21. Manufacturihng of heavy rings and large copper canisters by plastic deformation
Sammanfattning : Plastic deformation processes transform material fromas-received state to products meeting certain requirements inproperties, microstructure and shape. To achieve thistransformation, the relationship between material response andprocess conditions should be understood. LÄS MER
22. Synthesis and characterization of Pd nanoparticles for plastic plasmonic sensing applications
Sammanfattning : It is well known that hydrogen mixed with air forms a highly flammable mixture. There is an urgent need for selective and accurate sensors, since hydrogen very often serves as a fuel or energy storage medium. Given the fact that even the smallest leak can lead to an explosion, it is very important for sensors to be reliable and safe, i.e. LÄS MER
23. Characterisation methods and simulation of deformation and failure in metal forming processes
Sammanfattning : Tools for numerical analysis is a prerequisite in product development. Variations of the finite element method is widely used for simulation of metal manufacturing processes, for example sheet metal forming and hot stamping. LÄS MER
24. Prediction of springback in sheet metal forming: with emphasis on material modeling
Sammanfattning : The prediction of springback is probably the area in sheet metal forming simulation, where the least success has been achieved in terms solution accuracy. The springback is caused by the release of the residual stresses in the work piece after the forming stage. LÄS MER
25. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles
Sammanfattning : The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. LÄS MER
