  • Continuous synthesis of metal-organic frameworks under high pressure

    Creator:
    Li, Yong J.
    Abstract:
    Metal Organic Framework (MOF) materials, consisting of metal ions with organic linkers, have a functional cavity structure which can be utilized in applications such as catalyst, micro sensing, and gas absorption. Due to MOF materials' selective gas adsorption property, interest in MOF materials has intensified in the last few years,...

  • An investigation of the crystal growth of the heavy metal sulfides in supercritical hydrogen sulfide

    Creator:
    Lewis, Leroy Crawford
    Abstract:
    Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin,...

  • Dipole relaxation effects in doped potassium chloride by the double crystal method

    Creator:
    Chaney, Robert Edgar
    Abstract:
    The investigation of impurity effects on the properties of alkali halide crystals has often been difficult because of the variation of procedures used in various experiments. The purpose of this work is to develop a self consistent method of measuring the IV dipole polarization properties of single crystals while eliminating...

  • Effect of capacitor discharge welding on single crystal copper

    Creator:
    Thaneepakorn, Wiwat
    Abstract:
    Materials which can be changed in shape and size when exposed to a magnetic field are called magnetostrictive materials. The magnetostrictive material was developed for use in the many actuator industries. A single crystal of magnetostrictive material is used to maximize its magnetostrictive response. It can be produced by the...

  • Continuous flow synthesis of lead sulfide and copper indium diselenide nanocrystals

    Creator:
    Knapp, Michael W.
    Abstract:
    The use of size and shape tunable quantum confinement nanocrystals has many potential applications for use in semiconductors, optics and sensors. The synthesis of lead sulfide (PbS) and copper indium diselenide (CuInSe₂) nanoparticles are of particular interest for use in semiconductor, optoelectronics and bio-medical applications. The continuous synthesis of lead...

  • Optical and EPR investigations of the photochemistry of KCl:OH

    Creator:
    Bowen, Robert Clifford
    Abstract:
    The hydroxide ion as a substitutional defect in KC1 can be photo-dissociated at liquid nitrogen temperature by ultraviolet light. The photochemistry of this system was investigated by EPR and optical absorption methods. Theoretical calculations were also performed in an investigation of the KC1:OH system. The bleaching behavior of photochemically colored...

  • Synthesis and structure of new transition metal containing bismuth oxides

    Creator:
    Xun, Xiumei
    Abstract:
    Exploratory synthesis is the discovery of new compounds with interesting structures and properties. The subject of this thesis is exploratory synthesis of bismuth containing oxides. Bismuth containing oxides have many interesting properties, which are ionic conductivity, ferromagnetism, superconductivity, ferroelectricity, ferroelasticity and catalytic. These properties are closely related to their specific...
