Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Diabetic chronic wounds, characterized by a unique pathological microenvironment including persistent hyperglycemia, excessive reactive oxygen species (ROS), bacterial infection, and sustained inflammation, exhibit notoriously impaired and delayed healing processes. This study developed a multifunctional hydrogel therapeutic system (GOx@Zn‐MPN

Etnografia é, etnografia não é
Ilha Revista de Antropologia, 2017 Usando uma noção de "digital" como uma de suas metáforas principais, uma versão do termo que se apoia na discussão de Kara Keeling sobre o "humanismo digital", este texto argumenta que há algo sobre as não-linearidades que definem a diferença da digitalidade que pode nos ajudar a pensar sobre recalibragens no próprio projeto etnográfico.

Dianci bileiqi, 1975 提高绝缘子金属附件热镀锌层均匀性,对延长绝缘子的使用寿命是有好处的。在批林批孔运动的推动下,我们对提高热镀锌层均匀性的问题进行了研究,已初见成效。实践证明,提高热镀锌层均匀性的关键在于工艺方法的改进。我厂旧的热镀锌工艺的特点是：(1)镀锌温度高,一般在550—600℃; (2)在锌液中加铝,增加锌液的流动性和提高锌层表面的光泽;(3)不使用"助镀溶剂",酸洗烘干后立即镀锌;(4)锌层镀后没有冷却就用"卡"、"墩"的方法除掉表面的积锌。这就使锌层薄而不均匀,致使锌层硫酸铜试验次数很低 ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Lithium metal anode and zinc metal anode have attracted considerable attention owing to their high theoretical capacity, low electrochemical potential, and superior electronic conductivity. However, their practical applications are greatly hindered by inherent issues such as uncontrollable dendritic growth and interfacial instability ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Biodegradable zinc (Zn)‐based materials are considered promising candidates for orthopedic applications because of their favorable mechanical properties, controllable biodegradability, and good biosafety profiles. However, their clinical translation is limited by early‐stage corrosion‐induced cytotoxicity and inflammation, as well as ...
