  • C60 Amino Acids and Peptides 

    Strom, T. Amanda (2011)
    Since the discovery of the buckyball in 1985, researchers have imagined its potential in fields ranging from materials science to medicinal chemistry. The unique size, shape and hydrophobicity of C 60 fullerene endow it ...
  • Catalytic processes simulated at nano-scale: Growth of graphitic structures and functionalized graphene explained 

    Ribas, Morgana de Avila (2011)
    Key dynamic processes at nano-scale, such as graphene hydrogenation and fluorination, and carbon nanotube (CNT) growth, cannot be observed in situ in real time. Nevertheless, such processes can be studied through complementary ...
  • Exploration of Chemical Analysis Techniques for Nanoscale Systems 

    Chang, Albert (2013-09-16)
    As the critical dimensions of many devices, especially electronics, continue to become smaller, the ability to accurately analyze the properties at ever smaller scales becomes necessary. Optical techniques, such as confocal ...
  • Graphene chemistry: Synthesis and modulation 

    Sun, Zhengzong (2012)
    This thesis investigates the chemistry of graphene from its basic synthesis to further modulation of its structure, geometry and surface chemical functional groups. A series of wet chemistry and dry chemistry experiments ...
  • Graphene Photonic Devices for Terahertz and Mid-Infrared 

    Gao, Weilu (2013-11-08)
    Graphene and other strictly two-dimensional materials are the rising stars on the horizon of material science, condensed matter physics and engineering. The richness of optical and electronic properties of graphene attract ...
  • Infrared Spectroscopy of Graphene in Ultrahigh Magnetic Fields 

    Booshehri, Layla (2012-09-05)
    Graphene – a two-dimensional honeycomb lattice of sp2-bonded carbon atoms – possesses unusual zero-gap band structure with linear band dispersions, accommodating photon-like, massless electrons that have exhibited a variety ...
  • Manipulation of Carbon Nanostructures for Multifunctional Composite Materials 

    Lomeda, Jay Rostrata (2011)
    Composite fibers comprised of 5:95 wt ratio of ultra-short single walled carbon nanotubes (US-SWCNT):polyacrylonitrile (PAN) were spun using a dry-jet wet-spinning method followed by oxidative stabilization at 285 °C. The ...
  • Optical Studies on Functionalized Graphene Systems 

    Galande, Charudatta (2014-05-05)
    Graphene, the ‘wonder material’, has received a lot of attention for its excellent electronic properties. However, the lack of a band gap severely limits its use, especially in optoelectronic applications. Therefore, opening ...
  • Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials 

    Ren, Lei (2012)
    The terahertz (THz) frequency range. 0.1 - 20 THz, exists between the microwave and infrared ranges and contains abundant information on the dynamics of charge and spin carriers in condensed matter systems. Since its advent ...
  • Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials 

    Ren, Lei; Zhang, Qi; Nanot, Sébastien; Kawayama, Iwao; Tonouchi, Masayoshi; Kono, Junichiro (2012)
    Low-dimensional carbon nanostructures, such as single-wall carbon nanotubes (SWCNTs) and graphene, offer new opportunities for terahertz science and technology. Being zero-gap systems with a linear, photon-like energy ...
  • Water Drop Tribology of Graphene and Polymer Nanocomposites 

    Cox, Paris (2013-09-16)
    Basic physics teaches us that the frictional force (lateral force) needed to move objects on surfaces are proportional to load (normal force) – Amonton’s Laws. In tribology, this force is proportional to contact area, ...
