Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

一株抗H5亚型禽流感病毒血凝素蛋白单克隆抗体的广谱中和活性 [PDF]
, 2007 以H5N1禽流感病毒株Ck/HK/Yu22/02作为抗原,应用常规杂交瘤技术和血凝抑制实验筛选出抗H5亚型禽流感病毒血凝素蛋白的单抗8H5,单抗8H5经免疫荧光鉴定具有很好的H5特异性。选择33株2002~2006年不同地域,不同宿主中分离的不同遗传变异亚系的H5N1病毒代表株,对单抗8H5分别进行血凝抑制实验及中和试验分析,结果显示单抗8H5对所有H5亚型病毒均有较强反应,而对非H5亚型标准病毒株均不反应,说明8H5是一株广谱性抗H5特异性中和单抗 ...

Antipode, Volume 58, Issue 1, January 2026.Abstract This paper investigates the infrastructures that support migrant workers in pursuing fairer and more just employment experiences, despite structures that reproduce exploitative working conditions and keep them at the margins of society. Intervening at the intersection of infrastructural and labour geographies, I bring together the conceptual ...
