This work focuses on experimental study of cross-property connections that link up effective linear elastic and electrical conductive properties of heterogeneous materials. Such connections are especially useful when one property (electrical conductivity) is easier to measure th…

Multi-pass fusion welding by a filler wire (welding electrode) is normally carried out to join thick steel sections used in most engineering applications. Welded joints in an installation, is the area of critical importance, since they are likely to contain a higher density of d…
Technological advances in device micro- and nano-fabrication over the past decade has enabled a variety of novel heterojunction device structures to be made. Among these, magnetic multilayers, superconductor/normal metal junctions and carbon nanotubes exhibit a rich variety of f…
Magnesium alloys, as the lightest of all structural metallic materials, and aluminium-based particulate metal matrix composites (PMMCs), offering unified combination of metallic and ceramic properties, have attracted increased interest from the automotive, aerospace, electronic …
This thesis describes the formation of and applications of self-assembled structures on metals. Primarily the focus of this PhD project is on the formation of surfaces structures on stainless steel (AISI 304) but other metals have been studied. Laser generated surface structures…
This thesis describes a number of studies of microstructured optical resonators, designed with the aim of enhancing the performance of organic semiconductor lasers and exploring potential applications. The methodology involves the micro-engineering of the photonic environment in…
In the TRISO (tristructural isotropic) coated fuel particle used in the High Temperature Reactor, the most important layer is a silicon carbide layer which acts as a pressure vessel. In this study, we have focused our study on the investigation of the Young’s modulus, hardness, …
We present a solution for one of the main limitations in classical interferometry and fringe projection, which is the dynamic range limitation. The technique is based on real time inverse fringe projection to enhance the dynamic range and increase the vertical resolution without…
This thesis examines selected issues related to the performance of earthfill embankments constructed on soft clay foundations. The primary objectives of the thesis are: to extend an existing elastic-viscoplastic (EVP) constitutive model to describe the influence of micro-structu…
High-structured carbon blacks are commonly used as electrically conductive additives in electrode slurries that are either processed into solid electrodes for batteries and fuel cells or used as flowable electrodes for semi-solid flow batteries. For these slurries, it is necessa…
The relationship between the geologic processes of extensional tectonics, magmatism, and hydrothermal activity that controls when and where low sulfidation epithermal deposits form is not well established. However, many researchers have noted the similar characteristics of depos…
Subduction zones host the world’s largest earthquakes, but seismic slip is only one style of deformation along the subduction interface. The deformation processes above and below the seismogenic zone are equally fundamental to understanding how relative motion is accommodated du…
