Zeitaufgelöste Femtosekunden-Infrarotspektroskopie an einem Ferracyclobutadien zur Aufklärung des ultraschnellen photoinduzierten Ligandenaustauschs
(2017-04-19)
Diese Arbeit hat es sich zum Ziel gesetzt, die ultraschnellen Primärprozesse nach der optischen Anregung des Tricarbonyl-Ferracyclobutadien-Komplexes [Fe{κ2-C3(NEt2)3}(CO) ...
Measurement of Double Polarization Observables in the Reactions γp → pπ0 and γp → pη with the Crystal Barrel/TAPS Experiment at ELSA
(2017-10-10)
One of the remaining challenges within the standard model of particle physics is to gain a good understanding of QCD in the non-perturbative regime. A key step toward this aim is to obtain further insight into the structure ...
Studies of ω Photoproduction off Proton at the BGO-OD Experiment
(2017-09-21)
Hadrons are composite particles which experience a mutual, non-fundamental interaction, i.e. the same force responsible for keeping protons and neutrons bound together within the atomic nucleus. This hadronic interaction ...
Organization and function of signaling molecules in sperm
(2017-09-15)
Successful fertilization depends on the ability of sperm to locate the egg. Sperm from different species rely on diverse signaling components to gather chemical and physical cues and transduce them into a behavioral swimming ......
Um die Eizelle zu befruchten, müssen die Spermien die Eizelle zunächst lokalisieren. Dabei helfen ihnen unterschiedliche chemische oder physikalische Signale auf dem Weg zur Eizelle, die dann das Schwimmverhalten der ......

Development of a serial powering scheme and a versatile characterization system for the ATLAS pixel detector upgrade
(2017-08-22)
In order to increase the probability of new discoveries the LHC will be upgraded to the HL-LHC. The upgrade of the ATLAS detector is an essential part of this program. The entire ATLAS tracking system will be replaced by ...
Active Plasmonic and Dielectric Nanoantennas
(2017-08-10)
This thesis presents results on the fabrication, investigation and characterization of active optical nanoantennas. The three partial results in order of their occurrence are: (i) The demonstration of the operational ...
Testing the Quantumness of Atom Trajectories
(2017-05-15)
This thesis reports on a novel concept of state-dependent transport, which achieves an unprecedented control over the position of individual atoms in optical lattices. Utilizing this control I demonstrate an experimental ......
Performance evaluation of a fully depleted monolithic pixel detector chip in 150 nm CMOS technology
(2017-09-01)
The depleted monolithic active pixel sensor (DMAPS) is a new concept integrating full CMOS circuitry onto a (fully) depletable silicon substrate wafer. The realization of prototypes of the DMAPS concept relies on the ...
Magnetic Outflows in the Virgo Galaxy NGC 4388
(2017-07-21)
We investigate the effects of ram pressure on the ordered magnetic field of the edge-on Virgo galaxy NGC 4388 hosting a radio halo and strong nuclear outflows. New radio images in total and polarized intensity were obtained ...
Materialmodifikationen in Lithiumniobat- und Lithiumtantalat-Kristallen durch Ionenbestrahlung
(2017-05-22)
Die künstlich hergestellten Kristalle Lithiumniobat (LiNbO3) und das eng verwandte Lithiumtantalat (LiTaO3) sind bewährte Ausgangsmaterialien zur Herstellung aktiver und passiver Bauelemente, die Licht ...
