1. Crack-junctions : Bridging the gap between nano electronics and giga manufacturing
Abstract : Obtaining both nanometer precision of patterning and parallel fabrication on wafer-scale is currently not possible in conventional fabrication schemes. Just as we are looking beyond semiconductor technologies for next-generation electronics and photonics, our efforts turn to new ways of producing electronic and photonic interfaces with the nanoscale.

2. Water resistance of Scots pine joints produced by linear friction welding
Abstract : Wood welding is a mechanical friction process allowing the assembly of timber without any adhesives. The process consists of applying mechanical friction, under pressure, alternately to the two wood surfaces to be welded. READ MORE

3. Rolling Contact Fatigue of Railway Rails with Emphasis on Crack Initiation
Abstract : Increased traffic density and the heavier axle loads of modern trains have led to severe problems with rolling contact fatigue (RCF) which cause initiation of surface cracks in railheads. In this thesis, a specific type of surface crack, the head check, is studied numerically with emphasis on fatigue crack initiation. READ MORE

4. Toughness of short fiber composites : an approach based on crack-bridging
Abstract : The presented work considers how to properly characterize fracture properties of short fiber composites (SFC). Associated with fracture of SFC is the creation of a comparably widespread fracture process zone. This zone develops since a number of inelastic failure mechanisms (e.g. READ MORE

5. Thermally Conductive High-Density Polyethylene Composites for Ground Heat Exchangers
Abstract : Today, the energy used for the heating and cooling of offices, shopping centres, schools, residential areas, andother buildings is as large as 50% of the total energy consumption in the world. The climate change, globalwarming, and environmental issues have forced high requirements for energy efficiency and clean energyproduction in buildings. READ MORE
