Gongye 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。

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 ...

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

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).

Gongye 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。

Mechanoluminescent Mixed‐Anion Borate Sr2B5O9Cl:Eu for Dynamic Anticounterfeiting
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Mechanoluminescence (ML)—the emission of light in response to mechanical stimuli—offers a direct and visually intuitive route for transducing mechanical information into optical signals. Herein, we report a mixed‐anion strategy to prepare mixed‐anion borate Sr2B5O9Cl:Eu phosphors through a facile, low‐temperature, and ambient‐atmosphere solid ...

, 2006 由高钛渣或钛铁矿为原料生产钛白粉或钛酸盐是重要的化工与冶金基础原料工业。目前国内外采用的硫酸法生产钛白传统工艺，工艺复杂，流程长，排放大量废酸、废水和废渣，环境污染极其严重；氯化法钛白工艺技术先进，但是，对原料要求苛刻，产生的废弃金属氯化物有毒，只能深井填埋。中国科学院过程工程研究所将亚熔盐清洁生产技术平台应用于钛资源的清洁转化，首次提出亚熔盐钛化合物清洁生产新工艺，以取代传统的钛盐和钛白粉生产方法。新工艺可大幅提高资源利用率，降低反应温度，并能实现资源有价组分的高效清洁利用 ...
