  6. 4. Photoelectron spectroscopy in the vicinity of a core-ionization threshold

    Author : Stefan Sundin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : The fundamental interaction between photons and free molecules/atoms has been studied by means of soft x-ray photoelectron spectroscopy. Special interest has been paid to the non-resonant and resonant processes in the vicinity of a core-ionization threshold. READ MORE

  7. 5. 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.
