Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

, 2019 文中对顺丁橡胶进行热氧老化研究,采用核磁共振氢谱、傅里叶变换衰减全反射红外光谱、紫外-可见光吸收光谱法3种谱学法对老化产物进行表征。追踪顺丁橡胶在老化过程中化学结构的变化,进而探究其老化机理。结果表明,顺丁橡胶的抗热氧老化能力较差,在120℃老化0.5 d时,其结构即发生明显变化,烯烃含量明显下降,生成醇及醛酮化合物,老化15 d时顺丁橡胶双键α-H已反应约97%。热氧老化反应机理为双键α-H先发生氧化形成过氧化羟基,进而氧化成醇及醛酮化合物,最终降解生成末端丙烯醛,同时双键发生自由基加成反应 ...

Aging characteristic investigation of VLEDs with current blocking layer structure [PDF]
, 2015 发现ICP dAMAgE制作电流阻挡层的制程会导致垂直结构lEd在老化过程中发生漏电。通过更换反射层的金属及EMMI&SEM分析,发现老化漏电的原因来源于反射金属——Ag的电迁移,迁移通道可能来源于ICP打开穿透位错的封口。在缺陷位错内填入低电迁移率金属并检测。结果表明,填入低电迁移率金属后既解决了老化漏电问题,同时不影响芯片的初始光电特性。The failure of current leakage in the process of ICP-damage current blocking layer

Integrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.
