A Topology‐Guided Design Strategy for Polymerized Naphthoquinone Cathodes in Rechargeable Aluminium‐Ion Batteries

open access: yesRare 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 ...

FeCoNiCuPt High‐Entropy Alloy as a Robust Catalytic Shield Against Polysulfide Shuttling in Li–S Batteries

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Efficient catalytic materials are vital for addressing the polysulfide shuttle and sluggish redox kinetics in lithium–sulfur batteries. Herein, we report a facile sugar‐blowing method to prepare porous carbon‐supported FeCoNiCuPt high‐entropy alloy (HEA) nanospheres with abundant lattice defects in a single crystalline phase.

From Dendrite Accelerator to Suppressor: Engineering a Self‐Assembled Monolayer for Ultrafast and Dendrite‐Free Zinc Deposition

open access: yesRare 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.

含氨和硫酸盐废水的处理技术展望

open access: yesGongye 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。

MXene‐Based Materials Contribute Better Alkali Metal–Chalcogen Batteries: Progress, Challenges, and Perspectives

open access: yesRare 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 ...

天然气中微量总硫的快速测定法

open access: yes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 ...

富硫废水中稳定生物单质硫效果与机制研究

open access: yesGongye shui chuli
为提高含硫废水同步脱氮除硫工艺中生物单质硫回收率,开展了富硫废水中稳定生物单质硫效果与机制研究。在富硫废水(S2-质量浓度300 mg/L)和贫硫废水(S2-质量浓度200、100 mg/L)中添加阻断剂硫代硫酸钠进行脱氮除硫实验。结果表明,富硫废水中稳定组(加30 mg/L阻断剂)在60 h时单质硫积累量达到68.79 mg/L,比未稳定组(不添加阻断剂)高25.34 mg/L,单质硫稳定率达58.31%,单质硫回收率为36.84%;而贫硫废水(S2-质量浓度为200、100 mg/L)中单质硫不稳定,
