Proton exchange membrane fuel cell (PEMFC) technology provides a sustainable power solution as it electrochemically converts the chemical energy stored in hydrogen molecules into electricity, heat, and water. The electrochemical reactions occurring in the catalyst layer (CL), ho…
Industrial processing of soft materials involves a wide range of processing histories that change the material’s nanostructure and, therefore, the properties of the final product. Determining the connection between processing, structure and properties represents a grand challeng…
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 constant progression of society that desires more advanced, more efficient, and more appealing products requires constant need for development of new technologies and novel ways to produce new products. In the area of multi-layered polymeric systems, the need is no different…
The flow behaviour of liquid metals (Sn, Pb and Sn-Pb eutectic) under different shearing conditions is investigated. Experiments were performed with two designs of concentric cylinder viscometers: rotating the inner cylinder (Searle) and rotating the outer cylinder (Couette). Th…
This thesis looks at the study of nanocomposites of Poly(ethylene terephthalate) and organoclays. Two methods of materials blending are investigated for the production of the nanocomposites: solvent blending and melt blending. The main objectives were the investigation of the in…
Novel solutions to offset thermal degradation of polyamide-6 (PA-6) and organoclay (organically modified layered silicates) nanocomposites during melt compounding have been investigated. In this research, a novel chain extender (Joncryl ADR 3400) has been used to improve thermal…
Carbon nanotubes are known as ideal fillers for polymer systems; the main advantage of carbon nanotubes over other nano-reinforcing particles is the combination of superior strength and stiffness with large aspect ratio. Carbon nanotubes may improve the mechanical, electrical an…
Carbon nanotubes (CNTs) have been successfully grafted onto the surfaces of spherical silica gels via a floating-catalyst chemical vapour deposition method. Two types of silica gels were used as substrates; SG6 (6 – 8 nm pore size) and SG26 (26 – 34 nm pore size). The optimum gr…
Melding is a novel process which offers a promising route to creating seamless bonds, by partially curing two laminates in a controlled manner using a Quickstep chamber and subsequently co-curing them. Previous research has focused on melding lap joints in the x-y plane of a com…
Bioethanol is a promising renewable biofuel and wheat is currently the main candidate asthe feedstock for its production in the UK context. The quality of the numerous varieties ofwheat developed in the past by plant breeders has been well examined in terms of bread, biscuitand …
"Using a unification technique introduced and developed by the authors, this unique reference presents rheological data on a large number of polymers in the most concise from - making use of the master curve approach to determine unified curves for each generic type of polymer."…
