Time-Resolved Spectroscopy of Transition Metal Complexes
(2024-01-23)
Owing to their thermodynamic properties, transition metal azido compounds are often prone to decomposition. Frequently, this occurs under release of dinitrogen giving rise to nitrene or nitride complexes which are of ...
The Development of Chiral Titanocenes as Photoredox Catalysts
(2023-01-24)
This dissertation describes the advances in photochemically activated (chiral) titanocenes as both electron transfer and photoredox catalysts in epoxide opening reactions. Based on the discovery of the photoredox-active ...

Katalytische Reaktionen auf VO2-Polymorph Oberflächen unter Ausnutzung des Phasenübergangs
(2024-01-17)
Aufgrund des wachsenden Energiebedarfs der Menschheit werden energieeffizientere und neuartige Verfahren zur Herstellung von chemischen Grundstoffen mithilfe von Katalyse gesucht. Fluktuierende Reaktionsbedingungen werden ...
Functional characterization of Gαi/s proteins and modulation of their activity by linear and cyclic peptides
(2024-01-30)
Heterotrimeric Gαβγ (guanine nucleotide-binding) proteins serve as molecular switches to activate (“switch on”) or inactivate (“switch off”) diverse intracellular signaling cascades in response to stimulated G protein-coupled ...
Zintl Anions, Polychalcogenides and Chalcogenometalates via Solvothermal Syntheses
(2024-02-29)
The focus of this work is on the synthesis and structural investigation of polychalcogenides and Zintl phases. Therefore, mainly ammonothermal syntheses under mild or supercritical conditions were used. Additionally, some ......
Control of pulmonary immunity by physical exercise
(2024-03-06)
Sedentary lifestyles combined with high caloric nutrition are widely known to severely contribute to the rise of metabolic diseases like diabetes, atherosclerosis, or obesity in recent years. While endurance training has ......
Synthese und Charakterisierung neuer Thiophosphate mit Chrom und Vanadium
(2024-03-07)
Es konnten zehn neue Thiophosphatverbindungen synthetisiert und ihre Kristallstrukturen aufgeklärt werden. Zusätzlich konnten zwei Verbindungen mit bisher ungeklärter Kristallstruktur synthetisiert werden.
