  2. 2. Nanoplasmonics for Absorption Engineering and Hydrogen Sensing

    Författare :Carl Wadell; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium; hydrogen storage; absorption engineering; nanoplasmonic sensing; nanosize effects; plasmon enhanced chemistry; Localized surface plasmon resonance;

    Sammanfattning : When light interacts with metallic nanoparticles smaller than its wavelength it can excite a collective oscillation of the conduction electrons that gives rise to efficient light absorption and scattering. Moreover, locally strongly enhanced electric fields are created around the particles. LÄS MER

    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. 5. Studies of catalyst sintering during operating conditions

    Författare :Pooya Tabib Zadeh Adibi; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticle sintering; operando spectroscopy; catalyst deactivation; indirect nanoplasmonic sensing; platinum; sintering kinetics;

    Sammanfattning : The damaging effect of pollutants from exhaust gas of combustion engines on the human health and the environment is well recognized. Since the 70s, the three-way catalytic converter (TWC) has substantially improved the urban air quality by simultaneous conversion of CO, NOx and unburned hydrocarbons to O2 , N2 , CO2 and H2O.
