Hydrogels are widely used in tissue engineering, soft robotics and wearable electronics. However, it is difficult to achieve both the required toughness and stiffness, which severely hampers their application as load‐bearing materials. This study presents a strategy to develop a hard and tough composite hydrogel. Herein, flexible SiO2 nanofibers (SNF) are dispersed homogeneously in a polyvinyl alcohol...
Emulating synaptic functionalities in optoelectronic devices is significant in developing artificial visual‐perception systems and neuromorphic photonic computing. Persistent photoconductivity (PPC) in metal oxides provides a facile way to realize the optoelectronic synaptic devices, but the PPC performance is often limited due to the oxygen vacancy defects that release excess conduction electrons...
Owing to the outstanding comprehensive properties of high energy density, excellent cycling ability, and reasonable cost, Ni‐rich layered oxides (NCM) are the most promising cathode for lithium‐ion batteries (LIBs). To further enhance the specific capacity of Ni‐rich layered oxides, it is necessary to increase the cut‐off voltage to a higher level. However, a higher cut‐off voltage can lead to substantial...
Despite gold‐based nanomaterials having a unique role in nanomedicine, among other fields, synthesis limitations relating to reaction scale‐up and control result in prohibitively high gold nanoparticle costs.

Electrocatalysis is considered to be an effective method to solve the sluggish kinetics of lithium–sulfur batteries. However, a single catalyst cannot simultaneously catalyze multi‐step sulfur reductions. And once the catalyst surface is covered by the initially deposited solid products, the subsequent catalytic activity will significantly deteriorate. Here, microporous ZIF‐67 and its derivative nano‐metallic...
Maneuver of conducting polymers (CPs) into lightweight hydrogels can improve their functional performances in energy devices, chemical sensing, pollutant removal, drug delivery, etc. Current approaches for the manipulation of CP hydrogels are limited, and they are mostly accompanied by harsh conditions, tedious processing, compositing with other constituents, or using unusual chemicals. Herein, a...
As cost‐effective catalysts, platinum (Pt) single‐atom catalysts (SACs) have attracted substantial attention. However, most studies indicate that Pt SACs in acidic hydrogen evolution reaction (HER) follow the slow Volmer‐Heyrovsky (VH) mechanism instead of the fast kinetic Volmer‐Tafel (VT) pathway. Here, this work propose that the VH mechanism in Pt SACs can be switched to the faster VT pathway for...
