四川大学学报. 自然科学版, 2012 基于长江、嘉陵江重庆主城段不同粒径表层沉积物样品,进行了粘土矿物（高岭石、蒙脱石）掺混前后对典型多环芳烃荧蒽的吸附特性研究,试验结果表明,荧蒽的吸附能力与表层沉积物粒径大小具有一定的相关性;沉积物粒径越小,其吸附能力相对越强.不同粒径的表层沉积物对荧蒽的等温吸附曲线表明,对于相同的液相平衡浓度,固相吸附量大小依次为320目>240目>120目.沉积物样品中粘土矿物的掺混可显著增强其对荧蒽的吸附能力,且蒙脱石优于高岭石,这是由于不同粘土矿物晶型构成存在差异.沉积物样品对荧蒽分配特性的分析结果表明 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Shuitu Baochi Xuebao, 2008 研究了三江平原3种土地利用方式下沟渠沉积物DOC含量和分布,探讨了3种土地利用方式对沟渠沉积物DOC含量和分布的影响。结果表明,三江平原沟渠系统虽然都是在湿地的基础上开挖而成,但是分散于3种土地利用方式下的沟渠沉积物DOC含量及其分布发生了明显变化。湿地开垦为农田利于沟渠各层沉积物DOC的累积,水田和旱田相比,旱田更有利于沟渠各层沉积物DOC的累积;沟渠沉积物DOC垂直分布随土地利用方式不同发生了明显的变化,穿过型沟渠和边界沟渠相比,边界沟渠沉积物DOC垂直分布显示出更强的沉积特点 ...

Shuitu Baochi Xuebao, 2007 以南湖水体中的水、表层沉积物、生物膜和悬浮物为研究对象,对美国EPA规定的16种优控PAHs中13种PAHs的分布与富集特征进行了研究。结果表明,表层沉积物中检出12种PAHs,生物膜和水相中均检出11种PAHs,而悬浮物中只检出7种PAHs;生物膜和悬浮物富集PAHs的能力相近,比表层沉积物的富集能力大一个数量级;相关分析表明,生物膜和悬浮物富集PAHs的能力归因于其有机质（TOC）的含量高于表层沉积物中有机质的含量。根据菲/蒽比值和PAHs环数相对丰度对南湖表层沉积物中PAHs的来源进行了分析 ...

Shuitu Baochi Xuebao, 2006 腐殖酸作为湖泊沉积物中有机质的主要成分．对重金属具有强烈的富集能力，从而影响湖泊沉积物中重金属向水中的释放。本文深入探讨了腐殖酸的不同组分对沉积物中Cu、Zn、Pb、Cd向水中释放的影响。结果表明：腐殖酸的添加使沉积物中重金属的释放置明显受到影响。Cu、Zn、Pb、CA4种重金属随着胡敏酸和富里酸的添加．释放量逐渐增加，并且两种腐殖酸的用量越大．重金属的释放量越大。向沉积物中加入同等量的胡敏酸、富里酸，两种腐殖酸对重金属释放的促进作用胡敏酸〉富里酸。向沉积物中加入不同用量的富里酸FA，沉积物中Cu、Zn、

Gallium‐Doped α‐MnO2 Cathode for High‐Performance Aqueous Zinc‐Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Rechargeable aqueous zinc‐ion batteries (ZIBs) have received significant attention because of their high safety and low cost. MnO2 as a cathode material hampers the application of ZIBs due to its structural instability and dissolution during the operation of the battery.
