  1. 16. Poly-and oligothiophenes : Optical probes for multimodal fluorescent assessment of biological processes

    Författare :Karin Magnusson; Peter Nilsson; Per Hammarström; Thomas Borén; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : One interesting class of molecules in the research field of imaging biological processes is luminescent conjugated polythiophenes, LCPs. These fluorescent probes have a flexible backbone consisting of repetitive thiophene units. LÄS MER

  2. 17. Quaternized fluorene-based hydroxide exchange membranes and polymers: design, synthesis, and characterization

    Författare :Andrit Allushi; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; anion exchange membrane; hydroxide conductivity; alkaline stability; water electrolyzer; fuel cell;

    Sammanfattning : In modern society, the consumption of fossil fuels has been increasing drastically, leading to significant emissions of carbondioxide (CO2), air pollution, global warming, and political and economic imbalances. This has increased the interest inrenewable and sustainable energy sources such as wind- and hydropower, solar energy, and in energy conversion by fuel celltechnology, and water electrolyses.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; anion exchange membranes; Anion exchange membrane fuel cells; poly phenylene oxide s; hydroxide conductivity; alkaline stability; lithiation; Menshutkin reaction;

    Sammanfattning : Anion exchange membrane fuel cells (AEMFCs) are considered as one of the most important next-generation energy conversion technologies. AEMFCs convert chemical energy into useful electrical energy and have great potential forachieving high conversion efficiencies. LÄS MER

  4. 19. Structural Studies of O-Polysaccharides from Diarrhoeal Escherichia coli

    Författare :Tara Ali; Göran Widmalm; Andrej Weintraub; Lennart Kenne; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; Lipopolysaccharide; NMR; biological repeating unit; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis describes the structural analysis of O-polysaccharides from the Gram-negative bacterium Escherichia coli that is a diarrhoeal pathogen. The Escherichia coli serotypes investigated were O178, O171, O166 and O128. The methods used in these studies were nuclear magnetic resonance spectroscopy and component analysis. LÄS MER

  5. 20. Fluorescent thiophene-based ligands for detection and characterization of disease-associated protein aggregates

    Författare :Therése Klingstedt; Peter Nilsson; Per Hammarström; Henrik Zetterberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis the unique optical properties of fluorescent ligands termed luminescent conjugated oligothiophenes (LCOs) have been used to study a variety of protein aggregates associated with human protein misfolding disease. This heterogeneous group of diseases contains well known and fatal members such as Alzheimer´s and Huntington´s disease and the development of sensitive tools for the detection and characterization of protein aggregates is crucial for unravelling the complexity of these pathologies.
