Carbon Dot‐Based Hydrogels
The features of article number 2207048 by Xiaofeng Sun, Jin Zhou, Hongguang Li, and co‐workers include i) preparations of carbon dot (CD)‐based hydrogels, including CDs/polymers, CDs/low molecular weight gelators, CDs/graphene oxide, CDs/metal ions and derivatives of CD‐based hydrogels, ii) properties of CD‐based hydrogels, such as fluorescence, mechanical strength enhancement,...
Hydrogels have extremely high moisture content, which makes it very soft and excellently biocompatible. They have become an important soft material and have a wide range of applications in various fields such as biomedicine, bionic smart material, and electrochemistry. Carbon dot (CD)‐based hydrogels are based on carbon dots (CDs) and auxiliary substances, forming a gel material with comprehensive...
Nitrogen dioxide (NO2) emission has severe impact on human health and the ecological environment and effective monitoring of NO2 requires the detection limit (limit of detection) of several parts‐per‐billion (ppb). All organic semiconductor‐based NO2 sensors fail to reach such a level. In this work, using an ion‐in‐conjugation inspired‐polymer (poly(3,3′‐diaminobenzidine‐squarine, noted as PDBS) as...
Recently, organic–inorganic hybrid perovskites (OIHP) are studied in memory devices, but ternary resistive memory with three states based on OIHP is not achieved yet. In this work, ternary resistive memory based on hybrid perovskite is achieved with a high device yield (75%), much higher than most organic ternary resistive memories. The pseudohalide‐induced 2D (CH3NH3)2PbI2(SCN)2 perovskite thin film...
