    Author : Torbjörn Rander; Olle Björneholm; Gunnar Öhrwall; Maxim Tchaplyguine; Matthias Neeb; Uppsala universitet; []
    Keywords : Atomic and molecular physics; Free clusters; Electron spectroscopy; Doped clusters; Laser excitation; Alkali metals; Electronic structure; Geometric structure; X-ray photoelectron spectroscopy XPS ; Resonant Auger spectroscopy RAS ; Near-threshold x-ray absorption fine structure NEXAFS ; Ultraviolet photoelectron spectroscopy UPS ; Detuning; Ultra-fast dissociation UFD ; Sodium; Potassium; Oxygen; Bromomethane; Argon; Xenon; Krypton; Molecular field splitting; Core hole lifetime; Core excitation; Atom- och molekylfysik;

    Abstract : Atoms, molecules and clusters all constitute building blocks of macroscopic matter. Therefore, understanding the electronic and geometrical properties of such systems is the key to understanding the properties of solid state objects. READ MORE

  4. 17. Theoretical Studies on Electronic Structure, Spectra and Conductivity of Pristine and Alkali Doped Polyacetylene

    Author : Lucía Mercedes Rodrigues Monge; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; theoretical calculations; electron transfer; conductivity; polyacetylene; alkali metal; ab-initio methods; charge transport; semiempirical methods; doping;

    Abstract : The present thesis is a theoretical investigation of the electronic properties of linear polyenes to get an insight into conductive phenomena in pristine and doped polyacetylene. Conductivity in polyacetylene is a complex phenomena and cannot be treated within simple band models. READ MORE

  5. 18. Alkali Uptake and Release from Oxygen Carriers in Chemical Looping Applications: Development and Application of Reactor Systems and Measurement Techniques

    Author : Viktor Andersson; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali speciation; Biomass; Chemical looping combustion; Oxygen carriers;

    Abstract : Chemical looping combustion (CLC) of biomass is a heat and power generation technology with minimal associated costs for carbon capture, potentially resulting in negative CO2 emissions. The CLC technology utilizes fluidized beds of oxygen carrier (OC) particles to separate CO2 from the combustion air. READ MORE
