text: Silver selenide (Ag2Se) is a promising near-room-temperature thermoelectric
material, but its narrow stoichiometric window and β–α phase transition complicate
reproducible microstructure control. Here, we present a mismatch-assisted microstructure
engineering strategy in which Ag2Se particles are treated with polyanionic ZnSe
complexes and consolidated through the β–α transition to introduce ZnSe nanoprecipitates,
Ag2Se/ZnSe interfaces, and local strain fields. The crystallographic mismatch
between ZnSe and Ag2Se, together with the Zn2+/Ag+ size difference, amplifies
phase-transition-induced deformation and promotes high-density dislocations with
periodic strain modulations. This defect architecture suppresses grain coarsening,
removes excess Ag, limits Ag-interstitial formation, and reduces lattice thermal
conductivity through lattice softening and multiscale phonon scattering. Ag2Se–4%ZnSe
nanocomposites achieve a peak zTmax of 1.13 at 369 K and a zTavg of 1.08 from
300 to 380 K, demonstrating mismatch-driven defect engineering through the β–α
phase transition as a route for optimizing Ag2Se-based thermoelectrics.

text: Ginseng (Panax ginseng) derives its renowned therapeutic properties from ginsenoside
metabolites. However, the long cultivation cycle and susceptibility to diseases
hinder the advancement of the ginseng industry. Here, we demonstrate that the
embryonic protoderm of ginseng can efficiently produce ginsenosides. Single-cell
transcriptome and mass spectrometry imaging analyses reveal that ginsenosides
accumulate in the protoderm of ginseng embryonic callus (EC) at levels comparable
to those in forest ginseng. Epigenetic analyses indicate that elevated histone
acetylation and enhanced chromatin accessibility at regeneration- and ginsenoside
metabolism-related gene loci are associated with the ginsenoside-producing capacity
of EC. Increasing histone acetylation levels or overexpressing the regeneration-related
WUSCHEL-RELATED HOMEOBOX11 (WOX11) gene further enhances ginsenoside production
in EC. Our findings suggest that the protoderm of EC could serve as an in situ
biological compartment for high-efficiency ginsenoside producion, offering a complementary
approach to traditional ginseng cultivation.

text: Alkali salts are widely used in solution processing, yet the corresponding
cations are often assumed to remain in the liquid phase. Here, we show that alkali
ions introduced during the solution synthesis of SnSe are retained through particle
isolation and continue to influence the material during subsequent thermal processing,
where they shape the evolution of the final polycrystalline material. Different
SnSe powders were prepared using Li+, Na+, and K+ precursors, as well as tetramethylammonium
(TMA+) precursors as a nonalkali reference for comparison, and all samples were
consolidated under identical conditions. Although all three alkali ions were found
in the matrix, at grain boundaries, and in segregated nanoscale regions, they
partitioned differently and resulted in distinct grain sizes, defect distributions,
and therefore transport properties. Li induced the strongest grain size heterogeneity
and the lowest energy barriers, Na the best overall balance between carrier concentration
and mobility, and K the broadest alkali-rich grain boundary regions along with
the strongest interfacial penalty to charge carrier transport. These results show
that residual alkali ions are not just remnants of solution synthesis but active
determinants of microstructure and thermoelectric performance in SnSe.

text: Ternary liquid-like thermoelectric materials have garnered significant attention
due to their ultra-low lattice thermal conductivity. Among these, Ag8SnSe6 stands
out for its exceptionally low sound velocity and thermal conductivity. However,
the inherent poor electrical conductivity and suboptimal thermoelectric properties
of Ag8SnSe6 necessitate further improvement. Here, a novel approach is initiated
to enhance the thermoelectric properties of Ag8SnSe6 by combining low-dimensionalization
with intrinsic doping. For the first time, this work successfully synthesizes
single-phase Ag8SnSe6 nanocrystals, ≈10 nm in size, with the correct phase and
composition using a robust and reliable colloidal method. This approach represents
a significant improvement over previous reports on this material. Reducing the
crystal domains of Ag8SnSe6 to the nanoscale induces quantum confinement effects,
increasing the density of states near the Fermi surface. It also introduces additional
grain boundaries, which lower the lattice thermal conductivity and simplify structural
design. Moreover, incorporating small amounts of Sn nanopowder into the Ag8SnSe6
nanocrystals before consolidation further enhances the thermoelectric performance.
Sn acts as a donor dopant, increasing the electronic concentration while at the
same time improving their mobility by reducing interface barriers, thus significantly
improving the material transport properties. Additionally, the presence of Sn
leads to the formation of point defects, dislocations, and secondary phases, which
increase phonon scattering and further reduce the thermal conductivity. Through
this synergistic optimization, the figure of merit shows a significant increase
across a wide temperature range. Overall, a strategy is presented for the controlled
preparation of Ag8SnSe6 nanocrystals, the decoupling of their electrical and thermal
transport, and the practical application of this material to thermoelectric single-leg
modules.

text: SnTe has attracted significant research interest as a lead-free alternative
to PbTe; however, its intrinsically high hole concentration results in an undesirably
low Seebeck coefficient and elevated electronic thermal conductivity, thus significantly
limiting its thermoelectric (TE) performance. Herein, we present a cost-effective,
binary thiol-amine-mediated colloidal synthesis method to synthesize Bi-doped
SnTe nanoparticles, eliminating the use of tri-n-octylphosphine-based precursors.
The introduction of an electron-rich Bi dopant reduces the hole concentration
and increases the Seebeck coefficient. Furthermore, post-synthetic surface treatment
with chalcogenidocadmate complexes promotes atomic interdiffusion during annealing
and consolidation, leading to compositional redistribution and modulation of the
electronic band structure. Density functional theory (DFT) calculations reveal
that co-modification via Bi doping and CdSe-derived chalcogen incorporation reduces
the energy offset at the valence band maxima from 0.30 eV to 0.10 eV, thereby
enhancing valence band degeneracy. The synergistic structural and electronic band
structure modulations produce an SnTe-based material with a record high power
factor of 2.1 mW m–1 K–2 at 900 K, a maximum TE figure of merit (zT) of 1.2, and
a promising theoretical conversion efficiency of 8.3%. This study reports a versatile
and scalable colloidal synthesis strategy that integrates hierarchical structural
modulation with electronic band engineering, offering a synergistic route to significantly
enhance the TE performance.

text: Ag2Se is a promising n-type thermoelectric material, but its performance is
limited by excessive carrier concentration, compositional inhomogeneity, and phase
instability, challenges rooted in a narrow homogeneity range and uncontrolled
Ag+ diffusion in the superionic phase. Here, we address these issues by exploiting
liquid–solid interface reactions using CdSe complexes that remove surface excess
Ag to yield stoichiometric Ag2Se and generate CdSe nanodomains that inhibit Ag+
diffusion and constrain grain growth. The resulting Ag2Se-CdSe nanocomposites
exhibit a reproducible, stable figure of merit (zT) of 1.04 between 300 and 390
K. Beyond demonstrating high performance, we elucidate the interfacial chemical
reactions that give rise to the observed microstructure and transport properties,
providing a foundation for rationally engineering interfacial chemistry to tailor
transport properties across diverse thermoelectric material systems.

text: Lead Sulfide (PbS) has garnered attention as a promising thermoelectric (TE)
material due to its natural abundance and cost-effectiveness. However, its practical
application is hindered by inherently high lattice thermal conductivity and low
electrical conductivity. In this study, we address these challenges by surface
functionalization of PbS nanocrystals using Cu2S molecular complexes-based ligand
displacement. The molecular complexes facilitate the incorporation of Cu into
the PbS matrix and leads to the formation of nanoscale defects, dislocations,
and strain fields while optimizing the charge carrier transport. The structural
modulations enhance the phonon scattering and lead to a significant reduction
in lattice thermal conductivity of 0.60 W m−1K−1 at 867 K in the PbS-Cu2S system.
Simultaneously, the Cu incorporation improves electrical conductivity by increasing
both carrier concentration and mobility with carefully optimized the content of
Cu2S molecular complexes. These synergistic modifications yield a peak figure-of-merit
(zT) of 1.05 at 867 K for the PbS-1.0 %Cu2S sample, representing an almost twofold
enhancement in TE performance compared to pristine PbS. This work highlights the
effectiveness of surface treatment in overcoming the intrinsic limitations of
PbS-based materials and presents a promising strategy for the development of high-efficiency
TE systems.

text: 'In recent years, solution processes have gained considerable traction as
a cost-effective and scalable method to produce high-performance thermoelectric
materials. The process entails a series of critical steps: synthesis, purification,
thermal treatments, and consolidation, each playing a pivotal role in determining
performance, stability, and reproducibility. We have noticed a need for more comprehensive
details for each of the described steps in most published works. Recognizing the
significance of detailed synthetic protocols, we describe here the approach used
to synthesize and characterize one of the highest-performing polycrystalline p-type
SnSe. In particular, we report the synthesis of SnSe particles in water and the
subsequent surface treatment with CdSe molecular complexes that yields CdSe-SnSe
nanocomposites upon consolidation. Moreover, the surface treatment inhibits grain
growth through Zenner pinning of secondary phase CdSe nanoparticles and enhances
defect formation at different length scales. The enhanced complexity in the CdSe-SnSe
nanocomposite microstructure with respect to SnSe promotes phonon scattering and
thereby significantly reduces the thermal conductivity. Such surface engineering
provides opportunities in solution processing for introducing and controlling
defects, making it possible to optimize the transport properties and attain a
high thermoelectric figure of merit.'

text: Production of thermoelectric materials from solution-processed particles involves
the synthesis of particles, their purification and densification into pelletized
material. Chemical changes that occur during each one of these steps render them
performance determining. Particularly the purification steps, bypassed in conventional
solid-state synthesis, are the cause for large discrepancies among similar solution-processed
materials. In present work, the investigation focuses on a water-based surfactant
free solution synthesis of SnSe, a highly relevant thermoelectric material. We
show and rationalize that the number of leaching steps, purification solvent,
annealing, and annealing atmosphere have significant influence on the Sn : Se
ratio and impurity content in the powder. Such compositional changes that are
undetectable by conventional characterization techniques lead to distinct consolidated
materials with different types and concentration of defects. Additionally, the
profound effect on their transport properties is demonstrated. We emphasize that
understanding the chemistry and identifying key chemical species and their role
throughout the process is paramount for optimizing material performance. Furthermore,
we aim to demonstrate the necessity of comprehensive reporting of these steps
as a standard practice to ensure material reproducibility.

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: 'There is a growing interest in cost-effective polycrystalline SnSe-based
thermoelectric (TE) materials, which are able to replace the high performance
but mechanically fragile and costly single-crystalline SnSe. In this study, we
present a low-temperature solution-based approach to produce SnSe-PbSe nanocomposites
with outstanding TE performance. Our method involves combining surfactant-free
SnSe particles with oleate-capped PbSe nanocrystals in specific ratios, followed
by thermal annealing and consolidation using spark plasma sintering. These nanocomposites
are characterized by distinct compositional and structural properties that significantly
impact their transport properties. In particular, the addition of oleate-capped
PbSe nanocrystals results in: i) a reduction in the electrostatically adsorbed
Na at the surface of the SnSe particles; ii) a reduction of Sn vacancies due to
alloying with Pb; iii) an increase in grain boundary density; and iv) the formation
of PbSnSe secondary phases. Notably, the SnSe-2.5 %PbSe nanocomposites demonstrate
a 30 % decrease in thermal conductivity compared to that of the SnSe matrix. This
reduction contributes to a maximum figure of merit (zT) of 1.75 at 788 K with
a high average zT value of ca. 1.2 in the medium temperature range of 573–773
K. These values represent one of the highest reported in polycrystalline SnSe
materials, showcasing the potential of our fabricated SnSe-PbSe nanocomposites
for cost-effective TE applications.'

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: 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: 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: 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: '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: 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: 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. '
