Complementary to scattering techniques, scanning tunnelling microscopy provides atomic-scale real space information about a material's electronic state of matter. State-of-the-art designs of a scanning tunnelling microscope (STM) allow measurements at millikelvin temperatures with unprecedented energy resolution. Therefore, this instrument excels in probing the superconducting state at low temperatures and especially its local quasiparticle excitations as well as bosonic degrees of freedom.

In this work, a clear pathway is presented to achieve well-defined electronically decoupled chromophores from metallic leads without requiring additional insulating layers. To study such self-decoupled molecules, STM equipped with an efficient light detection setup has been used. Results show that the chromophores mounted on tripodal molecular platforms adsorbed on a gold surface present well-defined and efficient electroluminescence down to the single-molecule level.

Präzise Warnungen vor den Begleiterscheinungen von Gewittern sind für Präventionsmaßnahmen unerlässlich. Die dynamische Entwicklung von Gewitterzellen führt oft zu einer großen Diskrepanz zwischen den Echtzeit-Vorhersagen der Wetterdienste und den beobachteten Wetterbedingungen. Daten eines Zellverfolgungsalgorithmus werden mit Modellanalysen kombiniert, um den Lebenszyklus von Gewittern in Deutschland zu analysieren und Verfahren für die Echtzeit-Vorhersage zu entwickeln und zu evaluieren.
Precise warnings of the accompanying effects of thunderstorms are essential for preventive measures. The dynamic development of thunderstorm cells often leads to a large discrepancy between the real-time forecasts (nowcasts) of weather services and the observed weather conditions. Data from a cell tracking algorithm are combined with model analyses to investigate the life cycle of thunderstorms in Germany and to develop and evaluate procedures useful for thunderstorm nowcasting.

Die Hochtemperatur-Brennstoffzelle (SOFC) als Strom- und Wärmeproduzent der Zukunft stellt eine wichtige Schlüsseltechnologie für eine klimafreundliche Energieversorgung dar. Vorrangige Entwicklungsziele sind die Verbesserung der Lebensdauer und die Verringerung der Kosten der SOFC-Komponenten. In dieser Arbeit werden mikrostrukturelle Veränderungen, die während der Zellherstellung und im Betrieb (Alterungsverlauf) auftreten, durch den Einsatz mehrskaliger Untersuchungsmethoden identifiziert.
The solid oxide fuel cell (SOFC) as electricity and heat producer of the future represents a key technology in the context of a climate-friendly energy supply. Research focuses on the improvement of the lifetime and cost reduction of the SOFC components. In this work, microstructural changes that occur during cell production and operation (aging process) are identified by multiscale examination methods.

The impact of land-surface properties like vegetation, soil type, soil moisture, and the orography on the atmosphere is manifold. These features determine the evolution of the atmospheric boundary layer, convective conditions, cloud evolution and precipitation. The impact of model grid spacing and land-surface resolution on convective precipitation over heterogeneous surfaces is investigated using ICOsahedral Nonhydrostatic (ICON) simulations within the framework of the HD(CP)2 project.

Quantum sensing is a vast and emerging field enabling in-situ studies of quantum systems and hence the development of quantum hybrid systems. This work creates the fundament of direct superconducting-magnetic hybrid systems by developing a local microwave sensing scheme and studying the influence of a static magnetic field on a superconducting qubit. Finally, a proof-of-principle hybrid system is demonstrated, which opens the path towards superconducting-magnetic quantum circuits.

The trend towards larger power ratings of wind turbines asks for innovations in power generation, which requires lower weight and cost, smaller size, higher efficiency and reliability. Due to high current-carrying capability and no DC losses of superconductors, a superconducting wind generator can have a superior power to weight/volume ratio with high efficiency. The work in the book mainly focuses on the feasibility study and design of a superconducting DC wind generator.
