Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

- Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : In this thesis nanocomposite materials for use in high performance electrical contacts are tested. Self mating silver as coatings on cupper substrates are the most used material combination in power connectors today. In this work two new concepts were tested. LÄS MER
- Detta är en avhandling från Luleå tekniska universitet
Sammanfattning : As a means of creating dispersed multiphase oxide structures, high-energy milling has been used for pre-treating alumina-yttria powder mixtures before pressing and sintering. Processing was performed in a planetary ball mill with steel or alumina milling tools and measured effects of the treatment have served as data for a modeling study. LÄS MER
4. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells - Material Development and Electrical PropertiesDetta är en avhandling från Luleå tekniska universitet
Sammanfattning : Solid oxide fuel cells (SOFCs) are attracting increasing interest as devices with potentialuses in decentralized and clean electricity and heat production. Several challengeswith respect to materials have to be overcome to achieve efficiencies and life-spansthat are sufficient for long-term applications. LÄS MER
5. Functional Ceramics in Biomedical Applications On the Use of Ceramics for Controlled Drug Release and Targeted Cell StimulationDetta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. LÄS MER
