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: 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: "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: 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: 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: '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: '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: 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.
