  1. 1. A Study of Factors Affecting the Particle Size for Water Atomised Metal Powders

    Author : Fredrik Persson; Pär Jönsson; Anders Eliasson; Ioannis Arvanitidis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water atomisation; metal powders; particle size; modelling; viscosity; surface tension;

    Abstract : The production of metal powders by water atomisation is a well established process, which can be used to produce a wide range of particle sizes. A careful control of the particle size distribution is necessary, to atomise powders with a high quality and at a low production cost. READ MORE

  2. 2. A Study of Parameters and Properties Influencing the Size, Morphology and Oxygen Content of Water Atomized Metal Powders

    Author : Fredrik Persson; Pär Jönsson; Christopher Neil Hulme; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The production of metal powders by water atomization is a well-established process, which can be used to produce a wide range of particle sizes for different applications. In general, there is a lack of detailed knowledge about what process parameters that affect the powder properties for water atomized metal powders. READ MORE

  3. 3. Fast dynamics and measurements of single-charge devices

    Author : Fredrik Persson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resonator; single-electron box; superconducting devices; decoherence; quantum capacitance; Sisyphus resistance; transmon; single-Cooper-pair box; qubit; rf-reflectometry;

    Abstract : In this thesis we present measurements on several different devices, including the single-Cooper-pair box (SCB), the single-electron box, tunable superconducting resonators and so called transmon qubits.By exploiting the quantum capacitance of the SCB, its state was measured by embedding the box in a radio-frequency resonator.

  4. 4. Studies of Fusion Oncogenes and Genomic Imbalances in Human Tumors

    Author : Fredrik Persson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer genetics; fusion oncogene; gene amplification; array CGH; PLAG1; HMGA2; FGFR1; MDM2; pleomorphic adenoma; carcinoma ex pleomorphic adenoma; liposarcoma;

    Abstract : Cancer is a genetic disease caused by mutations and chromosome rearrangements affecting oncogenes and tumor suppressor genes in particular. Molecular analyses of recurrent translocations in hematological disorders, as well as in certain solid tumor types, have shown that they frequently result in fusion oncogenes. READ MORE
