  1. 1. Theoretical perspectives on ultrafast and non-linear spectroscopy

    University dissertation from Lund University, Faculty of Science, Department of Physics

    Author : Emil Vinas Boström; Lunds universitet.; Lund University.; [2018-05-07]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear optics; Ultrafast dynamics; Non-equilibrium Green s functions; Density functional theory; Multi-photon absorption; Second harmonic generation; Desorption dynamics; Auger decay; Charge-separation dynamics; Quantum Zeno effect; Fysicumarkivet A:2018:Vinas Boström;

    Abstract : Ljus kan användas till många saker, allt från att sända radiosignaler och skicka information i optiska fibrer, till att lysa upp hem och utvinna energi via solceller. Det ljus vi är mest vana vid som människor är ett intervall av våglängder mellan 400 och 700 nanometer (en nanometer är en miljarddels meter), som svarar mot alla synliga färger mellan rött och violett.

  2. 2. Studies on the barrier properties of exterior wood coatings

    University dissertation from Stockholm : Byggvetenskap

    Author : Jan Ekstedt; KTH.; [2002]
    Keywords : Coatings; surfactants; water absorption value; EN 927; paint; additives; moisture dynamics; absorption; desorption; artificial weathering; artificial exposure; computerized tomography; MRI.;

    Abstract : Coatings for exterior wood have two basic functions. One isto give an aesthetically acceptable surface appearance andcolour. The other is to provide protection against wooddegradation by microbiological or physical attack. READ MORE

  3. 3. Structure-dynamics relationships in perovskite oxyhydrides and alkali silanides

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Carin Eklöf-Österberg; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogen storage material; long range diffusion; oxyhydride; neutron scattering; localized motion; hydride ion conduction; hydrogen dynamics;

    Abstract : This thesis focuses on investigations of the local structure and dynamics of two classes of hydrogen-containing, energy relevant, materials; perovskite type oxyhydrides BaTiO3-xHx and alkali silanides ASiH3 (A = K and Rb). In the area of oxyhydrides, which are of relevance for the development of electrolytes in fuel cells and batteries, the aim is to elucidate the dynamics and electronic character of the hydrogen species in the materials.

  4. 4. Adsorption of nonionic amphiphiles to solid surfaces

    University dissertation from Physical Chemistry 1, Lund University

    Author : Johanna Brinck; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; silica; solubilisation; self assembly; ellipsometry; mixed micelles; surfactant; kinetics; Adsorption; desorption; Fysikalisk kemi;

    Abstract : In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. READ MORE

  5. 5. Dynamics of Enzymes at Interfaces Lipase adsorption and mobility on solid surfaces

    University dissertation from Stockholm : KTH

    Author : Andreas Sonesson; KTH.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biophysics; surface chemistry; diffusion; enzymes; lipases; adsorption; mobility; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : This thesis aimed to give more insight in the dynamics of enzymes at interfaces. The adsorption and mobility of adsorbed proteins can e.g. give a better understanding of structure-function properties of interfacially active enzymes. READ MORE
