  2. 1. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing

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

    Abstract : 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). READ MORE

  4. 2. Angle dependent light scattering of functional nanoparticle composites

    Author : JunXin Wang; Gunnar Niklasson; Anand Srinivason; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light scattering; nano particle; absorption; radiative transfer; Solid State Physics; Fasta tillståndets fysik;

    Abstract : Varies functional nanoparticles play crucial roles in energy- and optical- related applications. The incorporation of functional nanoparticles into non-absorbing polymers to form optical absorption and scattering thin films have attracted considerable interest due to a successful selection of particles and matrices, synergistic effects of separation and fixation of particles, and controllable layer thicknesses and structures.

  5. 3. Plasmonic Nanostructures for Optical Absorption Engineering and Hydrogen Sensing

    Author : Carl Wadell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; metal hydride; alloy nanoparticles; palladium; absorption engineering; plasmon enhanced chemistry; nanoplasmonic sensing; nanoparticle size effects; localized surface plasmon resonance; hydrogen sensing;

    Abstract : Nanoplasmonics concerns the interactions between light and metal nanoparticles. In this thesis nanoplasmonics is used in two different ways: i) to control and enhance light absorption, and ii) for optical hydrogen sensing. READ MORE

  6. 4. Nanoparticle plasmonics for solar cell applications

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

    Abstract : 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. READ MORE

  7. 5. Ceria Nanoparticle Hybrid Materials : Interfacial Design and Structure Control

    Author : Eric Johansson Salazar-Sandoval; Mats Johansson; Wolfgang Bremser; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This doctoral thesis addresses the challenge of bringing two very different materials into intimate chemical contact: inorganic metal oxide nanoparticles and acrylic polymers. In order to achieve this ambitious goal, the work has been divided into a series of more accessible tasks. READ MORE
