Off-target contamination (or spray drift) during agricultural chemical application, arising from removal of small (diameter < 100 m) droplets from sprays by atmospheric or vehicle-generated cross flows, is investigated experimentally. The primary requirement for realistic wind t…

Many biopharmaceutical projects require the production of recombinant protein in a bacterial host. Conventional procedures used for recombinant protein production (RPP) involve the rapid synthesis of the target protein. This results in the accumulation of unfolded protein, the i…
This thesis describes efforts made towards the synthesis of a biologically stable, luminescent molecular probe, which could be used to investigate in vivo the processing of sugars by β-galactosidases. To this end, a lactose-based probe was designed, featuring a Lanthanide held w…
Thermal treatment is the most common method used by industry to ensure food is safe for consumption and to increase storage life. To ensure safety, food is often over processed, which can significantly affect its nutritional value as well as taste and flavour attributes. In this…
The sponsoring company for this Engineering Doctorate is a manufacturer of passive fire protection materials with about 80 employees. Its primary products are specialist coatings that provide protection from the heat of a fire. Since it is essentially a chemical blending company…
A new process of combining gas injection with compression moulding was developed and studied in this research work. The process is called Gas Assisted Compression Moulding (or GasComp). The principle is based on the injection of nitrogen gas during a conventional compression mou…
The combustion and emissions performance of fuel blends in modern combustion systems has been investigated with the intention of reducing emissions, improving efficiency and assessing the suitability of future automotive fuels. The combustion systems used in this study include H…
Radioactive radon gas, after being released from rocks, soils and building structures, can pose a significant health threat to the building occupants. This is of particular concern in tight HVAC (Heating, Ventilating and Air-Conditioning) serviced buildings where there is re-cir…
Themosetting resins are being used increasingly as matrix materials in advanced fibre-reinforced composites. It is well known that the processing conditions used to manufacture the composite can have a major influence on its mechanical integrity in service. In addition, the proc…
Hydrogen as an energy vector offers great potential for mobile energy generation through fuel cell technology, however this depends on safe, mobile and high density storage of hydrogen. The destabilised multi-component complex hydride system LiBH4 : MgH2 was investigated in orde…
With relatively high gravimetric and volumetric hydrogen storage capacities, borohydride compounds are being investigated for their potential use as hydrogen storage media. A study has been made into the mechanical milling of metal chlorides with sodium borohydride to try to for…
The objective of this research was to investigate adhesion of different fouling deposits with different contact surfaces using atomic force microscopy (AFM). In this thesis, AFM has been employed to measure: (i) The adhesive interactions between a colloidal silica microparticle …
The long-term stability and brittle nature of ceramic bone replacements in physiological conditions makes them prone to mechanical failure. These problems have led to the development of bioresorbable bone replacement materials. Bioresorbable biomaterials are expected to degrade …
The periplasm of E. coli has been recognized a suitable location for the production of large quantities of many industrially important soluble recombinant proteins, and offers some important advantages over both intracellular and extracellular production. The oxidative environme…
This thesis concerns the thermal behaviour and isothermal crystallisation kinetics study of cyclic polyesters and its blends, in particular cyclic poly (butylene terephthalate) (c-PBT). The production of c-PBT is interesting; in fact it is different from production of convention…
Hydrogen is seen as a potential fuel for the future; its choice is driven by the increasing awareness of the necessity for clean fuel. Together with the simultaneous development of “green technologies” and sustainable development, a current goal is to convert waste to energy or …
A commercial Ion Mobility Spectrometer that is designed to detect Chemical Warfare Agents (CWAs), is modified by the addition of a second ion gate, and connected to a commercial Ion Trap Mass Spectrometer (ITMS). The addition of the second gate allows selection of individual ion…
In this thesis an investigation into the behaviour of light when passing through photonic crystals was carried out using numerical methods. Photonic crystals are expensive and difficult to fabricate so there is a requirement for computer simulations that can quickly and accurate…
This research was designed to investigate the properties of aggregate with a new cement coating applied, and to test the effect of including this aggregate in a bituminous road mixture. The investigation was divided into three main areas of study. They were, chemical and physica…
