    Abstract : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. READ MORE

  5. 3. Palladium-based Nanoplasmonics for Ultrafast and Deactivation-Resistant Hydrogen Detection

    Author : Iwan Darmadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasmonic sensing; palladium hydride; palladium; polymer; localized surface plasmon resonance; Pd; nanoparticle; surfactant; hydrogen; palladium alloy; hydrogen sensor;

    Abstract : In the hydrogen economy scenario, hHydrogen gas is ispotential to be the main energy carrier in the hydrogen economy scenario in the upcoming future. It receives much attention since the reaction with oxygen generates electricity and produces only clean waterhydrogen is attractive as energy carrier since the energy produced by its reaction with oxygen only producesleaves water as by-product.

  6. 4. Aerosol Metal Nanoparticles and their Role in Particle-Assisted Growth of III–V Nanowires

    Author : Robert Hallberg; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerosol formation; III–V semiconductor materials; catalyst particles; Palladium nanoparticles; Gold nanoparticles; Spark discharge generation; MOVPE; MOCVD; Transmission electron microscopy TEM ; Phase stability; Nanoparticle deposition; Nanoparticle generation; nanoparticles characterization; Nanowire NW ; Nanowire growth;

    Abstract : Semiconductor nanowires have properties that make them potentially useful for applications in future electronic, photovoltaic, and optoelectronic devices. A powerful nanowire fabrication technique is the use of a nanoparticle as a preferential nucleation site, from which a nanowire grows. READ MORE

  7. 5. Template-Based fabrication of Nanostructured Materials

    Author : Anders Johansson; Mats Boman; Kornelius Nielsch; Uppsala universitet; []
    Keywords : Inorganic chemistry; Nanoparticles; nanotubes; anodic aluminium oxide; electroless deposition; ALD; Nb2O5; Prussian blue; palladium; copper; ion beam lithography; TiO2; SiO2; Oorganisk kemi;

    Abstract : Materials prepared on the nanoscale often exhibit many different properties compared to the same materials in their bulk-state. Interest in nanostructured materials has increased because of these properties in fields such as microelectronics, catalysis, optics and sensors. READ MORE
