  2. 1. In situ X-Ray Spectroscopy of Ethylene Epoxidation over Ag and studies of Li-ion batteries and Cu sulfidation

    Author : Paw Kristiansen; Laurent Duda; Thorsten Schmitt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; In situ; XAS; RIXS; heterogeneous catalysis; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis is based on experiments applying synchrotron based X-ray Absorption Spectroscopy(XAS) and Resonant Inelastic X-ray Scattering (RIXS) in the soft X-ray region to energy related systems. The main work of this thesis has been to develop a reaction cell that allowed for in situ XAS and RIXS investigations of the partial epoxidation of ethylene over a Ag catalyst at 1 atm and up to 250C.

  4. 2. The morphology of polyfluorene : fullerene blend films for photovoltaic applications

    Author : Ana Sofia Anselmo; Håkan Rensmo; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science; Organic Photovoltaics; Polymer Solar Cells; Materialteknik; Materials Engineering;

    Abstract : Polymer photovoltaic systems whose photoactive layer is a blend of a semiconducting polymer with a fullerene derivative in a bulk heterojunction configuration are amongst the most successful organic photovoltaic devices nowadays. The three-dimensional organization in these layers (the morphology) plays a crucial role in the performance of the devices. READ MORE
