16. Molecular dynamics simulations of intermolecular mechanisms in nuclear spin relaxation
Sammanfattning : .... LÄS MER
17. Dynamics of Disordered Materials in Confined Geometries
Sammanfattning : This thesis is concerned with effects of geometrical confinement on dynamics in disordered materials in the nanoscopic range. Of particular interest is the dynamics around the liquid to glass transition. Two systems have been investigated: thin polymer films and polymer gels. LÄS MER
18. Dielectric Relaxation in Dielectric Mixtures
Sammanfattning : In this thesis dielectric properties of both ideal composite structures and polymeric composite materials were investigated. Numerical calculations were performed to simulate frequency response of interfacial polarization using the finite element method in two dimensions. LÄS MER
19. Analysis of NMR Spin-lattice Relaxation Dispersion on Complex Systems
Sammanfattning : This thesis focus on the analysis of spin-lattice NMRD relaxation profilesmeasured in various complex systems such as proteins, zeolites and ionicliquids. Proton, deuterium and fluoride T1-NMRD relaxation profiles wereobtained from a fast-field cycling (FFC) instrument. LÄS MER
20. Corrosion testing of heat exchanger tubing
Sammanfattning : Heat exchanger tubes are commonly made from stainless steel.In a heat exchanger both the process fluid and the cooling orheating media can be corrosive. It is therefore important to beable to select materials that do not suffer from corrosion.Current methods in this area, however, suffer from limitationsand shortcomings. LÄS MER
