Die molekulare Bildgebung mit Hilfe der Positronen-Emissions-Tomographie (PET) ist wesentlich von derVerfügbarkeit geeigneter Radiotracer abhängig. Der erste Schritt im Entwicklungsprozess eines Radiotracers istdie Identifikation eines geeigneten molekularen Targets, welches durch den Radiotracer adressiert werden soll.Molekulare Targets sind beispielsweise Rezeptorproteine, die Erkrankungen aufzeigen können, da das regionaleRezeptorexpressionsprofil aufgrund pathologischer Prozesse verändert sein kann.

The High-Brilliance neutron Source (HBS) project aims at developing a low-energy accelerator-driven neutron source facility providing neutron beam brilliances at the corresponding instruments, which are very competitive to medium-flux fission-based research reactors. To obtain a large beam brilliance at HBS, the full-fledged facility simultaneously operates different neutron instruments, which subdivide into three target stations, each efficiently operated to supply different neutron pulse structures.

High-temperature co-electrolysis is the simultaneous electrochemical conversion of H2O and CO2 in the temperature range of about 700 – 900 °C. In this thesis solid oxide cells with ceramic electrolyte are used. [...]

One of the most challenging tasks in future nanoelectronics is the realization of novel low-power consumption devices for the application in non-volatile memories, processing, transduction and sensing units. Electric-field-control of the magnetism, which is based on the $\textit{magnetoelectric}$ (ME) effect, may pave the way towards an alternative concept to Si-based electronics relying on dissipative electrical currents.
