  1. 21. Characterization of biological nanoparticles using evanescent field sensing

    Författare :Mattias Sjöberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; label-free; protein corona; mass quantification.; liposomes; single-particle; SPR; Waveguide scattering microscopy;

    Sammanfattning : In light of the increasingly realized importance of nanoparticle-based biological processes, in biology as well as in technological applications, there is a need of analysis methods capable of accurately quantifying different characteristics and processes involving these elusive entities. The aim of this thesis is the development and utilization of surface-based bioanalytical sensing methods for quantitative characterization of biological nanoparticles, most of which being based on surface-confined evanescent-field illumination.

  7. 25. 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
