  1. 1. Second generation of Glucose Biosensors : Biofuel cells and Neurotransitters

    Detta är en avhandling från Media-Tryck, Lund University, Sweden

    Författare :NAJAT BEDEN; Lunds universitet.; Lund University.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GDH; PDH; GOx; CDH; mediated electron transfer MET; Os-polymer; Man-Os VI tmen; PVPOs II -Chitosan; Au-NPs-MWCNTS; enzymatic biosensors; non-enzymatic sensor; DA-sensor; Multi-analyte sensor; DA; AA; UA;

    Sammanfattning : Different FAD dependent GDH enzymes together with the Os-redox polymer Os(4,4′-dimethyl-2,2′-bipyridine)2(PVI)10Cl]+ and a modified graphite electrode was shown to have distinct selectivity and high turnover rates towards glucose. The results of this study suggest that such electrodes may be applied either for glucose determination or as bioanodes in glucose biofuel cells. LÄS MER

  2. 2. Circadian Rhythms in Moth Sex Pheromone Communication

    Detta är en avhandling från Chemical Ecology and Ecotoxicology, Department of Biology, Lund University

    Författare :Germund von Wowern; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; växtparasitologi; Entomologi; plant parasitology; Entomology; Ecology; Ekologi; locomotor activity; social synchronisation; PDH; corazonin; PBAN; pheromone response; sex phermone; Lepidoptera; Ryggradslösa djurs fysiologi; calling behaviour; circadian rhythm;

    Sammanfattning : Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephestia kuehniella.

  3. 3. Assessment and Some Improvements of Hybrid RANS-LES Methods

    Detta är en avhandling från Chemical Ecology and Ecotoxicology, Department of Biology, Lund University

    Författare :Sebastian Arvidson; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; hybrid RANS-LES; zonal RANS-LES; embedded LES; PDH-LRN; log-layer mismatch; LES length scale; shock boundary-layer interaction;

    Sammanfattning : Motivated by numerical analysis of a shock/boundary-layer interacting (SBLI) flow in a duct, where some typical existing hybrid RANS-LES methods become awkward to give accurate predictions of the shock-induced corner separation bubble, a new hybrid RANS-LES method, has been proposed. The model is based on a low-Reynolds-number (LRN) $k-\omega$ RANS model, which is one of the few models that are capable of giving reasonable predictions for the SBLI flow in RANS computations.

    Detta är en avhandling från Department of Chemistry, Lund University

    Författare :MNadeem Zafar; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER
