Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Solar‐blind ultraviolet (UV) photodetectors (SBPDs) play a critical role in applications including UV communication and fire warning systems. Gallium oxide (Ga2O3) has emerged as a promising material due to its wide bandgap and low cost, but suffers from high dark current and slow response speed caused by oxygen vacancy (VO) defects.

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Laser powder bed fusion (LPBF) of Inconel 718 alloy inevitably introduces pronounced microstructural anisotropy, typified by columnar grains and robust crystallographic texture. This results in direction‐dependent fatigue behavior, raising critical reliability concerns for high‐stakes aerospace applications.

染色体核型分析联合快速MLPA非整倍体技术在产前诊断中的应用
Zhongguo shiyan zhenduanxue, 2020 染色体核型分析技术是检查人类染色体金标准方法,但染色体核型分析技术要细胞培养,检测时间长,操作程序复杂,技术要求高,2002年荷兰White和Schouten创建了多重链接依赖性探针扩增技术（MLPA）[1-3],MLPA不用细胞培养,是一种快速简单的检测方法。为了探讨染色体核型分析联合MLPA非整倍体技术在产前诊断中的应用价值,对2000例有产前诊断指征孕妇羊水,分别采用染色体核型分析和MLPA非整倍体技术检查,结果总结如下。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Reliable monitoring of ultraviolet (UV) radiation is critical for protecting human health, yet existing sensors often rely on costly or rigid components that hinder portability. Here we report a wearable, low‐cost colorimetric sensor for quantitative UV dosimetry, enabled by radical‐triggered aggregation of gold nanoparticles (AuNPs).
