Kinetics of free radical homo- and copolymerisations investigated with pulsed laser methods
(2024-03-06)Free-radical polymerisation is the most important polymerisation process due to its simplicity and robustness. It is therefore necessary to understand the kinetics of the involved reactions in order to plan a polymerisation, ... -
Application of Laser Induced Desorption to study Velocity-Resolved Kinetics
(2023-05-04)In this work, I present a new method to measure velocity-resolved kinetics (VRK) of chemical reactions on surfaces. Ultra-fast laser-induced desorption (LID) is utilized as a tool to directly measure coverages of adsorbates. ... -
Aggregations- und Evaporationsdynamik von Clustern und Aerosolpartikeln im H<sub>2</sub>SO<sub>4</sub>-H<sub>2</sub>O-System
(2022-11-28)Sulfuric acid and water are two key compounds in the formation of atmospheric aerosols and are therefore relevant in the context of climate research. In this work, a modified experimental setup is presented, using the ... -
IR-anregungsmodulierte Photoionisationsspektroskopie an natriumdotierten Wasserclustern
(2021-10-19)The compound water exhibits a variety of unique properties which are indispensable for many processes in animate and inanimate nature. These properties do not arise from a single water molecules but from the strong anisotropic ... -
Termination Kinetics of Radical Homo- and Copolymerizations Studied via Time-Resolved EPR Spectroscopy
(2021-06-01)This thesis provides an in-depth investigation into the chain-length dependent termination kinetics of radical homo- and copolymerization by using the most powerful method: single pulse–pulsed laser polymerization (SP–PLP) ... -
Charakterisierung maßgeschneiderter makromolekularer Systeme: Analyse von photoschaltbaren Polymeren und Untersuchung der Wärmeleitfähigkeit von Polymeren und Polymernanokompositen
(2021-04-23)In this work, tailored azobenzene-based polymers were synthesized and characterized with respect to their isomerization kinetics, micro structure and thermal conductivity. Additionally, the thermal conductivity of ... -
Ion mobility mass spectrometry as a powerful tool to analyze complex macromolecular systems
(2021-02-01)Modern applications of polymers rely on intricately tailored macromolecules exhibiting very specific properties and therefore require extensive analysis. In this context, IMMS is an immensely powerful technique since it ... -
Tailoring the Mechanical Properties of Montmorillonite-Nanocomposites via Surface-Bound RAFT-Polymer
(2021-01-19)The successful preparation of Montmorillonite--polymer-nanocomposites with tailorable mechanical properties via surface grafting of RAFT polymers was presented. Strategies to precisely tune the properties of filler--matrix ... -
Klassifizierung polarer Metall-Kohlenstoff-Bindungen in hauptgruppenmetallorganischen Verbindungen mittels experimenteller Elektronendichteanalyse
(2020-10-20)In general, organometallic compounds are characterized by their metal-carbon bond. This is characterized by its polar nature. Examples of this class of compounds are Grignard reagents and organolithium compounds such as ... -
Investigation of Polymer-Filler Interactions Using Functionalized Nanoparticles
(2020-03-16)Silica and carbon black (CB) particles were successfully functionalized by exploiting the characteristic features of the reversible addition--fragmentation chain transfer (RAFT) polymerization. This enabled both the ... -
Theoretical high-resolution spectroscopy for reactive molecules in astrochemistry and combustion processes
(2019-12-19)Rovibrational spectroscopy is a prime tool for the indirect investigation of molecular potential energy surfaces (PES). Naturally, theoretical predictions of molecular spectra have been the focus of numerous works since ...
