Surface enhanced Raman spectroscopy was used in conjunction with cyclic voltammetry to probe the initial stages of the deposition and dissolution of calcium carbonate. Gold nanoparticles were synthesised and employed for their SERS activity so that the weak signal usually associ…
Herquline A and B were isolated from the fungal strain \(Penicillium\) \(herquei\) Fg-372 and have been shown to exhibit potent platelet aggregation inhibitory activities. The unusual and strained structure of herquline A makes it a highly attractive and challenging synthetic ta…
Novel photoactive ruthenium(II) complexes were designed to incorporate existing anti-tuberculosis drugs, isoniazid and nicotinamide, that could be released from the ruthenium(II) cage by photoactivation with visible light. Two sets of complexes were synthesised based on cis-[Ru(…
Proliferative vitreoretinopathy, a potentially blinding condition, involves excessive proliferation of retinal pigment epithelium (RPE) cells and is the main complication following retinal detachment (RD). Complicated cases of RD are treated with silicone oil (SiO) tamponades wh…
The work presented in this thesis focuses on the effect on structure and properties of the rhombohedral (R) perovskite system, Bi(Ti3/8Fe2/8Mg3/8)O3 (BTFM), when solid solutions with CaTiO3 (CTO) are made. Bismuth-based perovskites are established as candidates to replace the pi…
This thesis is divided into two chapters detailing research on applying microwave methodology to access aminated nucleosides in significantly reduced time frames, and applying the Belluš-Claisen reaction to produce non-proteogenic dipeptides. 1. Amination of Nucleosides Using Mi…
The determination of pesticides and related materials in food and environmental samples is important and presents an enduring challenge to analytical chemists. For practicality it is important that as many pesticides as possible are compared using a common technique. Mass spectr…
Ceria nanoparticles (NPs), due to their widespread applications, have attracted a lot of concern about their toxic effects on both human health and environment. Cerium occurs in two oxidation states, Ce (III) and Ce (IV), and has the unique ability to readily switch between thes…
This study is primarily concerned with the application of energy landscape theory to problems in molecular science. Due to the diverse nature of the research undertaken, the thesis is divided into two parts. In the first part, the energy landscapes of the BLN-69 and G\={o}-69 mo…
Selective hydrogenation of a multi-functional compound to achieve high yield of a particular product is often involved in the production of fine chemicals and pharmaceuticals. The control of selectivity can be difficult and can be affected by a number of variables such as the in…
The amphidinolides are macrolide natural products isolated from marine dinoflagellates of the genus Amphidinium and most of them display potent cytotoxic activities in vitro. Amphidinolides C-C3, F and T1-5 represent attractive synthetic targets due to a combination of potent bi…
In this thesis electron microscopy was employed to characterise the nanoscale and atomic scale structure and chemistry of organic and inorganic materials. In chapter 4, the thin film morphology of the organic blend of [poly(9,9-dioctylfluorene- co-benzothiadiazole)] (commonly re…
The selective oxidation of organic compounds is one of the most attractive transformations for both, industry and academia. Industrial interest stems from the potential application of such oxidation methodologies in the economic, greener synthesis of valuable products, whereas a…
This thesis describes several approaches to the synthesis of dihydrooxazoles (oxazolines) by the cyclisation of unsaturated amides. The first major approach to the synthesis of substituted dihydrooxazoles is the CuI-catalysed cycloisomerisation of terminal propargyl amides. The …
Body fluid identification (BFID) forms a crucial aspect within forensic investigations. BFID is particularly important where the origin of a DNA profile is also needed e.g. sexual assaults. The aim of this work was to develop a RNA-based BFID for use in forensic casework. The te…
This thesis illustrates the behaviour of cellulose ethers during powder processing, compaction and drug release, as these are frequently employed in the fabrication of compressed hydrophilic matrices. The handling operations can give rise to the electrification of powder particl…
Phosphate glass fibre polymer composites have the potential to be utilised as degradable orthopaedic implant devices with modifications to the glass fibre composition allowing for materials with tailorable mechanical properties and degradation rates. Accordingly such materials c…
