1. Determination of molecular structure and order in liquid crystals by NMR
Sammanfattning : .... LÄS MER
2. Development of Novel Diffusion NMR Methods : Preclinical Applications in Colloidal Model Systems
Sammanfattning : NMR is a powerful non-invasive technique utilizing radiofrequency and gradient pulses to manipulate the spinsof atomic nuclei. In particular, diffusion NMR uses strong magnetic field gradients to label the positions of spins allowing for the measurement of translational motion of molecules in liquids. LÄS MER
3. Controlled Polymer Grafting from Nanoparticles for the Design of Dielectric Nanocomposites
Sammanfattning : The interest for polymeric nanocomposites has rapidly grown during the last decades, fuelled by the great potential and superior properties of nanoparticles (NPs). The production volumes of commercial NPs have increased exponentially during the last ten years, and the quality has been significantly improved. LÄS MER
4. Coherent Processes in Rare-Earth-Ion-Doped Solids
Sammanfattning : This thesis describes a number of coherent processes, such as quantum information processing, superradiance and electromagnetically induced transparency, which have been experimentally implemented using rare-earth-ion-doped crystals. The rare-earths are a class of elements that have in common, an atomic structure that allows for very long lifetimes as well as coherence times, both on optical transitions and on spin transitions.
