A crystal‐phase transformation strategy constructs a MnOOH/α‐MnO2 composite featuring intertwined nanowire and nanorod architectures for high‐performance aqueous zinc‐ion batteries. The composite cathode delivers an exceptional balance of high specific capacity and ultralong cycling stability, maintaining 233.4 mAh g−1 over 750 cycles at 1 A g−1 and 85.

Impact of Nickel Diffusion on Leakage Current Degradation in β‐Ga2O3 Schottky Barrier Diodes
The diffusion of Ni atoms during Schottky electrode fabrication induces localized stress defects in β‐Ga₂O₃ substrates, which act as primary reverse leakage pathways in SBDs. Elucidating this mechanism provides critical guidance for optimizing electrode composition in high‐performance β‐Ga₂O₃ electronics.

ABSTRACT Intracerebral hemorrhage (ICH) is a life‐threatening stroke subtype that lacks effective drug therapy. In the context of ICH, neuroinflammation, and ferroptosis are key contributors to secondary brain injury. In this study, we assessed the neuroprotective effects of matrine (MAT) and its mechanism of action involving the HMGB1/RAGE axis in an ...

Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.
