  2. 1. Carbon-based magnetic nanomaterials

    Author : Valeria Zagaynova; Tatiana Makarova; Mauro Ricco; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; fullerene; single molecular magnet; Mn12; graphite fluoride; nanoporous carbon; molecular magnetism; magnetic properties; SQUID magnetometry; x-ray diffraction; Raman spectroscopy; Materials Science; materialvetenskap;

    Abstract : Magnetism of carbon-based materials is a challenging area for both fundamental research and possible applications. We present studies of low-dimensional carbon-based magnetic systems (fullerene-diluted molecular magnets, carbon nanotubes, graphite fluoride, and nanoporous carbon) by means of SQUID magnetometer, X-ray diffraction and vibrational spectroscopy, the latter techniques used as complementary instruments to find a correlation between the magnetic behaviour and the structure of the samples.

  5. 3. Toward Carbon based NEMS

    Author : Farzan Alavian Ghavanini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes CNT ; Nanoelectromechanical systems; and CMOS compatibility ; CNT-based switch; vertically aligned carbon nanofibers VACNF ; NEMS;

    Abstract : A systematic analysis and assessment of carbon nanotube (CNT) based NEMS switches is presented and their features are compared to typical complementary metal-oxide-semiconductor (CMOS) performance parameters. It is shown that CNT-based switches with considerably smaller leakage current compared to CMOS switches can be realized. READ MORE

  6. 4. Mechanical properties of carbon nanotubes and nanofibers

    Author : Henrik Jackman; Krister Svensson; Pavel Krakhmalev; Håkan Olin; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atomic force microscopy; bending; carbon nanotubes; deformation; scanning electron microscopy; Young s modulus; carbon nanofibers; mechanical properties; Physics; Fysik;

    Abstract : Carbon nanotubes (CNTs) have extraordinary electrical and mechanical properties, and many potential applications have been proposed, ranging from nanoscale devices to reinforcement of macroscopic structures. However, due to their small sizes, characterization of their mechanical properties and deformation behaviours are major challenges. READ MORE

  7. 5. Computational studies of graphene and single walled carbon nanotube growth and carbonaceous polymeric nanocomposites

    Author : Shayesteh Haghighatpanah; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; functionalization; carbon nanotube; Monte Carlo; tight binding; polyacrylonitrile; polyethylene; molecular mechanics; molecular dynamics.;

    Abstract : Graphene and single walled carbon nanotube (SWNT) has attracted a lot of attention in different fields of science due to its unique electrical, mechanical, and optical properties. Controlling the growth of graphene and SWNT is a very topical subject and critical for producing material with desired properties since their properties are highly dependent on their atomic structure and it is often desirable that the material contains very few or (if possible) no defects.
