    Abstract : The research on new materials is a primary driving force for progress in human society. One of the most significant research topic nowadays is the development of new functional materials for technological applications, like perovskite implemented in solar cells, and graphene as a representative for the new 2D materials family.

  4. 22. Time resolved laser studies of gas phase and condensed phase molecules

    Author : Cecilia Lundevall; Indrek Martinsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : Different laser based techniques have been used to study lifetimes and spectra of gas phase molecules, and non-linear optical phenomena in condensed phase materials.The lifetimes of several electronically excited states of the diatomic molecules vanadium oxide, VO, zirconium sulphide, ZrS, titanium sulphide, TiS and titanium oxide, TiO have been performed by resonant two-photon ionisation spectroscopy in a molecular beam combined with a time of flight mass spectrometer.

  6. 24. In situ structural studies and gas phase visualization of model catalysts at work

    Author : Sara Blomberg; Synkrotronljusfysik; []
    Keywords : CO-oxidation; model catalysts; AP-XPS; PLIF; Pd; Rh; PdAg; Fysicumarkivet A:2017:Blomberg;

    Abstract : This thesis reports on in situ structural studies relevant to a catalytic surface during CO oxidation. The materials that have been studied are palladium, rhodium and an alloy of palladium and silver, with applications in emission cleaning by catalytic converters in vehicles. READ MORE

  7. 25. Collision- and photon-induced dynamics of complex molecular ions in the gas phase

    Author : Linda Giacomozzi; Henning Zettergren; Jason Greenwood; Stockholms universitet; []
