  2. 6. Structural and Physical Effects of Carbon Nanofillers in Thermoplastic and Thermosetting Polymer Systems

    Author : Sanjukta Chatterjee; Svensson Svante; Ritva Serimaa; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; Composite; Carbon nanotube; Graphene;

    Abstract : Ever since the discovery of carbon nano materials like carbon nanotube (CNT) and graphene, this class of materials has gained significant attention due to their exotic properties. The principle idea of my present research project is to understand the novel improvements induced in polymer matrices with inclusion of the nanofillers. READ MORE

    Abstract : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.

    Abstract : The main purpose of this Thesis is the experimental characterization of the electronic and geometric structures of objects called clusters. A cluster consists of a finite group of bound atoms or molecules. Due to its finite size, it may present completely different properties than those of the isolated atom and the bulk. READ MORE

  7. 10. Structure and Dynamics of Core-Excited Species

    Author : Oksana Travnikova; Maria Novella Piancastelli; Svante Svensson; Denis Ceolin; Pascal Lablanqui; Uppsala universitet; []

    Abstract : In this thesis we have performed core-electron spectroscopy studies of gas phase molecular systems starting with smaller diatomic, continuing with triatomic and extending our research to more complex polyatomic ones. We can subdivide the results presented here into two categories: the first one focusing on electronic fine structure and effect of the chemical bonds on molecular core-levels and the other one dealing with nuclear dynamics induced by creation of a core hole.
