Stretchable wearable thermoelectric (TE) generators (WTEGs) without compromising output performance for real wearables have attracted much attention recently. Herein, a 3D thermoelectric generator with biaxial stretchability is constructed on the device level. Ultraflexible inorganic Ag/Ag2Se strips are sewn into the soft purl‐knit fabric, in which the thermoelectric legs are aligned in the direction...
Developing efficient heterojunction electrocatalysts and uncovering their atomic‐level interfacial mechanism in promoting sulfur‐species adsorption‐electrocatalysis are interesting yet challenging in lithium‐sulfur batteries (LSBs). Here, multifunctional SnS2‐MXene Mott–Schottky heterojunctions with interfacial built‐in electric field (BIEF) are developed, as a model to decipher their BIEF effect...
The tremendous volume change and severe pulverization of micro‐sized Sb anode generate no stable capacity in potassium‐ion batteries (PIBs). The honeycomb‐like porous structure provides free spaces to accommodate its volume expansion and offers efficient ion transport, yet complex synthesis and low yield limits its large‐scale application. Here, a green, scalable template‐free method for designing...
Potassium Storage
In article number 2204045, Hongyan Li and co‐workers present a unique spindle‐like bismuth‐based composite (SPB@NC) employed as anode for a potassium ion battery, which exhibits ultrafast potassium storage enhanced by the favorable electrode structure and the presence of BiOC bonds.
Bismuth (Bi)‐based materials have attracted great attention as anodes in potassium ion batteries (PIBs) for their high theoretical capacity and suitable voltage range. Herein, the authors report a unique spindle‐like structured Bi@N‐doped carbon composite (SPB@NC) consisting of interconnected nano‐Bi coated heteroatom‐doped hard carbon layer via an interesting in situ carbon thermal reduction method...
It is a big challenge to reveal the intrinsic cause of a nanotoxic effect due to diverse branches of signaling pathways induced by engineered nanomaterials (ENMs). Biotransformation of toxic ENMs involving biochemical reactions between nanoparticles (NPs) and biological systems has recently attracted substantial attention as it is regarded as the upstream signal in nanotoxicology pathways, the molecular...
