Fast X-ray diffraction crystal size distribution analysis
(2018-09-11)Fast X-ray Diffraction Crystal Size Distribution analysis (FXD-CSD) constitutes a novel method to determine volume-based crystal size distributions (CSD) of crystalline powders or polycrystalline materials in the lower µm ... -
Microstructure of Gas Hydrates in Sedimentary Matrices
(2016-06-22)Gas hydrates (GH) are found worldwide in marine sediments and permafrost regions. The detection and quantification of gas hydrates present in marine sediments is crucial for safe oil and gas extraction, seafloor stability ... -
Extending the Search Space for Novel Physical Forms of Pharmaceuticals and Biomolecules using High-Pressure Techniques
(2016-06-17)This thesis, which is divided into two parts, describes the use of non-ambient crystallisation techniques, in particular high-pressure, to explore on one hand inclusion complex formation of cyclodextrins with drug molecules ... -
Analyse der vierperiodischen Minimalnetze
(2015-03-06)Periodic structures – e. g. crystal structures – are analyzed by means of group theory. The concept of a crystal structure is extendable to the n-dimensional space and the 4-dimensional space groups are known [Brown, ... -
Textur- und Mikrostrukturanalysen an Materialien für den direkten und indirekten Zahnersatz
(2014-03-07)Physical properties like hardness, e-modulus and thermal expansion of dental materials are supposed to be nondirectional (isotropic), although these materials can possess directional (anisotropic) properties due to their ... -
The microscopic dimension of paleoclimate in the EPICA-DML(Antarctica) deep ice core
(2013-03-12)The present work is divided into two main parts: the introductory half and the experimental chapter. Chapter 1 starts with the brief presentation of the scientific project that facilitated the development of the thesis, ... -
Formation and decomposition processes of CO2 hydrates at conditions relevant to Mars
(2008-12-10)From a thermodynamic point of view there is no argument against the existence of CO2 hydrates in the Martian regolith close to the surface. It was postulated, that CO2 hydrates may occur ... -
Strukturuntersuchungen an Methan- und Kohlenstoffdioxid-Clathrat-Hydraten
(2004-04-26)Huge quantities of gas hydrates are deposited in deep-sea sediments of ocean margins, in permafrost regions and probable in extraterrestic occurrences. Gas hydrates and in particular ...
