Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

Gongye shui chuli, 2015 通过分子前驱体Zn[Biedta]2·8H2O热分解得到Zn-Bi-O三元复合氧化物,采用XRD、漫反射光谱、FT-IR等方法探索灼烧时间对复合氧化物的结构和性质的影响。同时以甲基橙的光降解为模型研究了灼烧时间对复合物催化性能的影响。结果表明,灼烧时间对复合物物相、吸光度、催化效果等均存在影响。制备的复合物对甲基橙光降解均具有不同程度的催化能力,其中灼烧2 h所得复合物的催化效果最好,在中性环境中,对20 mg/L的甲基橙而言添加量2 g/L为最佳,光照3 h的褪色率达90%。

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 ...

Novos Estudos - CEBRAP, 2021 O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on

Zhongshan Daxue xuebao. Yixue kexue ban, 2019 【目的】探究锌离子在动脉粥样硬化巨噬细胞泡沫化及斑块形成过程中的影响及其机制。【方法】用氧化低密度脂蛋白（oxLDL）刺激THP-1细胞建立巨噬细胞泡沫化模型，用油红O染色法检测在0、30和60μmol/L锌浓度环境下泡沫化程度，用荧光标记法检测巨噬细胞对脂质的吞噬情况，用免疫印迹法检测相关清道夫蛋白CD36、SR-A蛋白的表达，用实时荧光定量PCR检测锌离子转运体的mRNA相对表达量。用ApoE-/-小鼠随机分4组：正常饲料组（Chowgroup）、高脂缺锌组（HFD-ZnD）、高脂正常锌组（HFD）、

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.
