    Sammanfattning : In this thesis I present results from Collision-Induced Dissociation (CID) experiments of Polycyclic Aromatic Hydrocarbons (PAHs) colliding with a stationary target gas at center-of-mass collision energies in the 20–200 eV range. In this energy region nuclear stopping processes dominate, i.e. LÄS MER

    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

  5. 9. Ions colliding with Polycyclic Aromatic Hydrocarbons and Fullerenes

    Författare :Fabian Seitz; Henning Schmidt; John Tanis; Stockholms universitet; []

    Sammanfattning : In this thesis a series of experiments on collisions between atomic projectile ions at keV energies and target vapors of either isolated molecules or van der Waals clusters is presented and analyzed. The atomic ions are produced in an Electron Cyclotron Resonance (ECR) ion source, accelerated and guided into the target volume. LÄS MER

  7. 10. Polycyclic aromatic hydrocarbons : DNA damage and cell signaling

    Författare :Åse Mattsson; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : Oxidative stress is a threat to our wellbeing. The formation of reactive oxygen species may result in oxidative lesions in DNA and RNA. When challenging A549 cells with 18O-labeled hydrogen peroxide, we found that RNA was between 14-25 times more sensitive to [18O]-8-oxoGuo formation than [18O]-8-oxodGuo formation in DNA. LÄS MER
