  • Morgan, Scott; Phillips, Matthew (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, Geoffrey (SPIE-Soc Photo-Optical Instrumentation Engineers, 2012)
    Nanotechnology, in particular nanophotonics, is proving essential to achieving green outcomes of sustainability and renewable energy at the production scales needed. Nanomaterials enable optimization of optical, opto-electrical, ...
  • Nicorovici, Nicolae; Mcphedran, Ross; Botten, Lindsay; Poulton, Christopher; Asatryan, Ara (Taylor and Francis, 2010)
    The local density of states (LDOS) is a function of spatial position and frequency which governs the radiation properties of sources placed within structured optical systems. We show how the enhancement or suppression of ...
  • Chen, Parry; Mcphedran, Ross; De Sterke, C; Poulton, Christopher; Asatryan, Ara; Botten, Lindsay; Steel, Michael (American Physical Society, 2010)
    In lossless periodic media, the concept of group velocity is fundamental to the study of propagation dynamics. When spatially averaged, the group velocity is numerically equivalent to energy velocity, defined as the ratio ...
  • Tomaszewska-Grzeda, A; Lojkowski, W; Godlewski, Marek; Yatsunenko, S; Drozdowicz-Tomsia, Krystyna; Goldys, Ewa; Phillips, Matthew (Polish Academy of Sciences, 2005)
    In this work we evaluate structural and optical properties of ZnO nanoparticles grown by wet chemistry method. Light emission properties of these nanoparticles are studies with cathodoluminescence and microphotoluminescence. ...
  • Drozdowicz-Tomsia, Krystyna; Goldys, Ewa; Motlan, Motlan; Zareie, Hadi; Phillips, Matthew (Amer Inst Physics, 2005)
    Multilayer GaSb/GaAs quantum-dot (QD) structures grown by atmospheric-pressure metalorganic chemical vapor deposition on semi-insulating GaAs (100) substrates with varying growth temperature of the confinement layers are ...
  • Orlic, I.; Siegele, R.; Menon, D.; Markich, S.; Cohen, D.; Jeffree, Ross; Mcphail, D.; Sarbutt, A.; Stelcer, E. (Elsevier B.V., 2002)
    Nuclear milli and microprobes at the Australian Nuclear Science and Technology Organisation (ANSTO) were used to determine lead accumulation in native Australian plants and animals. Three species of eucalypt plants ...
  • Morgan, Scott; Phillips, Matthew (IOP Publishing Ltd, 2008)
    The bandwidth and contrast of secondary electron ( SE) images obtained using variable pressure scanning electron microscopy are enhanced when a grounded Frisch grid is placed between the SE detecting anode and the negatively ...
  • Botten, Lindsay; Dossou, Kokou; Wilcox, Stuart; Mcphedran, Ross; De Sterke, C; Nicorovici, Nicolae; Asatryan, Ara (International Journal of microwave and optical Technology, 2006)
    We present an exact theory for modelling the modes of two-dimensional photonic crystals with a truly infinite cladding. It builds on our previous implementation of the fictitious source superposition method for simple point ...
  • White, Tom; De Sterke, C; Mcphedran, Ross; Botten, Lindsay (Amer Inst Physics, 2005)
    We report on very high coupling efficiencies into rod-type photonic crystal (PC) slabs with unmodified interfaces. Three-dimensional finite difference time domain simulations show that reflected powers of less than 1.5% ...
  • Du, Haiping; Zhang, Nong (Academic Press Ltd Elsevier Science Ltd, 2007)
    The paper deals with the H-infinity control problem for active vehicle suspension systems with actuator time delay. The time delay for the actuator is assumed as uncertain time-invariant but has a known constant bound. By ...
