Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

Huli yanjiu, 1993 肾病综合症（简称NS）是儿科泌尿系统中较常见的疾病,其发病占第二位.近40年来,糖皮质激素一直是治疗小儿肾病综合症首选药物,多数患儿需长期服药治疗,临床上复发者较多.经过对20例小儿肾病综合症长期治疗的家庭护理调查,认为复发的原因除单纯激素治疗因素外,还与患儿家庭治疗、生活管理及家长对该病知识的了解程度有密切关系.提示了加强患儿院外治疗护理是维持住院疗效,促进患儿早日康复,防止复发的重要措施。 1 调查资料 我们对1990年以来经住院治疗临床症状缓解而出院后继续院外巩固治疗的20名患儿进行了随访调查.
