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...
The coupling of photocatalytic hydrogen production and selective oxidation of benzylamine is a topic of significant research interest. However, enhancing the bifunctional photocatalytic activity in this context is still a major challenge. The construction of Z‐scheme heterojunctions is an effective strategy to enhance the activity of bifunctional photocatalysts. Herein, a p‐n type direct Z‐scheme...
Solid‐state batteries have become the most anticipated option for compatibility with high‐energy density and safety. In situ polymerization, a novel strategy for the construction of solid‐state systems, has extended its application from solid polymer electrolyte systems to other solid‐state systems. This review summarizes the application of in situ polymerization strategies in solid‐state batteries,...
The carrier concentration in n‐type layered Bi2Te3‐based thermoelectric (TE) material is significantly impacted by the donor‐like effect, which would be further intensified by the nonbasal slip during grain refinement of crushing, milling, and deformation, inducing a big challenge to improve its TE performance and mechanical property simultaneously. In this work, high‐energy refinement and hot‐pressing...
Broadband infrared (IR) absorption is sought after for wide range of applications. Graphene can support IR plasmonic waves tightly bound to its surface, leading to an intensified near‐field. However, the excitation of graphene plasmonic waves usually relies on resonances. Thus, it is still difficult to directly obtain both high near‐field intensity and high absorption rate in ultra‐broad IR band....
Disturbed blood flow induces endothelial pro‐inflammatory responses that promote atherogenesis. Nanoparticle‐based therapeutics aimed at treating endothelial inflammation in vasculature where disturbed flow occurs may provide a promising avenue to prevent atherosclerosis. By using a vertical‐step flow apparatus and a microfluidic chip of vascular stenosis, herein, it is found that the disk‐shaped...
Transition metal oxides (TMOs) as high‐capacity electrodes have several drawbacks owing to their inherent poor electronic conductivity and structural instability during the multi‐electron conversion reaction process. In this study, the authors use an intrinsic high‐valent cation substitution approach to stabilize cation‐deficient magnetite (Fe3O4) and overcome the abovementioned issues. Herein, 5...
GaN‐based lateral Schottky barrier diodes (SBDs) have attracted great attention for high‐power applications due to its combined high electron mobility and large critical breakdown field. However, the breakdown voltage (BV) of the SBDs are far from exploiting the material advantages of GaN at present, limiting the desire to use GaN for ultra‐high voltage (UHV) applications. Then, a golden question...
Schottky Barrier Diodes
GaN is a promising candidate for next‐generation power electronic devices, but its potential is far from being realized. In article number 2107301, Peng Chen, Rong Zhang, Youdou Zheng, and co‐workers demonstrate a high power figure‐of‐merit, 10.6‐kV AlGaN/GaN lateral Schottky barrier diode with single channel, and sub‐100‐μm anode‐to‐cathode spacing without any other additional...
The photocatalytic efficiency of polymeric carbon nitride is hampered by high carrier recombination rate and low charge transfer. Herein, these issues are addressed by constructing 1D strip‐like carbon nitride with a large π‐electron conjugated system from carbon‐doping, realizing the synchronization control of its electronic structure and morphology. Nicotinic acid, a monomer with the carboxyl group...
2D transition metal dichalcogenides (TMDs) based photodetectors have shown great potential for the next generation optoelectronics. However, most of the reported MoS2 photodetectors function under the photogating effect originated from the charge‐trap mechanism, which is difficult for quantitative control. Such devices generally suffer from a poor compromise between response speed and responsivity...
