  4. 17. Unraveling the structures of complex nanocrystalline materials by combining TEM and XRPD – development and application

    Author : Magdalena Ola Cichocka; Xiaodong Zou; Joke Hadermann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Structure determination; 3D electron diffraction; Complex materials; X-ray powder diffraction; Transmission electron microscopy; Inorganic Chemistry; oorganisk kemi;

    Abstract : Knowledge of the three-dimensional (3D) atomic structure of materials is essential to a fundamental understanding of their properties. The key to understanding the functionality of many materials, particularly those of commercial and industrial interest, is often hidden in the details at the nanoscale. READ MORE

  5. 18. Design and Optimization Considerations of Medium-Frequency Power Transformers in High-Power DC-DC Applications

    Author : Amin Bahmani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocrystalline-Magnetic Core; High-Power Isolated DC-DC Converter; Solid-State Transformers; Leakage Inductance; Isolation Requirements; Medium-Frequency Power Transformer;

    Abstract : Recently, power electronic converters are considered as one of the enabling technologies that can address many technical challenges in future power grids from the generation phase to the transmission and consequently distribution at different voltage levels. In contrast to the medium-power converters (5 to 100 kW) which have beenessentially investigated by the automotive and traction applications, megawatt and medium-voltage range isolated converters with a several kilohertz isolation stage,also called solid-state transformers (SST), are still in an expansive research phase.

  7. 20. On the importance of nanometer structures for implant incorporation in bone tissue

    Author : Lory Melin Svanborg; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Introduction Replacing lost teeth with dental implants is today a reliable treatment method associated with good long-term clinical results. Different surface modifications alter the surface topography at micro- and nanometer level of resolution as well as chemical properties, which have shown to be of importance for osseointegration.
