Most exogenous electronic skins (e‐skins) currently face challenges of complex structure and poor compatibility with the human body. Utilizing human secretions (e.g., sweat) to develop e‐skins is an effective solution strategy. Here, a new kind of “sweat‐driven” e‐skin is proposed, which realizes energy‐storage and thermal‐management multifunctions. Through the layer‐by‐layer assembly of MXene‐carbon...
Herein, a hybrid substrate for surface‐enhanced Raman scattering (SERS) is fabricated, which couples localized surface plasmon resonance (LSPR), charge transfer (CT) resonance, and molecular resonance. Exfoliated 2D TiS2 nanosheets with semimetallic properties accelerate the CT with the tested analytes, inducing a remarkable chemical mechanism enhancement. In addition, the LSPR effect is coupled with...
Sluggish redox kinetics and shuttle effect of polysulfides hinder the extensive application of the lithium–sulfur batteries (LSBs). Herein a functional heterostructure of boron nitride (BN) and MXene with an alternately layered structure (BN@MXene) is designed as separator interlayer. High efficiency Li+ transmission, uniform lithium deposition, strong adsorption, and efficient catalytic conversion...
Oxygen electrocatalysis has aroused considerable interest over the past years because of the new energy technologies boom in hydrogen energy and metal–air battery. However, due to the sluggish kinetic of the four‐electron transfer process in oxygen reduction reaction and oxygen evolution reaction, the electro‐catalysts are urgently needed to accelerate the oxygen electrocatalysis. Benefit from the...
Investigating dendrite‐free stripping/plating anodes is highly significant for advancing the practical application of aqueous alkaline batteries. Sn has been identified as a promising candidate for anode material, but its deposition/dissolution efficiency is hindered by the strong electrostatic repulsion between Sn(OH)3− and the substrate. Herein, this work constructs a nondense copper layer which...
CO2 electrolysis is a promising route for achieving net‐zero emission through decarbonization. To realize CO2 electrolysis toward practical application, beyond catalyst structures, it is also critical to rationally manipulate catalyst microenvironments such as the water at the electrode/electrolyte interface. Here, the role of interfacial water in CO2 electrolysis over Ni‐N‐C catalyst modified with...
Solar energy‐driven water evaporation is a promising sustainable strategy to purify seawater and contaminated water. However, developing solar evaporators with high water evaporation rates and excellent salt resistance still faces a great challenge.

Platinum group metal (PGM)‐free M‐N‐C catalysts have exhibited dramatic electrocatalytic performance and are considered the most promising candidate of the Pt catalysts in oxygen reduction reaction (ORR). However, the electrocatalytic performance of the M‐N‐C catalysts is still limited by their inferior intrinsic activity and finite active site density. Regulating the coordination environment and...
An atomically thin TaSe2 sample, approximately containing two to three layers of TaSe2 nanosheets with a diameter of 2.5 cm is prepared here for the first time and applied on the detection of various Raman‐active molecules. It achieves a limit of detection of 10−10 m for rhodamine 6G molecules. The excellent surface‐enhanced Raman scattering (SERS) performance and underlying mechanism of TaSe2 are...
H2S‐mediated tumor therapy has received great attention due to its unique physiological activity and synergistical enhancement, but suffers from limited H2S donors with promised biosafety to regulate the H2S delivery and subsequently the elusive pathway to augment the combined therapy. Herein, a PEGylated porous molybdenum disulfide nanoflower (MSP) with abundant defects is facilely synthesized for...

The progress of antitumor immunotherapy is usually limited by tumor‐associated macrophages (TAMs) that account for the highest proportion of immunosuppressive cells in the tumor microenvironment, and the TAMs can also be reversed by modulating the M2‐like phenotype. Herein, a biomimetic polymer magnetic nanocarrier is developed with selectively targeting and polarizing TAMs for potentiating immunotherapy...
Regulating the coordination environment of atomically dispersed catalysts is vital for catalytic reaction but still remains a challenge. Herein, an ionic exchange strategy is developed to fabricate atomically dispersed copper (Cu) catalysts with controllable coordination structure. In this process, the adsorbed Cu ions exchange with Zn nodes in ZIF‐8 under high temperature, resulting in the trapping...
In article number 2001384, Yi Wang, Yunteng Qu, Jinbo Bai, and co‐workers develop an ionic exchange strategy to fabricate atomically dispersed CuNC material with unsaturated CuN3 centers.
