On structural properties of magnetosome chains
Magnetotaktische Bakterien besitzen eine intrazelluläre Struktur, die Magnetosomenkette genannt wird. Magnetosomenketten enthalten Nanopartikel von Eisenkristallen, die von einer Membran umschlossen und entlang eines Zytoskelettfilaments ausgerichtet sind. Dank der Magnetosomenkette ist es …

Structural properties and phase behavior in colloidal suspensions
In this dissertation I present my research on the effective interactions of colloidal particles induced by a smaller species, as well as the structure of colloidal particles undergoing freeze casting. In this research I have used a wide variety of computational techniques in order to understand …

Electronic and structural properties of rare gas cation clusters
We study structure and ground and excited state properties of rare gas cation clusters, Rg<sup>+</sup><sub>N</sub>, for N=3-60. The main goal is to understand how the positive charge is delocalized over the cluster and the relationship between cluster geometry and delocalization. …

EVALUATING THE USE OF TURBIDIMETRY FOR STUDYING FIBRIN STRUCTURAL PROPERTIES
A fibrin fiber mesh forms the structural backbone of blood clots. Many pathological conditions result in fibrin gels with altered structural properties, so there is interest in developing rapid and accurate ways to characterize fibrin features. One method of determining the diameter and mass-length …

Relating structural properties to saltiness perception of model lipoproteic gels
… form the major source of sodium in modern diets. Structural engineering to enhance sodium release and saltiness perception is promising for sodium reduction in lipoproteic foods, which release as low as only 5% of sodium during mastication. The goal of this research is to relate structural …

Structural Properties of Genotype-Phenotype Maps: Models, Estimates and Evolution
… studies a range of questions surrounding the structural properties of GP maps. In the first part, the origin of a striking structural property shared by GP maps is studied, namely the positive correlation between the robustness and evolvability of phenotypes. By introducing analytically …

Collisional and structural properties of water ice in planet-forming regions
… In this thesis, the collisional and structural properties of ices analogous to those in planet-forming regions were studied experimentally. Low velocity collisions of millimetre and centimetre-sized crystalline ice particles (both pure water and ice composed of pure water and water …

INVESTIGATION OF THE STRUCTURAL PROPERTIES OF HAFNIUM ZIRCONIUM OXIDE THIN FILMS
… and with non-destructive read-out. Both of these properties are in favour of scaling. Ferroelectricity in HfxZr1-xO2 is attributed to the presence of the polar orthorhombic phase, formed in-situ by the transformation of the tetragonal phase. This transition is thought to occur only for …

Investigation of structural properties in biomolecular systems using synchrotron-based spectroscopies
Solid state approaches to structural properties like diffraction or microscopy techniques often cannot be applied to biomolecular systems, at least not without special postpreparation which often corrupts the desired properties of the pristine systems. In this work the capabilities of …
