  1. 1. Vibrational Spectroscopy of Surface Adsorbates on Metal Surfaces. Experiments and Calculations

    Author : Ragnar K Ásmundsson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio electronic structure calculations; Fermi resonance; vibrational spectroscopy; Reflection absorption infrared spectroscopy; Fourier transform infrared spectroscopy; Cu 100 and W 110 single crystal surfaces; Physics; Fysik;

    Abstract : This work deals with a detailed analysis of the vibrational spectra of methoxy (CH3O-) and ethoxy (CH3CH2O-) on W(110) and Cu(100) single crystal surfaces. By using theoretical ab initio quantum mechanical modeling, it is demonstrated that an unprecedented quantitative understanding of the vibrational frequencies of a surface adsorbate can be obtained.

  2. 2. Sulfur cycling in Swedish arable soils : a chemical perspective

    Author : Kristin Boye; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Sulfur (S) is an essential plant nutrient. Decreased S deposition in combination with a switch to high-analysis N/P-fertilizers has increased the need for S fertilization. Thus, soil research directed at understanding soil sulfur properties and processes has intensified. READ MORE

  3. 3. Development of PET radioligands synthesized from in-target produced [11C]methane

    Author : Jan Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The aim of this thesis was two-fold. The first aim was to compare the specific radioactivity (SA) of positron emission tomography (PET) radioligands synthesized from in-target produced [11C]methane ([11C]CH4) and [11C]carbon dioxide ([11C]CO2). READ MORE
