  4. 4. Molecular Processes in Dynamic Wetting : Du som saknar dator/datorvana kan kontakta Cathrine Bergh, [email protected] för information

    Författare :Petter Johansson; Berk Hess; Erik Lindahl; Guillaume Galliero; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; contact lines; nanodroplets; computational physics; molecular dynamics; fluid dynamics; multi-phase flows; electrowetting; Biologisk fysik; Biological Physics;

    Sammanfattning : The spreading of liquids onto and over surfaces is a fundamental process in nature. It is present in all forms and sizes: From rivers carving through landscapes, to our blood stream transporting nutrients to cells, and even single water molecules moving through channels into these cells.

  5. 5. Interactions and dynamics in biophysical model systems

    Författare :Erik G. Brandt; Olle Edholm; Michael Odelius; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Sammanfattning : Computer simulations of simplified model systems provide understanding of how complex biological systems behave. The simulations give detailed information about the systems, with atomistic resolution, that can be used in combination with experimental knowledge to shed light on underlying physical principles.
