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

    Författare :Hans Fredriksson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

    Sammanfattning : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. LÄS MER

  4. 3. Carbon nanotube/MF composites

    Författare :Liliana Licea Jimenez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocomposites; carbon nanotubes; melamine-formaldehyde;

    Sammanfattning : A new generation of composites, frequently referred to as nanocomposites, are making research and engineering impact worldwide. Particularly, the incorporation of carbon nanotubes (CNT) into polymers is attractive, due to the generally good processability of polymers and the unprecedented properties of nanotubes. LÄS MER

  5. 4. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets
