O2−/F− Anion Co‐Migration Enabled Regulation of Grain Boundary Structure for Lower Impedance in Li0.32La0.56Fe0.01Ti0.94Sb0.06O3 Solid Electrolyte

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Microstructural characterization of Li0.32La0.56Fe0.01Ti0.94Sb0.06O3 (LLFeTSO) using AC‐TEM revealed that Fe3+/Sb3+ ion co‐doping induces the migration of lattice oxygen to grain boundaries (GBs), enhancing GB conductivity. However, the atomic arrangement at the GBs remains highly ordered and lacks sufficient cation vacancy carriers.

Nonequilibrium Precipitation Pathway Enabling Direct δ‐phase Formation and Enhanced Cryogenic Strength–Ductility in an Additively Manufactured Multi‐Principal‐Element Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.

基于生态过程与景观生态背景值的区域生态压力研究

Shuitu Baochi Xuebao, 2006
目前常用的数学模型法和景观生态学方法，对揭示区域生态压力的现状和进行区域横向比较具有良好效果，但是缺乏历史纵向比较。景观生态背景值，是在综合了区域特定历史时期景观生态本底值和合理的人类活动两方面因素的基础上形成的。运用景观生态背景值作为景观生态压力评价的坐标起点，结合区域中主要的生态过程，通过对变化中的景观生态类型、格局与景观生态背景值的偏离程度来评价区域生态压力与安全，评价结果不仅能较明确地说明区域生态压力与安全现状的性质，同时清晰地揭示出人为因素对区域生态压力与安全状态的影响程度与性质。

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

Bias‐Gated Functional Switching on Ti3C2/Cu2O/Au@Ag Heterostructure‐Based Photoelectrochemical Platform: OFF–ON Signal Transduction Detection and Efficient Degradation of Ciprofloxacin

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT A central challenge in high‐performance photoelectrochemical (PEC) systems is mitigating the intrinsic limitations in photogenerated carrier separation and transport, while enabling efficient broad‐spectrum solar harvesting. Inspired by the synergistic effect between plasmonic resonance and heterojunction built‐in electric fields, a ternary ...

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

Rare 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.
