Facile and Efficient Synthesis of Dual‐Defect NiFe Layered Double Hydroxides for Enhanced Oxygen Evolution Reaction

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Electric Field‐Induced Dark Current Steering in MAPbI3/Nb2CTx Photodetector Toward Weak‐Light Single‐Pixel Imaging

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This

绿肥间作对渭北果园土壤水分、养分及苹果产量的影响

Shuitu Baochi Xuebao
目的研究渭北苹果园不同种类绿肥间作及其结合地布覆盖在土壤蓄水保墒、养分供给和果实产量提升方面的效应。方法设置黑麦草（R）、油菜（O）、苜蓿（A）3种绿肥和不覆地布（NG）、覆盖地布（G）2种覆盖方式，以清耕为对照（CK）。不覆地布+绿肥间作为主处理，覆盖地布+绿肥间作为副处理。在主处理和对照各小区分别设置15N田间示踪微区。探究苹果-绿肥间作系统土壤水分、养分及果实产量的响应。结果各处理土壤质量含水率均低于CK处理，GR处理下降幅度最小（1.7%）。主处理土壤水分差异率均为负值，其中NGR处理绝对值最低（

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

Rare 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 ...

Interstitial Pt–Pd Bimetallic Sites Enable Cooperative Intermediate Regulation for Methanol‐Assisted Hydrogen Generation

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Methanol‐assisted hydrogen generation reduces energy consumption while maintaining high hydrogen productivity. However, constructing bifunctional catalysts with high hydrogen evolution reaction (HER) activity, CO tolerance, and long‐term stability remains challenging.
