Influence of hydrophobically modified polyelectrolytes on nanoparticle synthesis in self-organized systems and in water
… of metal colloids in aqueous solution by adding self-synthesized hydrophobically modified polyelectrolytes were studied in much more details. The polymers used are hydrophobically modified derivatives of poly(sodium acrylate) and of maleamic acid copolymers as well as the commercially available …

Quantum-size effects in the electronic structure of novel self-organized systems with reduced dimensionality
The Thesis is focused on the properties of self-organized nanostructures. Atomic and electronic properties of different systems have been investigated using methods of electron diffraction, scanning tunneling microscopy and photoelectron spectroscopy. Implementation of the STM technique (including …

Informal Car Share's Contribution to Urban Resilience in Quito, Ecuador
… routes and fares. This is similar to formal systems operated by the government. Users and drivers described ICS as reliable and consistent, and they all reported a positive experience with the service. Findings also suggested that Quito's ICS is disrupted by six natural and political …

The political economy of policing in Zimbabwe: Changing roles, practice and identities in relationship to peace, security and development
… from the government they recalibrate into self-organized systems and devise ways in which they raise the much needed revenue for policing. Using interpretive content analysis for secondary data and thematic analysis for in-depth interviews, the other finding relates to the ways in which the …

Self-organization in Models of Cyclically Sheared Suspensions
<p>This thesis presents a study of random self-organized systems using computer-simulated models inspired by cyclically-sheared non-Brownian suspensions of monodisperse spherical particles in a density-matched fluid. When driven at low Reynolds number, such systems have vanishing thermal …

Interfaces between Competing Patterns in Reaction-diffusion Systems with Nonlocal Coupling
In this thesis we investigate the formation of patterns in a simple activator-inhibitor model supplemented with an inhibitory nonlocal coupling term. This model exhibits a wave instability for slow inhibitor diffusion, while, for fast inhibitor diffusion, a Turing instability is found. For moderate …
