... for 160 min. alignment of nanorods could be observed in the self- assembled structures of nanorods in the absence of external field. HR-TEM study indicated that the nanorod was crystalline. The ... capping agents did work well in this IL in helping create the large difference in reactivity among the low-index surfaces of nanocrystals and in facilitating the formation...
