  2. 6. Graphene Hot-electron Transistors

    Author : Sam Vaziri; Mikael Östling; Max Lemme; Suman Datta; KTH; []
    Keywords : Graphene; hot-electron transistors; graphene base transistors; GBT; cross-plane carrier transport; tunneling; ballistic transport; heterojunction transistors; graphene integration; graphene transfer; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Graphene base transistors (GBTs) have been, recently, proposed to overcome the intrinsic limitations of the graphene field effect transistors (GFETs) and exploit the graphene unique properties in high frequency (HF) applications. These devices utilize single layer graphene as the base material in the vertical hot-electron transistors. READ MORE

  4. 7. Design and characterization of direct electron transfer based biofuel cells including tests in cell cultures

    Author : Peter Lamberg; Malmö högskola; []
    Keywords : biofuel cell; enzymatic fuel cell; direct electron transfer; cellobiose dehydrogenase; biocompatibility; enzyme kinetics; cell culture;

    Abstract : Enzymatic fuel cells (EFCs) are bioelectronic devices based on redox enzymes, which convert chemical energy into electrical energy via biochemical reactions. A major difficulty to overcome is to successfully connect (using e.g., immobilization) the enzymes to the electrode surface. READ MORE

  5. 8. Protein and polyelectrolyte layer-by-layer films: Assembly and electron transfer

    Author : Karolina Haberska; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; layer-by-layer assembly; nanoparticles; electron transfer; bioelectrocatalysis;

    Abstract : A layer-by-layer deposition technique for assembly of the three-dimensional bioelectrochemical systems, with potential applications such as sensing layers in biosensors or catalytic organisations in biofuel cells, was addressed in this thesis. Several investigations were carried out to understand and control multilayer films formation on planar surfaces, using electrochemical and ellipsometrical methods. READ MORE

  6. 9. Influence of Bridge Structures on the Electron Transfer in Donor-Acceptor Systems

    Author : Mikael Winters; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular wire; electron transfer; porphyrin; conjugated oligomer;

    Abstract : In this Thesis, porphyrin-based donor-acceptor systems have been used to study photoinduced electron transfer processes. Principally, two different sets of systems have been investigated. READ MORE

  7. 10. Microbial Electrochemical System: extracellular electron transfer from photosynthesis and respiration to electrode

    Author : Kamrul Hasan; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological photovoltaics; electron transfer; electrode; Rhodobacter capslatus; thylakoid membranes; cyanobacteria; algae; photosynthesis; light; photocurrent; electrochemistry;

    Abstract : The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to electrodes is restricted due to the insulated cellular exterior made of lipid structures. READ MORE
