Water Soluble Photochromic Fluorescent Nanoprobes based on Diheteroarylethenes and Polymer Coated Quantum Dots
(2013-12-20)The rapidly growing field of fluorescence microscopy is dependent on the introduction of new, versatile probes. Quantum dots (QDs) are of great interest due to their brightness, fatigue resistance, large extinction ... -
Weak Hydrogen Bonds to Molecular Nitrogen and Oxygen as Experimental Benchmarks for Quantum Chemistry
(2019-03-22)Small molecular complexes in the gas phase weakly bound by hydrogen bonds to molecular nitrogen and oxygen are studied by vibrational and rotational spectroscopy. The obtained experimental data are used as benchmarks for ... -
Weiterentwicklung diffusionsspektroskopischer NMR-Methoden für metallorganische Schlüsselverbindungen
(2023-10-02)This work has extended the development and application of NMR diffusion spectroscopic techniques for the determination of the molecular weight of compounds in solution. In the process, methylcyclohexane-d14 was added to ... -
Wetting heterogeneities in porous media
(2014-04-28)Multiphase flow in porous media is an important process for many technical and environmental applications such as fuel cells, oil recovery, CO2 storage among others. Understanding the rules that govern these flows is ... -
Zeitaufgelöste Fluoreszenzspektroskopie unimolekularer Reaktionen im Überschalldüsenstrahl: <i>trans-cis</i>-Photoisomerisierung, Phenylringtorsion, intramolekularer Wasserstoffatomtransfer
(2005-11-02)In this work three types of unimolecular reactions were studied spectroscopically and theoretically with model systems: (1) the trans-cis-photoisomerization of trans-stilbene and its ... -
Zeitaufgelöste inelastische Neutronenstreuung an entmischenden Silber-Natriumchlorid-Einkristallen
(2002-11-20)The kinetic of decomposition in silver sodium chloride single crystals has been studied by means of the evolution of phonon spectra. In the early stages of decomposition a spinodal ... -
