Towards an active matter perspective on sarcomere dynamics in cardiomyocytes
(2023-04-19)The contraction of cardiac muscles emerges from the collective dynamics of myosin motor proteins organized in sarcomeres, 2 μm-sized contractile units. Inside individual cardiomyocytes, dozens of sarcomeres in series form ... -
Carbon Nanotubes as Fluorescent Probes in Living Drosophila Embryos
(2020-02-13)In this project, a promising imaging method using NIR fluorescent, DNA-wrapped CNTs is applied to study their optical and dynamical behavior in syncytial Drosophila embryos. Drosophila (commonly known as vinegar fly) is ... -
Ultraschallunterstützte Kupferabscheidung
(2017-08-03)The electroless and electrolytic copper deposition are essential process steps in the production of printed circuit boards. Various studies have already shown that ultrasound can improve these processes. However, ultrasound ... -
Temperatureffekte bei der lasererzeugten Kavitation
(2017-04-03)The purpose of this thesis is to examine how the dynamics of single laser-generated bubbles is affected by the water temperature. In addition, the heat transport between a bubble and the surrounding liquid throughout ... -
Liquid Crystal Microswimmers - from single entities to collective dynamics
(2016-11-15)Recently, artificial self-propelled systems at low Reynolds numbers have gained a lot of attention. The main interest lies in mimicking well-studied systems, e.g. the active Brownian motion of bacteria, or in gaining deeper ... -
On the mechanics of biopolymer networks
(2016-06-07)In this thesis, we study the mechanical properties of biopolymer networks. We discuss which of these properties can be described by continuum approaches and which features, on the contrary, require consideration of the ... -
DNA-based molecular force sensors in cytoskeletal networks and cells
(2015-07-30)Eukaryotic cells are highly active and undergo force generating processes such as cell adhesion, migration and division. The cytoskeleton, a polymer meshwork in cells, plays an important role in these cellular processes. ... -
Erzeugung und Untersuchung von schnellen Mikrotropfen für Reinigungsanwendungen
(2015-06-16)For more than a century, there exists a growing scientific interest in drops and the mechanisms involved during their impact onto various surfaces, probably initiated by the photographic recordings by Worthington (1908). ... -
Label-Free Measurements of Amyloid Formation by Suspended Microchannel Resonators
(2014-12-12)Amyloid deposition in tissues is a hallmark of many severe diseases including Alzheimer’s and Parkinson’s disease. The formation of amyloid fibrils involves several intermediate steps, and revealing the kinetics of each ... -
Untersuchung von akustischen Strömungen im kHz- und GHz-Bereich
(2014-07-14)Launching ultrasound into a fluid can lead to a steady streaming due to nonlinearity and damping. These streaming which is caused by a momentum transfer from the soundwave to the liquid is called acoustic streaming. This ... -
Structures and Self-Organization at Liquid Crystal Interfaces: Surface Ordering and Anchoring
(2013-04-22)This dissertation concerns research on the structures and self-organization at liquid crystal interfaces laden with surface-active molecules. Of particular interest are the surface ordering phenomena occurring at interfaces ... -
Single-molecule experiments with mitotic motor proteins
(2012-10-24)This cumulative PhD thesis covers in five chapters (chapters 2, 3, 4 and 5 consisting of published papers and chapter 6 consisting of a submitted manuscript) new findings on different aspects of the regulation of kinesin-5 ... -
Towards autonomous soft matter systems: Experiments on membranes and active emulsions
(2011-09-02)This thesis presents experiments on lipid bilayer membranes and non-equilibrium phenomena in active emulsion droplets. In the first part, we outline a concept of self assembled soft matter ... -
Charakterisierung von Kavitationsblasenpopulationen
(2011-06-22)Acoustic cavitation denotes the nucleation and dynamics of bubbles in liquids under insonication. It is found that bubbles in an acoustic cavitation field do not form a homogeneous group, ... -
Sensitivity Enhancement of Liquid-State NMR and Improvement of the INPHARMA Method
(2011-03-07)In the presented work the possibility of signal enhancement of high-resolution nuclear-magnetic-resonance (NMR) in aqueous solution, with the intent of application to macromolecular ... -
AFM Untersuchungen an smektischen Flüssigkristallen
(2009-08-12)This thesis presents an experimental study of focal conic domains in smectic liquid crystal films on solid substrates. Focal conic domains are complex structures in smectic phases and are ... -
Structure of charged two-component lipid membranes and their interaction with colloids studied by different X-ray and microscopy techniques
(2009-03-30)The aim of this thesis is to improve our understanding of the structure of charged two-component lipid membranes and to give insights into the mechanisms behind colloid-membrane interactions.The ... -
Critical Behavior and Crossover Effects in the Properties of Binary and Ternary Mixtures and Verification of the Dynamic Scaling Conception
(2008-03-18)Ultrasonic attenuation spectra in the frequency range between 180 kHz and 500 MHz, dynamic light scattering and shear viscosity measurements of a variety of liquids exhibiting a demixing point have been measured are ... -
Manipulation of Wetting Morphologies in Topographically Structured Substrates
(2008-02-11)In the present work, static liquid morphologies confined to linear micron sized surface grooves were studied experimentally and analyzed theoretically. Geometries with increasing complexities, ...
