  1. 16. Three-dimensional electron diffraction for studying order, disorder and flexibility in metal-organic frameworks

    Författare :Laura Samperisi; Xiaodong Zou; Sebastian Henke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; continuous rotation electron diffraction; metal-organic frameworks; flexibility; rotational dynamics; atomic displacement parameters; anisotropic refinement; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Metal-organic frameworks (MOFs) represent a class of 3D crystalline porous materials composed of organic linkers and metal nodes. Over the years, tens of thousands of MOF architectures have been developed, addressing various applications such as gas storage and separation, catalysis, chemical sensing, ion exchange and drug delivery.

    Sammanfattning : Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy to perform a variety of different biological functions. LÄS MER

  5. 19. DNA Binding of Metal Complexes. A Spectroscopic Study of Trigonal Ru(II)phenanthroline Complexes and Uranyl(VI) Ion with Respect to Specific Interactions with DNA

    Författare :Catharina Hiort; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uranyl; nucleic acids; optical probes;

    Sammanfattning : The interaction of metal complexes with nucleic acids has attracted attention owing to their potentials as optical probes, probes of chirality, and for use as artificial restriction enzymes. To understand the underlying mechanisms in these contexts we studied the binding to DNA of the enantiomers of two chiral ruthenium(II) metal complexes ([Ru(phen)3]2+ and [Ru(phen)2]2+DPPZ) phen=1,10-phenanthroline, DPPZ=dipyrido[3,2-a:2',3'-c]phenazine, and of the linear uranium(VI) complex, uranyl ([UO2]2+), using linear dichroism, circular dichroism and luminescence, as well as nuclear magnetic resonance spectroscopy.

  7. 20. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems

    Författare :Helena Wassenius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion behaviour; dynamic NMR microscopy; NMR diffusometry; core-shell latex particles; NMR velocimetry; rheology; colloidal systems;

    Sammanfattning : In this thesis, the NMR diffusometry and dynamic NMR microscopy methods were shown to be useful techniques with a great potential for the study of colloidal systems. In Paper I-II, NMR diffusometry was used to study the behaviour of surfactant and polymer molecules that are normally important components in colloidal dispersions and emulsions. LÄS MER
