  2. 1. Protective and Nanoporous Alumina Films Studied in situ by X-ray and Electrochemical Methods

    Author : Jonas Evertsson; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; XRR; XPS; XRF; GTSAXS; EIS; Synchrotron Radiation; Native oxide; Anodization; Anodic aluminum oxide; Nanoporous aluminum oxide; Single crystal; Aluminum alloys; in situ; Fysicumarkivet A:2018:Evertsson;

    Abstract : In this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. READ MORE

  4. 2. Nanoporous Aluminum Oxide – A Promising Support for Modular Enzyme Reactors

    Author : Marcus Kjellander; Gunnar Johansson; Gunnar Henriksson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoporous aluminum oxide; immobilized enzymes; bioreactor; Biokemi; Biochemistry;

    Abstract : Nanoporous alumina is a rather newly characterized material that so far has found limited use in the construction of bioreactors. The material has many advantages compared to conventional immobilization matrices. I have investigated its use in flow-through bioreactors. READ MORE

  5. 3. MEMS-based electrochemical gas sensors and wafer-level methods

    Author : Hithesh K Gatty; Göran Stemme; Roxhed Niclas; Anita Lloyd Spetz; KTH; []
    Keywords : MEMS; gas sensors; electrochemical; nitric oxide; hydrogen sulphide; nafion; nano;

    Abstract : This thesis describes novel microel ectromechanical system (MEMS) based electrochemical gas sensors and methods of fabrication.This thesis presents the research in two parts. In the first part, a method to handle a thin silicon wafer using an electrochemically active adhesive is described. READ MORE
