Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Sb2S3 is regarded as a promising anode for sodium‐ion batteries (SIBs) because of its high theoretical capacity and moderate working potential. However, it suffers from huge volume changes, poor conductivity, and excessive side reactions, leading to severe capacity decay and a low initial Coulombic efficiency (ICE), thus limiting its practical

, 2009 生物同质化是指特定时间段内两个或多个生物区在生物组成和功能上的趋同化过程, 包括遗传同质化、种类组成同质化和功能同质化三个方面.近年来, 生物同质化问题已引起生态学界的高度重视, 成为保护生物地理学的一个全新议题, 但在国内的相关研究较少.本文从生物同质化概念的发展历程入手, 对生物同质化三个方面的度量方法和驱动因素分别做了介绍和评述, 指出外来物种入侵和本土物种灭绝是导致生物同质化的最主要原因, 其他能促进这两个过程的活动, 如环境退化和干扰、城市化和生境同质化等都会对生物同质化有影响 ...

生物质炭和果胶对再生水灌溉下玉米生长及养分、重金属迁移的影响
Shuitu Baochi Xuebao, 2017 利用根箱试验方法比较了生物质炭和果胶对再生水灌溉下土壤—植物系统养分和重金属迁移特征的影响及差异性。结果表明，再生水灌溉不利于植物的生长，果胶和生物质炭两个处理相比，虽然植株生长无显著差异，但果胶处理植株的生长状况优于生物质炭处理；再生水灌溉时，果胶处理地上部生物量比对照增加了59.32%。与蒸馏水灌溉相比，再生水灌溉增加了根际土壤pH；灌溉水源相同时，果胶处理根际土壤pH略低于生物质炭处理。生物质炭和果胶都增加了土壤养分的含量，果胶对土壤碱解氮、有效磷和有机质的增加效果优于生物质炭 ...

Zhejiang Daxue xuebao. Lixue ban, 2012 采用氧化铁/醋酸纤维复合膜(FeO/CAM)法研究厦门湖边水库水体和沉积物中生物有效磷浓度的空间分布特征，分析生物有效磷及不同类群微藻叶绿素a质量浓度之间的相关性，初步探讨生物有效磷的来源.结果表明，表层水中生物有效磷质量浓度(FeO-P)低于底层水，且均以颗粒态生物有效磷(FeO-PP)为主.表层水中生物有效磷质量浓度在南部湖湾较高；而底层水中生物有效磷质量浓度则在开阔区域较高；沉积物中生物有效磷在入水口最高.各种生物有效磷与各类群藻叶绿素a质量浓度之间表现不同的相关性.除表层水中FeO ...
