3. 12. Silicon nitride based coatings for biomedical implants

   Författare :Charlotte Skjöldebrand; Cecilia Persson; Håkan Engqvist; Julia Shelton; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon nitride; ceramic coating; deposition; PVD; dissolution; biocompatibility;

   Sammanfattning : Silicon nitride-based coatings have been proposed as a means to reduce the release of metal ions and debris from metallic implants. This reduction in combination with the biocompatible debris from silicon nitride could result in a less adverse immune response. LÄS MER

4. 13. Phase formation in multicomponent films based on 3d transition metals

   Författare :Smita Gangaprasad Rao; Per Eklund; Arnaud Le Febvrier; Denis Music; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The need for materials that enhance life span, performance, and sustainability has propelled research in alloy design from binary alloys to more complex systems such as multicomponent alloys. The CoCrFeMnNi alloy, more commonly known as the Cantor alloy, is one of the most studied systems in bulk as well as thin film. LÄS MER

5. 14. 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.

7. 15. On the chemistry and stability of ternary precipitates in microalloyed steels

   Författare :Jan Strid; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

   Sammanfattning : Light optical-, electron microscopy and Charpy-V-notch testing is used to characterize a number of different Ti-microalloyed steels, containing various alloying additions including high and low levels of nitrogen, and a Nb-steel is used as a comparison. The steels are studied in both the as-received and weld simulated conditions. LÄS MER
