Redox‐induced interconversions of metal oxidation states typically result in multiple phase boundaries that separate chemically and structurally distinct oxides and suboxides. Directly probing such multi‐interfacial reactions is challenging because of the difficulty in simultaneously resolving the multiple reaction fronts at the atomic scale. Using the example of CuO reduction in H2 gas, a reaction...
Rechargeable aqueous zinc–ion batteries are regarded as promising energy storage devices due to their attractive economic benefits and extraordinary electrochemical performance. However, the sluggish Zn2+ mass transfer behavior and water‐induced parasitic reactions that occurred on the anode–electrode interface inevitably restrain their applications. Herein, inspired by the selective permeability...
Aqueous zinc‐ion batteries (AZIBs) are considered to be one of the most promising devices for large‐scale energy storage systems owing to their high theoretical capacity, environmental friendliness, and safety. However, the ionic intercalation or surface redox mechanisms in conventional cathode materials generally result in unsatisfactory capacities. Conversion‐type aqueous zinc–tellurium (Zn–Te)...

In article number 2304324, Yi Deng, Kunneng Liang, and co‐workers report the innovative P‐N bio‐heterojunction (bio‐HJ) material with infection‐primed H2S liberation. In this system, fast sterilization is achieved through the self‐built‐in electric field intensified photodynamics therapy and photothermal therapy. Meanwhile, H2S generated in situ from bio‐HJs accelerates revascularization...
Photodynamic therapy (PDT) acts as a powerful weapon against infectious diseases for its enormous antimicrobial activity that quickly elicits storms of reactive oxygen species (ROS). Nevertheless, redundant ROS during treatment inevitably bring detriments in revascularization. To address this dilemma, an innovative P‐N bio‐heterojunction (bio‐HJ) material consisting of p‐type copper sulfide (p‐CuS),...
Van der Waals (vdW) metal–semiconductor junctions (MSJs) exhibit huge potential to reduce the contact resistance and suppress the Fermi‐level pinning (FLP) for improving the device performance, but they are limited by optional (2D) metals with a wide range of work functions. Here a new class of vdW MSJs entirely composed of atomically thin MXenes is reported. Using high‐throughput first‐principles...
A photo‐ and electro‐thermal film can convert sunlight and electricity into heat to solve icing problems. Combination of them provides an efficient strategy for all‐day anti‐/de‐icing. However, only opaque surfaces have been reported, due to the mutual exclusiveness between photon absorption and transmission. Herein, a highly transparent and scalable solution‐processed photo‐electro‐thermal film is...
Atmospheric water harvesting is considered a viable source of freshwater to alleviate water scarcity in an arid climate. Water condensation tends to be more efficient on superhydrophobic surfaces as the spontaneous coalescence‐induced droplet jumping on superhydrophobic surfaces enables faster condensate removal. However, poor water nucleation on these surfaces leads to meager water harvest. A conventional...

In article number 2301561, King Lun Yeung and co‐workers develop a flexible and hierarchically branched siloxane brushes by repeated grafting of siloxane on TiO2 nanorods. The flexible siloxane facilitates water nucleation, while the branched structure promotes efficient droplet jumping. The as‐prepared surface displays a significant improvement in water harvesting at both...
Electrocatalysis is a highly promising technology widely used in clean energy conversion. There is a continuing need to develop advanced electrocatalysts to catalyze the critical electrochemical reactions. Integrating metal active species, including various metal nanostructures (NSs) and atomically dispersed metal sites (ADMSs), into metal–organic frameworks (MOFs) leads to the formation of promising...
Radiative cooling shows great promise in eco‐friendly space cooling due to its zero‐energy consumption. For subambient cooling in hot humid subtropical/tropical climates, achieving ultrahigh solar reflectance (≥96%), durable ultraviolet (UV) resistance, and surface superhydrophobicity simultaneously is critical, which, however, is challenging for most state‐of‐the‐art scalable polymer‐based coolers...
