  1. 11. Partial denitrification as nitrite provider for mainstream anammox

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Felix Wallin Holmin; [2020]
    Keywords : Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.

  3. 12. Energy & redox fluxes in Lactobacillus reuteri DSM 17938 on different sugars

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Katarzyna Bengtsson; [2019]
    Keywords : Energy; redox fluxes; Lactobacillus reuteri DSM 17938; different sugars; applied microbiology; teknisk mikrobiologi; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Under anaerobic condition the specific growth rate of Lactobacillus reuteri DSM 17938 on different sugars, was analyzed using spectrophotometry. Electron acceptor (fructose) supported cells to cope with poor energy recovery by re-oxidising the NADH, thus enabling ATP formation thru acetate production, while fermenting glucose via the phosphoketolase pathway (PKP) and simultaneously operating via Embden-Meyerhof pathway (EMP).

  4. 13. Stability of electron acceptor materials for organic solar cells : a work function study of C60/C70 derivatives and N2200

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Sebastian Ekhagen; [2019]
    Keywords : ;

    Abstract : Thin films of the fullerenes PC60BM and PC70BM and the non-fullerene N2200, three popular electron acceptor materials in organic photovoltaics, have been studied, using both the Kelvin probe method as well as ultraviolet photoelectron spectroscopy. With these methods the work function was measured, as well as the highest occupied molecular orbital (HOMO) onset. READ MORE

  5. 14. Isolation and genomic characterization of three PHA degrading bacteria from the marine environment

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Giulia Elli; [2019]
    Keywords : PHA; degradation of PHA; marine bacteria; sulphate reducing bacteria; SRB; SRM; biotechnology; bioteknik; Technology and Engineering;

    Abstract : The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. READ MORE

  6. 15. Electronic structure calculations of defects in diamond for quantum computing : A study of the addition of dopants in the diamond structure

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Diana Elisa Murillo Navarro; [2019]
    Keywords : Density Functional Theory; Quantum computing; Diamond; Dopants; Quantum physics; NV color center;

    Abstract : When doing computations on the negatively (positively) charged NV-center in diamond, the common procedure is to add (subtract) an electron from the system. However, when using periodic boundary conditions, this addition/subtraction of an electron from the supercell would result in a divergent electrostatic energy. READ MORE
