Abstract

A two-tiered organizing scheme with multiple-length scales for construction of dandelion-like hollow CuO microspheres has been elucidated: (1) mesoscale formation of rhombic building units from smaller nanoribbons via oriented aggregation and (2) macroscopic organization of these units into the CuO microspheres. This self-assembly concept may also be applicable to other metal oxides by creating geometric constraints for constructional units.

摘要

已阐明一种用于构建类蒲公英空心CuO微球的具有多个长度尺度的双层组装方案：(1) 通过定向聚集由较小的纳米带形成菱形构建单元的中尺度过程，以及(2) 这些单元宏观组织成CuO微球。通过为结构单元创建几何约束，这种自组装概念也可能适用于其他金属氧化物。
