Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Due to their exceptional porosity, structural versatility, and modular coordination chemistry, metal–organic frameworks (MOFs) have emerged as versatile platforms for targeted drug delivery. These structures enable fine‐tuning of pore size, surface activity, and framework stability for the encapsulation of a broad range of therapeutics ...

Magnetization Dynamics Control for Noise Reduction in Fluxgate Sensors
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Fluxgate sensors are indispensable for the detection of weak magnetic fields. However, their noise performance remains constrained by an incomplete understanding of the interplay between the high‐frequency magnetization dynamics of the core material and the overall sensor behavior.

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

四川大学学报. 自然科学版, 2005 以产气量为指标测试了10种邻苯二甲酸酯的厌氧生物降解性状,发现随分子结构的变化,其厌氧终极降解速率和降解半衰期表现出较大差异,厌氧生物降解难易程度依次为:DMP=DEP>DnPP>DnBP>DnAP>>DiHPDUP;将分子结构参数与降解速率、半衰期用SPSS进行多元回归分析表明邻苯二甲酸酯的分子结构是决定其厌氧生物降解性的关键因素,高分子量的化合物不利于厌氧生物降解.研究结果对其厌氧生物处理、生物修复具有一定的理论指导意义.

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Gongye shui chuli, 2018 研究了UV/Oxone（KHSO5·0.5KHSO4·0.5K2SO4）降解氧氟沙星（OFL）的动力学和机理。考察了OFL初始浓度、Oxone投加量、腐殖酸、氯离子、硝酸根等对OFL降解的影响。结果表明，UV/Oxone体系降解OFL的过程符合准一级反应动力学方程，OFL的降解速率随OFL初始浓度的增加而减小，随Oxone投加量的增加而增大。腐殖酸、氯离子、硝酸根等均不同程度地抑制了OFL的降解。用液相色谱-高分辨质谱联用仪分析OFL的6种降解产物，推测其主要降解途径是脱甲基和开环作用。

Journal of Ecology, Volume 114, Issue 8, August 2026.Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Gongye shui chuli, 2019 以石墨碳毡为阳极，采用氧气-阳极协同氧化法对亚甲基蓝（MB）、结晶紫（CV）和罗丹明B（RhB）进行降解，研究了不同电压下染料的降解动力学和降解途径。结果表明，染料在降解初期符合一级动力学特征，且其降解速率随电压的升高而加快。1.8、2.0 V电压下，MB和CV在12 h内脱色率达到100%，而RhB在3 h内脱色完全。染料在体系中主要通过N-去甲基化/去乙基化和发色团解离途径被部分降解。
