  2. 1. Physical Properties and Structural stability of carbon nanotubes under extreme conditions

    Author : Maxime Noël; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Experimental physics; Experimentell fysik; Fysik; Fysik;

    Abstract : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. READ MORE

  5. 3. Examination of Dissociative Recombination Processes of Importance for Astrochemically Evolving Interstellar Clouds

    Author : Matthias Hamberg; Wolf Geppert; Peder Royen; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dissociative Recombination Astro Chemistry; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Abstract : Each single moment a myriad of processes is taking place throughout the universe. A great deal of them has been found to be dissociative recombination (DR) reactions. In this thesis the major work described are related to experimental determination of reaction rates and how the reaction products splits up into their final fragments. READ MORE

  6. 4. On Phase Behaviours in Lipid/Polymer/Solvent/Water Systems and their Application for Formation of Lipid/Polymer Composite Particles

    Author : Anna Imberg; Per Hansson; Krister Thuresson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Biodegradable; CLSM; Composite Particles; Controlled Release; Cubic Phases; Drug Delivery; Flory-Huggins Theory; FT-PGSE-NMR; IPMS; Liquid Phase; Lipid Domains; Liquid Handler; Microspheres; Microstructure; Phase Behaviour; Phase Separation; Polymer Matrix; SAXS; Segregation; Sponge Phase; Swelling; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

    Abstract : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. READ MORE

  7. 5. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties

    Author : Zdenek Tosner; Jozef Kowalewski; Josef Stepanek; Klaus Muller; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; supramolecular chemistry; host-guest complexes; non-covalent interactions; nuclear magnetic resonance; molecular motion; C-13 relaxation; deuterium NMR; dipolar recoupling; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis discusses several different methods offered by solution and solid state nuclear magnetic resonance for investigation of host-guest complexes and their constituents. The presented methods were used especially (but not exclusively) to address rotational dynamics of the bound guest in different molecular systems. READ MORE
