  1. 6. Fingerprints of light-induced molecular transients : from quantum chemical models of ultrafast x-ray spectroscopy

    Author : Jesper Norell; Michael Odelius; Sang-Kil Son; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time-resolved x-ray spectroscopy; quantum chemistry; electronic structure; multi-configurational self-consistent field; density functional theory; molecular dynamics; Born-Oppenheimer dynamics; non-adiabatic dynamics; proton-transfer; charge-transfer; solvatization; Dyson orbital; teoretisk fysik; Theoretical Physics;

    Abstract : Absorption of sunlight generates renewable electricity and powers the growth of plants, but also causes severe damage both to synthetic materials and biological tissue. The wildly varying outcomes of these light-induced processes are ultimately determined by much slighter differences in their underlying reaction pathways, induced by the transient properties of short-lived and miniscule molecules; a powerful approach to their detection and characterization is offered by ultrafast x-ray spectroscopy, with identification of spectral fingerprints and further guidance from quantum chemical models.

  2. 7. Molecular structure and dynamics of liquid water : Simulations complementing experiments

    Author : Daniel Schlesinger; Lars G. M. Pettersson; Paola Gallo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; teoretisk fysik; Theoretical Physics;

    Abstract : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.

  3. 8. Molecular Dynamics Simulations of Fluid Lipid Membranes

    Author : Erik G. Brandt; Olle Edholm; Mats Wallin; Markus Deserno; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological fluid dynamics; biomembranes; hydrodynamics; lipid bilayers; molecular dynamics; neutron spin echo;

    Abstract : Lipid molecules form thin biological membranes that envelop all living cells, and behave as two-dimensional liquid sheets immersed in bulk water. The interactions of such biomembranes with their environment lay the foundation of a plethora of biological processes rooted in the mesoscopic domain - length scales of 1-1000 nm and time scales of 1-1000 ns.

  4. 9. Molecular-dynamics simulations of polymeric surfaces for biomolecular applications

    Author : Stela Andrea Muntean; M.A.J. Michels; M.W.J. Prins; A.V. Lyulin; Technische Universiteit Eindhoven; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polystyrenes; Molecular Dynamics; Computer Simulation; Water; Molecules; Atoms; Hydrophilicity; Biosensors; Myoglobin; Physics; Fysik;

    Abstract : In-vitro diagnostics plays a very important role in the present healthcare system. It consists of a large variety of medical devices designed to diagnose a medical condition by measuring a target molecule in a sample, such as blood or urine. READ MORE

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

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

    Abstract : 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.
