    Evaporation and solution morphologies of ZnO single crystals (1971)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 4 (1971), S. 379-383 
    Details
    ISSN: 1600-5767

    Topics: Geosciences , Physics
    Notes: The evaporation and solution morphologies of ZnO single crystals have been investigated. In the case of solution etching, using HCl, the {00.1} surface develops etch pits with sharp rims while for the {00.\overline 1} surface, etch-pit rims are unstable. Similar effects are found for evaporation near 1035°C. As the evaporation temperature is increased to near 1200°C, however, the {00.\overline 1} surface becomes increasingly complex before assuming a more stable habit at still higher temperatures. Both {10.\overline 2} and {11.\overline 2} planes are developed on the {00.\overline 1} surface, but the corresponding planes on the {00.1} surface are not observed. (The development of second order pyramidal planes is also observed in vapor grown needles from ore-processing furnaces).

    Laser reflectogram method for the study of crystal surfaces and epitaxial deposits (1967)
    Springer
    Journal of materials science 2 (1967), S. 470-473

    ISSN: 1573-4803

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract When a collimated beam of light is reflected from an etched crystal surface or an epitaxial deposit, the pattern formed by this reflection provides information on the microscopic morphology of the reflecting surface. Using a He/Ne laser as a source of high-intensity collimated light, both SiC etched in CIF3 and cubic CdS grown epitaxially on GaP have been examined. Certain regions of the SiC were found to give rise to diffraction effects in the resulting reflectrogram. The epitaxial layer of CdS was found to show a threefold symmetry indicative of a {111} deposit and a negligible diffraction effect.

    Thermal processing of ilmenite and titania-doped haematite using microwave energy (1989)

    Notes: Abstract To test the potential for microwave processing of lunar materials the heating of ilmenite-rock mixtures, and TiO2-doped haematite were investigated using microwave radiation, llmeniterich rocks will couple, without a coupling agent, to microwave radiation. The microwave experiments are repeatable. Attempts to couple TiO2-doped haematite to microwave radiation were very successful, with susceptibility increasing with TiO2 content. Scanning electron microscopy (SEM) showed increased grain size and particle size with increased TiO2 content in the microwave-heated products of the haematite-TiO2 system. The differences between microwave and furnace melts of ilmenite-rich rocks were also investigated. Petrographic analysis revealed a large amount of titanomagetite in microwave melts while furnace melts contained a large amount of haematite, but the cause of this difference is not fully understood.

    The preparation of textured Te thin films with pronounced acicular morphology and concomitant high absorptivity (1979)
    Springer
    Journal of materials science 14 (1979), S. 2709-2712

    ISSN: 1573-4803

    Notes: Abstract The dependence of surface morphology, and resultant absorptivity, on deposition angle for vacuum deposited Te films has been studied. A deposition angle of 80° was found to yield surface morphologies comprised of acicular crystallites of appropriate dimension and geometry for the trapping of solar incident radiation through multiple reflection. Solar absorptivities across the visible spectrum as high as 95% are manifested by such surfaces.

    Notes: Abstract Calcium carbide and its combination with sodium carbide, lithium carbide and cerium carbide were studied via X-ray diffraction to determine the solid solubilities of these latter carbides in calcium carbide. No solid solubility of sodium or lithium carbide in calcium carbide was found but cerium carbide appears to be soluble up to approximately 40 mol% in CaC2.

    The equilibrium and non-equilibrium thermal behaviour of aqueous ternary solutions based on complex physiological support media, containing NaCl, and dimethyl sulphoxide or glycerol (1977)

    Notes: Abstract The effects of substituting a physiological support medium for water on phase diagram relationships in ternary systems composed of an aqueous component base (water or Eagle's minimum essential medium), NaCl, and a cryoprotective agent (glycerol or dimethyl sulphoxide) have been studied by differential thermal analysis. Primary solidification and eutectic transformations were observed, and both the transition temperatures and devitrification behaviour of non-equilibrium glassy phases were recorded. For most solutions it was found that substitution of the complex support medium for water had very little effect on equilibrium phase relationships. However, the aqueous component substitution resulted in small but measurable changes in the thermal behaviour of non-equilibrium glassy phases. In general, glass stability is enhanced. It is believed that the formation of stable glass phases plays a significant role in cryoprotection.

    The primary ice phase field in the H2O-NaCl-dimethyl sulphoxide ternary system (1978)

    Notes: Abstract The determination and application of H2O-NaCl-cryoprotective agent phase diagram information appears to be a fruitful area for co-operative research between materials scientists and biologists. Dimethyl sulphoxide (DMSO) is a widely used cryoprotective agent, and in this present work the primary ice phase field in the H2O-NaCl-DMSO system has been determined including the extension into this system of the lines of two-fold saturation from the ice-NaCl · 2H2O and the ice-DMSO · 3H2O binary eutectics. Liquidus surface data are presented for isoplethal sections taken through the ternary system along composition lines defined by weight ratios of DMSO to NaCl of 1/5, 1/2 and 9. Liquidus surface data obtained from an additional thirteen isoplethal sections are used to construct the complete isothermal projections of the primary ice phase field along 10° C contours. The distribution and occurrence of glassy phases in this ternary system are also discussed.
