  • Solina, Danica; Cheary, Robert; Swift, Paul; Mccredie, Geoff (Elsevier Science Sa, 2003)
    An investigation has been carried out to determine the conditions required for the fabrication of stable SiO2?Pt multilayers using DC-magnetron sputtering for the Pt and RF-magnetron sputtering for the SiO2. As a preliminary ...
  • Magyar, Andrew; Lee, Jonathan; Limarga, Andi; Aharonovich, Igor; Rol, Fabian; Clarke, David; Huang, Mengbing; Hu, Evelyn (Amer Inst Physics, 2011)
    The formation of single-crystal diamond membranes is an important prerequisite for the fabrication of high-quality optical cavities in this material. Diamond membranes fabricated using lift-off processes involving the ...
  • Ahn, Jung; Wang, Guoxiu; Kim, Yong (Elsevier Inc, 2009)
    In this paper, we present a facile method to synthesize SnO2 nanofibres. Unlike the conventional CVD process for synthesizing nanofibres, the present synthesis method needs neither specific source gas nor substrates. Sn?Ag ...
  • Koos, Christian; Fujii, Masafumi; Poulton, Christopher; Steingrueber, Ralf; Leuthold, Juerg; Freude, Wolfgang (IEEE Publications, 2006)
    The accuracy of nonlinear finite-difference time-domain (FDTD) methods is investigated by modeling nonlinear optical interaction in a ring resonator. We have developed a parallelized 3-D FDTD algorithm which incorporates ...
  • Li, Kaiyang; Safavi-Naeini, Mitra; Franklin, Daniel; Petasecca, Marco; Guatelli, Susanna; Rosenfeld, Anatoly; Hutton, Brian; Lerch, Michael (IOP Publishing and SISSA, 2013)
    PETiPIX is an ultra high spatial resolution positron emission tomography (PET) scanner designed for imaging mice brains. Four Timepix pixellated silicon detector modules are placed in an edge-on configuration to form a ...
  • Malguth, Enno; Hoffmann, Axel; Phillips, Matt (Wiley - V C H Verlag GmbH & Co. KGaA, 2008)
  • Wang, Xianlong; Zeng, Zhi; Ahn, Hyojun; Wang, Guoxiu (American Institute of Physics, 2009)
    The adsorption of Li ions on boron doped graphene was investigated using a first-principles method. Our results show that, as boron doping turns graphene into an electron-deficient system, more Li ions can be captured ...
  • Chen, Pu; Poulton, Christopher; Asatryan, Ara; Steel, Michael; Botten, Lindsay; De Sterke, C; Mcphedran, Ross (Iop Publishing Ltd, 2011)
    The dispersion relation of periodic structures that include metamaterials or materials with large anomalous dispersion can give bands with infinite group velocity points. These bands do not span the entire first Brillouin ...
  • Camnpbell, S; Botten, Lindsay; De Sterke, C; Mcphedran, Ross (Taylor & Francis Ltd, 2007)
    A formulation of the modal method for multi-element dielectric lamellar diffraction gratings is presented. It combines the conventional semi-analytic Kronig-Penny formulation with a Fresnel scattering matrix approach to ...
  • Niu, N; Liu, Tsung-Li; Aharonovich, Igor; Russell, Kasey; Woolf, Alexander; Sadler, Thomas; El-Ella, Haitham; Kappers, Menno; Oliver, Rachel; Hu, Evelyn (Amer Inst Physics, 2012)
    Effective, permanent tuning of the whispering gallery modes (WGMs) of p-i-n doped GaN microdisk cavity with embedded InGaN quantum dots over one free spectral range is demonstrated by irradiating the microdisks with a ...
  • Morgan, Scott; Phillips, Matt (Amer Inst Physics, 2006)
    This work investigates the generation and detection of gaseous scintillation signals produced in variable pressure scanning electron microscopy through electron-gas molecule excitation reactions. Here a gaseous scintillation ...
  • Lutherborrow, Mark; Appavoo, Mathiyalagan; Simpson, Ann; Tuch, Bernard (Landes Bioscience, 2009)
    Previously, the insulin producing liver cell line HUH7-ins has been shown to synthesize, store and secrete insulin in response to glucose via secretory granules. The current study characterized the gene expression profile ...
  • Botten, Lindsay; Asatryan, Ara; Nicorovici, Nicolae; Mcphedran, Ross; De Sterke, C (Elsevier Science Bv, 2007)
    The usual technique for calculating the mesoscopic conductance of materials is based on Pichard's transfer matrix method [J.L. Pichard, Thesis, University of Paris, Orsay, 1984]. The essential ideas of the theory of ...
  • Chaumet, Patrick; Rahmani, Adel; Bryant, Garnett (American Physical Society, 2003)
    We present a generalization of the coupled dipole method to the scattering of light by arbitrary periodic structures. This formulation of the coupled dipole method relies on the same direct-space discretization scheme that ...
  • Fu, Haitao; Jiang, Xuchuan; Yang, Xiaohong; Yu, Aibing; Su, Dawei; Wang, Guoxiu (Springer, 2012)
    This study demonstrates a facile but effective glycothermal method to synthesize vanadium oxide nanostructures for gas sensing detection. In this method, sodium orthovanadate was first dispersed and heated in ethylene ...
  • Wang, Bei; Su, Dawei; Park, Jinsoo; Ahn, Hyojun; Wang, Guoxiu (Springer New York LLC, 2012)
    SnO2 nanoparticles were dispersed on graphene nanosheets through a solvothermal approach using ethylene glycol as the solvent. The uniform distribution of SnO2 nanoparticles on graphene nanosheets has been confirmed by ...
  • Smith, Geoff (SPIE-Soc Photo-Optical Instrumentation Engineers, 2012)
