From individual to collective motion of self-propelled particles: The role of particle shape, orientational ordering and clustering
Diese Arbeit untersucht das Verhalten von aktiven getriebenen Teilchen, d. h. Teilchen, die sich unter Verbrauch von Energie gerichtet mit einer gegebenen Geschwindigkeit fortbewegen. Solche Teilchen sind per Definition fernab vom thermodynamischen Gleichgewicht und unterliegen daher nicht dem …

Homeostatic mechanics framework for modelling interactions of cells with the microenvironment
… adopted by cells in this period dictate orientational ordering, direction and speed of migration, lineage of differentiation and apoptosis. It is well established that cells display a fluctuating response in their microenvironments, and no two cells evolve in the same manner despite being …

Proton-coupled carbon-13 sample spinning NMR studies of macromolecules and ordered systems
… liquid-crystal displaying macroscopic orientational ordering behavior, by Carbon-13 ($\sp{13}$C) nuclear magnetic resonance (NMR) spectroscopy. We find that under ""magic angle"" spinning (MAS) these systems display high resolution due to extensive motions, and therefore traditional …

Experimental and computational analysis of random cylinder packings with applications
… structures were quantified by their positional ordering, orientational ordering, and the particle-particle contacts. Furthermore, the void space in the packings was expressed as a pore network, which retains topological and geometrical information. The significance of this approach is that any …

A quantum Monte Carlo study of the high-pressure phases of solid hydrogen
… to determining the equation of state and orientational ordering. We find that molecular hydrogen adopts a lower symmetry insulating structure over a wide range of pressure. The results of the atomic and molecular studies are combined to draw conclusions about the molecular-atomic …

Microscopic Physics of Electrical Double Layers
… and concentrated electrolytes, interfacial orientational ordering of common polar liquids such as water, and the effects of electrolyte confinement in pores down to the nanoscale. These effects are not captured in applications of standard continuum theories for dilute electrolyte solutions, …

Theoretical studies of lipid-protein interactions in biological membranes
… with increasing density. There is no long range orientational order within the lipids but the local orieritational order increases with increasing density. No first order phase transitions are observed though a glassy solid is observed at high densities. The properties of the bulk lipid are …

Molecular Structure, Diffusion Dynamics and Hydration Energetics of Non-Confined Water and Water at Mineral Surfaces
… structure and composition on the structural ordering, hydrogen bond organization, interfacial transport and hydration energetics of H2O molecules. Interaction between water and solid surfaces and changes in the structural and dynamical behavior resulting from local electric fields, geometric …

Phase Transitions and the Effect of External Fields in Thermotropic Main Chain Liquid Crystal Systems
… may be a reflection of the more facile uniaxial orientational ordering present in this system.

Hydrogen in thin film niobium
… of these Nb films show evidence for a novel ordering, long-range orientational ordering (LROO): For a portion of the film, the crystallographic planes are oriented over in-plane length scales larger than the in-plane atomic correlation length. The well-oriented planes are exactly parallel to …

Development of applications of liquid crystalline elastomers from Materials to Applications
… molecules called mesogens, exhibiting orientational ordering. These mesogens can self-assemble into many types of ordering and transition to being isotropic reversibly subjected to external stimuli. In the last four decades, this field has seen many advancements: the first generation of …
