  1. 1. Surface Vibrational and Electron Spectroscopy - Experiments and first-principle calculations

    Author : Martin Andersson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gränsskikt; anharmonicity; Ytkemi; Surface and boundary layery chemistry; adsorbates; metal surface; density functional theory; first-principle calculations; electron spectroscopy; reflection-absorption infrared spectroscopy; vibrational spectroscpy;

    Abstract : This work deals with interpretation of experimental surface spectroscopic data with the aid of first-principle calculations. Surface infrared reflection-absorption spectra as well as spectra from the electron spectroscopic methods photoemission and X-ray absorption are considered. READ MORE

  2. 2. Ellipsometry studies of liquid interfaces: New methodology and applications

    Author : Jan-Willem Benjamins; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface and boundary layery chemistry; Ytkemi; gränsskikt; phospholipids; lactoglobulin; air water; oil water; block copolymers; nonionic surfactants; Brewster angle microscopy; Ellipsometry; adsorption;

    Abstract : Adsorption of several surface active agents, such as nonionics, diblock copolymers, triblock copolymers, proteins and phospholipids at the oil/water and air/water has been studied. In order to be able to do this, a new ellipsometry setup, which utilizes light guides, was developed and tested. READ MORE

  3. 3. Infrared and Photoelectron Spectroscopic Studies of Adsorbates on Solid Surfaces: Experiments and DFT Calculations

    Author : Jakob Blomquist; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magnetic resonance; supraconductors; magnetic and optical properties; electrical; Solid Surfaces; Chemistry; Kemi; Condensed matter:electronic structure; FTIR spectroscopy; DFT Cluster calculations; Anharmonicity; Photoelectron spectroscopy; relaxation; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; egenskaper elektriska; magnetiska och optiska ; supraledare; magnetisk resonans; spektroskopi; Surface and boundary layery chemistry; Ytkemi; gränsskikt;

    Abstract : In general, the more complex and real a system is, with all its interactions with solvents and contaminations etc., the harder it is to accurately model it and reproduce the experimental results by calculations. READ MORE

  4. 4. DNA Compaction at Surfaces

    Author : Marité Cárdenas; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; Fysikalisk kemi; Physical chemistry; gränsskikt; Ytkemi; Surface and boundary layery chemistry; cationic amphiphiles; DNA; Polymerteknik; surface; biopolymers;

    Abstract : The interfacial behavior of DNA and DNA-cationic surfactant has been studied. Particular attention was paid to the type of cationic surfactant and the DNA conformation (single or double stranded) as well as the DNA length. READ MORE

  5. 5. Interfacial behaviour of surfactants and enzymes: studies at model surfaces
