  2. 1. Electrically Induced Debonding of Adhesives

    Author : Simon Leijonmarck; Göran Lindbergh; Mats Johansson; Jinshan Pan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

    Abstract : Electrically induced adhesive debonding is a process where an adhesive can be debonded at command with help of an applied voltage. To make this process function, the adhesive is  bonded between two metal substrates. In this study an epoxy adhesive is adhered between two aluminium foils forming a laminate structure. READ MORE

  4. 2. Solid Oxide Fuel Cell Modeling at the Cell Scale - Focusing on Species, Heat, Charge and Momentum Transport as well as the Reaction Kinetics and Effects

    Author : Martin Andersson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOFC; anode-supported; modeling; CFD; charge species heat momentum transport; electrochemical internal reforming reactions; TPB; area-to-volume ratio; COMSOL Multiphysics;

    Abstract : Fuel cells are electrochemical devices that directly transform chemical energy into electricity. They are promising for future energy systems, since they are energy efficient, able to use renewable fuels and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases.

  5. 3. Preparation and Characterization of Electrochemical Devices for Energy Storage and Debonding

    Author : Simon Leijonmarck; Göran Lindbergh; Ann Cornell; Leif Nyholm; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesives; carbon fiber; debonding; delamination; electropolymerization; flexible battery; lithium-ion battery; paper battery;

    Abstract : Within the framework of this thesis, three innovative electrochemical devices have been studied. A part of the work is devoted to an already existing device, laminates which are debonded by the application of a voltage. READ MORE

  6. 4. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

    Author : Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
    Keywords : Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

    Abstract : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. READ MORE
