Anwendungsbezogene Weiterentwicklung der abbildenden Ellipsometrie

Röling, Christian (2017-10-10)

Since the work of Geim of graphene as the first 2D material, application and rese- arch of 2D materials is the main booming branch this decade. Overall the imaging techniques like RAMAN Imaging, AFM and optical microscopy ...

Biomimetic Polymer Systems via RAFT Polymerization - Routes to High-Performance Materials

Hendrich, Michael (2016-12-13)

Nature provides numerous examples of structural materials with outstanding mechanical properties. An especially intriguing material is spider dragline silk that outmatches man-made high-performance fibers such as Kevlar ...

Diagonal and Off-Diagonal Anharmonicity in Hydrogen-Bonded Systems

Heger, Matthias (2016-05-11)

The stretching wavenumber of a functional group exhibits a characteristic shift towards lower energies when serving as a hydrogen bond donor. This well-known effect constitutes an important tool for the study of such ...

Electron Emission from Metastable Carbon Monoxide Molecules at Adsorbate Covered Au(111) Surfaces

Engelhart, Daniel Paul (2015-07-09)

Understanding the fundamentals of energy transfer between molecules and surfaces is of profound importance in modern chemistry. Here, I investigate an important energy transfer process, electron ...

Funktionelle Polymere mittels kontrollierter Polymerisationstechniken: Von der Massenspektrometrie endfunktionalisierter Polymere und den mechanischen Eigenschaften photovernetzbarer Blockcopolymere

Staudt, Byron Helmut (2019-02-06)

In this thesis polymers were functionalized with terminal ammonium groups leading to new fields of their application. Their analysis by mass spectrometry was optimized or became generally accessible. In addition, reversibly ...

Generation of H-Atom Pulses and Associative Desorption of Hydrogen Isotopologues from Metal Surfaces

Kaufmann, Sven (2018-03-28)

Part I of this work introduces a technique for the generation of H-atom pulses with unprecedented time resolution. In part II an extensive study of the associative desorption reaction of hydrogen isotopologues from metal ...

Größenselektive Untersuchungen zur Kristallisation und Struktur von Wasserclustern

Pradzynski, Christoph Czeslaw (2015-05-19)

Vibrational spectra of neutral Na(H2O)n clusters in the OH stretching region (2800 – 3800 cm-1) were measured size selectively up to n=575±25. The IR action spectra were obtained by exploiting the increase to the photoionization ...

Kinetik der radikalischen Polymerisation von Monomeren mit mesogener Seitengruppe in isotroper und anisotroper Lösung

Groschopp, Alex (2018-03-19)

This work targets the radical polymerization of reactive mesogens in isotropic and anisotropic solution. Kinetic coefficients were determined via pulse-laser polymerization in conjunction with size-exclusion chromatography ...

Orientation-dependent energy transfer in gas-surface collisions: Scattering of vibrationally excited nitric oxide from Au(111)

Bartels, Nils (2015-07-14)

The work in my thesis is a contribution to the field of chemical dynamics at surfaces. In this field we seek to develop a detailed microscopic understanding of chemical events taking place on surfaces. Progress in ...
