- Preparation of dendritic-like CdS by hydrothermal method and its photocatalytic performance
Xiande Yang, Yongqian Wang, Tingting Jiang, Jun Yang, Yinchang Li and Qun Ma
Article first published online: 1 APR 2015 | DOI: 10.1002/crat.201400476
The CdS crystals we prepared are dendritic-like structures. The length of each dendrite is about 6 μm. Cd(NO3)2·4H2O:thiourea = 0.01 mol: 0.03 mol is conducice to form dendritic-like structures. The reaction time and temperature are the main influence on the morphology of CdS. The growth mechanism for the formation of dendritic-like CdS is reasonable. The photo-degradation rate of methylene blue with our CdS can reach 92.1%.

Amorphous calcium carbonate (ACC) is chosen as a precursor for crystallization in this experiment: more water can direct transformation of ACC into calcite fast when R = 1/3; aragonite phase is achieved with the ethanol content increasing at R = 3/1; with a further altering, poly (allylamine hydrochloride) (PAH) is added at R = 3/1, vaterite is obtained as the main crystal.

Traits of protein crystallization are explained by the bond selection mechanism, BSM. Assuming intra-crystalline repulsion, arising due to protein surface patch-to-patch incompatibility, the molecular scale mechanism of formation and growth of 1D and 2D protein crystals (including amyloid fibrils and insoluble plaques) are considered from BSM perspective. The interest in such structures rises because they are involved in many neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, etc.
- Crystal structure of aluminum sulfate hexadecahydrate and its morphology

Single crystals of aluminum sulphate hexadecahydrate (Al2(SO4)3•16H2O) were obtained from aqueous solution, and their hexagonal-plate morphologies were captured with a polarizing microscope. The predicted morphology derived from the modified AE model considering solvent effect was consistent with experimental results.
- Morphology analysis of magnesium hydroxide prepared by magnesium oxide hydration within seawater (pages 203–209)

The MgO hydration product was obtained by reacting with seawater under three-phase reaction condition. The particle was hexagon, displaying flower-like morphology and intergrowth of platelets. It is with the ionic effect that the product appears as the figure shown. Furthermore, there existed some fine crystals which adhered to the lager particle. We deduced that the fine crystals were MH which peeled off from the MgO.
