  4. 2. Dynamics of Disordered Materials in Confined Geometries

    Author : Christer Svanberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer film; glass transition; confinement; polymer gel; dynamics; dielectric spectroscopy; gel electrolytes; relaxation; photon correlation; cooperativity;

    Abstract : This thesis is concerned with effects of geometrical confinement on dynamics in disordered materials in the nanoscopic range. Of particular interest is the dynamics around the liquid to glass transition. Two systems have been investigated: thin polymer films and polymer gels. READ MORE

  5. 3. Ultrafast Photo-induced Reaction Dynamics of Small Molecules

    Author : Malin Kadi; Jan Davidsson; Eva Åkesson; Sören Keiding; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pump-probe spectroscopy; reaction dynamics; photodissociation; aryl halides; spin-orbit coupling; ab initio calculations; molecular dynamics; vibrational wavepackets; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Abstract : The main focus of this thesis is the investigation of the dissociation dynamics of aryl halides using femtosecond pump-probe spectroscopy. In the monohalogenated aryl halides, iodo-, bromo- and chlorobenzene, the rate of dissociation following excitation at 266 nm in the gas phase increased with increasing mass of the halogen atom.

  6. 4. Water and Protein Dynamics in Biological Systems Studied by Magnetic Relaxation Dispersion

    Author : Erik Persson Sunde; Biofysikalisk kemi; []
    Keywords : protein dynamics; ubiquitin; BPTI; Escherichia coli; Haloarcula marismortui; nuclear magnetic resonance; protein hydration; magnetic relaxation dispersion; water dynamics; cell water;

    Abstract : The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecules between internal cavities and the surrounding bulk solvent phase.

  7. 5. Local Structure and Dynamics of Next Generation Electrolytes - linking microscopic and macroscopic properties

    Author : Filippa Lundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QENS; Ionic Liquids; Highly concentrated electrolytes; Dynamics; SAXS; Ion Transport; Electrolytes; Structure;

    Abstract : The electrolyte is a crucial part of a battery in terms of performance, longevity and safety. However, the state-of-the-art electrolytes for lithium-ion batteries are based on organic solvents and Li-salts (typically at 1M concentration) which are volatile and degrade at higher temperatures.
