text: Cobalt spinel (Co3O4) catalysts are widely studied in scope of the electrocatalytic
oxygen evolution reaction (OER), yet the role of interfacial structural transformation
under anodic bias remains under debate. Here, we employ an operando approach,
combining a fast electrochemical quartz crystal microbalance with dissipation
monitoring (EQCM-D), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy
to investigate interfacial transformations of Co3O4 nanoparticle electrodes in
alkaline electrolyte. We identify two distinct regimes during the anodic sweep
prior to the macroscopic OER onset. At lower potentials, the catalyst interface
remains mechanically rigid while reversibly associating several OH−/H2O species
per oxidized cobalt site. At higher potentials, pronounced softening of the interface
occurs alongside further uptake of electrolyte species. This indicates amorphization
and a ‘swelling process’ beyond simple adsorption. Notably, an electrochemical
conditioning treatment can suppress mass and compliance hysteresis without affecting
OER activity, suggesting that most incorporated electrolyte species do not participate
in the OER. EIS further reveals that OER intermediates form well below the apparent
OER onset potential. These results advance our mechanistic understanding of interfacial
transformations in cobalt-based OER catalysts and establish EQCM-D as a sensitive
operando technique for probing electrocatalyst transformations.

text: Light-emitting diodes (LEDs) are becoming increasingly important across various
sectors of the lighting industry and are being used more frequently. In the field
of symbolic projection, research is increasingly focusing on implementing light
modulation using energy-efficient, incoherent LEDs rather than lasers. Since light
modulation in micro- and nano-optics is typically achieved through phase modulation,
Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The
objective of this article is to investigate different approaches for approximating
incoherent monochromatic light sources within FDTD simulations. To this end, two
approaches based on dipole sources are considered, as well as a method involving
plane waves with modulated wavefronts based on Cosine–Fourier functions and a
method based on the superposition of Gaussian beams. These methods are evaluated
in terms of their accuracy using a two-dimensional double-slit configuration and
are compared against a fully incoherent analytical reference.

Abstract
The relationship between leptin levels and psychiatric disorders has been studied more extensively in adults than in children and adolescents. However, the results are conflicting. We investigated serum leptin levels in children and adolescents (11 to 18.9 years) with psychiatric disorders (
n
= 363). Absolute and relative (body-mass-index (BMI)-, sex- and pubertal-stage-adjusted z-scores using reference values of healthy children and adolescents) leptin levels of different patient groups according to diagnosis were compared. The association between leptin levels and depression (Beck Depression Inventory-II) and anxiety (Child Behavior Checklist and Youth Self Report) was examined using regression analysis. Leptin z-scores were higher in patients with psychiatric disorders than in healthy controls (median 1.50,
p
< .001). While global tests suggested differences in leptin z-scores between patients with different psychiatric disorders, these differences could not be attributed to diagnosis groups in post-hoc pairwise comparisons. Absolute leptin levels differed between psychiatric disorders (
p
< .001). Patients with anorexia nervosa (AN) had the lowest levels, and patients with mood disorders had higher leptin levels than patients with mental disorders other than mood disorders, anxiety or AN. Neither absolute nor relative leptin levels were related to depressive or anxiety symptoms in regression models adjusted for sex and BMI. Significantly elevated BMI-, sex- and puberty-stage-adjusted leptin levels were observed in children and adolescents with psychiatric disorders compared to a reference sample. Further controlled studies are needed to confirm and explain this finding. No relationship was found between absolute or relative leptin levels and symptoms of depression or anxiety.

text: Proton exchange membranes (PEMs) are essential for fuel cells, yet conventional
materials like Nafion suffer from humidity dependence and limited thermal stability.
This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas
(PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating
with varying alkyl chain lengths for different mesopore sizes. Post-synthetic
functionalization involves nitration of phenylene moieties, reduction to amines,
and ring-opening of propane or butane sultones to graft sulfonic acid groups via
flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization
is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal
p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms
with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization
degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities
up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization
degree, confirming sulfonic acid-mediated conduction.

text: Overcoming the slow kinetics of the oxygen evolution reaction at the anode
is a key challenge for the production of hydrogen via electrolysis. This reaction
operates at very positive potentials, where the electrocatalyst is exposed to
highly oxidative conditions and prone to potential-dependent transformation of
the near-surface region. While substantial evidence for such surface restructuring
exists, its extent and relevance for the catalyst’s activity are unclear. We address
this topic for the case of Co3O4, one of the best-known electrocatalysts exhibiting
surface restructuring, by studies of epitaxial (111)-ordered electrodeposited
films with combined operando X-ray surface diffraction and absorption spectroscopy,
electrochemical impedance spectroscopy, and electrochemical measurements on rotating
disk electrodes. Comparison of the as-prepared and annealed state of the same
samples, which both are stable even under long-term oxygen evolution conditions,
provides clear insight into the role of surface defects. Our results show that
defect-free annealed Co3O4(111) surfaces are structurally stable over a wide potential
range and hydroxylate via adsorption at surface oxygen and Co sites. Potential-induced
surface restructuring of the Co3O4 lattice occurs only in the presence of surface
defects, leading to the formation of the well-known nanometer-thick oxyhydroxide
skin layer. The presence of this skin layer promotes oxygen evolution at low overpotentials
but results in higher Tafel slopes. As a result, highly ordered Co3O4(111) surfaces
are more active at high current densities than defective Co3O4 surfaces that undergo
surface restructuring. These results highlight that strategies for catalyst surface
defect engineering need to be application-oriented.

text: This study investigated whether external effort mobilization through try-harder
instructions enhances performance in complex motor tasks, as reflected by the
reduction of costs associated with producing a deceptive action. Basketball passing
movements with and without head fakes were examined in a reaction-time paradigm.
Participants were generally instructed to initiate the movement as fast and accurately
as possible, while try-harder instructions were presented in 25 % of trials, prompting
participants to mobilize all their cognitive resources to perform even faster.
To investigate if athletic expertise modulates the potential effects of effort
mobilization, basketball novices and experienced players were tested. Results
demonstrated that try-harder instructions generally improved participants’ performance,
facilitating faster response initiation times and movement execution, as well
as a specific reduction in initiation time variability. Novices benefited more
than experienced players, indicating that effort results in greater improvement
when complex motor actions (for example, passes with head fakes) are not yet fully
stabilized and lack automated fluency. This pattern suggests that effort enhances
performance in complex actions when performance is limited by the amount of cognitive
capacity available, supporting the coordination of partly conflicting movement
components within tight temporal constraints. The findings extend previous research
on effort mobilization from simple to complex motor tasks. Try-harder instructions
appear to enhance performance primarily by reducing attentional lapses rather
than generally improving processing speed. Future research should investigate
the effectiveness of effort mobilization in experienced athletes in situations
of high concurrent cognitive load.

text: Probing novel properties, arising from twisted interfaces, has traditionally
relied on the stacking of exfoliated two-dimensional materials and the spontaneous
formation of van der Waals bonds. So far, investigations involving intimate covalent
or ionic bonds have not been a focus. Yet, we show here that an established technique,
involving thermocompressional wafer bonding, works well for creating twisted non-van
der Waals interfaces. We have successfully bonded z-cut lithium niobate single
crystals to create ferroelectric oxide interfaces with strong polar discontinuities
and have mapped the associated emergent interfacial conductivity. In some instances,
a dramatic change in microstructure occurs, involving local dipolar switching.
A twist-induced collapse in the capability of the system to effec8tively screen
interfacial bound charge is implied. Importantly, this only occurs around specific
moiré twist angles with sparse coincident lattices and associated short-range
aperiodicity. In quasicrystals, aperiodicity is known to induce pseudo-bandgaps
and we suspect a similar phenomenon here.

text: Continuous flow catalysis utilizing gel-bound organocatalysts within a microfluidic
reactor represents a compelling strategy in the realm of organic synthesis. In
this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create
polymer gel dots through the process of photopolymerization that serve as a support
for the catalyst. The resulting gel-bound organocatalysts were assembled within
a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between
various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion
of the product was assessed using 1H NMR spectroscopy as an offline analytical
method over a duration of 8 h. The findings indicated that highly reactive aldehydes
achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts.
Furthermore, these results were juxtaposed with previously published data derived
from alternative synthetic methodologies, revealing that the continuous microfluidic
reactions employing integrated organocatalysts within polymer networks exhibited
significantly higher conversions with reduced reaction times (8 h) at the same
temperature (50 °C). Additionally, the influence of different geometries (round,
triangular, and square) of the gel dots on catalytic activity was investigated,
with round and square gel dots demonstrating slightly superior performance compared
with triangular gel dots, attributed to their increased surface area. Moreover,
an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde
and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained
stable for 5 days before experiencing a slight decline due to product accumulation
on the gel dots.

text: AbstractMetasurface holography offers a powerful approach
for manipulating wavefronts at the nano and micro scale. Extensive research has
been conducted to enhance the multiplexing capacity for diverse wavefronts. However,
the independence of multiplexed channels is fundamentally restricted in techniques
using single‐layer metasurfaces, resulting in unavoidable crosstalk and the need
for post‐filtering of the output wavefronts. Here, a universal wavefront multiplexing
concept is presented based on non‐injective transformation. By employing joint
optimization on two metasurfaces, different channels can be independently designed
without any constraints on the output wavefronts. To validate this approach, ultra‐compact
orbital angular momentum (OAM) sorters are designed. In these experiments, the
output beams from different channels can be independently mapped to 2D positions
with high fineness. In another application of wavefront‐multiplexed holography,
10‐channel multiplexing is experimentally achieved with minimal crosstalk and
without the need for post‐processing. These results demonstrate the independence
between channels enabled by the non‐injective transformation in the method. The
precise wavefront control and high multiplexing capacity underscore its potential
for scalable wavefront manipulation devices.

text: 'Spray-induced gene silencing (SIGS) employing double-stranded RNA (dsRNA)
offers a promising, species-specific approach for protecting crops from insect
pests such as the cabbage stem flea beetle (Psylliodes chrysocephala). However,
the environmental instability of dsRNA presents a major limitation to its field
application. In this study, we evaluate two distinct dsRNA formulation strategies
for improved stability and delivery: a bottom-up approach using chitosan-based
interpolyelectrolyte complexes (IPEC) and a top-down approach employing functionalized
mesoporous silica carriers (SBA-15). Both systems were comprehensively characterized
in terms of size, surface potential, porosity, and release behavior. The results
revealed that IPECs exhibited release kinetics that were approximately one order
of magnitude faster than those of SBA-15 across all tested conditions. The two
formulations significantly improved dsRNA stability against UV and heat exposure
compared to free dsRNA. In feeding assays with P. chrysocephala, both carriers
achieved comparable gene silencing efficacy, though dsRNA@IPEC induced more immediate
effects, while dsRNA@SBA-15 displayed delayed but ultimately stronger reduction
in consumed leaf area, consistent with its slower release kinetics. We demonstrate
that despite structural and mechanistic differences, both delivery platforms effectively
stabilized and delivered dsRNA, and offered distinct advantages depending on application
needs. This work highlights how formulation strategies are key to successful SIGS
and supports the development of robust, field-adaptable formulation technologies
for sustainable pest management.'
