The shuttle effect, which causes the loss of active sulfur, passivation of lithium anode, and leads to severe capacity attenuation, is currently the main bottleneck for lithium‐sulfur batteries. Recent studies have disclosed that molybdenum compounds possess exceptional advantages as a polar substrate to immobilize and catalyze lithium polysulfide such as high conductivity and strong sulfiphilicity...
Here, a rational strategy to achieve multifunctional N, S codoped carbon dots (N, S‐CDs) is reported, aiming to improve the photoluminescence quantum yields (PLQYs) of the CDs. The synthesized N, S‐CDs have excellent stability and emission properties independent of excitation wavelength. Through the introduction of S element doping, the fluorescence emission of CDs is red‐shifted from 430 to 545 nm,...
Developing effective catalysts to degrade chemical warfare agents is of great significance. Herein, a mesoporous MIL‐101(Cr) composite material dangled with porphyrin molecules (denote as TCPP@MIL‐101(Cr), TCPP = tetra(4‐carboxyphenyl)porphyrin) is reported, which can be used as a heterogeneous photocatalyst for detoxification of mustard gas simulants 2‐chloroethyl ethyl sulfide (CEES) to 2‐chloroethyl...
Aqueous rechargeable zinc‐ion batteries (ZIBs) have attracted burgeoning interests owing to the prospect in large‐scale and safe energy storage application. Although manganese oxides are one of the typical cathodes of ZIBs, their practical usage is still hindered by poor service life and rate performance. Here, a MnO2–carbon hybrid framework is reported, which is obtained in a reaction between the...
Diabetic Wound Healing
In article number 2205489, Jinshan Guo, Keke Wu, and co‐workers develop an on‐demand removable, pH‐responsive europium‐releasable and photothermal antimicribal adhesive dressing for diabetic wound healing. The adhesive provides convenient non‐invasive wound closure, enables in‐time painless dressing change upon mixing with borax solution, and smoothly connects inflammatory microenvironment...
Current diabetic wound treatments remain unsatisfactory due to the lack of a comprehensive strategy that can integrate strong applicability (tissue adhesiveness, shape adaptability, fast self‐healability, and facile dressing change) with the initiation and smooth connection of the cascade wound healing processes. Herein, benefiting from the multifaceted bonding ability of tannic acid to metal ions...
Due to their marvelous electrical and optical properties, perovskite nanocrystals have reached remarkable landmarks in solar cells, light‐emitting diodes, and photodetectors. However, the intrinsic instability of ionic perovskites, which would undergo an undesirable phase transition and decompose rapidly in ambient humidity, limits their long‐term practical deployment. To address this challenge, halogenated...
Using the MoS2‐WTe2 heterostructure as a model system combined with electrochemical microreactors and density function theory calculations, it is shown that heterostructured contacts enhance the hydrogen evolution reaction (HER) activity of monolayer MoS2. Two possible mechanisms are suggested to explain this enhancement: efficient charge injection through large‐area heterojunctions between MoS2 and...
Size, shape, and protein corona play a key role in cellular uptake and removal mechanisms of gold nanoparticles (Au NPs). The 15 nm nanoparticles (NP1), the 45 nm nanoparticles (NP2), and the rod‐shaped nanoparticles (NR) enter into cells via a receptor‐mediated endocytosis (RME) pathway. The star‐shaped nanoparticles (NS) adopt not only clathrin‐mediated, but also caveolin‐mediated endocytosis pathways...
