  2. 1. Studies of Electrocatalytic Reactions of NADH at Mediator Modified Electrodes and of H2O2 at Peroxidase Modified Electrodes

    Author : Florentina Munteanu; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrochemistry; Elektrokemi; kinetic studies; silica gel; titanium phoshate; zirconium phosphate; NADH; redox mediator; phenolic compounds; hydrogen peroxide; electron transfer; graphite and carbon paste electrodes; peroxidase; biosensor;

    Abstract : This thesis addresses: (1) studies of direct and mediated electron transfer and kinetics of peroxidases on electrodes and the development of amperometric peroxidase-based biosenors, (2) electrochemical and kinetic studies of NADH oxidation at mediator modified electrodes. The direct and mediated electron transfer of horseradish and tobacco peroxidase were investigated on graphite electrodes by using wall-jet electrode methodology. READ MORE

  4. 2. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection

    Author : Niklas Larsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microdialysis; Liquid chromatography; Flow injection; Polyelectrolytes; Carbohydrate; Mediator; Dehydrogenase; Peroxidase; Oxidase; Enzyme; Amperometric detection; Carbon paste; Biosensor; Graphite electrode; On-line monitoring; Analytical chemistry; Analytisk kemi;

    Abstract : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. READ MORE

  5. 3. Renewable and Scalable Energy Storage Materials Derived from Quinones in Biomass

    Author : Lianlian Liu; Olle Inganäs; Niclas Solin; Daniel Brandell; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable; scalable; quinones; energy storage;

    Abstract : Currently there is an urgent need to reduce the use of fossil fuels, and efficient sustainable energy harvesters from sun and wind have been developed and are widely used for electricity generation. Storage of electrical energy is accordingly necessary to accommodate the time varying supply of wind and solar electricity. READ MORE
