  2. 1. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

    Author : Hans Fredriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

    Abstract : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

  4. 2. 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

  5. 3. Nanostructured carbon-based thin films : prediction and design

    Author : Cecilia Goyenola; Gueorgui K. Gueorguiev; Lars Hultman; Sven Stafström; Yury Gogotsi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon; carbon-based; thin films; fullerene-like; modeling; dft;

    Abstract : Carbon-based thin films are a vast group of materials of great technological importance. Thanks to the different bonding options for carbon, a large variety of structures (from amorphous to nanostructured) can be achieved in the process of film synthesis. READ MORE

  6. 4. Photon stimulated CVD of amorphous carbon thin films : By Mikael Lindstram

    Author : Mikael Lindstam; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; photolysis; thermal activation; CVD; amorphous carbon; modelling; kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Amorphous carbon has attracted much interest for several decades now because of its complex crystal structure and microstructure. Depending on the carbon sp2/sp3 bonding ratio, these materials yield a broad spectrum of useful properties; which can be tailored for specific applications. READ MORE

  7. 5. Synthesis and Characterization of Amorphous Carbide-based Thin Films

    Author : Matilda Folkenant; Ulf Jansson; Erik Lewin; Paul Mayrhofer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; coating; thin film; nanocomposite; sputter deposition; PVD; XPS; SEM; TEM; electrical properties; mechanical properties;

    Abstract : In this thesis, research on synthesis, structure and characterization of amorphous carbide-based thin films is presented. Crystalline and nanocomposite carbide films can exhibit properties such as high electrical conductivity, high hardness and low friction and wear. READ MORE
