Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In this work, In2O3 and three rare earth (RE)‐doped In2O3 composites (Ho, Yb, and Sm‐doped) were prepared via the hydrothermal method. Compared with In2O3 sensors, those fabricated from the three composite materials (RE–In2O3) exhibit varying degrees of enhanced response toward ethylene glycol (EG) gas. At 35% relative humidity (RH) and 250°C,

四川大学学报. 自然科学版, 1992 研究了栗黄枯叶蛾核型多角体病毒(Trabala vishnou Nuclear PolyhedrosisVirus)的病毒粒子蛋白(Virion Protein),简称TV—NPV—VP,在不同pH值条件下于银胶中的表面增强拉曼光谱.将TV—NPV—VP在中pH值的表面增强拉曼光谱(SER谱)与它的一般拉曼光谱(OR谱)作了比较分析。样品在不同pH值条件的SER谱反映了其不同的吸附特征,说明分子的表面几何状态随pH值的不同而改变.TV—NPV—VP和银胶表面的吸附主要是化学吸附.增强机理具有短程特征.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.

低pH值对大型溞（Daphnia magna Straus）存活、生长和生殖的影响
, 1994 在静置换水条件下，研究了低ｐＨ值对大型存活、生长和生殖的影响。结果表明，在２５±１℃下，急性试验低ｐＨ值对大型的２４ｈ和４８ｈＬＬ５０值及其９５％可信限分别为ｐＨ值４．６６±０．１９和４．９４±０．２０。慢性试验进行了１４天，对存活和生长，ｐＨ值１．７５有影响，ｐＨ值５．０没有影响；对生殖，ｐＨ值５．０有影响，ｐＨ值５．５没有影响。显示出低ｐＨ值对大型的毒性阈限在ｐＨ值５．００－５ ...
