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 ...

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Shuitu Baochi Xuebao, 2011 湿地是灌区农业面源污染物的汇集地,沉积物中的营养盐和重金属含量是指示水体营养状况的地球化学指标之一.该文分析了宁夏黄灌区湿地沉积物剖面中TOC、TN、TP、Zn、Cu含量的垂向分布特征,并与湿地周用农田、排水沟和猪场排污口沉积物相应层次元素的含量进行了比较.结果表明,湿地沉积物剖面中TOC、TN垂向分布规律相似,在0-50cm有富集,湿地沉积物中TOC的含量是农田和排水沟的5～7倍、是猪场排污口的2.4倍,湿地沉积物中TN的含量是农田和排水沟的3倍左右,是猪场排污口的1.24倍 ...

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 7, July 2026.ABSTRACT Biodegradable zinc (Zn)‐based materials are considered promising candidates for orthopedic applications because of their favorable mechanical properties, controllable biodegradability, and good biosafety profiles. However, their clinical translation is limited by early‐stage corrosion‐induced cytotoxicity and inflammation, as well as ...

Shuitu Baochi Xuebao, 2017 应用SMT连续提取法对连环湖敖包泡北部（AB1）和南部（AB2）柱状沉积岩芯中磷形态的含量和垂向分布特征进行对比分析，结合沉积岩芯年代测定，探讨了该湖区沉积物中磷的演化特征与人为污染历史以及内源磷的释放风险。结果表明，AB1、AB2沉积物中磷形态的含量和垂向变化不同，AB1沉积物中各形态磷含量均高于AB2，且随深度变化波动较大。20世纪40年代中期至1981年，AB1沉积物各形态磷和OM含量波动较大；AB2沉积物中Ca-P、IP、TP含量呈先增加后减少之势，Fe/Al-P、OP、OM含量变化较稳定 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Defect engineering has been widely demonstrated as an effective strategy for enhancing the activity of OER metal catalysts, among which the introduction of twin boundaries (TBs) has proven particularly efficient. However, single‐type defects offer limited performance enhancement.
