Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT A synergistic strategy combining a Ti interlayer and circular beam oscillation was proposed to improve the laser weldability of 6082‐T6 aluminum alloy. The Ti interlayer suppressed porosity, eliminated columnar grains, and significantly reduced grain size by 67.7% at the weld center. Mechanistically, fine L12‐Al3Ti precipitates clearly showing

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Non‐noble metal oxygen electrocatalysts are essential for low‐cost rechargeable metal‐air batteries and fuel cells, determining their energy conversion efficiency. However, such electrocatalysts are limited by inadequate bifunctional activity and stability toward the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Regulating oxygen vacancies (Ov) in SnO2 to facilitate high‐efficiency carbon dioxide electroreduction reduction reaction (CO2RR) is still a significant challenge. Therefore, a strategy based on Ag‐induced interfacial electron transfer was proposed to modulate Ov in SnO2 for CO2 electroreduction. The prepared Ag/SnO2 with an optimal Ov content

四川大学学报. 自然科学版, 2010 从小叶女贞叶片中提取分离了具有抑制脲酶作用的活性成分并对其抑制作用进行研究.结果显示该活性物质主要成分为多糖和酚类物质,对脲酶有较强的抑制作用,随着脲酶抑制物质浓度增加,抑制作用增强.加入β-巯基乙醇(2-Me)后,脲酶的活性恢复,说明该脲酶抑制物质是通过与脲酶的-SH发生作用而导致脲酶的活性降低.

Gongye shui chuli通过序批式试验比较了不同投加量的生物硝化抑制剂〔对羟基苯丙酸甲酯（MHPP）、丁香酸（SA）〕与化学硝化抑制剂〔二氰二胺（DCD）、3，4-二甲基-1H-吡唑（DMPP）〕对硝化菌群的影响。结果表明，这4种硝化抑制剂在最适浓度下，显著抑制了亚硝酸盐氧化菌（NOB）的处理效能，从而降低了亚硝态氮转化率，抑制率达71.31%~87.38%。DCD、DMPP对氨氮转化率产生了一定的抑制作用，而MHPP、SA并未显著影响氨氧化菌（AOB）对NH4+-N的转化。亚硝化过程的主要功能菌AOB ...

Zhongshan Daxue xuebao. Yixue kexue ban, 1984 鼻咽癌病人细胞免疫功能有不同程度的降低,已见于国内外的报道。唯其功能降低的机制,尚待进一步探讨。自Gershon等(1977)发现抑制性细胞后,对其抑制性细胞的认识取得了很大进展,不少报道证实抑制性细胞在肿瘤免疫中起重要作用,本文就ConA诱导鼻咽癌病人抑制性细胞进行初步研究,了解病人的抑制性细胞的活性与免疫功能的相互关系,以探讨病人的细胞免疫功能低下的抑制。
