  1. 1. Theoretical studies of collective electronic excitations in low-dimensional structures

    Författare :Zhe Yuan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; linear atomic chains; hydrogen storage; nanodisks; dielectric response; surface plasmon resonances; electron gas model; electronic excitation; metallic thin films; time-dependent density functional theory;

    Sammanfattning : During the past decade, nanoplasmonics and nanophotonicshas emerged as a new branch of nanosciences with many novelapplications. Central in this development is the localized surface plasmon resonance (LSPR) tunable by the sizes and shapes at nanometer scale. LÄS MER

  3. 2. Infinite-state Stochastic and Parameterized Systems

    Författare :Noomene Ben Henda; Parosh Abdulla; Christel Baier; Uppsala universitet; []
    Nyckelord :program verification; model checking; stochastic games; infinite-state systems; Markov chains; reachability; repeated reachability; parameterized systems; approximation; safety; tree systems;

    Sammanfattning : A major current challenge consists in extending formal methods in order to handle infinite-state systems. Infiniteness stems from the fact that the system operates on unbounded data structure such as stacks, queues, clocks, integers; as well as parameterization. LÄS MER

  4. 3. Structural studies of heterogeneous amyloid species of lysozymes and de novo protein albebetin and their cytotoxicity

    Författare :Vladimir Zamotin; Ludmilla Morozova-Roche; Daniel Otzen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amyloid; cytotoxicity; atomic force microscopy; Biophysics; Biofysik;

    Sammanfattning : A number of diseases are linked to protein folding problems which lead to the deposition of insoluble protein plaques in the brain or other organs. These diseases include prion diseases such as Creutzfeld-Jakob disease, Alzheimer's disease, Parkinson's disease and type II (non-insulin dependent) diabetes. LÄS MER

  5. 4. Crystallization in Constrained Polymer Structures : Approaching the Unsolved Problems in Polymer Crystallization

    Författare :Eugenia Núñez; Ulf W. Gedde; Bernard Lotz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crystallization; Constrained structures; poly ε–caprolactone ; poly ethylene oxybenzoate .; Polymer chemistry; Polymerkemi;

    Sammanfattning : The knowledge regarding certain issues in polymer crystallization e.g. the possible existence of short–lived mesophases remains inconclusive due to experimental limitations. Polymers undergo chain folding upon crystallization, which introduces some complications that are not found in crystallization of low molar mass materials. LÄS MER

  7. 5. Crystalline cellulose in bulk and at interfaces as studied by atomistic computer simulations

    Författare :Malin Bergenstråhle; Lars Berglund; Stephen Eichhorn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose; molecular dynamics simulation; interfaces; Chemistry; Kemi;

    Sammanfattning : Cellulose is a linear polysaccharide, serving as reinforcement in plant cell walls.Understanding its structure and properties is of importance in the developmentof nanostructured cellulose materials. LÄS MER
