  1. 1. Carbon Nitride : Characterization and Protein Interactions

    Författare :Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. LÄS MER

  3. 2. Sputtered Carbon Nitride Thin Films

    Författare :Niklas Hellgren; Bernd Schultrich; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The relation between the growth conditions and the film structure and properties of reactively magnetron sputtered carbon nitride CNx (0 ≤ x ≤ 0.6) thin films has been studied. The growth of CNx films has been studied when varying the process parameters, such as substrate temperature, N2 (partial) pressure and ion flux. LÄS MER

  4. 3. Accident-tolerant uranium nitride

    Författare :Aneta Herman; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident-tolerant fuel; uranium nitride; chromium; glucose; internal sol-gel;

    Sammanfattning : After the nuclear accident at Fukushima-Daiichi in 2011, a search for alternatives to a current fuel-clad standard UO2-Zircaloy was encouraged by government and industry and novel fuel-clad systems were selected. These systems are often referred to as Accident Tolerant systems, because of an improved response to severe accidents. LÄS MER

  5. 4. Low-friction and wear-resistant carbon nitride coatings for bearing components grown by magnetron sputtering

    Författare :Konstantinos Bakoglidis; Grzegorz Greczynski; Lars Hultman; Susann Schmidt; Witold Gulbinski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon nitride; magnetron sputtering; physical vapor deposition; coatings; bearings; rolling contact fatigue; adhesion; friction; wear; transmission electron microscopy; scanning electron microscopy; x-ray photoelectron spectroscopy; coatings tribology; nanotribology;

    Sammanfattning : The scope of this thesis is the investigation of magnetron sputtered carbon nitride coatings suitable for roller bearing components. The research field of tribology of bearings focuses on minimizing friction between components by improving the lubricants. LÄS MER
