A waveguide-based lens-less x-ray microscope
(2006-09-05)A lot of effort is currently invested to realize phase contrast imaging with hard x-rays. For specimen consisting of light elements, e.g. biological samples, the induced phase shift of the ... -
Experimental study of lipid membranes: lipid domain formation and peptide aggregation.
(2006-06-22)In the presented work we have attemptted to improve our understanding of the factors which lead to the formation of lipid membrane spatial heterogeneities, caused by mixtures of different lipids and/or transmembrane peptides. ... -
The Dependence of the Evolution of Early-Type Galaxies on their Environment
(2006-06-13)This thesis describes the analysis of a data set of 121 elliptical and lenticular (S0) galaxies, located in different environments and at distances corresponding to look-back times between ... -
Hard X-ray Waveguide Optics
(2005-11-18)The thesis is about the preparation of intense hard X-ray nanobeams focusing on the use of X-ray waveguides in resonant beam coupling and front coupling geometry. -
Arrival times in quantum mechanics: Operational and quantum optical approaches
(2005-07-29)The theoretical analysis of time observables in quantum mechanics has been controversial and is still subject to debate. In the present work, a measurement-based approach to quantum arrival ... -
Freie Enthalpie binärer metallischer Legierungsschmelzen: Molekulardynamik Simulationen für NixZr1-x
(2005-01-31)A method to determine the free enthalpy of molecular dynamics simulated binary alloy melts is introduced. Here, first the entropy and free enthalpy of the ordered, intermetallic crystalline A x B 1-x - phases are ... -
Faseroptische Gemischbildungsanalyse in Otto-Motoren bei direkteinspritzenden Brennverfahren
(2005-01-12)The mixture formation process in gasoline direct injection engines is very complex and depends strongly on thermodynamic processes mainly induced by the engine geometrie. Most of the optical ... -
Anregbarkeit der Kelvin-Helmholz-Instabilität in der freien Scherströmung hinter einer scharfen Kante
(2004-11-29)The generation and compensation of instability waves in the detached free shear layer behind the trailing edge of a splitterplate that separated to regions with different flow velocities, ... -
Molecular dynamics of clathrin proteins at endocytic sites studied with evanescent-wave microscopy
(2004-10-04)Clathrin (consisting of a light chain and a heavy chain subunit) is a triskelion-shaped molecule that self-assembles into polyhedral lattices on cellular membranes. It has a pivotal role ... -
Untersuchungen zur IR-Laser-Ablation in Wasser
(2004-08-05)Pulsed mid-IR laser ablation in water is characterized by simultaneous heating and thermoelastic stress generation. In this work, a numerical model was developed to describe both the ... -
The significance of coherent flow structures for the turbulent mixing in wall-bounded flows
(2004-07-28)For the identification and characterisation of coherent flow structures in turbulent boundary layers and for the examination of the interaction processes between these structures, a flat ... -
Mechnismen der Stromunterdrückung in supraleitenden YBa2Cu3O7-d Kleinwinkelkorngrenzen
(2004-05-10)In highly textured thin films of the high-temperature superconductor YBa2Cu3O7-d (Y-123) intragranular critical current densities of some 1011 A/m2 at 4.2 Kelvin can be achieved. In contrast to this, in bicrystalline samples ... -
High Resolution Scattering of He Atoms and D<sub>2</sub> Molecules from the LiF(001) Crystal Surface
(2004-04-14)In this dissertation, a flexible, high-resolution molecular beam apparatus is described which allows surface scattering experiments over a wide range of final angles for fixed incident ... -
