Piezocatalysis has increasingly gained prominence due to its enormous potential for addressing energy shortages and environmental pollution issues. Nonetheless, the low piezocatalytic activity of state‐of‐the‐art materials seriously inhibits the practical applications of piezocatalysis. Here, it is proposed to greatly enhance the piezocatalytic activity for a perovskite ferroelectric, i.e., Sm‐doped...
Lithium metal batteries are intensively studied due to the potential to bring up breakthroughs in high energy density devices. However, the inevitable growth of dendrites will cause the rapid failure of battery especially under high current density. Herein, the utilization of tetrachloroethylene (C2Cl4) is reported as the electrolyte additive to induce the formation of the LiCl‐rich solid electrolyte...
Exploring highly active and durable electrocatalysts for oxygen evolution reaction (OER) is significant to achieve efficient anion exchange membrane (AEM) water electrolysis. Herein, hollow Co‐based N‐doped porous carbon spheres decorated with ultrafine Ru nanoclusters (HS‐RuCo/NC) are reported as efficient OER electrocatalysts via the pyrolysis of carboxylate‐terminated polystyrene‐templated bimetallic...
It remains a great challenge to design and manufacture battery‐type supercapacitors with satisfactory flexibility, appropriate mechanical property, and high energy density under high power density. Herein, a concept of porous engineering is proposed to simply prepare two‐layered bimetallic heterojunction with porous structures. This concept is successfully applied in fabrication of flexible electrode...
Directly converting and storing abundant solar energy in next‐generation energy storage devices is of central importance to build a sustainable society. Herein, a new prototype of a light‐promoted rechargeable and flexible Li‐CO2 battery with a TiO2/carbon cloth (CC) cathode is reported for the direct utilization of solar energy to promote the kinetics of the carbon dioxide reduction reaction and...
Solution‐processed zinc oxide (ZnO) is one of the widely used electron transporting layers (ETLs) for organic solar cells (OSCs). However, low optical transparency along with thickness‐sensitivity of ZnO ETL constrains the improvement of photovoltaic performance and large‐scale fabrication compatibility. To resolve these issues, zirconium (Zr) doping is applied to tailor the optoelectronic and morphological...
In article number 1803428, Jian Lin and co‐workers report the discovery of a novel self‐assembled metal protein nanoparticle, designated GST‐MT‐3, which targets the mitochondria of cancer cells within 30 min in vitro and rapidly accumulates in tumors within 1 h in vivo. The little men carrying the bombs represent GST‐MT3 protein nanoparticles loading the cobalt ions. Through the blood vessels they...
Self‐assembled protein nanoparticles have attracted much attention in biomedicine because of their biocompatibility and biodegradability. Protein nanoparticles have become widely utilized as diagnostic or therapeutic agents for various cancers. However, there are no reports that protein nanoparticles can specifically target mitochondria. This targeting is desirable, since mitochondria are critical...
Based on biocompatible and stretchable hydrogels, Fei Li, Feng Xu, and co‐workers propose a simple paradigm to prototype stretchable electronics with an embedded 3D helical conductive layout in article number 1801711. The 3D layout promises enhanced stretchability and robustness compared to traditional 1D and 2D designs. The hydrogel electronics can be directly incorporated onto the human body and...
The ever‐growing overlap between stretchable electronic devices and wearable healthcare applications is igniting the discovery of novel biocompatible and skin‐like materials for human‐friendly stretchable electronics fabrication. Amongst all potential candidates, hydrogels with excellent biocompatibility and mechanical features close to human tissues are constituting a promising troop for realizing...
The hollow noble metal nanostructures have attracted wide attention in catalysis/electrocatalysis. Here a two‐step procedure for constructing hollow Rh nanospheres (Rh H‐NSs) with clean surface is described. By selectively removing the surfactant and Au core of Au‐core@Rh‐shell nanostructures (Au@Rh NSs), the surface‐cleaned Rh H‐NSs are obtained, which contain abundant porous channels and large specific...
Tungsten ditelluride (WTe2) is a semimetal with orthorhombic Td phase that possesses some unique properties such as Weyl semimetal states, pressure‐induced superconductivity, and giant magnetoresistance. Here, the high‐pressure properties of WTe2 single crystals are investigated by Raman microspectroscopy and ab initio calculations. WTe2 shows strong plane‐parallel/plane‐vertical vibrational anisotropy,...
