In water, metallic indiumpromotes carbon-sulfur bond coupling reaction of aromatic sulfonyl chloride withsuitable organic halides to afford sulfones. In the last chapter, metallic tin mediated allylation of aldimines with allylbromide was revealed.

第三章，我们研究了在水相介质中金属铟促进的烯丙基溴对1，1-二氰基-2-芳基乙烯的Michael加成反应，生成一个含碳碳双键和二个碳氮叁键的三官能团化合物，另外，金属铟在水介质中还可以促进芳基磺酰氯与卤代烃发生碳硫键的偶联，生成砜。

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。
