In situ forming gel polymer electrolyte (GPE) is one of the most feasible ways to improve the safety and cycle performances of lithium metal batteries with high energy density. However, most of the in situ formed GPEs are not compatible with high‐voltage cathode materials. Here, this work provides a novel strategy to in situ form GPE based on the mechanism of Ritter reaction. The Ritter reaction in...
Dual single atoms catalysts have promising application in bifunctional electrocatalysis due to their synergistic effect. However, how to balance the competition between rate‐limiting steps (RDSs) of reversible oxygen reduction and oxygen evolution reaction (OER) and fully expose the active centers by reasonable structure design remain enormous challenges. Herein, Fe/N4 and Ni/N4 sites separated on...
Phase separation is a trivial phenomenon but a mature strategy in materials science. The flexible materials are provided toughness and strength by phase separation, yet there are few applications in optics and electronics industry. A novel phase‐separated dielectric gel (PSDG) with a strong Christiansen effect is prepared via radical polymerization using hydroxyethyl methacrylate as a monomer, 4‐cyano‐4′‐pentylbiphenyl...
Developing novel, efficient, and low‐cost 3D FeNi‐based oxygen evolution reaction (OER) catalysts with the special hydrophilic channel is still a challenge for improving hydrogen production efficiency. Herein, a novel 3D ethoxy substituted FeNi oxalate (ENWs‐FeNi‐C2O4) nanowires network catalyst with hydrophilic channels is reported firstly, which shows an outstanding OER activity with a low overpotential...
All‐in‐One Theranostics
In article number 2104660, Xin Jia, Bo Han, and co‐workers coordinate bismuth ions and natural polyphenols into a metal phenolic network (MPN). Tetracycline is used as a model drug to evaluate the efficacy and drug carrying capacity of the MPN. The results show that the drug delivery system constructed in this work provides a versatile intragastric‐targeting all‐in‐one theranostic...
Bismuth‐containing therapies are suggested as first‐line and rescue alternatives for gastric ulcer (GU) treatment and Helicobacter pylori eradication. The current treatment strategy is called quadruple therapy and includes proton pump inhibitors, bismuth, and two broad‐band antibiotics. This fact may affect medication compliance, leading to a resistance rate of more than 25% to clarithromycin or metronidazole...
