Energy dissipation and transport in polymeric switchable nanostructures via a new energy-conserving Monte-Carlo scheme
(2018-04-13)Polymers are materials that are widely used in industry. The advantages of polymers are their comparatively simple possibility of processing, e.g, injection moulding processes, 3D printers, and self-assembly. Polymers ... -
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 ... -
Three-dimensional nonequilibrium steady state of active particles: symmetry breaking and clustering
(2017-08-04)Motile creatures are ubiquitous in the natural world. Spanning a broad range of length scales, they all have in common the fact that they convert energy from internal or external resources into motion. In most natural ... -
Elasticity of basic structural element in anisotropic macromolecular networks
(2016-09-27)Semiflexible filaments are abundant in biological materials. From cells to the extracellular environment, these kind of filaments are found. They are important for many biological organizations and processes. The maintenance ... -
Computer simulation and analysis of self-assembled alkylthiol monolayers on the surface of liquid mercury
(2016-08-10)In this dissertation I investigate the structure and thermodynamics of alkylthiol (thiol) surfactants on the surface of liquid mercury (Hg) by means of the large-scale Molecular Dynamics (MD) techniques. Simulations ... -
The interplay between curvature and composition in binary mixture lipid bilayers
(2016-04-08)In this work we investigate, via computer simulations with an implicit-solvent coarse-grained model, the interplay between curvature and composition in self- assembled lipid structures comprised by two lipid species with ... -
Continuously driven phase separation: size distributions and time scales in droplet growth
(2015-09-09)Phase separation arises in mixtures when temperature, pressure or concentrations of the mixture is changed such that a new macroscopic phase emerges. Typically the domains of the new phase take the form of droplets, bubbles ... -
Bayesian structure reconstruction from single molecule X-ray scattering data
(2015-02-11)X-ray free electron lasers (XFEL) offer new possibilities for molecular structure determination in single molecule experiments. In this thesis, I propose and assess two alternative Bayesian approaches, namely Orientational ... -
Liquid Crystals in Aqueous Ionic Surfactant Solutions: Interfacial Instabilities & Optical Applications
(2014-06-02)This thesis presents the properties and applications of various liquid crystal (LC)-aqueous ionic surfactant systems. It begins with the study of micellar solubilization of different LCs in aqueous ionic micellar solutions. ... -
Dynamics of soft interfaces in droplet-based microfluidics
(2014-04-30)This doctoral thesis presents the study of di erent dynamic processes occurring at the droplet interface, and the methods implemented for their study. The objective of this work is to unravel what are the important properties ... -
Contact Line Dynamics on Heterogeneous Substrates
(2014-04-14)Fluid interfaces in contact with solid substrates play an important role in fields ranging from microfluidics, over oil recovery and inkjet printing to coating processes. Effective models for the static wetting of structured ... -
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 ... -
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 ... -
Binary Mixtures and Fluids in the presence of Quenched Disorder
(2012-02-21)In the bulk, the critical point of a liquid-gas phase transition or a demxing transition of a binary mixture with short-ranged particle interactions belong to the universality class of the ... -
Understanding the molecular machinery of aquaporins through molecular dynamics simulations
(2012-01-02)Aquaporins are protein channels responsible for the permeation of water and other small solutes through biological membranes in response to osmotic pressure. The goal of the present thesis ... -
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 ... -
Elasticity and Morphology of Wet Fiber Networks
(2011-12-05)Fibrous materials are very commonplace in current technological applications. The study of their mechanics is an interesting topic that has previously been inspired by applications in the ... -
Statics and dynamics of solvent-free models for liquid bilayer membranes
