Gongye shui chuli, 2012 对给水处理中活性炭吸附水中有机物的性能筛选指标进行研究，由于测定活性炭焦糖脱色率时所用焦糖的分子质量分布与天然水中有机物的分子质量分布相似，故提出用焦糖脱色率评价给水处理用活性炭的吸附性能。经试验证实，以焦糖脱色率评价活性炭吸附性能的试验结果与DL/T582—2004（以腐殖酸、富里酸、木质素、丹宁进行评价）的结果相同。建议用于给水处理的活性炭焦糖脱色率＞50%。

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...

Gongye shui chuli, 2015 采用60Coγ射线辐照预处理城市污水处理厂剩余污泥, 通过污泥比阻的变化, 研究了辐照中污泥pH、辐照剂量以及曝气处理对污泥脱水性能的影响。结果表明:在γ辐照预处理中, 当pH为7左右时, 污泥比阻最低, 污泥脱水性能最佳;随着辐照剂量的升高, 污泥中可溶性有机组分和氨氮含量逐渐增大, 污泥比阻降低, 污泥脱水性能随之改善;经曝气处理后进行辐照, 能进一步降低污泥比阻, 显着改善污泥脱水性能。污泥比阻的变化服从一级反应动力学方程。

World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT This article examines how renewable‐energy expansion is changing water–energy bargaining among Iran, Iraq, and Türkiye in the Tigris–Euphrates basin. Much of the existing literature on transboundary water politics focuses on territorial control, upstream–downstream power asymmetries, legal rules, and hydro‐hegemony but gives less attention to ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Biomass‐based hydrogels are widely regarded as ideal substrates for self‐powered wearable sensors. However, the practical applications of hydrogels are commonly limited by their inherent low strength and toughness, which restrict their capacity to withstand repeated stretching, bending and other mechanical loads arising from human motion in ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

VO2 Hollow Nano‐Reactor: Enabling Near‐Room‐Temperature and Ultrafast Hydrogen Release From α‐AlH3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT α‐phase aluminum trihydride (α‐AlH3) is a promising high‐capacity hydrogen storage material, but its practical application is limited by slow dehydrogenation kinetics and high reaction temperatures. This study demonstrates, for the first time, effective modulation of the hydrogen release kinetics of AlH3 by employing a hollow nanostructured ...

Gaoya dianqi, 2022 环氧树脂由于其优异的绝缘密封性能被广泛应用于干式空心电抗器，然而在湿热环境中环氧树脂易吸水受潮导致材料性能劣化，严重影响设备的安全稳定运行，掌握材料的吸水与脱水行为对其实际应用具有重要意义，因此文中研究了环氧树脂在不同酸碱盐溶液中的吸水与脱水特性。实验结果表明：环氧树脂在不同溶液中的吸水过程符合菲克第二定律；吸水速率和饱和吸水率与两侧溶液浓度差有关，环氧树脂在去离子水中的吸水速率最大；脱水过程也是一种渗透作用，环氧树脂脱水速率很快，相对平衡脱水率几乎能达到100%。

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
