    • Carbon Based Nanomaterials for Electrochemical Energy Storage Applications 

      Li, Lei (2015-04-22)
      Ever-growing energy needs, limited energy resources, and the need to decrease soaring greenhouse gas emissions have brought about an urgent demand on the pursuit of energy alternatives, includ¬ing both renewable energy ...
    • Carbon-Based Nanomaterials and their Medical Applications 

      Samuel, Errol Loïc Graeme (2015-02-06)
      The Tour lab has previously demonstrated that antibody-targeted drug-loaded carbon nanoparticles, called PEGylated hydrophilic carbon clusters (PEG-HCCs), can be utilized for cancer-specific drug delivery both in vitro and ...
    • Chemical Vapor Deposition Synthesis of Graphene-Based Materials and Chemical Modulation of Graphene Electronics 

      Yan, Zheng (2013-09-18)
      Graphene, a two-dimensional sp2-bonded carbon material, has attracted enormous attention due to its excellent electrical, optical and mechanical properties. Recently developed chemical vapor deposition (CVD) methods could ...
    • Cobalt Nanoparticles Embedded in Nitrogen-Doped Carbon for the Hydrogen Evolution Reaction 

      Fei, Huilong; Yang, Yang; Peng, Zhiwei; Ruan, Gedeng; Zhong, Qifeng; Li, Lei; Samuel, Errol L.G.; Tour, James M. (2015)
      There is great interest in renewable and sustainable energy research to develop low-cost, highly efficient, and stable electrocatalysts as alternatives to replace Pt-based catalysts for the hydrogen evolution reaction ...
    • GR-FET application for high-frequency detection device 

      Mahjoub, Akram M.; Nicol, Alec; Abe, Takuto; Ouchi, Takahiro; Iso, Yuhei; Kida, Michio; Aoki, Noboyuki; Miyamoto, Katsuhiko; Omatsu, Takashige; Bird, Jonathan P.; Ferry, David K.; Ishibashi, Koji; Ochiai, Yuichi (2013)
      A small forbidden gap matched to low-energy photons (meV) and a quasi-Dirac electron system are both definitive characteristics of bilayer graphene (GR) that has gained it considerable interest in realizing a broadly ...
    • Graphene Ambipolar Multiplier Phase Detector 

      Yang, Xuebei; Liu, Guanxiong; Rostami, Masoud; Balandin, Alexander A.; Mohanram, Kartik (2011-10)
      We report the experimental demonstration of a multiplier phase detector implemented with a single top-gated graphene transistor. Ambipolar current conduction in graphene transistors enables simplification of the design ...
    • Molecular Plasmonics: Graphene Plasmons in the Picoscale Limit 

      Lauchner, Adam (2015-08-20)
      Doped graphene supports surface plasmons in the mid- to far-infrared that are both electrically and spatially tunable. Graphene has been shown to enable greater spatial confinement of the plasmon and fewer losses than ...
    • Nanomaterials for Hydrocarbon Exploration, Acid Gas Removal and Energy Devices 

      Ruan, Gedeng (2015-04-08)
      This thesis discusses the synthesis and characterization of several different nanomaterials as well as their applications to oil and energy industries. The nanomaterials studied here include asphalt-derived high surface ...
    • Terahertz and Infrared Spectroscopy of Gated Large-Area Graphene 

      Ren, Lei; Zhang, Qi; Yao, Jun; Sun, Zhengzong; Kaneko, Ryosuke; Yan, Zheng; Nanot, Sébastien L.; Jin, Zhong; Kawayama, Iwao; Tonouchi, Masayoshi; Tour, James M.; Kono, Junichiro (2012)
      We have fabricated a centimeter-size single-layer graphene device with a gate electrode, which can modulate the transmission of terahertz and infrared waves. Using time-domain terahertz spectroscopy and Fourier-transform ...
