Using liquid-cell transmission electron microscopy, the transformation of irregular palladium nanoclusters to fractal nanocrystals is in situ investigated. The results demonstrate that increasing the difference between the atomic formation/incorporation rates and diffusion rates can promote the formation and growth of dendrites via supersaturation mediated kinetics control.
利用液池透射电子显微镜，对不规则钯纳米团簇向分形纳米晶体的转变进行了原位研究。结果表明，增加原子形成/掺入速率与扩散速率之间的差异，可以通过过饱和介导的动力学控制促进枝晶的形成和生长。
