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

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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.

  3. 12. Optimering av bio-P-processen vid Västra strandens avloppsreningsverk i Halmstad

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Amanda Eriksson; [2018]
    Nyckelord :Enhanced phosphorus removal; EBPR; bio-P; wastewater treatment; PAO; avloppsteknik; Technology and Engineering;

    Sammanfattning : As eutrophication of lakes and oceans is increasing, regulations regarding phosphorus effluents becomes stricter. Consequently, the majority of Sweden’s wastewater treatment plants employs some method for phosphorus removal. LÄS MER

  4. 13. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Henrik Johansson; [2018]
    Nyckelord :Raman; Raman Spectroscopy; Raman scattering; biomass; biofuel; thermal conversion; pyrolysis; gasification; laser diagnostics; laser-induced fluorescence; LIF; energy; wood pellets; ammonia; aldehydes; ketones; formaldehyde; acetaldehyde; acetone; combustion physics; Physics and Astronomy;

    Sammanfattning : This thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. LÄS MER

  5. 14. Nucleosynthesis in accretion disks around black holes

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Neige Frankel; [2017]
    Nyckelord :accretion disk; Nucleosynthesis; black hole; high energy; white dwarf tidal disruption; Physics and Astronomy;

    Sammanfattning : Nucleosynthesis is the mechanism which produces new elements in nuclear reactions. Nuclear reaction rates are highly temperature dependant, and nuclear reactions take place in very hot environments. Current theories predict that the light elements such as hydrogen and helium were produced during the Big Bang. LÄS MER

  7. 15. The Channeling Effect in Ultra-Thin dE-E Monolithic Silicon Telescopes

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Fredrik Parnefjord Gustafsson; [2017]
    Nyckelord :dead-layer; Channelling; The Channeling effect; Plasma effect; Nucleosynthesis; Astrophysics; Ultra-thin silicon detectors; Inhomogenous Big Bang; MST; deadlayer; Pelletron; 8Li; cross-section; Kikuchi pattern; Physics and Astronomy;

    Sammanfattning : A new method has been proposed to study the low energy resonances of 8Li(alpha,n)11B at Ecm ≅ 0.5 MeV using dE-E Monolithic Silicon Telescopes (MSTs). Each telescope consists of five ultra-thin ∼1 µm (dE) silicon detector pads on a ∼500 µm (E) silicon detector. LÄS MER
