  • Cortie, Michael; Van Der Lingen, Elma (Institute of Materials Engineering Australasia Ltd, 2002)
    Although gold is the most inert of all metallic elements, it has interesting properties as a heterogeneous catalyst. There are a number of curious aspects to catalysis by gold that are currently attracting academic ...
  • Cortie, Michael; Zareie, Hadi; Ekanayake, Sobhath; Ford, Mike (IEEE-Inst Electrical Electronics Engineers Inc, 2005)
    Individual gold nanoparticles exhibit discrete capacitances of the order of 1 aF, and they can be tethered to a conductive substrate using a bi-functional monolayer of a suitable organic molecule. However the conduction, ...
  • Armstrong, Nicholas; Hoft, Rainer; Mcdonagh, Andrew; Cortie, Michael; Ford, Mike (Amer Chemical Soc, 2007)
    There has been significant work investigating the use of molecules as nanoscale rectifiers in so-called molecular electronics. However, less attention has been paid to optimizing the design parameters of molecular rectifiers ...
  • Levey, F; Cortie, Michael; Cornish, Lesley (Pergamon, 2002)
    Colour and hardness were measured on a series of alloys along the 76 wt.% Au line of the Au?Cu?Al system. Complex, non-monotonic behaviour was observed, which is shown to be correlated with microstructural changes. The ...
  • Liu, Jingquan; Wieczorek, Lech; Cortie, Michael; Mccredie, Geoff; Ford, Mike (Institute of Physics (UK), 2005)
    A colloidal suspension of hollow aluminium, cap-shaped nanoparticles ('nano-caps'_ can be conveniently produced by evaporation of aluminium onto a spin-coated layer of polystyrene nanoparticles (PSNPs), followed by sonication ...
  • Harris, Nadine; Cortie, Michael; Mcdonagh, Andrew; Ford, Mike (Iop Publishing Ltd, 2007)
    Micron-sized colloidal crystals comprised of gold nanospheres have been synthesized directly from a gold nanoparticlepermethyl methacrylate colloid by application of a 514 nm laser at 500 mW. An array of colloidal crystals ...
  • Cortie, Michael; Giddings, Jye; Dowd, Annette (Iop Publishing Ltd, 2010)
    We examine the optical properties of nanostructures comprised of titanium nitride, TiN, an electrically conducting intermetallic-like compound. This material can be deposited in the form of durable films by physical vapor ...
  • Cortie, Michael; Ford, Mike (Iop Publishing Ltd, 2007)
    We perform a computational investigation of the optical properties of nanoscale gold semi-shells and show how additional plasmon resonances develop as the shape is successively mutated from nanoshell to nano-cup, half-shell ...
  • Cortie, Michael; Stokes, Nicholas; Mcdonagh, Andrew (Elsevier, 2009)
    Here we explore the unusual plasmon resonances of crossed gold nanorod structures of varying geometries. Using numerical simulations, we show that the resonances of simple rods are hybridized and blue-shifted in the composite ...
  • Biggs, Taryn; Cortie, Michael; Witcomb, Michael; Cornish, Lesley (Johnson Matthey PLC, 2003)
    Shape memory alloys (SMAs) are materials that can change their shape at a specific temperature and are used in applications as diverse as sensors, temperature sensitive switches, force actuators, fire-safety valves, ...
  • Bai, H; Cortie, Michael; Maaroof, Abbas; Dowd, Annette; Kealley, Catherine; Smith, Geoff (Iop Publishing Ltd, 2009)
    Vanadium dioxide (VO2) undergoes a reversible metal-insulator transition, normally at similar to 68 degrees C. While the properties of continuous semi-transparent coatings of VO2 are well known, there is far less information ...
  • Pissuwan, Dakrong; Valenzuela, Stella; Cortie, Michael (Elsevier Science London, 2006)
    Nanoparticles of gold, which are in the size range 10-100 nm, undergo a plasmon resonance with light. This is a process whereby the electrons of the gold resonate in response to incoming radiation causing them to both ...
