那么Et3NH+ 与Me3NH+相比 前者体积更大 所以同种阴离子的话其构成的离子液体熔点低而AlCl4-与BCl4-相比.似乎是AlCl4-的体积要大一些.【觉得Al3+ 比B3+大.】两个较大的离子构成的离子液体应该熔点低 所以觉得是A.【话说因为对自己的结论不确定所以特地很无耻地匿了 仅作提供思路 抱头逃走.= =】...

BN coatings from BCl 3 -NH 3 -H 2 gas mixturesstability in airambient temperatureSummary Generally, BN coatings processed from BCl 3 -NH 3 -H 2 gas mixtures display a poor degree of crystallisation under commonly used CVD/CVI conditions (low pressure and temperature). The crystallisation of ...
We have tried to grow CH_3NH_3PW_3 (MAPW3) on CH_3NH_3PbBr_3 single crystal substrate, but only obtained CH_3NH_3Pb(Br_(1-x)I_x)_3 alloy due to interdiffusion of halogen ions . In order to get heterostructure of pure perovskites, we replaced the substrate with CH_3NH_3PbCl...
