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).

Gaoya dianqi, 2015 套管故障率往往高于变压器本体,准确评估套管健康状态对提高变压器整体运行可靠性十分重要。文中基于物元分析理论提出了套管健康状态的评估方法。以试验检测数据为基础,综合考虑巡视检查与维护历史状态参量,构建了套管健康状态评估的层次型指标体系;采用层次分析法（AHP法）确定指标初始权重,并根据指标数据变化量、利用信息熵对试验类指标的初始权重进行修正。基于物元理论构建了套管健康状态的评估物元,考虑到定量指标测量干扰及定性指标主观判断所带来的误差,采用一个数据区间来表征指标状态 ...
