  1. 1. Lithium-ion Behaviour in Hard Carbon Anodes: Insights from 7Li NMR Spectroscopy

    University essay from KTH/Kemi

    Author : Adina Landström; [2023]
    Keywords : NMR spectroscopy; hard carbon; anode; lithium-ion battery; spin relaxation; NMR-spektroskopi; hårt kol; anod; litiumjonbatteri; spinnrelaxation;

    Abstract : Litiumjonbatterier (LIB) är viktiga komponenter i dagens teknologi och används för att driva en mängd olika elektroniska system, allt från datorer och mobiltelefoner till bilar och flygplan. Eftersom efterfrågan på effektiv energilagring fortsätter att växa finns ett fortsatt behov för forskning och utveckling inom området. READ MORE

  3. 2. Metabolic effects of various carbohydrates and fibre in dog food

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

    Author : Fanny Bergevi; [2022]
    Keywords : dog; whole grain wheat; peeled oats; whole grain rye; metabolic profiles; metabolic pathways;

    Abstract : The lack of scientific studies regarding dog nutrition highlights the need for future studies, especially when we know the importance of food in relation to health. The variety of ingredients in commercial dog food is huge. READ MORE

  4. 3. Reindeer decrease soil carbon stocks and deplete labile soil carbon

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Josua Seitz; [2022]
    Keywords : Reindeer; SOC; soils; Finnland; 13C NMR;

    Abstract : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.

  5. 4. Mechanism of Formation of Soft Particles in Biodiesel Fuel Blends

    University essay from KTH/Materialvetenskap

    Author : Roberta Maria Fiorenza; [2020]
    Keywords : ;

    Abstract : The large environmental impact related to the use of fossil fuel has driven the shift toward renewable sourced alternatives. Fossil diesel can be nowadays replaced by biodiesel, obtained from vegetable oils and fats, mostly used as biodiesel blends. READ MORE

  6. 5. Τοwards a Synthetic Tryptophan Aminotransferase

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Kleomenis Tsimpos; [2017]
    Keywords : aminotransferase; biomimetic; catalysis; catalyst; molecular imprinting; molecularly imprinted polymer; transition state analogue.;

    Abstract : The synthesis and evaluation of a molecularly imprinted polymer has been undertaken using an oxazine-based tryptophanamide transition state analogue (TSA) as template. An efficient route to the synthesis of oxazine-based TSAs for the reaction of pyridoxamine and indole-3-pyruvic acid has been established, with yields of up to 80%. READ MORE
