  1. 1. Improving the biocatalyst. Engineering of fungal oxidoreductases and thin-film electrodes for improvement of membraneless biofuel cells and carbohydrate biosensors

    University dissertation from Department of Chemistry, Lund University

    Author : Roberto Ortiz; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellobiose dehydrogenase; pyranose dehydrogenase; biosensor; enzymatic biofuel cell; carbon nanotubes; gold nanoparticles; direct electron transfer; flow-injection analysis; diazonium salts; self-assembled monolayers;

    Abstract : This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying the bioelement or by modifying the electrode. READ MORE

    Abstract : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. READ MORE

  3. 3. Co-Evolution of Technology, Markets and Institutions - the Case of Fuel Cells and Hydrogen Technology in Europe

    University dissertation from LU

    Author : Stian Nygaard; Lunds universitet.; Lund University.; [2008]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; fuel cells; market development; hydrogen; industrial dynamics; business development; innovation policy; Europe;

    Abstract : The birth, growth and maturity of industries, sectors and technologies have spurred the curiosity of researchers as well as managers and policy makers for a long time. Intriguingly, the emergence of a new industry is a complex process including many different actors and with a high level of uncertainty related to technology, institutions and markets facing the actors involved.

  4. 4. NFAT signaling in chronic and acute inflammation - A novel target for the treatment of diabetic vascular complications and acute pancreatitis?

    University dissertation from Vascular ET-coupling, Lund University

    Author : Anna Zetterqvist; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NFAT; vascular; diabetes; inflammation; atherosclerosis; diabetic retinopathy; acute pancreatitis; osteopontin; VCAM-1; A-285222;

    Abstract : Diabetic patients suffer from macro- and microvascular complications causing increased morbidity and mortality. How hyperglycemia provokes vascular damage remains unclear, but glucose is believed to fuel a harmful low-grade chronic inflammation of the vessel wall. READ MORE

  5. 5. Multiphysics modelling of PEM fuel cells - with reacting transport phenomena at micro and macroscales

    University dissertation from Vascular ET-coupling, Lund University
