Abstract While there has been extensive investigation into modulating quasi‐2D perovskite compositions in light‐emitting diodes (LEDs) for promoting their electroluminescence, very few reports have studied approaches involving enhancement of the energy transfer between layers film, which plays important role achieving high‐performance LEDs (PeLEDs). In this work, a bifunctional ligand 4‐(2‐aminoethyl)benzoic acid (ABA) cation is strategically introduced to diminish weak van der Waals gap...
Abstract Rapid advances in wearable electronics and mechno‐sensational human–machine interfaces impose great challenges developing flexible deformable tactile sensors with high efficiency, ultra‐sensitivity, environment‐tolerance, self‐sustainability. Herein, a hydrogel sensor (THS) based on micro‐pyramid‐patterned double‐network (DN) ionic organohydrogels to detect subtle pressure changes by measuring the variations of triboelectric output signal without an external power supply is...

Abstract Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) able to work in acidic working conditions are elusive. While many first-row transition metal oxides competitive alkaline media, most of them just dissolve or become inactive at high proton concentrations where hydrogen is preferred. Only noble-metal catalysts, such as IrO 2 , fast and stable enough media. Herein, we report excellent activity long-term stability Co 3 O 4 -based anodes 1 M H SO (pH 0.1) when...

Intrinsically chiral oxides show enhanced activity towards the oxygen evolution reaction in full cell electrolysers. Enantiopure active sites were detected operando by circular dichroism-spectro-electrochemical data.
Nickel oxide (NiOx) is a promising hole-transporting material for perovskite light-emitting diodes (PeLEDs) because of its low cost, excellent stability, and simple fabrication process. However, the electroluminescence efficiencies NiOx-based PeLEDs are greatly limited by inefficient hole injection exciton quenching at NiOx-perovskite interfaces. Here, novel interfacial engineering method with sodium dodecyl sulfate-oxygen plasma (SDS-OP) demonstrated to simultaneously overcome...

Herein, we propose novel ether-based copolymer-based gel polymer (ECP-based GPE) situ...
