    Abstract : Some of the biggest problems currently facing the world are closely tied to unsolved technological challenges in the material sciences. Many materials have a porous microstructure that controls their overall properties. READ MORE

  5. 18. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions

    Author : Samira Mousavi Nik; Chalmers tekniska högskola; []
    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.

  6. 19. Microstructure and Texture of Additive Manufactured Ti-6Al-4V

    Author : Magnus Neikter; Marta-Lena Antti; Johan Moverare; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; microstructure; Ti-6Al-4V; texture; Material Mechanics; Materialmekanik;

    Abstract : Additive manufacturing (AM) for metals is a manufacturing process that has increased a lot in popularity last few years as it has experienced significant improvements since its beginning, both when it comes to accuracy and deposition rates. There are many different AM processes where the energy sources and deposition methods varies. READ MORE
