Superconducting digital electronics based on rapid single flux quantum (RSFQ) logic is one of the most promising applications of the Josephson effect. The mainadvantages of RSFQ circuits are ultra high speed and extremely low power dissipation [...]

Solar neutrinos have played a central role in the discovery of the neutrino oscillation mechanism. They still are proving to be a unique tool to help investigate the fusion reactions that power stars and further probe basic neutrino properties [...]

The Jiangmen Neutrino Underground Observatory (JUNO) is a 20 kton liquid scintillator detector currently under construction near Kaiping in China. The physics program focuses on the determination of the neutrino mass hierarchy with reactor anti-neutrinos. [...]

Dynamik instabiler Oberflächen, dieser Themenbereich wurde in dieser Arbeit unter mehreren Gesichtspunkten und in verschiedenen Zusammenhängen behandelt. Den physikalischen Hintergrund bildet die Morphologie wachsender Kristalloberflächen [...]

The first simultaneous measurement of the interaction rates of pp, 7Be, and pep solar neutrinos has been completed using the Borexino data and will soon be published. The results were obtained by performing a global fit to the Borexino Phase-II data in an extended energy range (0.186-2.97 MeV). [...]

Basierend auf der Hochdruck-Magnetronsputtertechnik wurden geeignete Prozesse zur reproduzierbaren großflächigen Abscheidung von supraleitenden YBa$_{2}$Cu$_{3}$O$_{7- \delta}$- und isolierenden NdGaO$_{3}$- und CeO$_{2}$-Schichten entwickelt. Dazu war es notwendig wichtige Systemkomponenten (Kathodensystem und Substratheizer) zu modifizieren [...]

Titanium aluminide alloys based on Ti$_{3}$Al and TiAl are of particular interest for the development of light weight materials because oftheir low density. These alloys can be used for parts ofthe jet turbine as well as for the airframe [...]

$\textit{Corynebacterium glutamicum}$ wird seit vielen Jahren zur großtechnischen Gewinnung der Aminosäuren L-Glutamat und L-Lysin eingesetzt. Im Rahmen dieser Arbeit sollte untersucht werden, inwieweit die L-Isoleucinbildung mit Hilfe molekularbiologischer Methoden gesteigert werden kann und welcher Mechanismus die Expression der Gene der Acetohydroxysäuresynthase reguliert. [...]

Semiconductor spins are one of the few qubit realizations that remain a serious candidate for the implementation of large-scale quantum circuits. Excellent scalability is often argued for spin qubits defined by lithography and controlled via electrical signals, based on the success of conventional semiconductor integrated circuits. [...]
