1. Active cellular forces in variable mechanical microenvironments
Sammanfattning : Our bodies are immensely complex structures, with various systems, organs, and processes that are not only biochemically driven, but strongly dependent on physical mechanics. At the heart of all these processes are cells, which must generate forces to adhere, spread, differentiate, grow, and move. LÄS MER
2. Atom Probe Field Ion Microscopy of Surface Zones, Coatings and Interfaces
Sammanfattning : This thesis is focused on developingmethods for high resolution microanalysis of coatings on a substrate, andsurface zones of a bulk sample using atom probe field ion microscopy,APFIM. The APFIM technique is described and some examples of its applications to semiconductors,cemented carbides and intermetallic compounds are given. LÄS MER
3. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films
Sammanfattning : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. LÄS MER
4. Momentum exchange between light and nanostructured matter
Sammanfattning : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. LÄS MER
5. Laser cladded steel - microstructures and mechanical properties of relevance for railway applications
Sammanfattning : Owing to increased requirements like increased axle load for railway wheels and rails, new material have to be employed. However, these requirements are mostly surface related, which makes it appropriate to change only the surface layer while keeping the bulk unchanged. LÄS MER
