Achieving the direct growth of an ultrathin gate insulator with high uniformity and high quality on monolayer transition metal dichalcogenides (TMDCs) remains a challenge due to the chemically inert surface of TMDCs. Although the main solution for this challenge is utilizing buffer layers before oxide is deposited on the atomic layer, this method drastically degrades the total capacitance of the gate...
Single atoms are superior electrocatalysts having high atomic utilization and amazing activity for water oxidation and splitting. Herein, this work reports a thermal reduction method to introduce high‐valence iridium (Ir) single atoms into bimetal phosphide (FeNiP) nanoparticles toward high‐efficiency oxygen evolution reaction (OER) and overall water splitting. The presence of high‐valence single...
Aqueous zinc ion batteries (AZIBs) have attracted much interest in the next generation of energy storage devices because of their elevated safety and inexpensive price. Polyanionic materials have been considered as underlying cathodes owing to the high voltage, large ionic channels and fast ionic kinetics. However, the low electronic conductivity limits their cycling stability and rate performance...
The nano‐enabled crop protecting agents have been emerging as a cost‐effective, eco‐friendly, and sustainable alternative to conventional chemical pesticides. Here, the antibacterial activity and disease‐suppressive potential of biogenic copper nanoparticles (bio‐CuNPs) against bacterial fruit blotch (BFB), caused by Acidovorax citrulli (Ac), in watermelon (Citrullus lanatus L.) is discussed. CuNPs...
Recently, single‐atom catalysts are attracting much attention in sensor field due to their remarkable peroxidase‐ or oxidase‐like activities.

Here, self‐constructed bismuth with “sodiophilic” framework and rapid ion transmission characteristics is employed as...
Defect engineering for vacancies, holes, nano precipitates, dislocations, and strain are efficient means of suppressing lattice thermal conductivity. Multiple microstructural defects are successfully designed in Cu1‐xAgxGaTe2 (0 ≤ x ≤ 0.5) solid solutions through high‐ratio alloying and vibratory ball milling, to achieve ultra‐low thermal conductivity and record‐breaking thermoelectric performance...
Manipulating the separation and transfer behaviors of charges has long been pursued for promoting the photoelectrochemical (PEC) hydrogen generation based on II–VI quantum dot (QDs), but remains challenging due to the lack of effective strategies. Herein, a facile strategy is reported to regulate the recombination and transfer of interfacial charges through tuning the surface stoichiometry of heterostructured...
A pseudo‐capacitor with transient behavior is applied in implantable, disposable, and bioresorbable devices, incorporating an Na ion‐doped bioderived ionic liquid, molybdenum trioxide (MoO3)‐covered molybdenum foil, and silk sheet as the electrolyte, electrode, and separator, respectively. Sodium lactate is dissolved in choline lactate as a source of Na ions. The Experimental results reveal that the...
In consideration of high specific capacity and low redox potential, lithium metal anodes have attracted extensive attention. However, the cycling performance of lithium metal batteries generally deteriorates significantly under the stringent conditions of high temperature due to inferior heat tolerance of the solid electrolyte interphase (SEI). Herein, controllable SEI nanostructures with excellent...
