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...
Transition metal oxides, highly motivated anodes for lithium‐ion batteries due to high theoretical capacity, typically afflict by inferior conductivity and significant volume variation. Architecting heterogeneous structures with distinctive interfacial features can effectively regulate the electronic structure to favor electrochemical properties. Herein, an engineered carbon‐coated nanosized Fe3O4...
Surface antibacterial coatings with outstanding antibacterial efficiency have attracted increasing attention in medical protective clothing and cotton surgical clothing. Although nanozymes, as a new generation of antibiotics, are used to combat bacteria, their catalytic performance remains far from satisfactory as alternatives to natural enzymes. Single‐atom nanodots provide a solution to the low...
Heterogeneous atoms substitution is an efficient method for promoting Li+ storage of transition metal oxides. Herein, a series of Fe‐substituted MnO solid solutions with different Fe contents are synthesized by a feasible solid‐phase method. The synergistic effects between heterogeneous atoms and rich vacancies are synchronously obtained, which hold distinctive electronic structures and substantial...
Luminescence imaging is one of the most effective noninvasive strategies for detection and stratification of inflammation and oxidative stress that are closely related to the pathogenesis of numerous acute and chronic diseases. Herein biocompatible nanoparticles based on a peroxalate ester derived from vitamin E (defined as OVE) are developed. In combination with different fluorophores, OVE can generate...
For the first time Janus‐like films of surface‐acylated cellulose nanowhiskers (CNWs) with or without graphene oxide (GO) via one‐step evaporation‐driven self‐assembly process are reported, which have reconstructible time‐dependent micro‐/nanostructures and asymmetric wettability. The heterogeneous aggregation of CNWs on rough Teflon substrates favors the formation of uniform films, leading to hydrophobic...
In article number 2004922, Qiyun Tang, Kai Zhang, and co‐workers report Janus‐like films fabricated via the self‐assembly of surface‐acylated cellulose nanowhiskers (CNWs) with or without graphene oxide (GO). The obtained films with asymmetric topographies and properties on their top and bottom surfaces show different wettabilities and fast solvent‐responsive actuation. The self‐assembled patchy microspheres...
It has been thought that water is detrimental to perovskites, causing degeneration due to their ionic structures. In article number 1901994, Wen Li, Wei Yan, Weiqing Yang, and co‐workers unexpectedly find that 3D all‐inorganic perovskites are exfoliated by water molecules and transformed into more intrinsic stable quasi‐2D nanosheets in complete water conditions instead of leading to decomposition...
All‐inorganic cesium lead halide perovskite nanocrystals (NCs) have emerged as attractive optoelectronic materials due to the excellent optical and electronic properties. However, their environmental stability, especially in the presence of water, is still a significant challenge for their further commercialization. Here, ultrahigh intrinsically water‐stable all‐inorganic quasi‐2D CsPbBr3 nanosheets...
A novel anode material for lithium‐ion batteries derived from aromatic imides with multicarbonyl group conjugated with aromatic core structure is reported, benzophenolne‐3,3′,4,4′‐tetracarboxylimide oligomer (BTO). It could deliver a reversible capacity of 829 mA h g−1 at 42 mA g−1 for 50 cycles with a stable discharge plateaus ranging from 0.05–0.19 V versus Li+/Li. At higher rates of 420 and 840...
In article number 1601250, H. Liu and co‐workers reveal that by rationally designing the superhydrophobic electrodes with different underwater wetting state, only the underwater Wenzel‐Cassie state shows a clearly enhanced ability in catalyzing ORR, a typical underwater gas‐consuming reaction at electrode. It is proposed that maximizing and stabilizing the liquid/gas/solid triphase interface, endowed...
By rationally designing superhydrophobic electrodes with different underwater wetting states, it is revealed that only the underwater Wenzel‐Cassie coexistent state shows the clearly enhanced ability in catalyzing the oxygen reduction reaction, a typical underwater gas‐consuming reaction at electrode. It is proposed that the maximizing and stabilizing the liquid/gas/solid triphase interface, endowed...
