1. Structural Studies of Large dsDNA Viruses using Single Particle Methods
Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

2. Coherent Diffractive Imaging with X-ray Lasers
Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

3. Fundamental Studies on Direct Injection Nebulisers for Sample Introduction in ICP Spectrometry : Aerosol Properties, ICP Characteristics and Analytical Performance
Abstract : The performance of different types of nebulisers: Vulkan direct injection nebuliser (Vulkan DIN), direct injection high efficiency nebuliser (DIHEN), microconcentric nebuliser coupled to cyclonic or double pass spray chamber (MCN-C or MCN-DP, respectively) was investigated and compared when used for sample introduction to ICP-MS or ICP-OES. With ICP-OES, in axial viewing mode, intensity distributions across the radius of the plasma (radial intensity profiles) were determined for different spectral lines with Esum 1. READ MORE

4. Algorithms for Coherent Diffractive Imaging with X-ray Lasers
Abstract : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. READ MORE

5. Solute exhange across the alveolo-capillary barrier
Abstract : The aim of this thesis was to study the transfer of solutes across the alveolo-capillary barrier in experimental models of alveolar surfactant dysfunction and lung injury as well as in smokers. Experimental studies were performed in anaesthetized, and mechanically ventilated animals. READ MORE
