  4. 2. Investigation of electrical and magnetic properties of nanoparticles and nanofibers with the aim to tailor material properties of nanocomposites

    Author : Anna Jänis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microscopy; ferrite; SiC; nanocomposite; nanowire; microwave absorbing properties; network analyzer; nanoparticle;

    Abstract : Nanocomposites are the subject of interest in this study which can be explained by the factum that using building blocks with dimensions in the nanosize range makes it possible to design and create new materials which can satisfy several functions at the same time for many applications. The applications of interest in this study belong to the microwave frequency region and for that reason a number of materials were investigated to define their microwave absorbing properties.

  6. 4. Performance Evaluation and Life Cycle Cost Analysis of the Electrical Generation Unit of a Wave Energy Converter

    Author : Pinar Tokat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The main focus of this work is the performance and the economical assessment of a radial flux generator that is used in wave power applications. The wave energy converter (WEC) used in this work is a point absorber, that is considered to move only in heave. READ MORE

  7. 5. High-Tc SQUIDs for biomedical applications: immunoassays, MEG, and ULF-MRI

    Author : Fredrik Öisjöen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes high transition temperature superconducting quantum interference devices (high-Tc SQUIDs) for magnetic immunoassays (MIAs), magnetoencephalography (MEG) and ultra-low field magnetic resonance imaging (ULF-MRI).High-Tc dc SQUID sensors were fabricated in single layers of YBa2Cu3O7−δ deposited by pulsed laser deposition and patterned using photolithography on 10×10 mm2 SrTiO3 bicrystal substrates.
