  1. 1. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Mohamad Abd Elwadood; [2023]
    Nyckelord :Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

    Sammanfattning : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. LÄS MER

  3. 2. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Ismail Yussuf Hassan; [2023]
    Nyckelord :graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

    Sammanfattning : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

  5. 4. Protein Recovery from Alkaline Extracts: A Comparative Analysis of Isoelectric Precipitation and Ultrafiltration

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Anjay Sharma; [2023]
    Nyckelord :Rapeseed cake; Brewers spent grains; Protein recovery; Ultrafiltration; Alkaline extraction; Food engineering; Technology and Engineering;

    Sammanfattning : Proteins are one of three macro-components of a diet. An increasing demand for products that can be a complete protein source exists. The vulnerability of the current food system towards environmental impacts and the inability to keep up with the rising population has shifted the focus on valorising underutilised by-products of the food industry.

  7. 5. Change in stability and characteristics of different sunflower press cake mixtures during fermentation with Lactiplantibacillus plantarum

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sarah Nachemson Ekwall; [2022]
    Nyckelord :Sunflower; press cake; fermentation; Lactoplantibacillus plantarum; food technology; Agriculture and Food Sciences;

    Sammanfattning : Food's impact on the climate is getting more awareness, leading to an interest in finding possible solutions. One such is to use waste products to create new products. Sunflower press cake (SFPC) is a waste product from sunflower oil production with great potential because of its high protein content. LÄS MER
