Visible‐Light‐Excited Optical Thermometry in Ca3Sc2Si3O12: Er3+ via an Efficient Eu2+ Bridge

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Er3+ ions are promising for optical thermometry due to their thermally coupled levels. However, their parity‐forbidden transitions result in weak and narrowband absorption, which restricts excitation to infrared lasers (e.g., 808, 980, or 1550 nm). Moreover, the single emission center inherently limits temperature sensitivity. In this work, we

Transfer Learning‐Guided Discovery of Advanced Tetrametallic Single‐Cluster Catalysts for Urea Electrosynthesis

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Developing advanced electrocatalysts for urea synthesis is pivotal to alleviating environmental burdens as well as advancing sustainability in the industrial and agricultural sectors, yet untargeted catalyst screening still suffers from the notorious drawbacks of being time‐consuming, labor‐intensive, and inefficient.

Microwave‐Actuated CuS/CuCo2O4 Heterojunction Microneedles for Synergistic Eradication of Deep‐Seated Biofilms and Inflammatory Microenvironment Remodeling in Acne Treatment

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Deep skin infections and dense biofilm barriers caused by Propionibacterium acnes (P. acnes) remain significant challenges in recurrent acne vulgaris, exacerbated by the poor stratum corneum penetration of conventional therapies and rising antibiotic resistance.

An Organo‐Pt(II) Photosensitizer With Robust Photo‐Assisted Antibacterial and Wound Recovery Performances in Diabetic Mice Wound Model

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The pathogenesis of diabetic foot ulcers is complex, often involving polymicrobial infection and persistent inflammatory responses, which lead to delayed or nonhealing wounds, posing a formidable clinical challenge. Existing photodynamic therapy reagents and traditional treatments generally address only a single pathological aspect, and the ...

Synergistic Dual‐Defect Engineering in Amorphous‐Nanocrystalline Heterostructures for Accelerated Oxygen Evolution

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Defect engineering has been widely demonstrated as an effective strategy for enhancing the activity of OER metal catalysts, among which the introduction of twin boundaries (TBs) has proven particularly efficient. However, single‐type defects offer limited performance enhancement.

Assessing Gray Zone Risks in East Asia: A Threat Classification Framework Using Taiwan's ADIZ as a Case Study

Asian Politics &Policy, Volume 18, Issue 3, July 2026.
ABSTRACT Gray‐zone activities have become a central feature of security competition in East Asia, particularly in the Taiwan Strait, where persistent military operations blur the boundary between coercion and armed conflict. This study develops a structured threat‐assessment framework for evaluating the intensity of PLA aerial gray‐zone pressure around

Designing Additive‐Manufactured High‐Performance CoCrNi Matrix Composites Based on Grain Boundary Segregation

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Through grain boundary segregation engineering, a crack‐free high‐strength CoCrNi medium‐entropy alloy (MEA) can be successfully fabricated via laser powder bed fusion (PBF‐LB). The influence of micron‐sized TiC particles on microstructural evolution, grain boundary segregation behavior, and mechanical properties was systematically ...

Dual‐Phosphidation‐Engineered Ni/NiO Heterojunction Nanoflowers With Synergistic Surface PO43− Group and P Doping Sites for High‐Performance and Low Temperature (−40°C) Supercapacitors

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Nickel oxide (NiO)‐based electrodes with high theoretical specific capacitance can effectively increase the energy density of supercapacitors—the key factor limiting their practical deployment. However, several issues still restrict the production of advanced NiO‐based electrodes.

Harnessing social media data to track species range shifts

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

自然和人工模拟降雨条件下紫色土坡地的磷素迁移

Shuitu Baochi Xuebao, 2006
采用人工降雨和自然降雨的方法对紫色土坡地磷素迁移进行比较研究。研究结果表明：紫色土坡地产生地表径流和壤中流两种径流模式，壤中流其径流动态过程受降雨强度和表层作物覆盖度的影响；持续性变化的大雨强更容易引起土壤磷非点源输出，导致水体富营养化；在中到暴雨条件下，壤中流累积迁移流量低于地表径流，差幅决定于土壤表层界面（植被覆盖）特征，地表径流中的磷迁移量是壤中流迁移的3～4倍。
