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

    Author : Robert Hallberg; NanoLund; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  2. 2. Nanoparticle plasmon influence on the charge carrier generation in solar cells

    Author : Carl Hägglund; Chalmers University of Technology; []
    Keywords : solar cells; finite element method; nanoparticle plasmons; photovoltaics; nanofabrication; Si; dye sensitized solar cells; localized surface plasmon resonances;

    Abstract : Global warming is a potential threat to life on earth and to human society. It is by much evidence linked to the extensive use of fossil fuels in our present energy system. Replacing the fossil fuels by alternative sources of energy poses a tremendous challenge for mankind, but is not at all undoable. READ MORE

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

    Author : Iwan Darmadi; Chalmers University of Technology; []
    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.

  4. 4. Nanoparticles : Engineering, Assembly, and Biomedical Applications

    Author : Do Kyung Kim; KTH; []
    Keywords : nanoparticle; superparamagnetism; self assembly; ;

    Abstract : This thesis deals with novel aspects through Nanotechnologyof"bottom-up"and"top-down"strategies in combination with Biotechnology as aninterdisciplinary study. The feasibility of chemically tailoredsuperparamagnetic iron oxide nanoparticles (SPION) forin-vivobiomedical applications has beendemonstrated. READ MORE

  5. 5. Engineered Nanoparticles Generation, Characterization and Applications

    Author : Maria Messing; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is predicted that novel nanometer-sized structures incorporating nanoparticles will have a considerable impact on our lives during the coming decades. Engineered nanoparticles are already found in a number of commercially available products. READ MORE
