Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Rechargeable aluminium‐ion batteries (RAIBs) are promising candidates for sustainable energy storage owing to their low cost, safety, and resource abundance. However, the lack of durable cathode materials restricts their development. Here, we propose a topology‐guided design strategy by synthesizing three thioether‐bridged naphthoquinone ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Gongye shui chuli, 2012 目前许多废水不仅含有高浓度的氨氮,而且含有高浓度的硫酸盐,给废水治理带来难度。对同步脱硫反硝化工艺和硫酸盐型厌氧氨氧化工艺的研究进展进行了综述。同步脱硫反硝化工艺和硫酸盐型厌氧氨氧化工艺能同时脱氮和除硫,不仅无H2S排放,而且还具有节约碳源、污泥产量小和实现单质硫回收的优点。其中硫酸盐型厌氧氨氧化工艺无需曝气和有机物,具有更高的技术和经济优势,将是未来生物脱氮除硫技术的新方向。

四川大学学报. 自然科学版, 1980 前言天然气中含有少量的有机硫与无机硫.其有机硫的基本组分多半为低沸点的硫醇、硫茂、气态的硫羰和二硫化碳.无机硫主要是硫化氢与二氧化硫.由于天然气在井中,因温度高,各组分均有可能存在,但经过输气管配气后,将有一部冷凝,一部分则以蒸气状态残留,故含量较微。此等硫化物在天然气催化过程中,常引起催化剂中毒,因此生产控制要求测定总硫量.据文献介绍气体中总硫量的测定,常用燃烧一氧化法与燃烧一氢化法 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Alkali metal–chalcogen batteries (AMCBs) are one of the most promising next‐generation energy storage systems because of their high energy density and reasonably low cost. However, the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode, the shuttle effect of polychalcogenides, and unstable ...
