1. 21. Fixation of the cemented tibial component : a radiostereometric analysis

   Författare :Hans Christian Hyldahl; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Aseptic loosening of the tibial component was the major mode for failure in early uni-(UKA) and total condylar knee arthroplasty (TKA). Metal-backing (MB) was introduced to solve the fixation problem of the tibial component, based on biomechanical experiments. LÄS MER

3. 22. Platinum(II) and Palladium (II) Complexes with Group 14 and 15 Donor Ligands. Synthesis, Structure and Substitution Mechanisms

   Författare :Ola Wendt; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mechanism; kinetics; substitution; platinum; palladium; aryl; silyl; nitrile; triphenylstibine; NMR; IR; Raman; X-ray crystallography; stopped-flow; synthesis; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : The present thesis deals with Pd(II) and Pt(II) complexes with group 14 and 15 donor ligands. Such complexes have been prepared and investigated mainly with regard to their ground state structures and the mechanism according to which they undergo substitution. LÄS MER

4. 23. A study of the autogenous Hydrogen-DRI slag and its impact on the dephosphorization of fossil-free steel at different oxygen potentials

   Författare :Joar Huss; Pär Jönsson; Du Sichen; Niklas Kojola; Chris Pistiorius; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : The present study comprises aspects related to the phosphate capacity, the dephosphorization of fossil-free steel, and the utilization of potential by-products. The focus is mainly given to the functions and impact of the autogenous H-DRI slag in the dephosphorization process and the possibility for future slag valorization. LÄS MER

5. 24. Leaching results in the assessement of slag and rock materials as construction material

   Författare :Mia Tossavainen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Sammanfattning : Extraction of rock material and ore for construction and metal production involves large quantities of wastes and by-products. Iron- and steelmaking slag has durability qualities and latent cementitious properties which are positive in construction. LÄS MER

7. 25. New Strategies for Transition Metal-mediated (Hetero)arene Functionalization

   Författare :Fredric Ingner; Lukasz Pilarski; Joanna Wencel-Delord; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis describes new approaches to achieve efficient and selective (hetero)arene derivatization using transition metals. The main focus falls on the use of strategies based on C–H activation and organo-main group reactivity to render the synthesis of various (hetero)arene derivatives more direct, efficient, regioselective and sustainable.
