  1. 6. From Current Collectors to Electrodes : Aluminium Rod Structures for Three-dimensional Li-ion Micro-battery Applications

    Författare :Gabriel Oltean; Kristina Edström; Leif Nyholm; Erik Kelder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D micro-batteries; aluminium; titanium oxide; current collectros; negative electrodes; electrodepostion; electrophoretic depostion; sol-gel synthesis;

    Sammanfattning : The potential use of 3D aluminium nanorod structures as current collectors and negative electrodes for 3D Li-ion micro-batteries was studied based on the use of relatively simple and cost-effective electrochemical and sol-gel deposition techniques.Aluminium rod structures were synthesised by galvanostatic electrodeposition using commercial porous membranes as templates.

  3. 7. Direct writing with an MeV proton beam: Development and Applications

    Författare :Vaida Auzelyte; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; direct writing; beam control; Physics; Fysik; Teknik; Technological sciences; proton beam; lithography; Fysicumarkivet A:2006:Auželytė;

    Sammanfattning : This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. LÄS MER

  4. 8. Porous Silicon -an enzyme coupling matrix for micromachined reactors

    Författare :Johan Drott; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; glucose; biosensor; immobilised enzyme; porous silicon; microreactor; Mät- och instrumenteringsteknik;

    Sammanfattning : The development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. LÄS MER
