1. 1. Collision Induced Fragmentation of Molecules and Molecular Clusters : Knockout Driven Reactions in Fullerenes and PAHs

   Författare :Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Ulf Saalmann; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

   Sammanfattning : This licentiate thesis covers experimental and theoretical studies of the fragmentation and sub- sequent reactions of fullerenes or Polycyclic Aromatic Hydrocarbons (PAHs). I present results from experiments where atoms or ions collide with fullerenes, PAHs, or clusters of these mole- cules at energies from 100 eV up to tens of keV. LÄS MER

3. 2. Molecular Hole Punching : Impulse Driven Reactions in Molecules and Molecular Clusters

   Författare :Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Joachim Burgdörfer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAHs; Fullernes; Reactions; Clusters; Interstellar Medium; Fragmentation; Non-Statistical Fragmentation; Collisions; Experiments; Molecular Dynamics; Density Functional Theory; fysik; Physics;

   Sammanfattning : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. LÄS MER

4. 3. Carbon backbone stability of Polycyclic Aromatic Hydrocarbons

   Författare :Michael Wolf; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Stefano Bonetti; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

   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

5. 4. Energetic processing of complex molecules in the gas phase

   Författare :Michael Wolf; Henning Zettergren; Henrik Cederquist; T. Henning Schmidt; Christine Joblin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Sammanfattning : Collisions between molecules and gas phase targets often lead to various intriguing processes. Such collisions may induce fragmentation of molecules that can be divided into different subsets depending on the projectile, target, and collision energy. LÄS MER

7. 5. Morality as Practice : The Santo Daime, an Eco-Religious Movement in the Amazonian Rainforest

   Författare :Titti Kristina Schmidt; Ing-Britt Trankell; Michael Lambek; Uppsala universitet; []
   Nyckelord :Cultural anthropology; Brazil; Amazonia; Santo Daime; caboclos; environmentalism; religion; religious movements; social movements; morality; Kulturantropologi;

   Sammanfattning : This study deals with Santo Daime, a religious and environmental movement in the Brazilian Amazon. It is based on 15 months of anthropological fieldwork in the foundational centre of the Santo Daime movement, Céu do Mapiá, Heaven of Mapiá, located deep inside the Brazilian State of Amazonas.
