Energy Resolved Residual Stress Analysis with Laboratory X-Ray Sources
(2017-04-17)
It is well known that existing residual stress fields play an important role for strength and lifetime of components. Consequently there is a great interest in the availability of fast, reliable and possibly nondestructive methods for their determination. In this context, X-ray diffraction methods play an important role in technical practice as well as in scientific research. They are based on the determination of lattice strains from which residual stresses are determined applying Hooke's law with appropriate elastic ...

Bend Straightening of a Carbonitrided Gear Shaft – Consequences on Residual Stresses and Retained Austenite near the Surface
(2017-06-20)
Carbonitriding of shafts in drive technology is strongly connected with distortion. Bend straightening is an important process step in order to eliminate distortion without removing the hardened surface layer. As shown in several investigations, even for simple part geometries, bending induced stresses and plastic deformations have a strong impact not only on the residual stress state but also on the microstructure after straightening. As gear shafts become increasingly filigree and complex in their geometry, the ...

Museumsgeschichte in Kassel
(2015-07)
Die Zusammenfassungen des aktuellen Forschungsstandes und die Recherche der Bildquellen, mit deren Hilfe die zehn Stationen der Kasseler Museumsgeschichte hier vorgestellt werden, sind von Studierenden des Studiengangs Kunstwissenschaft an der Kunsthochschule der Universität Kassel in zwei aufeinander aufbauenden Projektseminaren im Sommersemester 2012 und im Wintersemester 2012/13 unter der Leitung von Prof. Dr. Alexis Joachimides erarbeitet worden.

Climatic Ageing of Components of Polymer Based Electrochromic Devices
(2013-09-09)
Combining a shading function and a polycarbonate window displays an attractive alternative to the currently employed glass roof in vehicles. However, the ageing of such a device must be investigated before any application. Therefore, our investigations focus on the ageing of the components of a polycarbonate based electrochromic device. The optical, electrical, mechanical and electrochemical properties of the ion storage layer as well as the substrate will be assessed after storage in a climate with a high humidity ...

Wie können sich die Freiburger Quartiere generationengerecht weiterentwickeln?
(2016)
Wie können sich Freiburger Quartiere weiterentwickeln und dabei die Wohn- und Lebens-bedürfnisse aller Generationen berücksichtigen? Die vorliegende stadtplanerische Studie befasst sich mit den Chancen und Herausforderungen einer Universitätsstadt, die durch ihr Angebot an Ausbildungsmöglichkeiten in Verbindung mit einer hohen Lebens- und Freizeit-qualität viele junge Menschen anzieht. Gleichzeitig und kaum beachtet, gibt es auch in die-ser Stadt eine Alterung, die es in den vorherigen Generationen in diesem Umfang ...

Spatio-temporal resolution studies on a highly compact ultrafast electron diffractometer
(2015)
Time-resolved diffraction with femtosecond electron pulses has become a promising technique to directly provide insights into photo induced primary dynamics at the atomic level in molecules and solids. Ultrashort pulse duration as well as extensive spatial coherence are desired, however, space charge effects complicate the bunching of multiple electrons in a single pulse.Weexperimentally investigate the interplay between spatial and temporal aspects of resolution limits in ultrafast electron diffraction (UED) on our ...

Greece: Austerity's unexpected allies
(2018-04)
Contrary to pre-electoral proclamations and the recent optimism of the government and its European allies, the situation since 2015 has only gotten worse. Pensions have been cut twice more (with additional cuts promised in future). More than 1 million Greeks have already suffered some form of appropriation due to debt, with another 1.7 million waiting in line - a number that represents only 70% of those indebted to the tax office. One in three face material and social deprivation (Eurostat, 2016), placing Greece third ...

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...
