  1. 1. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  3. 2. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dana Lüdemann; [2020]
    Keywords : aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

    Abstract : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

  4. 3. Passivation of Gallium Arsenide Nanowires for Solar Cells

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

    Author : Austin Irish; [2019]
    Keywords : nanowires; semiconductors; solar cells; photovoltaics; passivation; electronics; chemistry; polymers; hydrazine; plasma; gallium; arsenic; iii-v; epitaxy; photoluminescence; time-resolved; spectroscopy; Physics and Astronomy;

    Abstract : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. READ MORE

  5. 4. Markers in rumen gases for protein degradation in dairy cows

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Emelie Carlsson; [2017]
    Keywords : dairy cows; rumen gas; hydrogen sulfide; markers;

    Abstract : Tillförsel av kväve och fosfor i överskott till naturen leder till övergödning. En stor del av överskottet härstammar från lantbruket vilket leder till att kraven på lantbrukaren blir större. Att överutfodra korna är något man vill undvika då foderkostnaden är en av de större på gården. READ MORE
