  1. 21. Deciphering conformational ensembles and communication pathways in biomolecules

    Författare :Annie M. Westerlund; Lucie Delemotte; Erik Lindahl; Kresten Lindorff-Larsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; Clustering; Machine learning; Network analysis; Calmodulin; KCNQ1; Biological Physics; Biologisk fysik;

    Sammanfattning : Life is constructed by small building blocks called cells. Proteins are the biomolecules within these cells which carry out different functions. Proteins located in the cell membrane, for example, allow for the transport of ions and small molecules, as well as communication, across the cell membrane. LÄS MER

  3. 22. Design of carbide-based nanocomposite coatings

    Författare :Erik Lewin; Ulf Jansson; Jörg Patscheider; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chemistry; thin film; dc magnetron sputtering; carbide; nanocomposite; PVD; solid solution; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Sammanfattning : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. LÄS MER

  4. 23. VUV Emission and Energy Transfer Phenomena in Rare Gas Mixture Discharges

    Författare :Andrei Morozov; Andreas Ulrich; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; VUV spectra; excimers; energy transfer; rare gas discharges; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : VUV emission spectra of Xe-X (X = He, Ne, Ar and Kr) and of Kr-Y (Y = He, Ne and Ar) mixtures with low concentrations of the heavier gases (0.1 - 1 %) and moderate total pressures (50 - 200 hPa) are recorded near each of the two resonance lines of Xe and Kr in DC glow capillary discharges.

  5. 24. Electronic Structure of Transition Metal Complexes in Silicon

    Författare :Per Tidlund; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uniaxial stress; FTIR; Zeeman spectroscopy; deep levels; phonon-assisted Fano resonances; Physics; Fysik; Au; Fysicumarkivet A:1998:Tidlund; PtLi; AuLi; Pt; Transition Metals; Silicon;

    Sammanfattning : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. LÄS MER

  7. 25. From Oxygen to Oxide: First-Principles Study of Some Key Aspects

    Författare :Behrooz Razaznejad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; potential-enrgy surface; one-dimensional electron gas; adsorption; density functional theory; oxidation; Peierls instability; molecule-surface interaction; plane waves;

    Sammanfattning : Having important technological applications and interesting fundamental science aspects, oxidation of aluminum has received impressive attention. Technologically, the main reason for the great interest is the fact that the oxide film which forms on aluminum protects the surface against further oxidation and corrosion. LÄS MER
