  1. 1. Dynamic Structure Discovery and Ion Transport in Liquid Battery Electrolytes

    Författare :Rasmus Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion transport mechanisms; electrolytes; dynamic structure discovery; lithium-ion batteries; statistical physics;

    Sammanfattning : The lithium-ion battery (LIB), the realisation of which earned the Nobel Prize in Chemistry 2019, has since its 1991 commercialisation become the dominant energy storage technology first for cell phones and other mobile electronics, then for power tools and other domestic appliances, and currently for electric cars and other vehicles. However, many applications would still benefit from higher power and energy densities, longer life-lengths and safer batteries. LÄS MER

  2. 2. Organizing the early project phases for frequent innovation in hypercompetitive industries

  3. 3. Structural studies of drug targets and a drug metabolizing enzyme

    Författare :Daniela Cederfelt; U. Helena Danielson; Doreen Dobritzsch; Inari Kursula; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biophysics; Protein structure; X-ray crystallography; Cryogenic electron microscopy; Enzymology; Drug discovery; Pyrimidine degradation; Biokemi; Biochemistry;

    Sammanfattning : The work presented in this thesis describes how structural information about a protein can be acquired, and how it can be used to answer scientific questions about proteins’ function, their dynamic behaviour and their interactions with other proteins or ligands.The catalytic function of the pyrimidine-degrading, drug metabolizing enzyme β-ureidopropionase (βUP) is dependent on the shift between oligomeric states.

  4. 4. Functional and structural characterizations of phytoplankton-bacteria interactions in response to environmental challenges

    Författare :Eva Sörenson; Catherine Legrand; Elin Lindehoff; Jarone Pinhassi; Sonya Dyhrman; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interactions; phytoplankton; microalgae; bacteria; communities; aquatic; diversity; functions; structure; species-specific; microbiome; core microbiome; response diversity; resilience; resource partitioning; competition; coexistence; amplicon sequencing; metatranscriptome; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Microorganisms, such as phytoplankton and bacteria, make up ≈70% of aquatic biomass and contribute 50-85% of the oxygen in Earth’s atmosphere. The microbial loop concept and the discovery of the large diversity in microbial communities acknowledge that biotic interactions between microorganisms in addition to resource competition enable the recycling of energy and nutrients in aquatic food webs.

  5. 5. Insights into dynamic covalent chemistry for bioconjugation applications

    Författare :Shujiang Wang; Oommen Varghese; Nicola Tirelli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamic covalent chemistry; reaction mechanism; hydrogel; bioconjugation; catalysis; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Dynamic covalent chemistry (DCC) is currently exploited in several areas of biomedical applications such as in drug discovery, sensing, molecular separation, catalysis etc. Hydrazone and oxime chemistry have several advantages, such as mild reaction conditions, selectivity, efficiency, and biocompatibility and therefore, have the potential to be for bioconjugation applications.
