    Sammanfattning : The discovery and subsequent synthesis of metal containing fullerenes- IFS (Inorganic Fullerene-like Structures) by R. Tenne et al. has generated considerable scientific interest with great potential impact in many industrial application areas such as lubrication. LÄS MER

  4. 3. Scanning electron microscopy (SEM) analysis of tribofilms enhanced by fullerene-like nanoparticles

    Författare :István Zoltán Jenei; Stefan Csillag; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The beneficiary effects of WS2 inorganic fullerene-like nanoparticles in the lubrication industry were shown in recent years. The incorporation of the nanoparticles into lubricants (oils, greases) is however not straightforward. LÄS MER

  5. 4. Analytical Electron Microscopy Studies for Development of New Carbon Based Materials

    Författare :Staffan Wachtmeister; Stefan Csillag; Gilles Hug; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEM; EELS; CNx thin films; Carbide derived carbons; Gold deconvolution; Resolution improvement; Physics; Fysik; fysik; Physics;

    Sammanfattning : The thesis presents transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) studies of new carbon based materials synthesized with two different techniques. In the first project, nitrogen is incorporated into carbon nanostructures by supersonic cluster beam deposition (SCBD) to favor the formation of curved and cross-linked structures, ultimately aiming at creating a material with high hardness combined with good elasticity.
