merit above 2 at 880 K.

text: Composite materials offer numerous advantages in a wide range of applications,
including thermoelectrics. Here, semiconductor–metal composites are produced by
just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution
and at room temperature with a metallic Cu powder. The obtained blend is annealed
in a reducing atmosphere and afterward consolidated into dense polycrystalline
pellets through spark plasma sintering (SPS). We observe that, during the annealing
process, the presence of metallic copper activates a partial reduction of the
PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic
lead during the SPS process habilitates the liquid-phase sintering of the composite.
Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites,
and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate
that the presence of metallic lead decisively contributes to a strong increase
of the charge carrier concentration through spillover of charge carriers enabled
by the low work function of lead. The increase in charge carrier concentration
translates into much higher electrical conductivities and moderately lower Seebeck
coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2
at ambient temperature, well above those of PbS and PbS + CuxS. Additionally,
the presence of multiple phases in the final composite results in a notable decrease
in the lattice thermal conductivity. Overall, the introduction of metallic copper
in the initial blend results in a significant improvement of the thermoelectric
performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT
= 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides,
an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.

text: Cu2–xS has become one of the most promising thermoelectric materials for application
in the middle-high temperature range. Its advantages include the abundance, low
cost, and safety of its elements and a high performance at relatively elevated
temperatures. However, stability issues limit its operation current and temperature,
thus calling for the optimization of the material performance in the middle temperature
range. Here, we present a synthetic protocol for large scale production of covellite
CuS nanoparticles at ambient temperature and atmosphere, and using water as a
solvent. The crystal phase and stoichiometry of the particles are afterward tuned
through an annealing process at a moderate temperature under inert or reducing
atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral
crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal
Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed
in argon to transform to the cubic phase at ca. 400 K, while the material annealed
in the presence of hydrogen undergoes two phase transitions, first to hexagonal
and then to the cubic structure. The annealing atmosphere, temperature, and time
allow adjustment of the density of copper vacancies and thus tuning of the charge
carrier concentration and material transport properties. In this direction, the
material annealed under Ar is characterized by higher electrical conductivities
but lower Seebeck coefficients than the material annealed in the presence of hydrogen.
By optimizing the charge carrier concentration through the annealing time, Cu2–xS
with record figures of merit in the middle temperature range, up to 1.41 at 710
K, is obtained. We finally demonstrate that this strategy, based on a low-cost
and scalable solution synthesis process, is also suitable for the production of
high performance Cu2–xS layers using high throughput and cost-effective printing
technologies.

text: 'Research on two-dimensional (2D) materials has been explosively increasing
in last seventeen years in varying subjects including condensed matter physics,
electronic engineering, materials science, and chemistry since the mechanical
exfoliation of graphene in 2004. Starting from graphene, 2D materials now have
become a big family with numerous members and diverse categories. The unique structural
features and physicochemical properties of 2D materials make them one class of
the most appealing candidates for a wide range of potential applications. In particular,
we have seen some major breakthroughs made in the field of 2D materials in last
five years not only in developing novel synthetic methods and exploring new structures/properties
but also in identifying innovative applications and pushing forward commercialisation.
In this review, we provide a critical summary on the recent progress made in the
field of 2D materials with a particular focus on last five years. After a brief
background introduction, we first discuss the major synthetic methods for 2D materials,
including the mechanical exfoliation, liquid exfoliation, vapor phase deposition,
and wet-chemical synthesis as well as phase engineering of 2D materials belonging
to the field of phase engineering of nanomaterials (PEN). We then introduce the
superconducting/optical/magnetic properties and chirality of 2D materials along
with newly emerging magic angle 2D superlattices. Following that, the promising
applications of 2D materials in electronics, optoelectronics, catalysis, energy
storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially.
Thereafter, we present the theoretic calculations and simulations of 2D materials.
Finally, after concluding the current progress, we provide some personal discussions
on the existing challenges and future outlooks in this rapidly developing field. '

text: Nanomaterials produced from the bottom-up assembly of nanocrystals may incorporate
∼1020–1021 cm–3 not fully coordinated surface atoms, i.e., ∼1020–1021 cm–3 potential
donor or acceptor states that can strongly affect transport properties. Therefore,
to exploit the full potential of nanocrystal building blocks to produce functional
nanomaterials and thin films, a proper control of their surface chemistry is required.
Here, we analyze how the ligand stripping procedure influences the charge and
heat transport properties of sintered PbSe nanomaterials produced from the bottom-up
assembly of colloidal PbSe nanocrystals. First, we show that the removal of the
native organic ligands by thermal decomposition in an inert atmosphere leaves
relatively large amounts of carbon at the crystal interfaces. This carbon blocks
crystal growth during consolidation and at the same time hampers charge and heat
transport through the final nanomaterial. Second, we demonstrate that, by stripping
ligands from the nanocrystal surface before consolidation, nanomaterials with
larger crystal domains, lower porosity, and higher charge carrier concentrations
are obtained, thus resulting in nanomaterials with higher electrical and thermal
conductivities. In addition, the ligand displacement leaves the nanocrystal surface
unprotected, facilitating oxidation and chalcogen evaporation. The influence of
the ligand displacement on the nanomaterial charge transport properties is rationalized
here using a two-band model based on the standard Boltzmann transport equation
with the relaxation time approximation. Finally, we present an application of
the produced functional nanomaterials by modeling, fabricating, and testing a
simple PbSe-based thermoelectric device with a ring geometry.

text: Assemblies of colloidal semiconductor nanocrystals (NCs) in the form of thin
solid films leverage the size-dependent quantum confinement properties and the
wet chemical methods vital for the development of the emerging solution-processable
electronics, photonics, and optoelectronics technologies. The ability to control
the charge carrier transport in the colloidal NC assemblies is fundamental for
altering their electronic and optical properties for the desired applications.
Here we demonstrate a strategy to render the solids of narrow-bandgap NC assemblies
exclusively electron-transporting by creating a type-II heterojunction via shelling.
Electronic transport of molecularly cross-linked PbTe@PbS core@shell NC assemblies
is measured using both a conventional solid gate transistor and an electric-double-layer
transistor, as well as compared with those of core-only PbTe NCs. In contrast
to the ambipolar characteristics demonstrated by many narrow-bandgap NCs, the
core@shell NCs exhibit exclusive n-type transport, i.e., drastically suppressed
contribution of holes to the overall transport. The PbS shell that forms a type-II
heterojunction assists the selective carrier transport by heavy doping of electrons
into the PbTe-core conduction level and simultaneously strongly localizes the
holes within the NC core valence level. This strongly enhanced n-type transport
makes these core@shell NCs suitable for applications where ambipolar characteristics
should be actively suppressed, in particular, for thermoelectric and electron-transporting
layers in photovoltaic devices.

text: In the present work, we report a solution-based strategy to produce crystallographically
textured SnSe bulk nanomaterials and printed layers with optimized thermoelectric
performance in the direction normal to the substrate. Our strategy is based on
the formulation of a molecular precursor that can be continuously decomposed to
produce a SnSe powder or printed into predefined patterns. The precursor formulation
and decomposition conditions are optimized to produce pure phase 2D SnSe nanoplates.
The printed layer and the bulk material obtained after hot press displays a clear
preferential orientation of the crystallographic domains, resulting in an ultralow
thermal conductivity of 0.55 W m–1 K–1 in the direction normal to the substrate.
Such textured nanomaterials present highly anisotropic properties with the best
thermoelectric performance in plane, i.e., in the directions parallel to the substrate,
which coincide with the crystallographic bc plane of SnSe. This is an unfortunate
characteristic because thermoelectric devices are designed to create/harvest temperature
gradients in the direction normal to the substrate. We further demonstrate that
this limitation can be overcome with the introduction of small amounts of tellurium
in the precursor. The presence of tellurium allows one to reduce the band gap
and increase both the charge carrier concentration and the mobility, especially
the cross plane, with a minimal decrease of the Seebeck coefficient. These effects
translate into record out of plane ZT values at 800 K.

text: Direct ethanol fuel cells (DEFCs) show a huge potential to power future electric
vehicles and portable electronics, but their deployment is currently limited by
the unavailability of proper electrocatalysis for the ethanol oxidation reaction
(EOR). In this work, we engineer a new electrocatalyst by incorporating phosphorous
into a palladium-tin alloy and demonstrate a significant performance improvement
toward EOR. We first detail a synthetic method to produce Pd2Sn:P nanocrystals
that incorporate 35% of phosphorus. These nanoparticles are supported on carbon
black and tested for EOR. Pd2Sn:P/C catalysts exhibit mass current densities up
to 5.03 A mgPd−1, well above those of Pd2Sn/C, PdP2/C and Pd/C reference catalysts.
Furthermore, a twofold lower Tafel slope and a much longer durability are revealed
for the Pd2Sn:P/C catalyst compared with Pd/C. The performance improvement is
rationalized with the aid of density functional theory (DFT) calculations considering
different phosphorous chemical environments. Depending on its oxidation state,
surface phosphorus introduces sites with low energy OH− adsorption and/or strongly
influences the electronic structure of palladium and tin to facilitate the oxidation
of the acetyl to acetic acid, which is considered the EOR rate limiting step.
DFT calculations also points out that the durability improvement of Pd2Sn:P/C
catalyst is associated to the promotion of OH adsorption that accelerates the
oxidation of intermediate poisoning COads, reactivating the catalyst surface.

text: "Appropriately designed nanocomposites allow improving the thermoelectric
performance by several mechanisms, including phonon scattering, modulation doping
and energy filtering, while additionally promoting better mechanical properties
than those of crystalline materials. Here, a strategy for producing Bi2Te3–Cu2xTe
nanocomposites based on the consolidation of heterostructured nanoparticles is
described and the thermoelectric properties of the obtained materials are investigated.
We first detail a two-step solution-based process to produce Bi2Te3–Cu2xTe heteronanostructures,
based on the growth of Cu2xTe nanocrystals on the surface of Bi2Te3 nanowires.
We characterize the structural and chemical properties of the synthesized nanostructures
and of the nanocomposites\r\nproduced by hot-pressing the particles at moderate
temperatures. Besides, the transport properties of the nanocomposites are investigated
as a function of the amount of Cu introduced. Overall, the presence of Cu decreases
the material thermal conductivity through promotion of phonon scattering, modulates
the charge carrier concentration through electron spillover, and increases the
Seebeck coefficient through filtering of charge carriers at energy barriers. These
effects result in an improvement of over 50% of the thermoelectric figure of merit
of Bi2Te3."

text: 'Bimetallic nanoparticles with tailored size and specific composition have
shown promise as stable and selective catalysts for electrochemical reduction
of CO2 (CO2R) in batch systems. Yet, limited effort was devoted to understand
the effect of ligand coverage and postsynthesis treatments on CO2 reduction, especially
under industrially applicable conditions, such as at high currents (>100 mA/cm2)
using gas diffusion electrodes (GDE) and flow reactors. In this work, Cu–Ag core–shell
nanoparticles (11 ± 2 nm) were prepared with three different surface modes: (i)
capped with oleylamine, (ii) capped with monoisopropylamine, and (iii) surfactant-free
with a reducing borohydride agent; Cu–Ag (OAm), Cu–Ag (MIPA), and Cu–Ag (NaBH4),
respectively. The ligand exchange and removal was evidenced by infrared spectroscopy
(ATR-FTIR) analysis, whereas high-resolution scanning transmission electron microscopy
(HAADF-STEM) showed their effect on the interparticle distance and nanoparticle
rearrangement. Later on, we developed a process-on-substrate method to track these
effects on CO2R. Cu–Ag (OAm) gave a lower on-set potential for hydrocarbon production,
whereas Cu–Ag (MIPA) and Cu–Ag (NaBH4) promoted syngas production. The electrochemical
impedance and surface area analysis on the well-controlled electrodes showed gradual
increases in the electrical conductivity and active surface area after each surface
treatment. We found that the increasing amount of the triple phase boundaries
(the meeting point for the electron–electrolyte–CO2 reactant) affect the required
electrode potential and eventually the C+2e̅/C2e̅ product ratio. This study highlights
the importance of the electron transfer to those active sites affected by the
capping agents—particularly on larger substrates that are crucial for their industrial
application.'

text: "Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed
tremendously, mostly because of their exceptional optoelectronic properties. Core@shell
NCs, in which one or more inorganic layers overcoat individual NCs, recently received
significant attention due to their remarkable optical characteristics. Reduced
Auger recombination, suppressed blinking, and enhanced carrier multiplication
are among the merits of core@shell NCs. Despite their importance in device development,
the influence of the shell and the surface modification of the core@shell NC assemblies
on the charge carrier transport remains a pertinent research objective. Type-II
PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated,
still exhibit instability of their electron \r\n ransport. Here, we demonstrate
the enhancement of electron transport and stability in PbTe@PbS core@shell NC
assemblies using iodide as a surface passivating ligand. The combination of the
PbS shelling and the use of the iodide ligand contributes to the addition of one
mobile electron for each core@shell NC. Furthermore, both electron mobility and
on/off current modulation ratio values of the core@shell NC field-effect transistor
are steady with the usage of iodide. Excellent stability in these exclusively
electron-transporting core@shell NCs paves the way for their utilization in electronic
devices. "

text: Methodologies that involve the use of nanoparticles as “artificial atoms”
to rationally build materials in a bottom-up fashion are particularly well-suited
to control the matter at the nanoscale. Colloidal synthetic routes allow for an
exquisite control over such “artificial atoms” in terms of size, shape, and crystal
phase as well as core and surface compositions. We present here a bottom-up approach
to produce Pb–Ag–K–S–Te nanocomposites, which is a highly promising system for
thermoelectric energy conversion. First, we developed a high-yield and scalable
colloidal synthesis route to uniform lead sulfide (PbS) nanorods, whose tips are
made of silver sulfide (Ag2S). We then took advantage of the large surface-to-volume
ratio to introduce a p-type dopant (K) by replacing native organic ligands with
K2Te. Upon thermal consolidation, K2Te-surface modified PbS–Ag2S nanorods yield
p-type doped nanocomposites with PbTe and PbS as major phases and Ag2S and Ag2Te
as embedded nanoinclusions. Thermoelectric characterization of such consolidated
nanosolids showed a high thermoelectric figure-of-merit of 1 at 620 K.

text: Indigoidine is a blue natural pigment, which can be efficiently synthetized
in E. coli. In addition to its antioxidant and antimicrobial activities indigoidine
due to its stability and deep blue color can find an application as an industrial,
environmentally friendly dye. Moreover, similarly to its counterpart regular indigo
dye, due to its molecular structure, indigoidine is an organic semiconductor.
Fully conjugated aromatic moiety and intermolecular hydrogen bonding of indigoidine
result in an unusually narrow bandgap for such a small molecule. This, in its
turn, result is tight molecular packing in the solid state and opens a path for
a wide range of application in organic and bio-electronics, such as electrochemical
and field effect transistors, organic solar cells, light and bio-sensors etc.

text: The bottom-up assembly of colloidal nanocrystals is a versatile methodology
to produce composite nanomaterials with precisely tuned electronic properties.
Beyond the synthetic control over crystal domain size, shape, crystal phase, and
composition, solution-processed nanocrystals allow exquisite surface engineering.
This provides additional means to modulate the nanomaterial characteristics and
particularly its electronic transport properties. For instance, inorganic surface
ligands can be used to tune the type and concentration of majority carriers or
to modify the electronic band structure. Herein, we report the thermoelectric
properties of SnTe nanocomposites obtained from the consolidation of surface-engineered
SnTe nanocrystals into macroscopic pellets. A CdSe-based ligand is selected to
(i) converge the light and heavy bands through partial Cd alloying and (ii) generate
CdSe nanoinclusions as a secondary phase within the SnTe matrix, thereby reducing
the thermal conductivity. These SnTe-CdSe nanocomposites possess thermoelectric
figures of merit of up to 1.3 at 850 K, which is, to the best of our knowledge,
the highest thermoelectric figure of merit reported for solution-processed SnTe.

text: In the present work, we detail a fast and simple solution-based method to
synthesize hexagonal SnSe2 nanoplates (NPLs) and their use to produce crystallographically
textured SnSe2 nanomaterials. We also demonstrate that the same strategy can be
used to produce orthorhombic SnSe nanostructures and nanomaterials. NPLs are grown
through a screw dislocation-driven mechanism. This mechanism typically results
in pyramidal structures, but we demonstrate here that the growth from multiple
dislocations results in flower-like structures. Crystallographically textured
SnSe2 bulk nanomaterials obtained from the hot pressing of these SnSe2 structures
display highly anisotropic charge and heat transport properties and thermoelectric
(TE) figures of merit limited by relatively low electrical conductivities. To
improve this parameter, SnSe2 NPLs are blended here with metal nanoparticles.
The electrical conductivities of the blends are significantly improved with respect
to bare SnSe2 NPLs, what translates into a three-fold increase of the TE Figure
of merit, reaching unprecedented ZT values up to 0.65.
