1. 26. Magnetic Materials for Cool Applications : Relations between Structure and Magnetism in Rare Earth Free Alloys

   Författare :Johan Cedervall; Martin Sahlberg; Paul Henry; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetism; Diffraction; X-ray scattering; Neutron Scattering; Permanent magnets; Magnetocalorics; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : New and more efficient magnetic materials for energy applications are a big necessity for sustainable future. Whether the application is energy conversion or refrigeration, materials based on sustainable elements should be used, which discards all rare earth elements. LÄS MER

4. 28. Noble Metal Catalysed Reductions and Rearrangements

   Författare :Alban Cadu; Joseph Samec; Anne Fiksdahl; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Sammanfattning : The focus of this thesis has been organometallic catalysis applied to compounds containing heteroatoms which are usually poisonous to metal catalysts, by channelling their innate reactivity advantageously. The studies described in this thesis concentrate, in the first part, on iridium catalysed asymmetric hydrogenation (papers I and II) and in the second part, on gold catalysed internal rearrangements (papers III and IV).

5. 29. Development of Mild Methods for Selective Covalent Functionalization of Graphene

   Författare :Anna Lundstedt; Grennberg Helena; Bo Wegge Laursen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polycyclic aromatic hydrocarbons; graphene models; graphite; local ionization energy surfaces; graphene functionalization; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Sammanfattning : This thesis discusses methods for the comparatively mild covalent functionalization of graphene. Several graphene models were investigated: polycyclic aromatic hydrocarbons (PAHs), chemical vapor deposition (CVD)-graphene on SiO2/Si substrate, graphite foil, graphite flakes, kish graphite and highly oriented pyrolytic graphite.
