Tracing the origin of oxide inclusions in continuously casted steel using stable oxygen isotopes: An interdisciplinary approach
(2001)
A detailed mineralogical, chemical, and isotope study was conducted on refractories and slags used in the continuous casting steelmaking process. The aim of this study was to trace the origin of non-metallic inclusions and ...
Untersuchung zur Kinetik der Coesit - Quarz Umwandlung unter in-situ Bedingungen mittels Synchrotronstrahlung sowie Analyse der Mikrostrukturen im Transformationsbereich mittels TEM
(2003)
Synthetischer Coesit wurde in eine Hexaeder- Hochdruck-, Hochtemperaturapparatur verbracht und die rekonstruktive Transformation Coesit-Quarz durchgeführt, um die retrograde Metamorphosepfade natürlicher Gesteine besser ...
Pyrolyse von Metalloxiden und Silikaten unter Vakuum mit konzentrierter Solarstrahlung
(2005)
In der vorliegenden Arbeit wurde untersucht, ob eine solarthermische Hochtemperaturpyrolyse von Mondgestein oder anderen Gesteinen im Vakuum zur Gewinnung von Sauerstoff prinzipiell möglich ist und welche Anforderungen ...
Cluster analysis of European surface ozone observations for evaluation of MACC reanalysis data
(2015-04-22)
The high density of European surface ozone monitoring sites offers good opportunities for investigation of the regional ozone representativeness and for evaluation of chemistry climate models. In this thesis we analyze ...
In situ observations of reaction and transport phenomena during silicate glass corrosion by fluid-cell Raman spectroscopy: Method development and applications
(2020-07-06)
Borosilicate glass is the preferred material for the immobilization of high-level nuclear waste and an important material for various industries. Silicate glasses, however, are prone to corrosion by aqueous solutions, which ......
On the importance of meteorological parameters in processes affecting the chemical composition of the tropsphere
(2022-12-22)
Investigating the interaction of meteorology and chemistry in the troposphere is important for the identification of the processes which drive the evolution of tropospheric composition in a changing climate. It does not ...
