  1. Morphology analysis of magnesium hydroxide prepared by magnesium oxide hydration within seawater

    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.

  2. Selective etching of ZnTe in HF:H2O2:H2O solution: Interpretation of extended defect-related etch figures

    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.

  3. Formation of longitudinal aggregation of inclusions in bulk sapphire and yttrium-aluminum garnet grown by horizontal directed crystallization method

    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.

  4. Electrospinning synthesis and photocatalytic property of CaFe2O4/MgFe2O4 heterostructure for degradation of tetracycline

    CaFe2O4/MgFe2O4 nanowires have been successfully designed and prepared by electrospinning method. The obtained nanowires showed enhanced photocatalytic activity for degrading of tetracycline (TC) under visible light, which could be attributed to the heterostructure of CaFe2O4/MgFe2O4 nanowires that repressed the recombination of photo-generated electrons and holes.

  5. Bridgman growth and characterization of birefringent crystal NaNO3

    High quality NaNO3 single crystals with size of Φ20×100mm3 were grown by Bridgman method. The principal refractive indices of NaNO3 crystal were measured and the corresponding Sellmeier's equation was obtained by auto-collimation method. NaNO3 crystal demonstrates its better birefringent property. The transmittance and photoluminescence properties were also discussed in this paper.
