Mechanical and biochemical stimulation of suspended cells in a microfluidic device probed with dual optical tweezers
(2018-01-30)Cells communicate with their environment through biochemical and mechanical interactions. They can respond to stimuli by undergoing shape- and, in some situations, volume changes. Key determinants of the mechanical response ... -
Mechanosensing and Symmetry of Potassium Channels Studied by Molecular Dynamics Simulations
(2018-10-02)Potassium channels are relevant in a variety of physiological processes in all three kingdoms of life. In mammals these processes including nerve signaling, heartbeat regulation, and osmotic regulation of cells. Thus a ... -
Minimal models for lipid membranes: local modifications around fusion objects
(2013-02-01)Solvent-free soft coarse-grained models are particularly appropriate to investigate collective phenomena in lipid membranes. In this work we exploit such a model to show how modifying a few model parameters we can control ... -
Molecular Dynamics simulations of polymer liquids on substrates of different topography
(2013-02-04)The properties of polymer films and droplets at substrates of different topography are studied employing particle-based simulation techniques (Molecular Dynamics). The liquid is modeled by short coarse-grained polymer ... -
Morphological instabilities in drying colloids
(2018-10-15)The crystallization of hard sphere colloidal dispersions show a variation of phase behaviours, as the volume fraction of colloidal dispersions increases, particles transform from a liquid to a crystal state, which two ... -
Multiscale simulations of liquid-liquid interfaces: From lipid membrane to graphene
(2023-11-06)There is an increasing demand to enhance the development of coarse-grained models in order to facilitate highly efficient simulations of realistic biological systems. In our endeavor to tackle this challenge, in chapter ... -
Random Block Copolymer Melts in the Bulk and at Selective Substrates
(2011-12-15)Random block copolymers are polymers that consist of two different, randomly as- sembled types of blocks. Each of these blocks comprises one type of monomer and a repulsion between these ... -
Refining the chemical and kinetic decoupling description of thermally produced dark matter
(2019-03-26)The first part of this thesis deals with refined theoretical predictions of the thermal relic abundance for weakly interacting massive particles (WIMPs). Methods are developed in a model independent way to describe the ... -
Rheology and Structure Formation in Complex Polymer Melts
(2019-04-17)Polymeric materials are ubiquitous in our modern lives. Their many applications in complex materials are accompanied by potentially huge benefits for technological advancement. These applications range from batteries, ... -
Statics and dynamics of solvent-free models for liquid bilayer membranes
(2011-05-31)Collective phenomena in lipid membranes, like pore formation and fusion, self-assembly, or lateral demixing of lipid mixtures, have attracted tremendous interest over the last years. Often, ... -
Stochastic field theory of viscoelastic solids: a quantitative study of phononic friction
(2022-07-27)Identifying the relevant dynamics of solids that give rise to friction is an active field of study. It includes electronic and phononic degrees of freedom, but the latter seems to be of particular significance. For instance, ... -
Structure Determination From Single Molecule X-Ray Scattering Experiments using Photon Correlations
(2018-06-18)Scattering experiments with femtosecond high-intensity free-electron laser pulses provide a new route to macromolecular structure determination without the need for crystallization at low material usage. In these ... -
Structure Formation and Collective Behavior of Dipolar Active Particles
(2021-12-13)Dipolar active particles describe a class of self-propelled, biological or artificial particles. These particles are equipped with an internal, typically magnetic, dipole moment. The combination of dipolar particle-particle ... -
Structure formation in binary polymer systems: Short-time dynamics and dynamics of crosslinked systems
