In-situ light scattering at neutron beam lines - experiences made and challenges ahead
German French Meeting at MLZ, GarchingGarching, Germany, 14 May 2019 - 14 May 20192019-05-142019-05-14
What is often well established at many synchrotron beam lines is still in the development phase at neutron beam lines: In-situ light scattering techniques. The science case for in-situ light scattering at neutron instruments lies mostly in the limited reproducibility of sample preparation and stability of the samples over time. [...]

Magnetische Adatome und Nanostrukturen auf Metalloberflächen
[Juel-3791]
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3791, IV, 140 p. ()
We present ab-initio electronic structure calculations of the electronic propertiesof impurities on metallic surfaces in the framework of the local density approximationbased on the Greens function approach proposed by Korringa, Kohn and Rostoker(KKR). Motivated by the results of scanning tunneling microscope experiments(STM) of Cr-atoms on the (001) surface of Iron, we study in the first part of thisreport the properties of $\textit{3d}$-impurities on the Fe(001) surface.

Strukturelle Dynamik von photosensitiven Proteinen
[Juel-3790]
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3790, 117 p. ()
The thesis presented here describes the application of intense, pulsed X-rays from a synchrotron to the investigation of biochemical reactions triggered by light. The workincludes contributions to the instrumentation of a beamline and experiments with the proteins myoglobin, the photoactive yellow protein (PYP) and bacteriorhodopsin.The instrumentational work led to an improvement of the time resolution for pulsed Laue experiments from 10 ns to 100 ps.

Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3789, VI, 143 p. ()
The adhesion of wear resistant coatings with predominant covalent bond content is limited byhigh stresses of the layers and by the weak chemial interaction between the metallic substrateand the covalent top layer. One essential aim of this work was the investigation of the structure and properties of a-C:H layers on several interlayer materials (Al, Ti, Cr,Cu). [...]
