Crystallographic symmetry effect on the nucleation in non-equilibrium aggregation pattern

Spontaneous Formation of Sinuous and Wavy Micropatterns with Helical Growth of CuSO4·5H2O in Polymer Matrix

“…Crystal growth is regarded as an important phenomenon for the bottom-up approach to fabricate particular periodic patterns. For instance, several kinds of dendritic structures were formed through branching growth of inorganic crystals in a diffusion field. − Thus, the controlled crystal growth has potential as a useful pattern formation technique. Here, novel sinuous and wavy patterns are shown to be spontaneously produced by specific crystal growth in the polymer matrix.…”

Effect of Ammonium Chloride Solution on the Growth of Phosphorus Gypsum Whisker and Its Modification

“…Therefore, it can be concluded that the main structure of dendritic crystal was CaSO 4 ⋅2H 2 O, and the branches were NH 4 Cl. According to the research [26][27][28], the mechanism of the formation and the growth of seaweed-like dendrite of NH 4 Cl was a crystal surface of a "mother" crystal nucleation and growth of second "sub" crystal. In this paper, the main component of the crystal was CaSO 4 ⋅2H 2 O, so it must be the "mother" crystal.…”
