  1. 1. Alkali Metal Adsorption on Metals Studied by Hiqh Resolution Core Level Spectroscopy and Low Energy Electron Diffraction

    University dissertation from Synchrotron Radiation Research

    Author : Edvin Lundgren; Lund University.; Lunds universitet.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low Energy Electron Diffraction; Physics; Core Level Spectroscopy; Surface Structures Photoelectron Emission; Single Crystal Surfaces; Alkali Adsorption; Aluminium; Metals; Alkali Metals; Fysik; LEED.; Fysicumarkivet A:1996:Lundgren;

    Abstract : Alkali metal adsorption on metals is studied by High Resolution Core Level Spectroscopy (HRCLS) and Low Energy Electron Diffraction (LEED). The studies can be divided into two parts: adsorption of alkali multilayers and alkali adsorption in the submonolayer regime. READ MORE

  2. 2. Alkali Metals and Tar in Biomass Thermochemical Conversion: Development and Application of Online Measurement Techniques

    University dissertation from Synchrotron Radiation Research

    Author : Dan Gall; Göteborgs universitet.; Gothenburg University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tar; Alkali Metals; Biomass; Thermochemical conversion; Online Measurements.;

    Abstract : Biomass is a renewable resource that can substitute the fossil-based products we depend on today. However, the conversion techniques require further improvement in order to be competitive with the traditional industry. READ MORE

  3. 3. Electronic and Geometric Structure of Phthalocyanines on Metals

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Masumeh-Nina Shariati; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; monolayer; multilayer; metal-free phthalocyanine; metal phthalocyanine; interaction; intermolecular; adsorbate-substrate; XPS; XAS; STM; DFT; alkali; metallization;

    Abstract : Adsorption of monolayers and multilayers of metal-free and metal phthalocyanines molecules on metal surfaces has been investigated using complementary microscopic and synchrotron-based spectroscopic techniques. It was observed by STM measurements that at monolayer coverage the adsorption direction of the metal-free phthalocyanine molecules with respect to the gold surface vary as a function of temperature, i.

  5. 5. PFB Air Gasification of Biomass, Investigation of Product Formation and Problematic Issues Related to Ammonia, Tar and Alkali

    University dissertation from Ingemar Odenbrand, Department of Chemical Engineering II, Lund University

    Author : Nader Padban; Lund University.; Lunds universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NH3 formation; agglomeration; thermal conversion; PNA; PAH; alkali; tar; Biomass; gasication; ammonia reduction; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Fluidised bed thermal gasification of biomass is an effective route that results in 100 % conversion of the fuel. In contrast to chemical, enzymatic or anaerobic methods of biomass treatment, the thermal conversion leaves no contaminated residue after the process. READ MORE
