Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT To meet the escalating demand for high‐performance LiCoO2 (LCO) cathodes, elevating the charging cut‐off voltage becomes highly imperative to achieve markedly enhanced specific capacities. However, high‐voltage operation is always accompanied by structural instability, notably deleterious bulk phase transitions and severe interfacial ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

, 2016 为了解决砷污染的问题,研究了酸性条件下以臭氧做氧化剂氧化As(Ⅲ)的过程,考察了不同氧化剂、初始pH、反应温度和臭氧流量对As(Ⅲ)氧化效果的影响。结果表明,与空气相比,臭氧氧化As(Ⅲ)快速、高效;pH为1~5内,氧化速率随pH增大;在(23~53)℃内,由于臭氧溶解度降低,氧化速率随温度升高而降低,且在0℃时氧化速率很慢;在臭氧流量为90 mg/min以下时,氧化速率随臭氧通入速率的增加而增加。
