In article number 2308443, Soorathep Kheawhom, and co‐workers delve into the critical role of lanthanum and strontium perovskite oxides in augmenting the efficiency of zinc‐air batteries, highlighting their cost‐effectiveness and adaptability as electrocatalysts for oxygen‐related reactions. They examine their structures, synthesis, and how they function in oxygen reduction and...
Inspired by the superglue fuming method for fingerprint collection, this study developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. High‐electronegativity groups are introduced on the substrate surface to initiate the polymerization of monomer vapors, such as ethyl cyanoacrylate, which results in the formation of a stiff poly(ethyl...
Water‐hexane interfacial preparation of photostable Au@CsPbBr3 (Au@CPB) hybrid nanocrystals (NCs) from pure CsPbBr3 (CPB) NCs is reported, with the coexistence of exciton and localized surface plasmon resonance with equal dominance. This enables strong exciton‐plasmon coupling in these plasmonic perovskite NCs where not only the photoluminescence is quenched intrinsically due to ultrafast charge separation,...
Nanozymes with peroxidase‐mimic activity have recently emerged as effective strategies for eliminating infections. However, challenges in enhancing catalytic activities and the ability to target bacteria have hindered the broader application of nanozymes in bacterial infections. Herein, a novel nanozyme based on mesoporous CeO2 nanosphere and meso‐tetra(4‐carboxyphenyl)porphine (TCPP) encapsulated...
In this study, germanium arsenide (GeAs) is investigated as a promising nanomaterial for application in triboelectric nanogenerators and green energy harvesting. The mechanical and electrical properties of mechanically exfoliated GeAs on silica substrates are evaluated through friction force microscopy and Kelvin probe force microscopy, respectively. First, it is observed that the surface potential/work...
VO2 material, as a promising intercalation host, is widely investigated not only in aqueous lithium‐ion batteries, but also in aqueous zinc‐ion batteries (AZIBs) owing to its stable tunnel‐like framework and multivalence of vanadium. Different from lithium‐ion storage, VO2 can provide higher capacity when storing zinc ions, even exceeding its theoretical capacity (323 mAh g−1), but the specific reason...
The capacity to self‐detect and locate damage to underwater infrastructure in emergencies is vital, as materials and technologies that securely facilitate energy and information transmission are crucial in several fields. Herein, the development of a multifunctional supramolecular ionogel (SIG) and SIG‐based devices for use in detecting and locating damage to underwater infrastructure is reported...
Most exogenous electronic skins (e‐skins) currently face challenges of complex structure and poor compatibility with the human body. Utilizing human secretions (e.g., sweat) to develop e‐skins is an effective solution strategy. Here, a new kind of “sweat‐driven” e‐skin is proposed, which realizes energy‐storage and thermal‐management multifunctions. Through the layer‐by‐layer assembly of MXene‐carbon...
Injectable hydrogels find extensive application in the treatment of diabetic wound healing. However, traditional bulk hydrogels are significantly limited due to their nano‐porous structure, which obstructs cell migration and tissue infiltration. Moreover, regulating inflammation and matrix metalloproteinase ‐9 (MMP‐9) expression in diabetic wounds is crucial for enhancing wound healing. This study...
Electrolyte‐gated transistors have strong potential for high‐performance artificial synapses in neuromorphic bio‐interfaces owing to their outstanding synaptic characteristics, low power consumption, and human‐like mechanisms. However, the short retention time is a hurdle to overcome owing to the natural diffusion of protons. Here, a novel modulation technique of ionic conductivity is proposed with...

The fabrication of a highly controlled gold (Au) nanohole (NH) array via tip‐based lithography is improved by incorporating a sacrificial layer—a tip‐crash buffer layer. This inclusion mitigates scratches during the nano‐indentation process by employing a 300 nm thick poly(methyl methacrylate) layer as a sacrificial layer on top of the Au film. Such a precaution ensures minimal scratches on the Au...

Ligand and ion exchange...
Compared with all‐small‐molecule (ASM) and other types of organic solar cells (OSCs), the small molecule donor:polymer acceptor (SMD:PA) OSCs develop much slower due to the lack of material matching rules.
