1. The Functional Microstructure of Al/AlOx/Al 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. Evaluation of UHT milk processed by direct steam injection and steam infusion technology
University dissertation from Department of Food Technology, Engineering and Nutrition, Lund UniversityAbstract : 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. Microstructure of spray dried particles at different scales of drying
University dissertation from Lund UniversityAbstract : 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. On the microstructure and mechanical properties of Mg-Al alloys
University dissertation from Jönköping : JönköpingAbstract : 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. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys
University dissertation from Linköping : Linköping University Electronic PressAbstract : 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
