NaCl盐度对吡啶缺氧反硝化降解的影响

open access: yesGongye shui chuli, 2016
采用批量实验研究NaCl盐度对常规活性污泥(非耐盐污泥)缺氧反硝化降解吡啶的影响。结果表明,吡啶降解受到盐度的影响,在盐度为5.0 g/L时,降解率最高。硝酸盐氮在盐浓度为2.5 g/L时,降解率可达85%,当盐度大于10.0 g/L时,氨氮浓度呈上升趋势,高盐度使微生物结构发生破坏是氨氮浓度升高的原因;在不同盐度条件下,总氮降解浓度会发生变化,在盐度为2.5 g/L时,总氮降解率最高。

Land use overrides climatic controls on soil organic nitrogen transformations: Contrasting responsiveness between forest and cropland ecosystems

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2128-2142, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil organic nitrogen (SON) transformation is critical for global nutrient cycling and ecosystem productivity, yet how its responsiveness to climate change differs across diverse land use types remains poorly resolved.

The vesicle trafficking R‐SNARE VAMP714 connects auxin responses, ROS and ion homeostasis in Arabidopsis under salt stress

open access: yesNew Phytologist, Volume 251, Issue 1, Page 207-227, July 2026.
Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

高铁酸钾处理多晶硅废水影响因素研究

open access: yesGongye shui chuli, 2016
采用高铁酸钾处理多晶硅废水,考察了初始pH、高铁酸钾投加量和反应时间对污染物去除效果的影响。结果表明,高铁酸钾通过氧化和絮凝作用去除污染物。初始pH为4时,高铁酸盐对COD和浊度的去除率最高,初始pH在5以下时高铁酸盐除F-效果好;初始pH为4、最佳投加量为500 mg/L情况下,高铁酸盐对COD的去除率达到43.4%。纳滤分析表明高铁酸盐氧化能使聚乙二醇断链降聚,改善了多晶硅废水的可生化性。

Multiscale Simulation‐Driven Micro‐Bubble Bottom‐Blowing Electrolysis Toward High‐Efficiency Titanium Scrap Recycling

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The large‐scale application of titanium is limited by its high production costs, as well as its low utilization and recycling rates. Therefore, efficient recovery of titanium scrap offers a viable pathway to reduce its cost. Molten‐salt electrolysis offers a promising route for upcycling titanium scrap, but the conventional method, which ...
