1. Rosetta Observations of Plasma and Dust at Comet 67P
Sammanfattning : In-situ observations of cometary plasma are not made because they are easy. The historic ESA Rosetta mission was launched in 2004 and traversed space for ten years before arriving at comet 67P/Churyumov-Gerasimenko, which it studied in unprecedented detail for two years. LÄS MER
2. Optical Dyes for Visualization of Structure and Function of Biomolecules and Biological Membranes
Sammanfattning : To visualize the structure and function of biomolecules and biological membranes in the cell, optical dyes are important tools where in particular fluorescent probes provide a sensitive and selective detection. When cellular compartments are investigated it is crucial that the probe selectively binds to the area of interest and not exhibits unspecific binding affinity. LÄS MER
3. Structure and Phase Behavior of Protein Solutions
Sammanfattning : The complexity of proteins is reflected in the structure of their fluids. This is seen from strongly inhomogeneous distributions about the single protein. Using molecular simulations of protein models, based on experimental structures, the present work probes the directional forces between proteins. LÄS MER
4. Detection of Bio-analytes with Streaming Current : From Fundamental Principles to Novel Applications
Sammanfattning : A biosensor based on streaming current is a new and relatively unexplored subject with significant potential. This thesis attempts to gain a deeper understanding of the governing principles, and then exploit them to further improve its performance as well as develop novel applications. LÄS MER
5. Plasma Characterization & Thin Film Growth and Analysis in Highly Ionized Magnetron Sputtering
Sammanfattning : The present thesis addresses two research areas related to film growth in a highly ionized magnetron sputtering system: plasma characterization, and thin film growth and analysis. The deposition technique used is called high power pulsed magnetron sputtering (HPPMS). LÄS MER
