Gongye shui chuli, 2023 为解决TiO2光催化降解水体中萘普生时易团聚、低活性的问题，对P25 TiO2和石墨烯进行表面修饰，直接混合制得改进TiO2催化剂，随后将其用于光催化降解水体中的萘普生，并研究降解动力学、作用机制以及生物毒性。XRD、FTIR、SEM表征结果表明，TiO2经过修饰后引入了氨基，与改性石墨烯引入的含氧基团之间存在静电引力和化学键力，在这些力的作用下，TiO2较好地接枝在石墨烯的表面。暗吸附、生物毒性、催化和猝灭实验结果表明，在500 W氙灯光照条件下，依靠石墨烯的协助，TiO2在50 min内能将10 ...

Survival, rarity, and extinction in tropical stony corals
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Many reef‐building tropical corals are becoming rare. We considered the meaning of rarity in corals and highlighted taxa that have reached low abundances in the last few decades. The difficulties of quantifying rarity in the marine environment arise from the sheer scale and 3‐dimensional nature of the biome and the inherent challenges therein ...

In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐
