    Sammanfattning : Through 270 million years of evolution, the finely tuned hierarchical structure of wood has been optimized for efficient nutrient transport and exceptional mechanical stability. Its distinctive orthotropic constitution can provide inspiration and design opportunities for the development of novel functional materials. LÄS MER

  3. 2. Self-doped Conjugated Polyelectrolytes for Bioelectronics Applications

    Författare :Erica Zeglio; Olle Inganäs; George Malliaras; Linköpings universitet; []

    Sammanfattning : Development of silicon based electronics have revolutionized our every day life during the last three decades. Nowadays Si based devices operate close to their theoretical limits that is becoming a bottleneck for further progress. LÄS MER

  5. 4. Applications of active materials

    Författare :Erik Edqvist; Greger Thornell; Bengt Lundberg; Edwin Jäger; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficient; microsystem; resonating cantilevers; microactuators; P VDF-TrFE ; surface mounting assembly; multi layers; flexible printed circuit board; conveyer; three legged; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Energy efficiency is a vital key component when designing and miniaturizing self sustained microsystems. The smaller the system, the smaller is the possibility to store enough stored energy for a long and continuous operational time. LÄS MER

  7. 5. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano

    Författare :Magnus Rahm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermodynamics; optical properties; dielectric functions; hydrides; alloy cluster expansions; alloys; nanoalloys;

    Sammanfattning : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. LÄS MER
