A study on the status of normoalbuminuric renal insufficiency among type 2 diabetes mellitus patients: A multicenter study based on a Chinese population 正常蛋白尿的2型糖尿病患者肾功能不全状况的研究:基于中国人群的多中心研究

open access: yesJournal of Diabetes, Volume 14, Issue 1, Page 15-25, January 2022., 2022
Highlights Approximately 63.6% of diabetes patients with an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 have normal albuminuria. The factors related to normoalbuminuria and eGFR < 60 mL/min/1.73 m2 were male sex, older age, higher triglyceride levels, lower extremity arterial disease, and a longer duration of diabetes. Compared with

垃圾渗滤液培养微藻研究进展:向碳中和迈进

open access: yesGongye shui chuli, 2022
高毒、高污染的垃圾渗滤液对自然水源造成了严重威胁,利用技术手段对其进行有效处理是解决环境问题的重中之重。采用垃圾渗滤液进行微藻培养,可以在实现垃圾渗滤液中碳、氮、磷高效去除的同时,提高微藻生物质产量并减少CO2排放量。然而,垃圾渗滤液高污染物含量、高浊度的特点决定了其必须经过一定的预处理才能够用于微藻培养。总结了垃圾渗滤液的特点,探讨了用于微藻培养的渗滤液的预处理方式及其存在的瓶颈,解析了利用垃圾渗滤液培养微藻所获得的生物质的用途 ...

混凝对微滤膜处理阴极电泳漆废水的影响

open access: yesGongye shui chuli, 2011
采用直接微滤和混凝—微滤两种工艺对阴极电泳漆废水进行处理。结果表明:混凝预处理减轻了膜污染,提高了膜的渗透通量;当膜面流速为4 m/s,跨膜压差为0.10 MPa,温度为30℃时,稳定通量从直接微滤的47.8L/(m2.h)提高到264.2 L/(m2.h),远高于超滤膜的通量。与原水直接微滤相比,混凝—微滤组合工艺改善了出水水质,CODCr去除率从67%提高到85%,磷酸盐去除率从37%提高到98%。有效清洗后,膜通量可恢复到初始值的84%。

Sustainable Nanocellulose‐Based Materials for Environmental Remediation: Structure–Function Relationships and Applications

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Environmental pollution across water, air, and soil systems poses escalating threats to human health and ecosystem stability, driven by heavy metals, persistent organic pollutants, particulate matter (PM), bioaerosols, and toxic gases. Conventional remediation technologies often suffer from limited selectivity, insufficient efficiency, and the

Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

反渗透预处理系统微生物污染原因分析及处理

open access: yesGongye shui chuli, 2016
反渗透保安过滤器滤芯出现频繁污堵现象,通过系统调查、电镜扫描及能普仪检测,确认滤芯被微生物污堵,在预处理系统其他设备也存在微生物污染。预处理阶段杀生剂使用不足、系统经常长时间停运以及工艺流程不合理是导致微生物污染的主要原因。提出对预处理系统全面消毒,清洗被污染过滤器滤料,提高杀菌剂用量并加强水质监测,活性炭过滤后增加二次杀菌点等治理和防控微生物污染的措施。
