Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The immunosuppressive milieu of hepatocellular carcinoma (HCC) remains a major obstacle to durable antitumor responses. Mechanical‐energy‐driven piezocatalysis provides a noninvasive means of inducing oxidative damage and immunogenic tumor destruction; however, inefficient utilization of piezoinduced charges and insufficient localization of ...

Gongye shui chuli, 2009 采用南方高岭土(红壤)为原料合成FeS/高岭土片层复合材料,同时提出悬袋法天然水体污染治理工艺。初步探讨该复合材料在悬袋状况下对铅污染水体的吸附净化能力,实验表明在常温、中性、吸附时间60 min、复合材料投加质量分数为2%的条件下,可使被铅污染的水体中铅质量浓度从20 mg/L下降到0.25 mg/L,低于含铅废水工业排放标准。生物试验表明该复合材料无毒,可以作为天然水体重金属污染初步修复材料而与生物修复组合使用,以减少生物修复压力。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...
