text: Frequency-stable lasers form the back bone of precision measurements in science
and technology. Such lasers typically attain their stability through frequency
locking to reference cavities. State-of-the-art locking performances to date had
been achieved using frequency modulation based methods, complemented with active
drift cancellation systems. We demonstrate an all passive, modulation-free laser-cavity
locking technique (squash locking) that utilizes changes in spatial beam ellipticity
for error signal generation, and a coherent polarization post-selection for noise
resilience. By comparing two identically built proof-of-principle systems, we
show a frequency locking instability of 5×10−7 relative to
the cavity linewidth at 10 s averaging. The results surpass the demonstrated performances
of methods engineered over the last five decades, potentially enabling an advancement
in the precision control of lasers, while creating avenues for bridging the performance
gaps between industrial grade lasers with scientific ones due to the afforded
simplicity and scalability.

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: The epitaxial growth of a strained Ge layer, which is a promising candidate
for the channel material of a hole spin qubit, has been demonstrated on 300 mm
Si wafers using commercially available Si0.3Ge0.7 strain relaxed buffer (SRB)
layers. The assessment of the layer and the interface qualities for a buried strained
Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping
confirmed that the reduction of the growth temperature enables the 2-dimensional
growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless,
dislocations at the top and/or bottom interface of the Ge layer were observed
by means of electron channeling contrast imaging, suggesting the importance of
the careful dislocation assessment. The interface abruptness does not depend on
the selection of the precursor gases, but it is strongly influenced by the growth
temperature which affects the coverage of the surface H-passivation. The mobility
of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010
/cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the
heterostructure thanks to the high Si0.3Ge0.7 SRB quality.

text: Models for same-material contact electrification in granular media often rely
on a local charge-driving parameter whose spatial variations lead to a stochastic
origin for charge exchange. Measuring the charge transfer from individual granular
spheres after contacts with substrates of the same material, we find instead a
“global” charging behavior, coherent over the sample’s whole surface. Cleaning
and baking samples fully resets charging magnitude and direction, which indicates
the underlying global parameter is not intrinsic to the material, but acquired
from its history. Charging behavior is randomly and irreversibly affected by changes
in relative humidity, hinting at a mechanism where adsorbates, in particular,
water, are fundamental to the charge-transfer process.

text: "Nominally identical materials exchange net electric charge during contact
through a mechanism that is still debated. ‘Mosaic models’, in which surfaces
are presumed to consist of a random patchwork of microscopic donor/acceptor sites,
offer an appealing explanation for this phenomenon. However, recent experiments
have shown that global differences persist even between same-material samples,
which the standard mosaic framework does not account for. Here, we expand the
mosaic framework by incorporating global differences in the densities of donor/acceptor
sites. We develop\r\nan analytical model, backed by numerical simulations, that
smoothly connects the global and deterministic charge transfer of different materials
to the local and stochastic mosaic picture normally associated with identical
materials. Going further, we extend our model to explain the effect of contact
asymmetries during sliding, providing a plausible explanation for reversal of
charging sign that has been observed experimentally."

text: A rotating organic cation and a dynamically disordered soft inorganic cage
are the hallmark features of organic-inorganic lead-halide perovskites. Understanding
the interplay between these two subsystems is a challenging problem, but it is
this coupling that is widely conjectured to be responsible for the unique behavior
of photocarriers in these materials. In this work, we use the fact that the polarizability
of the organic cation strongly depends on the ambient electrostatic environment
to put the molecule forward as a sensitive probe of the local crystal fields inside
the lattice cell. We measure the average polarizability of the C/N–H bond stretching
mode by means of infrared spectroscopy, which allows us to deduce the character
of the motion of the cation molecule, find the magnitude of the local crystal
field, and place an estimate on the strength of the hydrogen bond between the
hydrogen and halide atoms. Our results pave the way for understanding electric
fields in lead-halide perovskites using infrared bond spectroscopy.

text: The self-assembly of nanoparticles driven by small molecules or ions may produce
colloidal superlattices with features and properties reminiscent of those of metals
or semiconductors. However, to what extent the properties of such supramolecular
crystals actually resemble those of atomic materials often remains unclear. Here,
we present coarse-grained molecular simulations explicitly demonstrating how a
behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
As a case study, we focus on gold nanoparticles bearing positively charged groups
that self-assemble into FCC crystals via mediation by citrate counterions. In
silico ohmic experiments show how the dynamically diverse behavior of the ions
in different superlattice domains allows the opening of conductive ionic gates
above certain levels of applied electric fields. The observed binary conductive/nonconductive
behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular
level, crossing the “band gap” requires a sufficient electrostatic stimulus to
break the intermolecular interactions and make ions diffuse throughout the superlattice’s
cavities.

text: Catalysis, the acceleration of product formation by a substance that is left
unchanged, typically results from multiple elementary processes, including diffusion
of the reactants toward the catalyst, chemical steps, and release of the products.
While efforts to design catalysts are often focused on accelerating the chemical
reaction on the catalyst, catalysis is a global property of the catalytic cycle
that involves all processes. These are controlled by both intrinsic parameters
such as the composition and shape of the catalyst and extrinsic parameters such
as the concentration of the chemical species at play. We examine here the conditions
that catalysis imposes on the different steps of a reaction cycle and the respective
role of intrinsic and extrinsic parameters of the system on the emergence of catalysis
by using an approach based on first-passage times. We illustrate this approach
for various decompositions of a catalytic cycle into elementary steps, including
non-Markovian decompositions, which are useful when the presence and nature of
intermediate states are a priori unknown. Our examples cover different types of
reactions and clarify the constraints on elementary steps and the impact of species
concentrations on catalysis.

text: Most permissionless blockchains inherently suffer from throughput limitations.
Layer-2 systems, such as side-chains or Rollups, have been proposed as a possible
strategy to overcome this limitation. Layer-2 systems interact with the main-chain
in two ways. First, users can move funds from/to the main-chain to/from the layer-2.
Second, layer-2 systems periodically synchronize with the main-chain to keep some
form of log of their activity on the main-chain - this log is key for security.
Due to this interaction with the main-chain, which is necessary and recurrent,
layer-2 systems impose some load on the main-chain. The impact of such load on
the main-chain has been, so far, poorly understood. In addition to that, layer-2
approaches typically sacrifice decentralization and security in favor of higher
throughput. This paper presents an experimental study that analyzes the current
state of Ethereum layer-2 projects. Our goal is to assess the load they impose
on Ethereum and to understand their scalability potential in the long-run. Our
analysis shows that the impact of any given layer-2 on the main-chain is the result
of both technical aspects (how state is logged on the main-chain) and user behavior
(how often users decide to transfer funds between the layer-2 and the main-chain).
Based on our observations, we infer that without efficient mechanisms that allow
users to transfer funds in a secure and fast manner directly from one layer-2
project to another, current layer-2 systems will not be able to scale Ethereum
effectively, regardless of their technical solutions. Furthermore, from our results,
we conclude that the layer-2 systems that offer similar security guarantees as
Ethereum have limited scalability potential, while approaches that offer better
performance, sacrifice security and lead to an increase in centralization which
runs against the end-goals of permissionless blockchains.

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: Redox flow batteries (RFBs) rely on the development of cheap, highly soluble,
and high-energy-density electrolytes. Several candidate quinones have already
been investigated in the literature as two-electron anolytes or catholytes, benefiting
from fast kinetics, high tunability, and low cost. Here, an investigation of nitrogen-rich
fused heteroaromatic quinones was carried out to explore avenues for electrolyte
development. These quinones were synthesized and screened by using electrochemical
techniques. The most promising candidate, 4,8-dioxo-4,8-dihydrobenzo[1,2-d:4,5-d′]bis([1,2,3]triazole)-1,5-diide
(−0.68 V(SHE)), was tested in both an asymmetric and symmetric full-cell setup
resulting in capacity fade rates of 0.35% per cycle and 0.0124% per cycle, respectively.
In situ ultraviolet-visible spectroscopy (UV–Vis), nuclear magnetic resonance
(NMR), and electron paramagnetic resonance (EPR) spectroscopies were used to investigate
the electrochemical stability of the charged species during operation. UV–Vis
spectroscopy, supported by density functional theory (DFT) modeling, reaffirmed
that the two-step charging mechanism observed during battery operation consisted
of two, single-electron transfers. The radical concentration during battery operation
and the degree of delocalization of the unpaired electron were quantified with
NMR and EPR spectroscopy.

text: 'Motivated by properties-controlling potential of the strain, we investigate
strain dependence of structure, electronic, and magnetic properties of Sr2IrO4
using complementary theoretical tools: ab-initio calculations, analytical approaches
(rigid octahedra picture, Slater-Koster integrals), and extended t−J model. We
find that strain affects both Ir-Ir distance and Ir-O-Ir angle, and the rigid
octahedra picture is not relevant. Second, we find fundamentally different behavior
for compressive and tensile strain. One remarkable feature is the formation of
two subsets of bond- and orbital-dependent carriers, a compass-like model, under
compression. This originates from the strain-induced renormalization of the Ir-O-Ir
superexchange and O on-site energy. We also show that under compressive (tensile)
strain, Fermi surface becomes highly dispersive (relatively flat). Already at
a tensile strain of 1.5%, we observe spectral weight redistribution, with the
low-energy band acquiring almost purely singlet character. These results can be
directly compared with future experiments.'

text: Polydicyclopentadiene (pDCPD), a thermoset with excellent mechanical properties,
has enormous potential as a lightweight, tough, and stable matrix material owing
to its highly cross-linked macromolecular network. This work describes generating
pDCPD-based foams and hierarchically porous carbons derived therefrom by combining
ring-opening metathesis polymerization (ROMP) of DCPD, high internal phase emulsions
(HIPEs) as structural templates, and subsequent carbonization. The structure and
function of the carbon foams were characterized and discussed in detail using
scanning electron, transmission electron, or atomic force microscopy (SEM, TEM,
AFM), electron energy-loss spectroscopy (TEM-EELS), N2 sorption, and analyses
of electrical conductivity as well as mechanical properties. The resulting materials
exhibited uniform, shape-retaining shrinkage of only ∼1/3 after carbonization.
No structural failure was observed even when the pDCPD precursor foams were heated
to 1400 °C. Instead, the high porosity, void size, and 3D interconnectivity were
fully preserved, and the void diameters could be adjusted between 87 and 2.5 μm.
Moreover, foams have a carbon content >97%, an electronic conductivity of up to
2800 S·m–1, a Young’s modulus of up to 2.1 GPa, and a specific surface area of
up to 1200 m2·g–1. Surprisingly, the pDCPD foams were carbonized into shapes other
than monoliths, such as 10’s of micron thick membranes or foamy coatings adhered
to a metal foil or grid substrate. The latter coatings even adhere upon bending.
Finally, as a use case, carbonized foams were applied as porous cathodes for Li–O2
batteries where the foams show a favorable combination of porosity, active surface
area, and pore size for outstanding capacity.

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 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: Mercury telluride (HgTe) thin films with a critical thickness of 6.5 nm are
predicted to possess a gapless Dirac-like band structure. We report a comprehensive
study on gated and optically doped samples by magnetooptical spectroscopy in the
THz range. The quasi-classical analysis of the cyclotron resonance allowed the
mapping of the band dispersion of Dirac charge carriers in a broad range of electron
and hole doping. A smooth transition through the charge neutrality point between
Dirac holes and electrons was observed. An additional peak coming from a second
type of holes with an almost density-independent mass of around 0.04m0 was detected
in the hole-doping range and attributed to an asymmetric spin splitting of the
Dirac cone. Spectroscopic evidence for disorder-induced band energy fluctuations
could not be detected in present cyclotron resonance experiments.

text: Confining molecules within well-defined nanosized spaces can profoundly alter
their physicochemical characteristics. For example, the controlled aggregation
of chromophores into discrete oligomers has been shown to tune their optical properties
whereas encapsulation of reactive species within molecular hosts can increase
their stability. The resazurin/resorufin pair has been widely used for detecting
redox processes in biological settings; yet, how tight confinement affects the
properties of these two dyes remains to be explored. Here, we show that a flexible
PdII6L4 coordination
cage can efficiently encapsulate both resorufin and resazurin in the form of dimers,
dramatically modulating their optical properties. Furthermore, binding within
the cage significantly decreases the reduction rate of resazurin to resorufin,
and the rate of the subsequent reduction of resorufin to dihydroresorufin. During
our studies, we also found that upon dilution, the PdII6L4
cage disassembles to afford PdII2L2
species, which lacks the ability to form inclusion complexes – a process that
can be reversed upon the addition of the strongly binding resorufin/resazurin
guests. We expect that the herein disclosed ability of a water-soluble cage to
reversibly modulate the optical and chemical properties of a molecular redox probe
will expand the versatility of synthetic fluorescent probes in biologically relevant
environments.

text: Confinement within molecular cages can dramatically modify the physicochemical
properties of the encapsulated guest molecules, but such host-guest complexes
have mainly been studied in a static context. Combining confinement effects with
fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
systems—and ultimately materials—whose desired properties could be tailored “on
demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
inclusion complexes of an open-window coordination cage that can simultaneously
accommodate two guest molecules. Working with two types of guests, anthracene
derivatives and BODIPY dyes, we show that the former can substantially modify
the optical properties of the latter upon noncovalent heterodimer formation. We
also studied the light-induced covalent dimerization of encapsulated anthracenes
and found large effects of confinement on reaction rates. By coupling the photodimerization
with the rapid guest exchange, we developed a new way to modulate fluorescence
using external irradiation.
