Charge‐Polarized Ni─S4 Single‐Atom Sites Drive Selective Photoreforming of Poly(lactic acid) to Lactate and Hydrogen

Advanced Functional Materials, EarlyView.
Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

Advanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...
