Lignin‐Derived Carbon Quantum Dots as Hole‐Trapping Promoters in LCDs/Bi‐MOF/ZIS With S‐Scheme Heterojunction for Efficient Photocatalytic Hydrogen Peroxide Production in Pure Water

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

Enhanced Energy Storage Performances of Ceramics Enabled by Local Lattice Disorder Based on High‐Entropy Strategy

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT With the depletion of energy resources and the vigorous development of renewable energy technologies, the demand for efficient energy storage technologies has become increasingly urgent. Dielectric ceramics feature ultrafast charge–discharge speed, but low energy density and inferior efficiency hinder device miniaturization.

Tailoring the Mechanical Properties of L‐DED‐Fabricated γ‐TiAl Alloys Through Heat Treatment: Correlating Microstructural Evolution With Fracture Mechanisms

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments.

特高压电容分压器宽频无源等效电路建模方法

open access: yesGaoya dianqi, 2017
为了提高特高压电容式电压互感器的瞬态性能,分析其在较宽频域内的分压特性,以某公司生产的1 000 kV特高压电容分压器为实验对象,进行了特高压电容分压器阻抗的测量,建立了特高压电容分压器的宽频等效电路模型。首先,测量特高压电容分压器的阻抗;其次,基于测量得到的数据结合矢量匹配法和电路综合理论,建立了特高压电容分压器的宽频等效电路模型,并利用模式搜索算法对等效电路进行无源修正;最后,利用所建立的模型,分析特高压电容分压器在不同频率下的分压特性,为合理设置均压装置以及改善特高压的制造工艺提供理论依据。

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...
