Quantitative analysis of protein-protein interactions governing TASK-1/TASK-3 intracellular transport
(2016-07-27)The transport of the K+-channels TASK-1 and TASK-3 to the cell surface is regulated by protein-protein interactions with either the COPI vesicle coat, or members of the phosphoadaptor protein family 14-3-3. Interactions ... -
Quantitive Photoemission Spectroscopy of Hydrogen Bonded Systems
(2011-02-08)Water, the most crucial substance on our planet, is characterized by its hydrogen bond network. Although numerous investigations have been carried out to study the nature of the hydrogen ... -
Quantum-state specific scattering of molecules from surfaces
(2014-10-15)In my work, I investigated the quantum-state resolved scattering of three different diatomic molecules (NO, CO, N2) from different surfaces, including Au(111) and Pt(111). I focused on measurements of the energy ... -
Radical Polymerization Kinetics in Systems with Transfer Reactions Studied by Pulsed-Laser-Polymerization and Online EPR-Detection
(2011-11-22)The SP-PLP-EPR technique has been developed for very detailed kinetic investigations into radical polymerization. The method which combines single-pulse-pulsed-laser-polymerization (SP-PLP) ... -
Radical Polymerization Kinetics of Non-Ionized and Fully-Ionized Monomers Studied by Pulsed-Laser EPR
(2016-06-29)The radical polymerization kinetics of non-ionized and fully-ionized monomers in organic and aqueous solution was investigated by SP–PLP–EPR, i.e., highly time-resolved single-pulse–pulsed-laser–polymerization (SP–PLP) in ... -
RAFT-Polymerisation an Oberflächen
(2007-07-24)Heterogeneous Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerizations using solid-supported dithiobenzoates, trithiocarbonate, and xanthates, respectively, using nanometer-sized ... -
Raman-Spektroskopie kleiner Moleküle und Molekülaggregate im Überschallstrahl nach thermischer Anregung
(2015-07-06)Small molecules and clusters have been characterized by spontaneous Raman scattering in a supersonic expansion. It is shown how vibrational and rotational temperatures in the jet can be determined using the Stokes/anti-Stokes ... -
Ramanspektroskopische Untersuchung der Esterfaltung in Überschallexpansionen, Oder: Wie man bei der Suche nach der Haarnadel im Esterhaufen fünf auf einmal findet
(2022-06-29)The conformational preference of linear alkyl chains with an ester group in the center was investigated using Raman spectroscopy in supersonic expansions. Like alkanes, short esters prefer a stretched conformation, but ... -
Reactivity at surfaces with high-dimensional neural network potentials
(2023-07-24)The surface of a material is critical for its properties, especially in heterogeneous catalysis. Surfaces properties can be probed, for example, by H atom scattering. However ab-inito theoretical investigations of H atom ... -
Reaktionen des Amino-di-<i>tert</i>-butylsilanols
(2003-11-26)In contrast to carbon chemistry in silicon chemistry a kinetic stabilization of compounds with two or three OH or NH2 groups bonded to one silicon atom is possible. The reaction of (Me3C)2Si(OH)Cl with liquid ammonia affords ... -
Reaktionen des Bis(tert-butyl-methyl)ketazins mit Halogensilanen
(2004-10-22)This thesis refers to the synthesis of unknown acyclic und cyclic silylketazines. Reactions of monolithiated bis(tert-butyl-methyl)ketazine with chloro- and fluorosilanes lead to acyclic ... -
