Symplectic non-squeezing theorem and Hamiltonian partial differential equations
(2021-12-01)
The thesis is concerned with providing a first natural generalization of M. Gromov's non-squeezing symplectic result in infinite dimensional case and applying it within the context of Hamiltonian partial differential ...
Von neuen Li/Cl-Phosphinidenoid-Komplexen zuneuartigen funktionellen Phosphanyliden-Phosphoran-Komplexen
(2020-12-11)
Innerhalb dieser Arbeit wurden folgende drei unterschiedliche Fragestellungen der Komplexchemie behandelt: (1) Darstellung von Komplexen mit neuen dreigliedrigen heterocyclischen Liganden des N,P,E-Ringsystems (E = Bor, ...
Phenotyping of barley resistance to plant diseases on the leaf and greenhouse scale through hyperspectral imaging and data analysis
(2021-05-17)
Optical sensors become increasingly interesting as means to perform automated, non-invasive and objective monitoring in agriculture, but also have immense potential as tools for research and development. Especially ...
A role of Alzheimer’s disease-associated γ-secretase in lipid metabolism and lipid droplet formation via LXR activation
(2021-06-29)
The γ secretase is an intramembrane protease complex, essential for the processing of a wide variety of type-1 membrane proteins. Among these is the amyloid precursor protein (APP), a protein strongly linked to Alzheimer’s ...
Synthesis and reactions of Janus-type bis(NHCs), tuned by phosphorus bridges
(2021-02-15)
Due to our first attempts to synthesize P-functional bis(NHCs),[6] we were aware of a problem if bis(thiones) were used. Therefore, the idea emerged to use bis(selones) instead. Herein, the synthesis of the first tricyclic ...
Investigating 5-HT2A receptors - Development of a fluorescent 5HT2A receptor agonist and elucidation of the effects of St. John's wort extract STW3-IV, hyperforin and hyperoside on 5HT2A receptors
(2021-09-22)

Advanced Image Reconstruction Methods for Ultra-High Field MRI
(2020-07-07)
Magnetic resonance imaging (MRI) has become a very powerful and flexible medical imaging technique, that allows an unrivaled insight into human anatomy and physiology. For a wide range of possible applications, acquisition ...
The Influence of Solvent Reorganization on Organocatalytic Reactions
(2021-04-07)
In the last decades N-heterocyclic carbenes have shown a certain potential as organocatalysts. In addition to the formation of regio- and stereoselective C-C coupling reactions, their scope of application includes the ...
Applying Disaster Risk Governance in Dynamic Environments: Case study Rio de Janeiro State, Brazil
(2021-05-17)
Between 1980 and 2015, around 1.6 billion people were killed in meteorological, geophysical, hydrological or climatological disasters. Future annual losses are estimated to reach US4 billion in the built environment alone. ...
Characterization of the hyperpolarization-activated, highly-selective proton channel HCNL1 found in the sperm of the zebrafish Danio rerio
(2021-04-29)
Zebrafish are external fertilizers and release their gametes into the surrounding water. Yet, the freshwater environment with its low osmolarity poses a challenge for the gametes. Given these unique ion conditions, it seems ......
