Abstract:
2015 - 2016<br>The focus of this study is to design new nano-modified epoxy adhesives using carbon nanofillers such as carbon nanotubes, carbon nanofibers and exfoliated graphite. Kinetic analysis, transport properties, dynamic mechanical properties and electrical properties have shown to be a powerful means for understanding molecular structure and phase composition of the formulated nanocomposites. Kinetic analysis, performed by using an advanced iso-conversional method and the Kamal’s model-diffusion controlled respectively, has shown which, in epoxy resin, based on the tetrafunctional epo

Traitedness has been described as the “the degree to which a particular trait structure is approximated in a given person” (Tellegen, p. 28, 1991) and has been hypothesized as one explanation for findings of weak trait-behavior relationships. That is, if traits are differentially applicable to different individuals, then trait-behavior relationships may be moderated based on the strength with which an individual fits with a given trait model. This study used moderated multiple regression to test the moderating effects of four different traitedness indicators to increase the predictio

Polymer composites research designed for orthopaedic applications are commonly focused on Ultra high molecular weight polyethylene (UHMWPE) reinforced by a variety of different nanoparticles. However, the high melt viscosity of UHMWPE renders conventional melt mixing techniques impossible for composite manufacturing.

Abstract:
L’utilisation de composites à matrice thermodurcissable et fibres continues est en constante progression dans le secteur aéronautique, ferroviaire, et automobile. Afin d’améliorer les composites obtenus, notamment leur résistance à l’impact et leur conductivité électrique, des nanocharges organiques ou inorganiques peuvent être ajoutées. Les nanotubes de carbone (CNT) font partie des candidats les plus prometteurs pour le renforcement de composites à multi-échelle. Cependant, il s’avère difficile de contrôler la dispersion, la répartition et l’orientation des CNT, après les avoir mélangés aux

Abstract:
The thesis takes inspiration from the worldwide issues related to the shortage of critical raw materials (CRMs) and the need of finding sustainable alternatives to CRMs within fields and sectors strategic to the well-being and economy of industrialized countries. The research activity has been focused on the fabrication of Cu-matrix composites reinforced with carbon nanofillers, nano-graphite and graphene in particular. This class of composites attracts considerable interest as a consequence of the broad spectrum of applications Cu-MCs could find due to their thermal and electric conductiviti

Abstract:
Ultra high temperature ceramics (UHTC) are candidate materials for high temperature applications such as leading edges for hypersonic flight vehicles, thermal protection systems for spacecraft, and rocket nozzle throat inserts due to their extremely high melting points. Tantalum and Niobium Carbide (TaC and NbC), with melting points of 3950°C and 3600°C, respectively, have high resistivity to chemical attack, making them ideal candidates for the harsh environments UHTCs are to be used in. The major setbacks to the implementation of UHTC materials for these applications are the difficulty in co

Abstract:
Spent oil based drilling fluid and cutting wastes are global liabilities due to their hazardous hydrocarbon content which impacts negatively on flora, fauna, and global carbon footprint. The formulation of two demulsifiers to ensure chemically enhanced phase separation of this waste into oil, water and solid components was successfully carried out in addition to recycling the solid phase into PA6 nanocomposite materials. Initial characterisation of the untreated waste was carried out by Fourier Transform Infra Red (FTIR) for total petroleum hydrocarbon (TPH) analysis, Inductively coupled plasm

Abstract:
Organic coatings are frequently applied to metals, often in circumstances where there is a need to protect the substrate from corrosion or to improve the aesthetic quality of a product. Increasingly, coatings are also expected to provide additional functionality, such as anti-bacterial properties. Concurrent with the need to satisfy ever more demanding specifications, coating formulators are being obliged to comply with stringent environmental legislation. A research area which may benefit the development of coating formulations is that of nanocomposite synthesis, in which the composite additi

Abstract:
Over the past two decades one class of oligomers, polyhedral oligomeric silsesquioxanes (POSS), has attracted considerable attention because of their unique hybrid organic/inorganic molecular structures and nanoscopic sizes. While surface and interfacial properties may play a key role in many potential POSS applications, relatively little is actually known about the surface properties of POSS. This dissertation provides studies of the interfacial aspects of both POSS molecules and POSS/polymer blends at the air/water interface (A/W) through surface pressure-area per molecule (π-<i>A</i>) isoth

Abstract:
This PhD thesis investigated the incorporation of Polyhedral Oligomeric Silsesquioxanes (POSS) in thermoplastic base materials via melt-blending procedures. Particularly, a focus is taken on the enhancement of the thermal resistance through the addition of different types of POSS on two popular engineering plastics known by their low thermal stability, one being a semi-crystalline copolymer i.e. polyoxymethylene (POM) and the other an amorphous copolymer i.e. acrylonitrile butadiene styrene grafted with maleic anhydride (ABS-g-Ma).

Abstract:
Carbon fibre reinforced polymer (CFRP) composites are high performance materials which are widely used in various applications, such as aircraft and aerospace structures, satellites, advanced marine vessels, fuel tanks, sports equipment, high-end automobile structures and many other strength/weight critical applications. It is well known that CFRP composites are stronger in tension (in the fibre direction) than in compression, typically 30-40% higher. This is due to the fact that the compressive strength depends on the properties of the matrix and quality of the laminate, such as alignment of

Abstract:
Carbon dioxide internal corrosion is one of the most common degradation mechanisms occurring in oil and gas exploration and production environments when carbon steel is the material of construction. Both general and localized attack can lead to severe production cuts and safety incidents and these are commonly mitigated via the use of corrosion inhibitors, the deployment of which significantly increases the operational expenditure. When environmental conditions are favourable, a naturally growing corrosion product known as iron carbonate precipitates onto the internal pipe wall providing prote
