Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Methanol‐assisted hydrogen generation reduces energy consumption while maintaining high hydrogen productivity. However, constructing bifunctional catalysts with high hydrogen evolution reaction (HER) activity, CO tolerance, and long‐term stability remains challenging.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT The pathogenesis of diabetic foot ulcers is complex, often involving polymicrobial infection and persistent inflammatory responses, which lead to delayed or nonhealing wounds, posing a formidable clinical challenge. Existing photodynamic therapy reagents and traditional treatments generally address only a single pathological aspect, and the ...

不同剂量丙泊酚靶控输注对体外循环心脏手术病人细胞因子TNF-α、IL-10mRNA表达的影响
Zhongguo shiyan zhenduanxue, 2012 目的观察不同剂量丙泊酚靶控输注对体外循环心脏手术病人细胞因子TNF-α、IL-10mRNA表达的影响,探索最佳的丙泊酚剂量,为其防治体外循环引起的心肌缺血再灌注损伤提供依据。方法选择拟行体外循环（CPB）的心脏手术成年患者60例,ASAⅡ～Ⅲ级,随机分为低剂量组（A组）2μg/ml,中剂量组（B组）3μg/ml,高剂量组（C组）4μg/ml,每组男、女各10例。利用RT-PCR法比较各组细胞因子TNF-α、IL-10mRNA的表达。结果停止体外循环后各时间点血清促炎性细胞因子TNF-αmRNA表达增强 ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Defect engineering has been widely demonstrated as an effective strategy for enhancing the activity of OER metal catalysts, among which the introduction of twin boundaries (TBs) has proven particularly efficient. However, single‐type defects offer limited performance enhancement.

Gongye shui chuli, 2021 以土霉素制药废水为研究对象进行电子束辐照试验，研究了辐照剂量、初始COD、pH及无机离子浓度对COD去除效果的影响。结果表明：电子束辐照技术可有效降低废水中的COD，COD去除率随辐照剂量的增加而不断升高，相同辐照剂量下COD去除率随废水初始浓度的升高而降低，辐照降解规律符合准一级动力学方程。废水最佳pH=5，且不同初始pH的废水经辐照后，水样pH均随辐照剂量的增加而不断降低，主要由产生的小分子有机酸所致。较高的无机离子浓度会导致COD去除率降低。
