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: 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: 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: 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: 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: 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: 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: 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 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: 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: '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.'
