Redox‐active tetrathiafulvalene (TTF)‐based covalent organic frameworks (COFs) exhibit distinctive electrochemical and photoelectrical properties, but their prevalent two‐dimensional (2D) structure with densely packed TTF moieties limits the accessibility of redox center and constrains their potential applications. To overcome this challenge, an 8‐connected TTF linker (TTF‐8CHO) is designed as a new...
Chronic diabetic wounds remain a worldwide challenge for both the clinic and research. Given the vicious circle of oxidative stress and inflammatory response as well as the impaired angiogenesis of the diabetic wound tissues, the wound healing process is disturbed and poorly responds to the current treatments. In this work, a nickel‐based metal‐organic framework (MOF, Ni‐HHTP) with excellent antioxidant...
The practical application of Li‐S batteries is seriously hindered due to its shuttle effect and sluggish redox reaction, which requires a better functional separator to solve the problems. Herein, polypropylene separators modified by MoS2 nanosheets with atomically dispersed nickel (Ni‐MoS2) are prepared to prevent the shuttle effect and facilitate the redox kinetics for Li‐S batteries. Compared with...
In article number 2001363, Weiwei Wu, Hossam Haick, and co‐workers develop a highly sensitive strain sensor based on nanowires. The nanowires prepared by a capillarity‐inspired imprinting method have an aligned pattern, ensuring the reproducibility of strain sensor fabrication. The nanowire‐based strain sensor exhibits versatile and superior sensing performance for subtle human motion monitoring....
Achieving highly accurate responses to external stimuli during human motion is a considerable challenge for wearable devices. The present study leverages the intrinsically high surface‐to‐volume ratio as well as the mechanical robustness of nanostructures for obtaining highly‐sensitive detection of motion. To do so, highly‐aligned nanowires covering a large area were prepared by capillarity‐based...
