Chloride Coordination‐Engineered Fe–NC Catalyst for Directed Singlet Oxygen Generation Through Peroxymonosulfate Activation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

High‐Performance Self‐Powered Ultraviolet Photodetector Based on NiO/La‐Doped SrSnO3/Nb‐Doped SrTiO3 Dual‐Heterojunction

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The development of high‐performance photodetectors critically relies on innovative interfacial band engineering, a strategy that enables the synergistic enhancement of photocurrent and drastic suppression of dark current. Herein, a self‐powered ultraviolet (UV) photodetector is demonstrated based on a NiO/La‐doped SrSnO3 (LSSO)/Nb‐doped SrTiO3

Efficient Spin‐Orbit Torques Enabled by Vanadium‐Induced Orbital Currents for Neuromorphic Computing

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Spin‐orbit torque (SOT) provides an efficient electrical pathway for encoding spin states and underpins emerging, ultrafast, and nonvolatile spintronic memories and logic devices. Reducing the switching current density and power consumption remains a central challenge for practical applications.

Beyond Photoreceptors: Bio‐Inspired Neuromorphic Vision System Mimicking Drosophila's Downstream Neural Circuitry With 2D β‐Ga2O3 Schottky Diodes

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...
