  1. 21. Multiscale materials design of hard coatings for improved fracture resistance and thermal stability

    Författare :Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Molina; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current workhorse materials for a large number of metal cutting and wear resistant applications to fight against the extreme conditions of temperature and stress simultaneously. In spite of a high degree of sophistication in terms of material choice and microstructural design, a lower fracture resistance and limited thermal stability of the coatings remains a technological challenge in the field.

  3. 22. Magnetooptical properties of dilute nitride nanowires

    Författare :Mattias Jansson; Irina A Buyanova; Weimin Chen; Jan Eric Stehr; Hannah Joyce; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nanostructured III-V semiconductors have emerged as one of the most promising materials systems for future optoelectronic applications. While planar III-V compounds are already at the center of the ongoing lighting revolution, where older light sources are replaced by modern white light LEDs, fabricating such materials in novel architectures, such as nanowires and quantum dots, creates new possibilities for optoelectronic applications.

  4. 23. An Automotive Lane Guidance System

    Författare :Andreas Eidehall; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety; Collision avoidance; Lane guidance; State estimation; Target tracking; Kalman filter; Centralized filtering; Threat assessment; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Automotive lane guidance systems, usually referred to as Lane Keeping Aid or Lane Keeping System, are designed to prevent or warn the driver of lane departure. They typically use a buzzer to alert the driver or a steering wheel torque to actually steer the vehicle back into the center of the lane. LÄS MER

  7. 25. Nanostructured Metal Oxide Semiconductors for Functional Applications

    Författare :Anton Landström; Isabella Concina; Alberto Vomiero; Caterina Soldano; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : This thesis is about nanostructured metal oxides, their properties, and some of their applications. Semiconducting metal oxides like TiO2, ZnO,and SnO2 have a wide band gap, which means they absorb UV light andgenerate electron-hole pairs. LÄS MER
