  2. 1. Rosetta Observations of Plasma and Dust at Comet 67P

    Author : Fredrik Leffe Johansson; Anders Eriksson; Jan-Erik Wahlund; Nicolas André; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rosetta; Comets; Plasma; Langmuir Probes; Dust; Spacecraft-plasma interaction; Electrostatic Probes; Rosetta; kometer; plasma; stoft; rymdfarkost-plasma växelverkan; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : 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. READ MORE

  4. 2. Optical Dyes for Visualization of Structure and Function of Biomolecules and Biological Membranes

    Author : Maria Matson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Orientation; RNA; Lipid Membranes; Voltage-Sensitive Dyes; Binding Preferences; Cellular Localization; DNA; Spectroscopy; Spectral Properties; Lipophilic Ruthenium Complex;

    Abstract : 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. READ MORE

  5. 3. Structure and Phase Behavior of Protein Solutions

    Author : Björn Persson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistical Mechanics; Simulations; Protein Interactions; Phase Separation; Aggregation; Mutual Amplification;

    Abstract : 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. READ MORE

  6. 4. Detection of Bio-analytes with Streaming Current : From Fundamental Principles to Novel Applications

    Author : Siddharth S. Sahu; Apurba Dev; Shi-Li Zhang; Michel Calame; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Streaming current; Electrokinetic biosensor; Size and Charge effects; membrane protein profiling of extracellular vesicles; sandwich immunoassay; charge-labelled antibodies; multiplexed detection; exosome heterogeneity;

    Abstract : 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. READ MORE

  7. 5. Plasma Characterization & Thin Film Growth and Analysis in Highly Ionized Magnetron Sputtering

    Author : Jones Alami; Ulf Helmersson; James Bradley; Linköpings universitet; []
    Keywords : Highly ionized pulsed magnetron sputtering; HPPMS; HPPIMS; thin film; plasma analysis; Langmuir probe; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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). READ MORE
