  1. 1. Nanostructure and biomolecule interactions : Characterizing the complex

    Författare :Stefan Gunnarsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanostructures; Proteins; Lipids; Protein corona; Aggregation; Sedimentation; Diffusion; Electron microscopy; Enzyme activity; Nanowires; Nanoparticles;

    Sammanfattning : This thesis presents the results of studies done on various biomolecules and their interactions with nanomaterials. The biomolecule sources are everything from purified, single proteins to the complicated mixture of blood serum and cell culture media. LÄS MER

  2. 2. Influence of surface roughness on rolling contact fatigue considering thermal elastohydrodynamic lubrication effects : Due to Corona it is not possible to attend this defense in person, instead attend via this link: https://play.kth.se/media/0_omfsppe6

    Författare :Carl-Magnus Everitt; Bo Alfredsson; Andreas Almqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact mechanics; Rolling contact fatigue; Pitting; Spalling; Slip; Thermal elastohydrodynamic.; Kontaktmekanik; Rullande kontaktutmattning; Pitting; Glidning; Termisk elastohydrodynamik.; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Rolling contacts are utilized in many technical applications, both in bearings and in the contacts between gear teeth. These components are subjected to high loads in many of their applications. The high loads causes very high contact pressures which may cause rolling contact fatigue, often denoted as pitting or spalling. LÄS MER

  3. 3. Mechanical Modelling of Powder Compaction : Due to Corona is not possible to attend this defense in person, instead attend via this link: https://play.kth.se/media/t/0_mbkr2jhi​

    Författare :Hjalmar Staf; Per-Lennart Larsson; Göran Frenning; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Cutting tool inserts, for instance used in steel machining, have the requirement to be toughand are therefore most often manufactured out of cemented carbides, using powdermetallurgy. Manufacturing components with powder metallurgy has its advantages in highproductivity and good net shape. LÄS MER

  4. 4. Engineered core : shell nanoparticles: synthesis, characterisation, and biocompatibility studies

    Författare :Carmen Mihaela Vogt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Superparamagnetic iron oxide nanoparticles (SPIONs) have emerged as promising contrast agents for Magnetic Resonance Imaging (MRI). Some SPIONs are already approved for clinical use. Coating of these nanoparticles with an additional biocompatible layer serves to improve the colloidal stability and biocompatibility. LÄS MER

  5. 5. Cerium Oxide Nanoparticles and Gadolinium Integration : Synthesis, Characterization and Biomedical Applications

    Författare :Peter Eriksson; Kajsa Uvdal; Caroline Brommesson; Xuanjun Zhang; Zhang-Jun Hu; Duncan Sutherland; Linköpings universitet; []

    Sammanfattning : A challenging task, in the area of magnetic resonance imaging is to develop contrast enhancers with built-in antioxidant properties. Oxidative stress is considered to be involved in the onset and progression of several serious conditions such as Alzheimer’s and Parkinson’s disease, and the possibility to use cerium-contained nanoparticles to modulate such inflammatory response has gained a lot of interest lately.
