  2. 1. Carbon Nitride : Characterization and Protein Interactions

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

    Abstract : 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. READ MORE

  4. 2. Development of Graphitic Carbon Nitride based Semiconductor Photocatalysts for Organic Pollutant Degradation

    Abstract : As a potential solution to the global energy and environmental pollution, design and synthesis of artificial photocatalysts with high activities have attracted increasing scientific interests worldwide. In recent years, the graphitic carbon nitride (g-C3N4) has shown new possible applications in the photocatalytic field due to its unique properties. READ MORE

  5. 3. Sputtered Carbon Nitride Thin Films

    Author : Niklas Hellgren; Bernd Schultrich; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  6. 4. Carbon based Thin Films Prepared by HiPIMS and DCMS

    Author : Susann Schmidt; Lars Hultman; Grzegorz Greczynski; Jörg Neidhardt; Linköpings universitet; []
    Keywords : ;

    Abstract : The present thesis focuses on carbon based thin films prepared by high power impulse magnetron sputtering (HiPIMS) and direct current magnetron sputtering (DCMS). The properties of such thin films can be tailored to an extensive variety; the film microstructure, for example, ranges in the presented work from fully amorphous, graphitic films to fullerene like (FL).
