  1. Bond selection during protein crystallization: Crystal shapes

    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.

    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.

    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.

  4. Selective etching of ZnTe in HF:H2O2:H2O solution: Interpretation of extended defect-related etch figures (pages 215–222)

    40%wt.HF:30wt.%H2O2:H2O (3:2:1 by volume) solution shows strong orientation and phase selectivity, it is also very sensitive to impurity decorated defects, thus can effectively reveal various extended defects (line, face and volume defects) of ZnTe crystals. In addition, smaller size texture pits are also produced on the defect-free regions, which serve as reference standard pits during the analysis of defect-related etch figures.

  5. Formation of longitudinal aggregation of inclusions in bulk sapphire and yttrium-aluminum garnet grown by horizontal directed crystallization method (pages 223–229)

    At the growth of sapphire and yttrium-aluminum garnet by the method of horizontal directed crystallization, longitudinal aggregation of inclusions located along the growth direction may be formed in the crystals. Such an effect is shown to be caused by the formation of two-vortex convection of the melt that leads to local increase of the thickness of the diffusion layer and capture of inclusions by crystallization front. Considered is the influence of the thermal conditions of the growth and the geometrical parameters of the melt zone on the formation of longitudinal aggregation of inclusions.
