  4. 3. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries

    Författare :Jonas Lindberg; Göran Lindbergh; Ann M. Cornell; Bryan McCloskey; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-Oxygen Batteries; Lithium Mass Transport; Oxygen Solubility; Reaction Rate Law; Reaction Mechanism; Electrode Passivation; Ultramicroelectrodes; Electrochemical Quartz Crystal Microbalance; EQCM; Chemical Engineering; Kemiteknik;

    Sammanfattning : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. LÄS MER

  5. 4. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments

    Författare :Elias Broman; Mark Dopson; Nils Risgaard-Petersen; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediment; oxygen; metatranscriptomics; metagenomics; 16S rRNA gene; RNA-seq; dead zone; re-oxygenation; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. LÄS MER

  7. 5. The evolution of ribonucleotide reductases

    Författare :Daniel Lundin; Anthony Poole; Britt-Marie Sjöberg; Christos Ouzounis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; ribonucleotide reductase; horizontal gene transfer; phylogeny; protein classification; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Ribonucleotide reductase (RNR) catalyses the transformation of RNA building blocks, ribonucleotides, to DNA building blocks, deoxyribonucleotides. This is the only extant reaction pathway for de novo synthesis of DNA building blocks and the enzyme is thus necessary for life. RNR is found in all but a few organisms. LÄS MER
