21. Synthesis and characterization of palladium based carbon nanostructure-composites and their clean-energy application
Sammanfattning : Carbon nanostructures are a wide field with many applications. The use of carbon nanostructures as support in heterogeneous catalysis is a key development that led together with the use of nanoparticles to a significant cost reduction of catalysts. Catalysts designed in this way are widely applied in fuel cell technologies. LÄS MER
22. Development of a method for highly localized growth of carbon nanotubes
Sammanfattning : A method for growing carbon nanotubes on chip using highly localizedresistive heating is developed. By deliberately designing molybdenumelectrodes to be highly resistive in a very small region we create amicrometer sized hot-zone where carbon nanotubes can be grown. LÄS MER
23. CVD on Iron Powder - Using Fluidising Bed Techniques
Sammanfattning : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. LÄS MER

25. Plasma assisted technology for Si-based photonic integrated circuits
Sammanfattning : The last two decades have witnessed a large increase in capacity in telecommunication systems, thanks to the development of high bandwidth, fiber optic based networks. Nevertheless the continuing growth of Internet data traffic, fuelled by the development of numerous services like on-line commerce, video on demand, large audio/video files downloads, demands for a significant increase in the ability of the network nodes to manage incoming and outcoming data streams effectively and fast.
