  4. 2. Magnetic ordering and crystal structure in selected transition- metal compounds

    Author : Hui-Ping Liu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; transition-metal compounds; magnetic ordering; crystal structure; magneticstructure; neutron diffraction; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Applications of magnetic materials are inherently related to their crystal, magnetic and electronic structures. In this thesis, experimental and theoretical methods have been focused on magnetic bulk materials from novel chemical synthesis, to X-ray diffraction for initial phase characterisation, and crystal and magnetic structure studies to explain their complex magnetic properties.

  5. 3. The Crystal Structure of III-V Semiconductor Nanowires: Growth and Characterization

    Author : Jessica Bolinsson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal-organic vapour phase epitaxy; MOVPE; scanning tunneling microscopy; cathodoluminescence; XSTM; crystal structure; polytypism; III-V semiconductor materials; nanowires; Fysicumarkivet A:2010:Bolinsson;

    Abstract : This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. READ MORE

  6. 4. Design of new materials with crystal structure-related properties : The role of lone pair cations

    Author : Eleni Mitoudi Vagourdi; Mats Johnsson; Vadim Kessler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystal structure determination; New oxohalide compounds; Lone-pair electrons; X-ray diffraction; Physical properties; Inorganic Chemistry; oorganisk kemi;

    Abstract : Non-centrosymmetry and low-dimensional arrangements, e.g. chains or layers, are very attractive structural characteristics of crystalline compounds since they are linked to some physical properties including nonlinear optical activity, ferroelectricity and magnetic frustration.

  7. 5. Quantum Chemical Interpretation of Protein Crystal Structure

    Author : Kristina Nilsson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structure; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi; protein; ComQum-X; Hess2FF; QM MM; hetero-compound; metal; oxidation state; protonation; force field; quantum refinement; refinement;

    Abstract : An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. READ MORE
