Gold nanorod surface functionalization: construction of dynamic surfaces and heterogeneous silica coating
… controlling the position of molecules on GNR surfaces is a major challenge in the field. The first aim of this thesis is to build up dynamic surface coatings on GNRs that change their thickness and reversibly responsible to specific outside stimuli. Poly (N-isopropylacrylamide) (PNIPAM), with …

DYNAMIC SURFACES FOR URINARY CATHETERS: THE EFFECT OF POLY (GLYCEROL SEBACATE CITRATE) COMPOSITION ON DEGRADATION, ENCRUSTATION RESISTANCE AND BACTERIAL RESPONSE
Encrustation and blockage of urinary catheters, caused by the formation of crystalline biofilms, has been a problem since their invention more than 90 years ago. This thesis addresses the issue via a biomaterials approach, specifically, utilising poly glycerol sebacate citrate (PGSC) produced …

Six degrees of freedom estimation using monocular vision and moiré patterns
… hovering, static platform landings, and dynamic platform landings to display the algorithm's ability to provide accurate information to precisely control the vehicle. The results confirm the moire target system's feasibility as a viable option for low-cost relative navigation for indoor …

Design and manufacturing of PDMS micro structures with dynamic inclination angle
… textures. This work focuses on designing new dynamic surfaces that can change their micro and nanoscale texture due to in-plane mechanical strain. The studied textured surfaces have vertical 1D nanostructures, such as carbon nanotubes, integrated on flexible carrier films with inclined …

Introducing mobile robots on the automotive final assembly line : control, sensing and human-robot interaction
… lines present a distinct challenge in form of surfaces that are dynamic, i.e., the conveyor belts which ferry cars in the factory. I develop a control strategy to enable autonomous navigation on such dynamic surfaces, and design a sensing module capable of detecting the conveyor belts. The …

Sketching as a support mechanism for the design and development of shape-changing interfaces
… which incorporate physical, tangible, and dynamic surfaces to create a true 3-Dimensional experience. As is often the case with other novel hardware, the current research focus is on iterative hardware design, with devices taking many years to reach potential markets. Whilst the drive to …

Image-based Fine-scale Infrastructure Monitoring
… and is capable of reconstructing objects or surfaces with homogeneous texture. The scientific contributions of this research work address the drawbacks in currently existing literature. Methods for in-situ multi-camera system calibration and system stability analysis are proposed in addition …

Dynamic-template-directed crystallization of semiconducting polymers for organic electronics
… more favorable than that of the bulk. Dynamic surfaces play a critical role in templating highly ordered complex structures in living systems (e.g., biomineralization). This strategy is rarely employed for directing assembly of the synthetic functional materials. In my thesis, I …

The prediction of bubble defects in castings
… Acceptor method is of use when modelling highly dynamic surfaces, such as those encountered during the metal pouring phase in castings, or when fuel sloshes in a fuel tank. This method is best for capturing the entrapment of large bubbles of gas by surface folding. A process directly related to …
