Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability.

Theory And Practice Research on Marine Ecological Rehabilitative Justice---A Case Study of Marine Oil Spill Ecological Damage [PDF]
, 2015 随着经济的持续快速发展以及人类需求的不断膨胀，人类从自然界获取资源、能源的领域已经从陆地延伸到了海洋，由此给海洋生态带来的损害也是不容忽视的。新工业发展使石油成为国家战略安全的重要标志，远洋石油运输和海上石油钻井平台蓬勃兴起，所造成的海洋石油污染更是触目惊心，这不仅给国家和个人造成重大经济损失，而且还会给海洋生态环境和自然资源带来极大的危害。我国关于海洋生态损害追偿和救济的法律性规定只有《海洋环境保护法》第90条第2款。该款虽然规定海洋环境监管部门可以提起针对破坏海洋生态的索赔诉讼 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Gaoya dianqi, 2012 采用硅氧烷修复液修复交联聚乙烯电缆老化试样中的水树,进而分析修复效果及机理。将介质损耗因数为4%～6%,绝缘电阻7 500～10 000 MΩ的短电缆在7.5 kV 450 Hz交流电压下老化至介质损耗因数达到20%左右,绝缘电阻3 500～5 000 MΩ。然后用压力注入式修复装置把修复液注入缆芯对水树缺陷进行修复。以介质损耗因数、绝缘电阻和击穿电压为指标对修复效果进行评判;通过显微镜切片观察修复前后水树微观形态;通过仿真修复前后水树附近电场分布来分析和验证水树的修复机理。实验结果证明 ...

The role of jumping translocation breakpoint gene promoting instability of genome and the biological function of its protein and potential clinical value [PDF]
, 2014 染色体不稳定性是大多数肿瘤细胞特别是实体瘤细胞和体外转化细胞的基本特征。其表现形式包括整条染色体的获得或缺失，杂合缺失，染色体易位重排，基因扩增等。目前认为染色体不稳定是肿瘤形成的始发因素，出现在肿瘤进展的早期阶段。体内外各种损伤刺激导致的基因组DNA链的断裂是染色体不稳定的根本原因。我们的研究发现，跳跃易位断裂点基因（JTB）在胃癌、肝癌中存在广泛的基因扩增和基因易位行为，而基因的扩增和易位是DNA双链断裂后异常修复的最终结果。JTB基因的断裂易位将导致其编码跨膜结构域的基因序列丢失 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Periodontitis is a chronic infectious oral disease triggered by periodontopathogenic bacteria, resulting in the progressive inflammation and destruction of the tissues surrounding teeth. To achieve reprogramming of the infectious microenvironment for periodontitis therapy, a nanoformulation was proposed by loading polydopamine (PDA) with ...

Studying on Sustainable Urban River Improvement--Cases in Korea and Supplement [PDF]
, 2016 由于全球化、工业化和城市化的发展以及以经济增长为主的政策导向造成了城市的无差别开发和城市环境的恶化。河流流入废水、污水，受到污染，生态环境遭到破坏。环境恶化又导致居民移居，河流沿岸逐渐演变为贫民区，影响城市活力，造成诸多社会问题。 为了缓解城市河流生态环境恶化及其带来的一系列问题，我们要引入自然友好型及可持续性的河流治理。河流空间是所有人都平等地可以使用的公共场所，给所有市民提供休息空间、娱乐空间和文化空间、运动空间、自然学习空间等，还能够提升周边地区的经济价值，让地区经济更加活跃，成为城市地标 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Recently, cobalt/nitrogen co‐doped materials have emerged as heterogeneous catalysts to activate peroxymonosulfate (PMS) and have been applied to advanced oxidation processes for environmental remediation. However, their recyclability and reusability remain major barriers to practical application.

S221T/D225Y mutations of Escherichia coli RecA can transfer RecA from cytoplasm to nucleus in HeLa cells [PDF]
, 2016 RecA/Rad51家族蛋白在进化上是非常古老而又保守的蛋白家族。大肠杆菌RecA基因在同源重组、DNA修复、SOS途径、突变和细胞分裂中起重要作用。人Rad51基因是大肠杆菌RecA基因的直向同源基因，两者起源于同一个祖先基因。人Rad51基因主要参与DNA的修复和重组，并且与肿瘤发生关系密切。原核细胞与真核细胞最大的区别在于原核细胞没有以核模为界限的细胞核，而蛋白质的入核转运机制是一个十分复杂的生物学过程，需要核孔复合体（NPC）、核定位信号(NLS)、核转运受体、RanGTP蛋白等共同参与 ...
