    The surface morphology, of the diamond films can be generalized as step/ledge structures: clear upper ledges followed by lower ledges. Increase in step/ledge population was clearly associated with increase in 13C concentration. 13C concentration and increased step/ledge population also supported developments in ‘other’ crystallographic orientations. The principal (100) component was split between two near (100) components, often constituting the individual steps/ledges. High resolution EBSD also established the presence of non-(100) orientations. These were present at the ledge/step boundaries and corners. At lower 13C concentration, their presence was virtually eliminated.

    Two new isostructural rare-earth orthoborates KBaPr(BO3)2 and KBaNd(BO3)2 were synthesized. Both of them are stable in the temperature range 850–1000°C. Prepared compounds crystallize in the trigonal system with space group Rinline imagem with cell parameters of а =  5.5052(12) Å, с =  18.402(8) Å, Z = 3 for KBaPr(BO3)2 and cell parameters of а =  5.4956(5) Å, с =  18.278(3) Å, Z = 3 for KBaNd(BO3)2. The photoluminescence, IR spectra of KBaPr(BO3)2 and KBaNd(BO3)2 have been studied.

  3. Fabrication of BiOI hierarchical microspheres with efficient photocatalysis for methylene blue and phenol removal

    BiOI hierarchical microspheres were synthesized by a solvothermal method. The formation of BiOI hierarchical microspheres were discussed with different ratio of the amount of substance in mixed alcohol. Ethylene glycol acts as the soft template, and the presence of methanol has a positive effect on uniformity of reaction system. The result shows that BiOI samples is a promising photocatalyst in practical application.

    We developed the growth technique of the CeBr3 scintillator single crystal by a Halide-micro-pulling-down (H-μ-PD) method. Four-types after-heaters with different configurations were prepared to control the temperature gradient around the liquid-solid interface during crystal growth. CeBr3 single crystal with high transparency could be obtained by the high temperature gradient. The light yield and the decay time under γ-ray irradiation were ∼68,000 ph/MeV and 19 ns, respectively.

    Large-grained short columnar α-calcium sulfate hemihydrate with the length of 50 μm and length-diameter ratio of 1 can be prepared with a low salt content (3%) using FGD gypsum after three times washing. Analysis of low salt content and washing step was conducted in this paper. It shows that these two factors can make sure to get large-grained crystals with smooth surface and high integrity and achieve the circulation of mother liquid further.
