  2. 1. Specific Precipitation of Biomolecules Using Synthetic Polymers

    Author : Per-Olof Wahlund; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Polymerteknik; RNA; plasmid DNA; DNA; polyelectrolyte complexes; synthetic polymers; precipitation; affinity precipotation; Bioteknik; Polymer technology; biopolymers;

    Abstract : Purification is a very important stage in biotechnological processes. The traditionally used precipitation techniques are generally nonspecific and thus one or more chromatographic steps are normally required. There is thus a need for new approaches to improve existing techniques. READ MORE

  4. 2. The effects of planned change on Estonian morphology

    Author : Virve Raag; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Finno-Ugric languages - general; Estonian; language change; language planning; morphology; synthetic forms; analyticforms; illative singular; plural formation; superlative; Johannes Aavik; Finsk-ugriska språk - allmänt; Finno-Ugric languages; Finsk-ugriska språk; Finno-Ugric Languages; finsk-ugriska språk;

    Abstract : This work is a contribution to the fascinating and highly controversial issue of language planning, i.e. intentional human intervention in language change. Language planning, as any intentional alteration of language, is always interconnected with questions of natural development and change in language. READ MORE

  5. 3. Targeting nucleic acids in bacteria with synthetic ligands

    Author : Abbas Nikravesh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : There is a need for new antibacterial agents, and one attractive strategy is to develop nucleic acid ligands that inhibit pathogen genes selectively. Also, such ligands can be used as molecular biology probes to study gene function and nucleic acid structures. READ MORE

  6. 4. The birth of the hydrogenase : Studying the mechanism of [FeFe] hydrogenase maturation

    Author : Brigitta Németh; Gustav Berggren; Ann Magnuson; Mohamed Atta; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HydF; HydA; [FeFe] hydrogenase maturation; semi-synthetic enzymes; Biokemi; Biochemistry;

    Abstract : The [FeFe] hydrogenases are ancient metalloenzymes that catalyse the reversible interconversion between protons, electrons and molecular hydrogen. Despite the large structural variability within the [FeFe] hydrogenase family, the active site, the so called “H-cluster” is present in every representative.

  7. 5. Immobilisation of Ru-Based Molecular Catalysts for Electrochemical Water Oxidation

    Author : Andrew Howe; Sascha Ott; Javier Concepcion; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Catalysis; Metal-Organic Frameworks; Water Oxidation; Post-Synthetic Exchange; Electro-chemistry.; Kemi; Chemistry; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Artificial photosynthesis requires catalysts for efficient and selective conversions of small molecules. Molecular catalysts are advantageous to use in these instances as they offer precise control over chemical reactivity. READ MORE
