text: Copper chalcogenides offer high charge mobility and low lattice thermal conductivity
but suffer from structural instability due to dynamic Cu+ migration. Here, we
report a colloidal hot-injection synthesis of ternary cesium copper selenide (CsCu5Se3)
nanocrystals (NCs), achieving precise control over phase, size, and morphology
through tailored precursor-ligand modulation. This strategy enabled systematic
exploration of stable and metastable Cs–Cu–Se phases and mechanistic investigation
of nucleation and growth, providing insight into phase modulation and dimensional
control at the nanoscale. CsCu5Se3 NCs exhibit low lattice thermal conductivity
(∼0.5 Wm–1K–1) and an experimental zT of 0.27 at 718 K. Complementary first-principles
calculations, consistent with experimental electronic and optical responses, predict
a zT of 1.05 at 1000 K. These findings elucidate the formation dynamics of CsCu5Se3
and establish ABZ (A = alkali, B = metal, Z = chalcogen) NCs as tunable platforms
for advanced functional applications.

text: Liquid-like superionic conductors, with highly mobile ions in a rigid framework,
offer intrinsically low lattice thermal conductivity without compromising electronic
transport. Argyrodite-type Ag8SnSe6 exhibits a melt-like Ag sublattice that drives
lattice thermal conductivity (κL) below 0.2 watts per meter per kelvin, yet its
low carrier concentration limits the power factor. Here, interstitial Ag atoms
raise the Fermi level into the conduction band, substantially increasing the electron
concentration. Simultaneously, the formation of a secondary Ag2Se phase generates
lattice distortions that enhance phonon scattering. A pronounced mismatch between
electronic (~200 nanometers) and phononic (~0.22 nanometers) mean free paths decouples
charge and heat transport, enabling concurrent suppression of κL and retention
of high electrical conductivity. This coupled electronic-phononic modulation yields
a record ZT of 0.72 at ambient temperature and a peak ZT of 1.1 at 735 kelvins,
with an average ZTavg of 0.72 over 320 to 735 kelvins. A unicouple device achieves
6.3% efficiency under a 357-kelvin gradient, highlighting a practical strategy
for high-performance midtemperature thermoelectrics.

text: Redox-mediated flow batteries boost energy density by utilizing dissolved
redox species as charge carriers for solid charge-storage materials. This strategy
strongly depends on the thermodynamics and kinetics between the solid booster
and dissolved redox species. Conventional electrochemical methods often convolute
intrinsic reactivity with mass transport effects, introducing complexity in determining
limiting steps. We propose a strategy that confines solid boosters within recessed
microelectrodes and employs scanning electrochemical microscopy (SECM) to estimate
reaction kinetics between booster and dissolved active redox species. Confining
the solid booster in the recessed microelectrode overcomes mass transport limitations
of dissolved redox species and enables controlled polarization of the booster
material, allowing deconvolution of key rate-determining factors. As an initial
model system, Prussian blue-ferricyanide/ferrocyanide [Fe(CN)6]3−/4− was used
as solid booster and dissolved redox active species, respectively. The methodology
was further explored for copper hexacyanoferrate with N,N,N-2,2,6,6-heptamethylpiperidinyl
oxy-4-ammonium chloride and nickel hydroxide with [Fe(CN)6]3−/4− and extended
to Mn-based Prussian blue analogues in combination with organic redox species.
Our results demonstrate that SECM coupled with the proposed recessed microelectrode
strategy provides a powerful platform to disentangle interfacial kinetics and
guide the rational design of solid booster-dissolved redox species and electrolytes
for high-performance redox-mediated flow batteries.

text: High-voltage disordered spinel LiNi0.5Mn1.5O4 is a promising cathode material
for high power density in lithium-ion batteries. However, it suffers from poor
cycle life associated with the rock-salt phase transformation. This study presents
a straightforward synthesis approach to enhance the electrochemical performance
of LiNi0.5Mn1.5O4 through a synergistic solid-state modification with LiF and
AlF3. This dual modification promotes rapid Li⁺ diffusion, enables near-complete
delithiation/lithiation, approaching the theoretical capacity of disordered LiNi0.5Mn1.5O4,
and, more importantly, effectively mitigates the formation of the rock-salt phase,
thereby enhancing structural stability, as confirmed by operando X-ray absorption
spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the
optimized LiNi0.5Mn1.5O4 (10 mg AlF3 + 30 mg LiF) delivers high reversible capacities
of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g−1 at 0.2C, 0.5C, 1.0C,
2.0C, 3.0C, 4.0C, and 5.0C, respectively. Full cells using graphite as the anode
and a high-loading cathode exhibit excellent cycling performance. They retain
80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5–4.9
V with cathode loading of 11 mg∙cm−2. The findings of this study will significantly
advance high-power LiNi0.5Mn1.5O4 materials, offering improved battery life and
thereby enhancing their potential for practical applications.

text: CuAgSe-based materials are attractive for low-temperature thermoelectric (TE)
applications but are limited by bipolar conduction and relatively high thermal
conductivity. Herein, we report a ligand-free aqueous synthesis of Te-doped CuAgSe
(CuAgSe1-xTex), where structural and electronic modulation improve carrier transport
and suppress phonon propagation. Ex-situ time-resolved X-ray diffraction reveals
a spontaneous growth mechanism, while density functional theory calculations show
that Te-5s and 5p orbitals hybridization generates localized states and an asymmetric
density of states, thereby enhancing the Seebeck coefficient. Electron microscopy
and strain analyses confirm that Te-doping introduces a high density of lattice
dislocations and grain boundaries, leading to a reduced lattice thermal conductivity
of 0.11 W m−1K−1 at 443 K. These synergistic effects translate into device-level
performance—the first integrated CuAgSe thermoelectric modules, exhibit a maximum
cooling temperature difference of 27.3 K, and power density of 0.34 W cm−2 with
a conversion efficiency of 3.6% at a modest temperature gradient of 136 K. These
results demonstrate that CuAgSe1-xTex enables efficient energy harvesting and
localized cooling under small temperature gradient, underscoring the importance
of structural and electronic design beyond conventional zT benchmarks.

text: High-entropy alloys (HEAs) show great potential for catalyzing complex multi-step
reactions, but optimizing their parameters, i.e., composition, but also their
crystallinity and morphology, remains a significant challenge. In this study,
FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline
nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S)
reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells,
and pouch cells reveal that HEANS significantly enhance LSB performance, achieving
initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent
cycling stability over 1000 cycles at 3Cand maintain high-rate performance up
to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density
functional theory calculations demonstrate that amorphous HEANS provide more active
sites, better ionic conductivity and stronger chemical interactions with lithium
polysulfides (LiPS). These properties effectively suppress the shuttle effect,
promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte
interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy
barrier. Overall, this study highlights the superior catalytic properties of amorphous
2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion.

text: The oxygen reduction reaction (ORR) remains a critical bottleneck in fuel
cells and metal-air batteries due to the lack of highly efficient electrocatalysts.
Here, we report a simple strategy for synthesizing a palladium-based heterostructured
electrocatalyst supported on a carbon nitride matrix (PdH-Pd@CN), which exhibits
remarkable ORR activity with a half-wave potential of 0.91 V and excellent durability
in 0.1 M KOH. Within the heterostructure, hydrogen intercalation expands the Pd
lattice, while interstitial hydrogen doping facilitates charge transfer from Pd
to H owing to their electronegativity difference. These synergistic effects modulate
the electronic structure, thereby enhancing both activity and stability. When
employed in Zn-air batteries, PdH-Pd@CN delivers a maximum power density of 176
mW cm− (Liu et al., 2025) and capacity of 805 mAh g− (Sun et al., 2021) Zn. These
findings demonstrate the strong potential of PdH-Pd@CN as an efficient ORR electrocatalyst
for next-generation metal-air batteries and related energy technologies.

text: Nanocrystal superlattices are commonly formed by changing concentration, solvent
conditions, or particle surface chemistry. Although effective, these approaches
alter multiple contributions to the interparticle potential simultaneously, making
it difficult to isolate the interactions responsible for ordering or to control
assembly in chemically complex environments. Here, we show that oligomeric species
present in a nanocrystal reaction medium drive superlattice formation through
a depletion mechanism. Using PbTe nanocrystals as a model system, we identify
Pb–oleate oligomers in the crude reaction mixture, characterize their solution
structure, and quantify their contribution to the interparticle potential, establishing
depletion as the dominant short-range interaction governing spontaneous body-centered
cubic superlattice formation. We then confirm the depletion origin of ordering
by showing that varying depletant concentration predictably shifts the order–disorder
boundary and produces a thermally reversible transition between dispersed and
ordered states ─ behavior that is inconsistent with van der Waals or ligand-mediated
mechanisms but is a direct consequence of depletion control. Having established
and validated the mechanism, we demonstrate that the same depletion framework
can be deliberately activated in purified dispersions and transferred across nanocrystal
systems of different composition and shape, including anisotropic and binary assemblies.
These results establish precursor-derived depletion as a general and chemically
grounded mechanism for nanocrystal superlattice formation, and show that collective
ordering can be programmed through the surrounding medium rather than through
particle surface modification.

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: 'The development of cost-effective and high-performance thermoelectric (TE)
materials faces significant challenges, particularly in improving the properties
of promising copper-based TE materials such as Cu3SbSe4, which are limited by
their poor electrical conductivity. This study presents a detailed comparative
analysis of three strategies to promote the electrical transport properties of
Cu3SbSe4 through Sn doping: conventional Sn atomic doping, surface treatment with
SnSe molecular complexes, and blending with SnSe nanocrystals to form nanocomposites,
all followed by annealing and hot pressing under identical conditions. Our results
reveal that a surface treatment using SnSe molecular complexes significantly enhances
TE performance over atomic doping and nanocomposite formation, achieving a power
factor of 1.1 mW·m−1·K−2 and a maximum dimensionless figure of merit zT value
of 0.80 at 640 K, representing an excellent performance among Cu3SbSe4-based materials
produced via solution-processing methods. This work highlights the effectiveness
of surface engineering in optimizing the transport properties of nanostructured
materials, demonstrating the versatility and cost-efficiency of solution-based
technologies in the development of advanced nanostructured materials for application
in the field of TE among others.'

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: Electrolyte additives are extensively validated effective in mitigating dendrite
growth and parasitic reactions in aqueous zinc-ion batteries (AZIBs). Nonetheless,
the mechanisms by which additives influence the formation and characteristics
of the inorganic solid–electrolyte interphase (SEI) are not yet fully elucidated.
Herein, we investigate how Zn(CF3COO)2 additives influence solvation structure
and elucidate the mechanism by which these additives promote the dual reduction
of anions. Through cryo-transmission electron microscopy analysis, we identified
the SEI as a highly amorphous ZnS/ZnF2 phase. This amorphous hybrid SEI demonstrates
exceptional stability, mechanical robustness, and high Zn2+ conductivity, effectively
mitigating parasitic reactions and enhancing Zn plating/stripping reversibility.
Even under elevated current densities, the Zn anode exhibits ultra-stable longevity
and ultra-high reversibility. This study provides a comprehensive understanding
of the intrinsic mechanisms governing solvation structure modulation that lead
to the formation of amorphous hybrid SEI, underscoring their efficacy in enhancing
the performance and durability of AZIBs.

text: The determination of the intrinsic properties of solid active material candidates
is essential for their performance optimization. However, macroscopic electrodes
and related analytical techniques show challenges concerning the number of additional
influencing parameters. We explore recessed microelectrodes (rME) as a platform
that allows for a binder-free investigation of Prussian Blue analogues (PBA),
a family of promising battery materials. The enhanced diffusion using microelectrochemical
tools is indispensable to assess the intrinsic material performance, overcoming
the limitation of cation diffusion from the electrolyte to the solid interface
during (dis)charging cycles and allowing the investigation of limiting steps in
the coupled ion-electron transfer process. The intrinsic electrochemical performance
of PBAs was studied in a three-electrode configuration by means of cyclic voltammetry
and galvanostatic (dis)charging in aqueous Na+-containing electrolyte. We extended
the evaluation to the role of the electrolyte on the performance of cathodic and
anodic processes of a Mn-based PBA. Ex-situ and operando chemical characterization
were coupled to support the microelectrochemical results.

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: We present a novel, portable sensor platform that enables concurrent monitoring
of surface mass and charge density variations at thin biointerfaces. This platform
combines a coplanar-gated field-effect transistor (FET) architecture with grating-coupled
surface plasmon resonance (SPR), yielding an integrated disposable sensor chip
prepared by nanoimprint and maskless photolithography techniques. The sensor chip
design is suitable for scalable production and relies on reduced graphene oxide
(rGO), serving as the FET’s semiconductor material for the electronic readout,
and a metallic gate electrode surface that is corrugated with a multi-diffractive
structure for optical probing with resonantly excited surface plasmons. Together
with its integration in a compact instrumentation this results in a form factor
optimized solution for dual-mode investigations without compromising the optical
or electronic sensor performance. A poly-L-lysine (PLL) – based thin linker layer
was deployed at the sensor surface to covalently attach azide-conjugated biomolecules
by using incorporated “clickable” dibenzocyclooctyne (DBCO) moieties. Interestingly,
the dual-mode measurements allow elucidating the role of the globular nature of
the PLL chains when increasing the density of DBCO attached to their backbone,
leading to PLL folding and internalization of DBCO moieties, and thus reducing
the coupling yield for the used DNA oligomers. We envision that this platform
can be employed to studying a range of other biointerface architectures and biomolecular
interaction phenomena, which are inherently tied to mass and charge density variations.

text: Thermoelectric coolers (TECs) are pivotal in modern heat management but face
limitations in efficiency and manufacturing scalability. We address these challenges
by using an extrusion-based 3D printing technique to fabricate high-performance
thermoelectric materials. Our ink formulations ensure the integrity of the 3D-printed
structure and effective particle bonding during sintering, achieving record-high
figure of merit (zT) values of 1.42 for p-type bismuth antimony telluride [(Bi,Sb)2Te3]
and 1.3 for n-type silver selenide (Ag2Se) materials at room temperature. The
resulting TEC demonstrates a cooling temperature gradient of 50°C in air. Moreover,
this scalable and cost-effective method circumvents energy-intensive and time-consuming
steps, such as ingot preparation and subsequently machining processes, offering
a transformative solution for thermoelectric device production and heralding a
new era of efficient and sustainable thermoelectric technologies.

text: The SiOx anode exhibits a high specific capacity and commendable durability
for lithium-ion batteries (LIBs). However, its practical application is hindered
by significant volumetric fluctuations during lithiation/delithiation, alongside
a metastable nature, which induces mechanical instability and irreversible lithium
consumption, ultimately impairing long-term capacity retention in full-battery
cell configurations. In this study, we present a phase-engineering approach designed
to improve the structural stability of SiOx anodes for LIB applications. By incorporating
lithium fluoride, amorphous SiOx undergoes partial transformation into a quartz-like
phase, which enhances mechanical integrity and mitigates irreversible lithium
loss. This modified anode demonstrates significantly improved stability and prolonged
cycle lifespan. Through a combination of multiscale simulations and in situ characterizations,
we elucidate the stabilization mechanisms conferred by the quartz phase, providing
critical insights into the role of SiOx’s crystal structure in influencing degradation
pathways. This work introduces an accessible and efficient method for controlling
the crystallinity of SiOx, offering a practical solution to enhance the durability
of high-energy-density LIBs.

text: The oxidation of biomass-derived compounds such as glucose within electrochemical
cells enables both the energy-efficient production of hydrogen and the generation
of additional added-value chemicals from biomass. However, for this biomass valorization
approach to become commercially viable, selective, cost-effective, and highly
active electrooxidation catalysts need to be developed. In this work, we detail
the synthesis of a nickel (Ni) and zinc (Zn)-based electrocatalyst for the glucose
oxidation reaction (GOR) to formic acid (FoA) via calcination of a Zn-based zeolitic
imidazole framework (ZIF) functionalized with ethylenediamine and doped with Ni.
The structure, morphology, and electrochemical performance of the catalysts towards
the anodic GOR to FoA coupled with the cathodic hydrogen evolution reaction (HER)
are subsequently studied. Chronopotentiometry tests with 0.1 M of glucose show
a conversion of 94 % at 250 mA in only 70 min, with a Faradaic efficiency (FE)
of 91 % toward the production of FoA. Meanwhile, at the cathode, the HER FE is
close to 98 %.

text: "In an era of high-resolution displays, powerful design software, and automated
plotting tools, one would think that scientific figures would be clearer than
ever. Yet, despite numerous editorials, guidelines, and workshops dedicated to
improving figure design, poorly constructed figures remain a persistent issue.
Editors and experienced researchers have repeatedly highlighted key pitfalls such
as cluttered layouts, inconsistent formatting, poor color choices, and misleading
visuals. (1−8) Yet, the aforementioned graphical shortcomings continue to plague
even high-impact journals. Why? The problem is not a lack of technology; it is
a combination of poor design habits, rushed deadlines, and a tendency to treat
figures as mere “data dumps” rather than as essential storytelling tools.\r\nMany
people process information more effectively through visuals, naturally associating
concepts easily when presented graphically. A well-crafted figure serves as a
narrative within the larger story, making complex ideas more accessible. Unfortunately,
visual storytelling often takes a backseat in scientific communication. Scientists
are trained to analyze and interpret data, but many default to software-generated
plots without considering accessibility or how their figures will be perceived
by readers outside their immediate field. Without thoughtful design, figures lose
their power to enhance understanding, ultimately limiting the significance of
the research itself.\r\nIn this editorial, we examine the challenges that, in
our view, hamper scientific figure design and discuss how thoughtful refinements
driven by feedback, iteration, and design principles can enhance clarity and impact
visual communication."

text: The transverse thermoelectric (Nernst) effect is a powerful probe for studying
the electronic and structural properties of materials. In this study, we employ
transverse thermoelectric measurements to investigate the ferroelectric distortion
in the topological crystalline insulator (TCI) Pb0.60Sn0.40Te, a compound derived
from PbTe and SnTe, known for their exceptional thermoelectric performance and
distinct ferroelectric properties. By leveraging Nernst measurements, we provide
direct evidence of ferroelectric distortion in this TCI, corroborated by Shubnikov–de
Haas quantum oscillations that confirm the presence of two topologically nontrivial
Fermi pockets. Density functional theory calculations show that these pockets
originate from the L and T points in the Brillouin zone of the distorted structure
within the TCI phase. Raman spectroscopy further identifies a structural phase
transition below 50 K, consistent with the quantum oscillation observations. This
observation is further substantiated by temperature-dependent synchrotron X-ray
pair distribution function analysis and transmission electron microscopy, which
confirm the local off-centering of cations at low temperature. These findings
underscore the potential of transverse thermoelectric measurements in unveiling
ferroelectric distortions and their role in modulating topological quantum states,
opening new directions for research into the synergy between ferroelectricity
and topological phases.
