The synthesis and characterisation of functionalised polyazamacrocycles and their subsequent immobilisation into porous materials were investigated and reported in this thesis. The incorporation of polyazamacrocycles into porous materials offers the potential to enhance their biomimetic and environmental properties with tuneable microenvironments around the macrocycles. Nine polyazamacrocycles have been synthesised that are functionalised with vinyl, pyridyl, carboxylate and iodide pendant arms in order to immobilise them into porous materials. Of these macrocycles nine metal complexes were su

This research involves the development of a totally new approach to thermal analysis in which microwave energy is used not only to heat the sample but also to detect thermally induced transformations via the effects of changes in its dielectric properties.

Microwave thermal analysis (MWTA) is a technique for studying the efficiency of the conversion of microwave to thermal energy by measuring the microwave power-temperature relationship

The structure’s porosity and periodicity provide control over both light (photonic effects) and fluid flow (wetting effects).

Abstract:

The objective of this thesis is to determine if the single sided resistance spot weld (RSW) can be used as a feasible connection method for cold formed steel (CFS) shear walls subject to lateral force of either seismic or wind loads on mobile shelters. The research consisted of three phases which include: a design as a 3D BIM model, connection tests of the resistance spot weld, and full-scale testing of the designed solid wall panels. The shear wall testing was conducted on specimens with both resistance spot weld and self-drilling screws and the results from tests gave a direct comparison of

Abstract:

Manganese oxides and related mixed manganates have long been the subject of research interest, due to their diverse properties, such as cation exchange and molecular absorptive characteristics, in addition to excellent electrochemical and magnetic properties. Some of this research interest has stemmed from the observation of magneto-electric coupling (i.e. change in magnetic state via application of an electric field) in manganite perovskites. However, magneto-electric coupling originating as a consequence of magnetic frustration, has given rise to considerable research attention being focusse

Abstract:

This thesis explores the impact of material objects on people’s identity at work. I address the significance of this question, arguing that materiality, particularly the place it holds in the lives of individuals, has been less considered in relation to people at work than in other disciplines such as consumer studies. My research questions are: to consider how people conceptualise objects at work, to ask how objects and people are mutually implicated at work and to identify how this interactivity impacts on people’s identity at work. I review studies on material objects in organizations and s

Abstract:

The main question and purpose of this study was to pinpoint a sustainable method on developing an evaluation checklist for teaching materials in the English language programmes. The answer of the main question is rejoined through three sub-questions about the sources for the checklist, identifying the design guidelines and offering a validation method for the developed checklist. Design-based research methodology was utilized through three main phases: analysis and exploration, design and construction and evaluation and reflection where the last phase comprised cycles of formative review of th

Abstract:

Mineral trioxide aggregate (MTA) is a Portland cement (PC)-based endodontic material used for sealing root canals. This study investigated the effect of calcium sulphate additions for improving the undesirably-long setting time of MTA-like dental materials, whilst maintaining the mechanical, biological and sealing properties. 10wt%PoP accelerated initial setting times of grey and white model cements and MTA from >6h to <40min, and did not significantly change compressive strengths and relative porosities with long-term storage in media. Cement pastes containing PoP may „false‟ set or stiffen t

Abstract:

The present project is aimed to analyze the steel structure from an evolutionary point of view. The study¿s context has been the 20th century on the Catalan capital city in order to see how the historical, normative and methodological changes have set a new expression for the city. Once a division of the century in specific periods has been made, we have started to analyze the historical context. A civil infrastructure, a set of regulations or even a calculation methodology have to be perfectly set in a context; in fact, it would be pointless to talk about the previous issues if we had not p
