Weak adhesion and lack of underwater self‐healability hinder advancing soft iontronics particularly in wet environments like sweaty skin and biological fluids. Mussel‐inspired, liquid‐free ionoelastomers are reported based on seminal thermal ring‐opening polymerization of a biomass molecule of α‐lipoic acid (LA), followed by sequentially incorporating dopamine methacrylamide as a chain extender, N...
Hybrid halide perovskites emerging as a highly promising class of functional materials for semiconductor optoelectronic applications have drawn great attention from worldwide researchers. In the past few years, prominent nonlinear optical properties have been demonstrated in perovskite bulk structures indicating their bright prospect in the field of nonlinear optics (NLO). Following the surge of 3D...
Mesoporousintegrated TiO2 spheres composed of numerous orderly arranged nanocrystals with a reduced lattice–lattice interface connection, display an almost four times longer electron lifetime (350 ps) than the randomly aggregated nanoparticles (80 ps), and hence enhance the corresponding photocatalytic H2 and O2 generation.
In this work, a facile aqueous synthesis method is optimized to produce Mn:ZnSe/ZnS/ZnMnS sandwiched quantum dots (SQDs). In this core–shell co‐doped system, paramagnetic Mn2+ ions are introduced as core and shell dopants to generate Mn phosphorescence and enhance the magnetic resonance imaging signal, respectively. T1 relaxivity of the nanoparticles can be improved and manipulated by raising the...
