微米线性链（1D阵列），单层（2D阵列），和超结构（3D阵列）的各向异性Mn3O4 nanocuboids选择性地产生定向自组装通过蒸发的分散体。ID阵列基本上是通过矩形晶体在该方向上的定向自组装在衬底上形成< 100 >的。通过调节分散体的颗粒浓度获得2D和3D微阵列。通过改变介质的极性，控制了[001]晶向与衬底平行和垂直。
Micrometric linear chains (1D arrays), monolayers (2D arrays), and superstructures (3D arrays) of anisotropic Mn3O4 nanocuboids were selectively produced by oriented self-assembly through evaporation of a dispersion. The ID arrays were basically formed on a substrate via oriented self-assembly of the rectangular crystals in the < 100 > direction. The 2D and 3D microarrays were obtained by adjusting the particle concentration of the dispersion. The [001] direction of tetragonal crystal was controlled to be parallel and perpendicular to the substrate by changing the polarity of the medium.
