  2. 16. Accurate description of heterogeneous tumors for biologically optimized radiation therapy

    Author : Johan Nilsson; Bengt Lind; Anders Brahme; Margareta Edgren; Søren Bentzen; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heterogeneous tumors; radiation therapy; biological optimization; tumor hypoxia; effective radiation sensitivity; effective radiation resistance; Radiation biology; Strålningsbiologi;

    Abstract : In this thesis, a model of tissue oxygenation is presented, that takes into account the heterogeneous nature of tumor vasculature. Even though the model is rather simple, the resulting oxygen distributions agree very well with clinically observed oxygen distributions for most tumors and healthy normal tissues. READ MORE

  7. 20. Operando X-ray Absorption Spectroscopy Studies of Methane Oxidation Catalysts

    Author : Johan Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; operando spectroscopy; XAS; palladium; heterogeneous catalysis; methane oxidation; XAFS;

    Abstract : Operando spectroscopy is an experimental method in catalysis that combines measurements of catalytic activity and selectivity with simultaneous in situ spectroscopic characterization of the catalyst. Since the structure and composition of the catalyst are probed under reaction conditions, the method can provide valuable information to elucidate the mechanism of the studied reaction. READ MORE
