Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little (but not literally zero) force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is moved, pushing all the sprung contacts apart so that the IC can be inserted with very little force ...

2024年9月15日 · Herein, a pH/enzyme dual-responsive active packaging was fabricated based on in situ growth of ZIF-8 nanoparticles (ZIF-8 NPs) on TEMPO-oxidized cellulose (TOCNF) film and loading with carvacrol (CAR), after that electrostatic adsorbing pectin as “gatekeeper” for fruit preservation. The developed CAR@ZIF-8/TOCNF/Pec film was able to respond ...

Ni/Co-ZIF-67衍射峰强度大于ZIF-67, 说明合成的Ni/ Co-ZIF-67结晶度更高, 这与镍元素的添加有关. 聚多 巴胺(polydopamine, PDA)是一种优异的包覆材料, 在 碱性环境下可以生长在大多数材料表面[14], 但碱性缓 冲液会破坏Ni/Co-ZIF-67的结构. 因此, 在包覆过程中,

2024年7月12日 · 自己在群里、数据库找了好几份ZIF-67的CIF，打开发现-CH3的碳上连着6个氢，不知道是不是因为这个原因，导致同步辐射拟合程序报错。 看到论坛一个帖子讲ZIF-8的CIF也是这样，可能是没经过精修的原因（原帖：求助：从CCDC晶体数据库下载MOF模型，导入MS软件构建问题http://bbs.keinsci.com/forum.php ... 5&fromuid=65783），特来求助下。 如能探讨同步辐射拟合更好。 感谢！ 求ZIF-67精修的CIF文件。 自己在群里、数据库找了好几份ZIF-67 …

制备钴基碳材料的前驱体有很多，其中2-甲基咪唑钴盐（ZIF-67）具有丰富的钴和氮源、比表面积大等优点，被广泛应用于制备ORR和OER催化剂。 然而，ZIF-67通常需要高温热解才能获得所需的催化剂，在这种情况下钴原子会自发聚集形成大尺寸的钴颗粒，导致电化学活性面积和活性位点减少。 在此，为了减少ZIF-67自身碳化引起的各种不利影响因素，我们选择了三种不同的具有配位功能的有机化合物（抗坏血酸 、 柠檬酸 和 EDTA二钠）来锚定和分散ZIF-67中Co离子，形貌 …
