Application of rhodamin-based acid sensitive fluorescent probe in cell biology and tumor diagnosis [PDF]
, 2016 荧光分子探针具有特异性、专一性、灵敏性、快速便捷以及可视化等优点，近年来逐渐在环境监测、生命科学研究、医学诊断等领域得到重视。尤其是在生物医学领域，人们对于应用荧光探针来检测细胞内环境的变化以及实现肿瘤的可视化诊断越来越有兴趣。细胞内或肿瘤内环境具有特殊的性质，如溶酶体的pH要比其他细胞内囊泡的pH更低，肿瘤的pH比正常组织更低。利用这一性质可以为肿瘤的早期诊断提供思路。本文总结了现有的研究成果，设计了新的酸敏感的荧光分子探针R6G-EDA，基于该探针设计了一系列测定胞内酸度的纳米颗粒 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Shuitu Baochi Xuebao, 2007 研究了深圳市1991～2004年的酸雨时空分布、降雨化学组成及其成因分析。结果表明，深圳市酸雨14年间pH平均值为4．98，酸雨频率为44．2％；降雨中SO4^2-与NO3^-比值是3．78：1，低于全国平均值6.4；酸雨夏秋两季较为严重，主要集中在3～9月份，而冬春两季降雨酸度和酸雨频率均较小；酸雨强度由西向东依次减弱；降雨中离子来源主要是工业和交通排放的酸性污染物，但陆地源和海洋源对降雨酸度的影响也较大。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Ni3S2 has emerged as a promising catalyst for the electrochemical oxidation of biomass‐derived 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA), driven by its distinctive physicochemical properties. However, its practical catalytic efficiency is severely hindered by abundant electrochemically inactive surface sites and poor ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).
