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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Bioactivation and binding of polycyclic aromatic hydrocarbons in blood vessel endothelia

    Författare :Lizette Granberg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Polycyclic aromatic hydrocarbon; PAH; endothelial cells; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants formed by incomplete combustion of organic materials such as fossil fuels and wood. Experimental and epidemiological studies indicate that PAHs may be involved in the development of cardiovascular disease. LÄS MER

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

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

    Sammanfattning : 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.

  4. 4. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements

    Författare :Charlotte Marchand; Hogland William; Hijri Mohamed; Bramryd Torleif; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Petroleum Hydrocarbon; Trace Elements; Gentle Soil Remediation Options; Polycyclic Aromatic Hydrocarbon; Respirometry; Ecopile; Bacteria; Fungi; Miljövetenskap; Environmental Science;

    Sammanfattning : The rapid urbanization and industrialization has led to an increase of disposal petroleum hydrocarbons (PHC) and trace elements (TE) into the environment. These pollutants are considered as the most toxic contaminants in the world due to their persistence in the environment, and the long range of toxicological effects for living beings. LÄS MER

  5. 5. Residential biomass combustion - emissions of organic compounds to air from wood pellets and other new alternatives

    Författare :Maria Olsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Burning; methoxy¬phenol; benzene; stove; ecolabel; oats; wheat straw; firewood; boiler; hydrocarbon; smoke; peat;

    Sammanfattning : It is important to increase the use of biofuels for residential heating in order to decrease the use of fossil fuels and their impact on global warming. The smoke from the combustion of biomass contains a large number of compounds, which to varying degrees can affect the environment and human health. LÄS MER
