Near‐neutral zinc–air batteries (ZABs) have garnered significant research interest due to their high energy density, exceptional electrochemical reversibility, and adaptability to ambient air. However, these batteries suffer from substantial electrochemical polarization, low energy efficiency, and poor rate performance. In this study, a mesoporous carbon (meso‐C) with a high specific surface area...
Glioblastoma (GBM), the most aggressive and lethal form of malignant brain tumor, is a therapeutic challenge due to the drug filtration capabilities of the blood‐brain barrier (BBB). Interestingly, glioblastoma tends to resist apoptosis during chemotherapy, but is susceptible to ferroptosis. Developing therapies that can effectively target glioblastoma by crossing the BBB and evoke ferroptosis are,...
On account of high capacity and high voltage resulting from anionic redox, Li‐rich layered oxides (LLOs) have become the most promising cathode candidate for the next‐generation high‐energy‐density lithium‐ion batteries (LIBs). Unfortunately, the participation of oxygen anion in charge compensation causes lattice oxygen evolution and accompanying structural degradation, voltage decay, capacity attenuation,...

In article number 2301770, Yueliang Gu, Xiaochuan Ren, Daming Zhu, Jianxin Zou, and co‐workers elucidate the reaction mechanism of Mn2+ electrolyte additives in aqueous zinc batteries (ZIBs) via operando synchrotron X‐ray diffraction, ex situ X‐ray absorption spectroscopy and electrochemical analyses. A reversible Mn2+/MnO2 deposition/dissolution reaction occurred at the cathode,...
Aqueous zinc batteries (ZIBs) have attracted considerable attention in recent years because of their high safety and eco‐friendly features. Numerous studies have shown that adding Mn2+ salts to ZnSO4 electrolytes enhanced overall energy densities and extended the cycling life of Zn/MnO2 batteries. It is commonly believed that Mn2+ additives in the electrolyte inhibit the dissolution of MnO2 cathode...
Amination of aryl chlorides by metallaphotocatalysis is highly desired but remains practically challenging. Meanwhile, relying on soluble noble‐metal photocatalysts suffers from resource scarcity and structural instability which limit their practical application. Here in, a highly crystalline acetylene‐based hydrazone‐linked covalent organic framewok‐1 (AC‐COF‐1) is reported that enables metallaphotocatalytic...
The advancement in thermosensitive active hydrogels has opened promising opportunities to dynamic full‐thickness skin wound healing. However, conventional hydrogels lack breathability to avoid wound infection and cannot adapt to wounds with different shapes due to the isotropic contraction. Herein, a moisture‐adaptive fiber that rapidly absorbs wound tissue fluid and produces a large lengthwise contractile...
Although tremendous progress has recently been made in quasi‐2D perovskite light‐emitting diodes (PeLEDs), the performance of red PeLEDs emitting at ≈650–660 nm, which have wide prospects for application in photodynamic therapy, is still limited by an inefficient energy transfer process between the quasi‐2D perovskite layers. Herein, a symmetric molecule of 3,3′‐(9H‐fluorene‐9,9‐diyl)dipropanamide...

Tellurium (Te) is a promising electrode active material for potassium‐ion batteries due to its intrinsic electrical conductivity and ultra‐high theoretical volumetric capacity. Nevertheless, Te‐based electrodes usually exhibit low capacity at high rates and poor cycling stability caused by the large volume expansion and severe polytellurides dissolution. Herein, hierarchical porous carbon nanofibers...
Germanium (Ge)‐based devices are recognized as one of the most promising next‐generation technologies for extending Moore's law. However, one of the critical issues is Fermi‐level pinning (FLP) at the metal/n‐Ge interface, and the resulting large contact resistance seriously degrades their performance. The insertion of a thin layer is one main technique for FLP modulation; however, the contact resistance...
Recent years have witnessed the rapid development of sustainable materials.
