This Thesis presents a study on feasibility of continuous extrusion processing for the manufacture of fine-celled plastic/wood-fiber composite foams. The main benefits of incorporating wood-fibers in plastics are the increased stiffness and lowered cost of the resulting composit…

The use of antisenescence compounds to precondition seedlings was studied in white pine (Pinus strobus L.). In a preliminary study, the effectiveness of eight compounds were tested by their ability to prevent desiccation-induced membrane leakage in Phaseolus vulgaris . When fed …
The first area of study is the use of skin adhesive bioelectrode hydrogels as ground plate electrodes for ophthalmic iontophoresis applications. The work provides a basis of understanding the relative contributions made by ionic monomers (such as sodium s-(acrylamide)-2-methyl p…
Fifteen Miscanthus genotypes grown in five locations across Europe were analysed to investigate the influence of genetic and environmental factors on cell wall composition. Chemometric techniques combining near infrared reflectance spectroscopy and conventional chemical analyses…
The primary objective of this work is to relate the biomass fuel quality to fast pyrolysis-oil quality in order to identify key biomass traits which affect pyrolysis-oil stability. During storage the pyrolysis-oil becomes more viscous due to chemical and physical changes, as rea…
Several cationic initiator systems were developed and used to polymerise oxetane with two oxonium ion initiator systems being investigated in depth. The first initiator system was generated by the elimination of a chloride group from a chloro methyl ethyl ether. Adding a carbony…
This thesis investigates the cost of electricity generation using bio-oil produced by the fast pyrolysis of UK energy crops. The study covers cost from the farm to the generator’s terminals. The use of short rotation coppice willow and miscanthus as feedstocks was investigated. …
A hot filtration unit downstream of a 1kg/h fluidised bed fast pyrolysis reactor was designed and built. The filter unit operates at 450oC and consists of 1 exchangeable filter candle with reverse pulse cleaning system. Hot filtration experiments up to 7 hours were performed wit…
An initial aim of this project was to evaluate the conventional techniques used in the analysis of newly prepared environmentally friendly water-borne automotive coatings and compare them with solvent-borne coatings having comparable formulations. The investigation was carried o…
