  1. 11. Molecular Dynamics of the Adsorption of Organic Molecules on Organic Substrates

    Master-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Författare :Patrik Åkesson; [2013]
    Nyckelord :Molecular Dynamics; Empirical Force Field; Computational Physics; Material Science; Simulated Annealing; Organic Molecules; Sexiphenyl; Sexithiophene; LAMMPS; CHARMM; Molekyldynamik; Empiriska kraftfält; Beräkningsfysik; Materialvetenskap; Organiska molekyler; Sexifenyl; Sexitiofen; LAMMPS; CHARMM;

    Sammanfattning : A great interest has been shown for self-assembled organic nano-structures that can be used in a variety of optoelectronic applications, from element detection to home electronics. It is known from experimental research that sexiphenyl (6P) grown on muscovite mica substrate form uniaxially self-assembled nanofibers which together with sexithiophene (6T) deposited on top gives the possibility to tune their polarized emission.

  2. 12. Controlled deposition and alignment of electrospun PMMA-g-PDMS nanofibers by novel electrospinning setups

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Bashar Haseeb; [2011]
    Nyckelord :Electrospinning; nanofibers; nanofiber alignment; PMMA-g-PDMS; controlled deposition; triple electrode.;

    Sammanfattning : Electrospinning is a useful technique that can generate micro- and nano-meter sized fibers from polymer materials. Modification of the electrospinning parameters and apparatus can generate nanofibers for use in diverse applications ranging from tissue engineering to nanocomposite fabrication; however, electrospun fibers are typically collected in a random orientation and over large areas limiting their applications.

  3. 13. A comparison of SPS  and HP sintered, electroless copper plated carbon nanofibre composites for heat sink applications

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Jennifer Ullbrand; [2009]
    Nyckelord :electroless plating; SPS; spark plasma sintering; HP; hot pressing; CNF; carbon nanofibre; carbon nanofiber; heat sinks; thermal conductivity; thermal diffusivity; Cu; composite; flash technique;

    Sammanfattning : The aim of this study is to synthesize a material with high thermal conductivity and a low coefficient of thermal expansion (CTE), useful as a heat sink. Carbon nanofibres (CNF) are first coated with copper by an electroless plating technique and then sintered to a solid sample by either spark plasma sintering (SPS) or hot pressing (HP). LÄS MER
