Rational design of water splitting electrocatalysts through computational insights.

Electrocatalytic water splitting is vital for the sustainable production of green hydrogen. Electrocatalysts, including those for the hydrogen evolution reaction at the cathode and the oxygen evolution reaction at the anode, are crucial in determining the overall performance of water splitting. Traditional methods for electrocatalyst development often rely on trial-and-error, which can be time-consuming and inefficient.

Effect of frozen storage duration on temporal dominance of sensations (TDS), chemical investigations and moisture distribution of roasted chicken wings.

In order to guide manufacturers or consumers to choose frozen chicken wings (CWS) reasonably for roasting, the changes of sensory quality and physicochemical properties of CWS with different freezing storage time (0-12 months) after roasting were studied. The results showed that juiciness, fat flavor, meat flavor, and saltiness were the most important dominant attributes of roasted CWS, and their dominance rate gradually decreased from the ninth month. Increased (P < 0.

Current trends in colorimetric biosensors using nanozymes for detecting biotoxins (bacterial food toxins, mycotoxins, and marine toxins).

Biotoxins, predominantly bacterial food toxins, mycotoxins, and marine toxins, have emerged as major threats in the fields of seafood, other foods, feeds, and medicine. They have potential teratogenic, mutagenic, and carcinogenic effects on humans, occasionally triggering high morbidity and mortality. One of the apparent concerns relates to the increasing consumption of fast food resulting in the demand for processed food without adequate consideration of the toxins they may contain.

Disease burden of esophageal cancer attributable to low fruit intake in China and globally from 1990 to 2019.

Objective: To understand the disease burden of esophageal cancer (EC) attributable to inadequate fruit intake in China and global from 1990 to 2019 stratified by age and sex.

The population attributable fractions (PAF) were applied to estimate the proportion of EC caused by low fruit intake.

High Power Factor Flexible AgTe Film on Nylon by a Wet Chemical Method for Power Generator.

Herein, we develop a facile wet chemical method for the synthesis of AgTe powders at room temperature and flexible AgTe/nylon thermoelectric (TE) films are prepared by vacuum-assisted filtration of the synthesized AgTe powders and then hot pressing. Because of the good crystallinity of AgTe grains and continuous grain boundaries, an optimized film exhibits a power factor of 513 μW m K at 300 K, which stands among the highest values reported for AgTe-based films to date. In addition, the film also has good flexibility.

Controllable Design of Metal-Organic Framework-Derived Vanadium Oxynitride for High-Capacity and Long-Cycle Aqueous Zn-Ion Batteries.

Introducing N atoms in vanadium oxides (VO) of aqueous Zn-ion batteries (ZIBs) can reduce their bandgap energy and enhance their electronic conductivity, thereby promoting the diffusion of Zn. The close-packed vanadium oxynitride (VON) generated often necessitates the intercalation of water molecules for restructuring, rendering it more conducive for zinc ion intercalation. However, its dense structure often causes structural strain and the formation of by-products during this process, resulting in decreased electrochemical performance.

Nano-metal diborides-supported anode catalyst with strongly coupled TaO/IrO catalytic layer for low-iridium-loading proton exchange membrane electrolyzer.

The sluggish kinetics of oxygen evolution reaction (OER) and high iridium loading in catalyst coated membrane (CCM) are the key challenges for practical proton exchange membrane water electrolyzer (PEMWE).

Screening and Understanding Lattice Silicon-Controlled Catalytically Active Site Motifs from a Library of Transition Metal-Silicon Intermetallics.

A joint theoretical and experimental study is reported to systematically explore over a library of transition metal-silicon intermetallics for understanding silicon-controlled active site motifs and discovering hydrogen-evolving electrocatalysts. On the one hand, every low-index surface termination of 115 transition metal (M)-silicon (Si) intermetallics is enumerated, followed by cataloging of stable adsorption sites and prediction of catalytic activities on the main exposed facets. It is theoretically found that silicon atoms in silicon-rich structures (especially MSi and MSi) show a strong site-isolating effect, which can eliminate M-M-M hollow and M-M bridge sites with too strong hydrogen-binding ability and thereby provide great opportunities for the exposure of novel highly active sites (e.
