1. Nanocomposites for Use in Sliding Electrical Contacts
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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. READ MORE

2. Biomimetic Formation of Calcium Phosphate Based Nanomaterials
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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.

3. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells - Material Development and Electrical Properties
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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. READ MORE

4. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

5. Extracellular Matrix Based Materials for Tissue Engineering
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : The extracellular matrix is (ECM) is a network of large, structural proteins and polysaccharides, important for cellular behavior, tissue development and maintenance. Present thesis describes work exploring ECM as scaffolds for tissue engineering by manipulating cells cultured in vitro or by influencing ECM expression in vivo. READ MORE
