Study on the effects of silica aerogels on the performance of APG0810/PMH fluorine-free foam

Jinwei Xu, Hongxiang Ou, Jiawen Su, Panpan Li et autres

Perfluorooctane sulfonate (PFOS) serves as the primary ingredient in aqueous film-forming foam used for extinguishing fires. Nevertheless, PFOS is recognized as a persistent organic pollutant. Therefore, creating environmentally friendly fluorine-free foam (FFF) extinguishing agents is of great significance. To formulate fluorine-free foam …

Structural Confinement Engineering of Cr 3+ in Nanocrystalline Spinel Glass‐Ceramics for Efficient and Thermally Robust Deep‐Red Plant‐Growth LEDs

Yunshan Xu, Ping Zhang, Qi Chen, Minggui Zhang et autres

ABSTRACT Sustainable high‐yield agriculture in controlled environments demands lighting with spectral precision and thermal robustness. Deep‐red light at 680–690 nm aligns with photosynthetic pigment absorption maxima, enhancing efficiency and regulating plant photomorphogenesis. However, emitters combining spectral precision, high quantum efficiency, and thermal …

Revealing Single‐Atom‐Site‐Density‐Driven Kinetic Resolution in Acidic CO 2 Electroreduction

Juan Xiang, Ming Yuan, Pengfei Wang, Panpan Li et autres

ABSTRACT Acidic electrochemical CO 2 reduction to CO offers a potentially carbon‐efficient route for electrosynthesis because it can, in principle, mitigate carbonate formation under continuous‐flow operation, yet this advantage is fundamentally constrained by kinetically competitive hydrogen evolution in proton‐rich environments. Here we …

Ladder Acenes: Staircase-Bending Nanographenes

Yuying Lan, Wenying Dai, Chufeng Xiong, Kai TAO et autres

Two nonplanar nanographenes, namely, L8 and L9, were developed by linearly fusing two contorted hexabenzocoronene subunits into an octacene and a nonacene backbone, respectively. Single-crystal X-ray diffraction revealed their staircase-bending backbones and waggling periphery benzenoid rings with lengths of 1.95 and 2.18 …

Underwater Wireless Optical Communication Enabled by Self‐Crystallized Luminescent Nanocrystals in Borogermanate Glass

Binfeng Liang, Panpan Li, Weichao Wang, Qi Zhang

ABSTRACT Underwater wireless optical communication (UWOC) demands light sources that simultaneously offer cyan emission (480–490 nm), high photoluminescence quantum yield (PLQY), and long‐term stability. However, current approaches face a persistent trilemma involving the wavelength mismatch of commercial light sources, poor stability of …

Applications of Nanoscale Electrochemical Characterization Techniques in the Oxygen Evolution Reaction

Qingling Chen, Panpan Li, Zhaoyu Jin

Water electrolysis provides a sustainable route for hydrogen production, yet its overall efficiency is largely constrained by the sluggish kinetics of the oxygen evolution reaction (OER). Although substantial progress has been achieved in improving the activity and stability of OER electrocatalysts, the …

Single-Atom Supports: Versatile Platforms for Regulating Electrocatalysts at the Atomic Level

Ming Yuan, Wenjun Guo, Juan Xiang, Dongqi Yang et autres

Abstract Atomic-level control of metal–support interfaces is a key lever for electrocatalysis with low energy input, high selectivity, and long-term durability. While single-atom catalysts maximize atom utilization and provide well-defined coordination motifs, their isolated sites can limit cooperativity and compromise stability under …
