Surfaces
Surfaces is a collection of four individual essays which focus on the characteristics and tactile qualities of surfaces within a variety of perceived landscapes. Each essay concentrates on a unique surface theme and purpose; each essay offers observations and speculations with regard to surface …

Saddle Surfaces
… surface and we prove that the space of saddle surfaces in an reals0 domain is complete in the Frechet distance. We also prove a compactness theorem for saddle surfaces in realskappa domains; in spaces of constant curvature we obtain a stronger result based on an isoperimetric inequality for a …

Programmable surfaces
… character of momentum transport across their surfaces. These existing approaches rely on bulk response among the fluids and solids. They are often not finely controllable and complex approaches suffer from manufacturing and practical operational challenges. In contrast I present a study of a …

Liquid repellent surfaces
… important role in repellency. Liquid repellent surfaces have been produced by the pulsed plasma polymerisation of I H, 1 H,2H,2H -heptadecafluorodecyl acrylate. These films have chemical functionalities indicative of polymerisation occurring through the acrylate double bond, as shown by Infrared …

Switchable biological surfaces
The ability to control properties such as wettability and bio-molecule immobilisation onto self-assembled monolayers (SAMs) has many potential biological and medical applications. The aim of this project was to produce mixed biotinylated peptide monolayers that are responsive to an electric …

Curves on surfaces
… geometric and combinatoric problems of curves on surfaces. In Chapter 3, we show that certain families of iso-length spectral hyperbolic surfaces obtained via the Sunada construction are not generally simple iso-length spectral. In Chapter 4, We prove a strong form of finite rigidity for pants …

Thread-wire surfaces
This thesis studies surfaces which minimize area, subject to a fixed boundary and to a free boundary with length constraint. Based on physical experiments, I make two conjectures. First, I conjecture that minimizers supported on generic wires have finitely many surface components. I approach this …

Adaptable structural surfaces
The framework for this thesis are the lightweight constructions that have been developed during the 20th century. As part of this thesis, a prototype for a column has been developed, that is a hybrid construction out of a lattice and surface structure. It follows the principle of adaptability …

Hydrate-phobic surfaces
… involves reducing the adhesion of hydrates to surfaces, ideally to a low enough level that the force of flow detaches them and prevents plug formation. Systematic and quantitative studies of hydrate adhesion on smooth surfaces with varying energies were conducted. Surface energies were …

In Situ Studies of Promoted Catalytic Surfaces and Redox Active Mineral Surfaces
… to probe reaction chemistry on two sets of surfaces; the first, a silicon-copper alloy surface where copper acts as a catalyst in the synthesis of methylchlorosilanes, and the second, a redox active iron-sulfur surface. Spectroscopic information obtained in situ will be combined with kinetic …

Maximal Surfaces in Complexes
… is defined to be the maximum genus of all surfaces that are subcomplexes of the cubical complex. A formula is given for determining the genus of the cubical complex C(k_1,...,k_n) when at least three of the k_i are odd integers. For the remaining cases a general solution is not known. When …

Cells, surfaces and adhesion
This thesis concerns cell adhesion to polymer surfaces with an experimental emphasis on hydrogels. The thesis begins with a review of the literature and a synthesis of recent evidence to describe the process of cell adhesion in a given situation. The importance of understanding integrin-adhesion …
