Nanozyme‐driven catalytic antibacterial therapy has become a promising modality for bacterial biofilm infections. However, current catalytic therapy of biofilm wounds is severely limited by insufficient catalytic efficiency, excessive inflammation, and deep tissue infection. Drawing from the homing mechanism of natural macrophages, herein, a hollow mesoporous biomimetic single‐atomic nanozyme (SAN)...
Developing nature‐inspired nanomaterials with enzymatic activity is essential in combating bacterial biofilms. Here, it is reported that incorporating the carboxylic acid in phenolic/Fe nano‐networks can efficiently manipulate their peroxidase‐like activity via the acidic microenvironment and neighboring effect of the carboxyl group. The optimal gallic acid/Fe (GA/Fe) nano‐networks demonstrate highly...
Fine‐tuning the crystallinity and self‐aggregation features of donors/acceptor materials toward high‐efficiency organic solar cells (OSCs) is of crucial importance. Here, a convenient yet effective way to simultaneously control the crystallinity and self‐aggregation of the fused ring electron acceptor (FREA) is demonstrated by altering the length of the first‐position branched alkyl chain on the cyclic...
Oxidative stress and local overactive inflammation have been considered major obstacles in diabetic wound treatment. Although antiphlogistic tactics have been reported widely, they are also challenged by pathogen contamination and compromised angiogenesis. Herein, a versatile integrated nanoagent based on 2D reductive covalent organic frameworks coated with antibacterial immuno‐engineered exosome...
The novel coronavirus SARS‐CoV‐2 has prompted a worldwide pandemic and poses a great threat to public safety and global economies. Most present personal protective equipment (PPE) used to intercept pathogenic microorganisms is deficient in biocidal properties. Herein, we present green nanofibers with effective antibacterial and antiviral activities that can provide sustainable bioprotection by continuously...
A new family of transition‐metal monosilicides (MSi, M = Ti, Mn, Fe, Ru, Ni, Pd, Co, and Rh) electrocatalysts with superior electrocatalytic performance of hydrogen evolution is reported, based on the computational and experimental results. It is proposed that these MSi can be synthesized within several minutes by adopting the arc‐melting method. The previously reported RuSi is not only fabricated...
Ceramic‐sulfide solid electrolytes are a promising material system for enabling solid‐state batteries. However, one challenge that remains is the discrepancy in the reported electrochemical stability. Recent work has suggested that it may be due to the sensitivity of ceramic sulfides to mechanically induced stability. Small changes in ceramic‐sulfide microstructure, for example, have been shown to...
