  1. 6. Fabrication and Characterization of Nano-Confined Pd Catalysts for CO Oxidation

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Alfred Larsson; [2019]
    Keywords : Catalysis Palladium Nano Nanopore CO oxidation; Physics and Astronomy;

    Abstract : During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance of these nanoporous structures.

    Author : Maria Lomaeva; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Context. The formation and evolution of the Galactic bulge and the Milky Way is still a debated subject. Observations of, e.g. READ MORE

  4. 8. Mapping the present-day chemical abundance structure of the Solar neighbourhood: O & Si

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Kristiina Verro; [2017]
    Keywords : astrophysics; stellar spectroscopy; abundance analysis; solar neighbourhood; massive stars; Galaxy; Physics and Astronomy;

    Abstract : Context. Large scale chemical abundance gradients in the Galactic disks, small-scale abundance structures, and the mean chemical abundance values in the Solar vicinity, are important constraints to Galactic chemo-dynamical formation and evolution models. READ MORE

  5. 9. Investigating inner Galactic Bulge stars through the near infrared

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Hung Shuo Su; [2017]
    Keywords : Bulge; Milky Way; Galactic Centre; infrared; spectroscopy; Physics and Astronomy;

    Abstract : Context: The formation of the Galactic Bulge is a topic of active research. There are many scenarios based on observations and Galactic evolution models. The key properties which need to be well constrained observationally are the metallicity distributions of stars and the spatial metallicity gradients. READ MORE

  6. 10. Neutron capture elements in the early Universe

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Abdalrahman Abohalima; [2017]
    Keywords : metal-poor; early Universe; neutron capture; Physics and Astronomy;

    Abstract : Metal-poor (MP) stars in the Milky Way (the Galaxy) and its satellite galaxies open a window into the earliest times in the history of the Universe, probing the chemistry of the earliest times. Recent galaxy formation simulations predict that the oldest MP stars are those on tightly bound orbits in the inner regions of a galaxy (Tumlinson 2010). READ MORE
