  1. 1. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions

    Author : Samira Mousavi Nik; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Grain Growth.; Interfaces; Microstructure; AlOx Tunnel Barriers; Transmission Electron Microscopy; Imaging; Spectroscopy; Superconducting Tunnel Junctions;

    Abstract : Josephson junction as a novel superconducting electronic component plays an important role in most small-scale superconducting systems. Particularly the Al/AlOx/Al tunnel junction, a high-performance junction made with a well-established microfabrication technology, is widely used as a building block of many quantum circuits.

  2. 2. Evaluation of UHT milk processed by direct steam injection and steam infusion technology

    University dissertation from Department of Food Technology, Engineering and Nutrition, Lund University

    Author : Bozena Malmgren; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sedimentation; gel formation; microstructure; TEM transmission electron microscopy; immunogold labelling; heat effects; Technological sciences; Teknik; Food and drink technology; Livsmedelsteknik; proteolysis; steam infusion; UHT milk; steam injection;

    Abstract : UHT direct steam injection and steam infusion are widely used; however there is no comparison of their impact on milk components. This study evaluates the structural changes at different steps during the UHT processing of whole milk in a full-scale UHT plant by transmission electron microscopy (TEM) and particle size measurements, and follows the enzymatic activity.

  3. 3. Microstructure of spray dried particles at different scales of drying

    University dissertation from Lund University

    Author : Marine Nuzzo; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

    Abstract : Popular Abstract in English In our society powder is found to be a common state of material. Indeed, the powder state is found to be convenient to store and transport large quantities of material. One of the major techniques to produce powder is spray drying, also for thermally sensitive materials such as foods and pharmaceuticals. READ MORE

  4. 4. On the microstructure and mechanical properties of Mg-Al alloys

    University dissertation from Jönköping : Jönköping

    Author : Haiping Cao; Högskolan i Jönköping.; Högskolan i Jönköping.; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Mg-AI; microstructure; mechanical properties; divorced degree; modeling; mould constraint; segregation band;

    Abstract : The microstructural features and the mechanical properties of binary Mg-Al alloys have been investigated by using a gradient solidification technique. Homogeneous and nearly defect-free samples were produced under well controlled cooling conditions, through which the microstructural characteristics as well as the relationships between microstructure and mechanical properties in Mg-AI alloys were precisely defined.

  5. 5. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Mohsen Sadrossadat; Linköpings universitet.; Linköpings universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si alloys; residual stresses; microstructure; microsegregation; nucleation behavior; modeling; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Cast aluminum-silicon alloys are being increasingly used in automotive and aerospace industries for critical structure applications because of their excellent castability, low density, acceptable mechanical properties and low cost. Different casting and heat treatment parameters largely affect the microstructure and residual stress of the components, which in turn, has a great impact on their mechanical properties. READ MORE
