    Sammanfattning : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. LÄS MER

  3. 2. Optical Functionalization of Transparent Wood Biocomposites

    Författare :Martin Höglund; Lars Berglund; Sergei Popov; Jonsson Magnus; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transparent wood; biocomposite; optical scattering; interfaces; dye laser; organic dye; plasmonic; nanoparticle;

    Sammanfattning : Transparent wood (TW) biocomposites combines load-bearing properties with high transmittance of light. TW consists of a reinforcing wood substrate that has been infiltrated with a polymer matrix. TW can be combined with additives so that new multifunctional materials are obtained. LÄS MER

  4. 3. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing

    Författare :Christoph Langhammer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticle; hydrogen storage; aluminum; hydrogen sensing; localized surface plasmon resonance; platinum; nanostructure; palladium; nanoparticle plasmon;

    Sammanfattning : The interaction of light with sub-wavelength noble metal nanoparticles and nanostructures has developed into one of the most vibrant themes of nanoscience during the past decade. The optical properties of metal nanoparticles are dominated by so-called nanoparticle plasmons or localized surface plasmon resonances (LSPR). LÄS MER

  5. 4. Nanoparticle plasmonics for solar cell applications

    Författare :Viktoria Gusak; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; titanium dioxide.; Localized Surface Plasmon Resonance; mesoporous material; Plasmonic nanoparticle; amorphous hydrogenated Silicon; solar cell; Dye-Sensitized Solar Cell; diffusion;

    Sammanfattning : The energy demand of society increases rapidly, while the main source of today’s energy, the fossil fuels, eventually will be depleted and also poses environmental and climate hazards (though the global warming). Therefore there is a need for alternative, renewable energy sources, and solar photovoltaics (solar cells) will play an important role as one of them. LÄS MER

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

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

    Sammanfattning : 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.
