  1. 1. Ionization and Fragmentation of Complex Molecules and Clusters : Biomolecules and Polycyclic Aromatic Hydrocarbons

    Author : Henrik A. B. Johansson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Thomas Schlathölter; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; fysik; Physics;

    Abstract : This work deals with ionization and fragmentation of biomolecules and polycyclic aromatic hydrocarbon (PAH) molecules. They are studied in the gas phase both as isolated molecules and as weakly bound clusters. READ MORE

  3. 3. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

    Author : Benoit Guieysse; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

    Abstract : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. READ MORE

  4. 4. Protein unfolding by interfaces and interactions between polycyclic aromatic hydrocarbons

    Author : Svetla Chakarova Käck; Chalmers University of Technology; []
    Keywords : first-principles calculations; PAH; denaturation; protein-interface interactions; van der Waals interactions; lattice models; polycyclic aromatic hydrocarbons; DFT; density functional theory;

    Abstract : In order to theoretically study large and complex systems, a variety of approaches that can be categorized loosely as top-down or bottom-up are followed. While our vision is to bridge the gap between these approaches and use them together in multiscale materials modeling, the present thesis is limited to give examples of each type of approach in the study of soft-matter systems.
