  1. 1. Atomic Scale Characterization of III-V Nanowire Surfaces

    Författare :Johan Knutsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :III–V semiconductor materials; nanowire; surface; scanning tunneling microscopy; wurtzite; zinc blende; scanning tunneling spectroscopy; Fysicumarkivet A:2017:Knutsson;

    Sammanfattning : This dissertation focus on the atomic-scale characterization of the surface properties and electronic structure of III–V semiconductor nanowires (NWs). Since the early 2000s, the fabrication and characterization of III–V NWs has been a very significant topic within material science due to their potential for applications in lighting, energy harvesting, and electronics.

  3. 2. Forward Jet Production in ep-collisions at HERA

    Författare :Albert Knutsson; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forward Jets; Parton dynamics; Jets; Small-x; Low-x; Elementary particle physics; QCD; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2007:Knutsson;

    Sammanfattning : The production of forward jets has been measured in deep inelastic $ep$ collisions at HERA. The results are presented in terms of single differential cross sections as a function of the Bjorken scaling variable ($x_{Bj}$) and as triple differential cross sections $d^3 sigma / dx_{Bj}dQ^2dp_{t,jet}^2$, where $Q^2$ is the four momentum transfer squared and $p_{t,jet}^2$ is the squared transverse momentum of the forward jet.

  4. 3. Atherosclerotic Plaque Stability and Vascular Repair

    Författare :Anki Knutsson; Kärlväggsbiologi; []
    Nyckelord :atherosclerosis; diabetes; repair; inflammation; extracellular matrix;

    Sammanfattning : Myocardial infarction and stroke are two of the most common causes of death in the world, mainly caused by a rupture of an atherosclerotic plaque. A vulnerable atherosclerotic plaque is a high-risk plaque that can form a thrombus by rupture. LÄS MER

  5. 4. Shift work and coronary heart disease

    Författare :Anders Knutsson; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CHD; Public health medicine research areas; Folkhälsomedicinska forskningsområden;

    Sammanfattning : Previous research on the medical consequences of shift work has mainly been concerned with sleep disorders and gastrointestinal disturbances. Cardiovascular disease has not been clearly implicated. LÄS MER

  7. 5. Thermal stability and mechanical properties of TiAlN-based multilayer and monolithic coatings

    Författare :Axel Knutsson; Magnus Odén; Lennart Karlsson; Grégory Abadias; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis explores the thermal stability, microstructure, mechanical properties and cutting performance of multilayer and monolithic cubic TiAlN hard coatings. The aim is to increase the understanding of how the coatings’ microstructure and properties are affected by a layered structure when exposed to high temperatures. LÄS MER
