historyofmolecularmodelsPaperpresentedattheEuroscienceOpenForum(ESOF),2 StockholmonAugust25,2004 十五世纪下半叶形成的结构式，仅仅是分子结构的一种符号。当时的知识使有机化学家正确地推论关于分子结构——原子间的连接并用联线画出——借以代表连接关系，即化学键。随着测定键长、键角实验技术的出现...
Therefore, the pore structure of the prepared MXenes can be greatly adjusted by the manipulation of etchant composition. The above-mentioned two works indicate that the Lewis acidic etching method still possesses broad development space and can be further improved from different aspects...
Density functional theory (DFT) calculations further support the stability of a dangling Ti-NH2 (amide) structure with an adjacent nitrogen vacancy (Fig. 4b). The charge population analysis reveals that the N3- in Ti-NH2 (N1) acts as a Lewis base with a local atomic charge of -0.81 e, ...
