Sensors for early warning of post-harvest spoilage in potato tubers (2002)
Presentation / Conference Contribution

Post-harvest spoilage of potato tubers results in approximately 9 million annual loss in the UK alone. In this paper, we report work completed with funding from the British Potato Council to develop an electronic sensor system (e-nose) to enable the...

Highly sensitive mixed oxide sensors for the detection of ethanol (2002)
Journal Article

Sensors consisting of mixtures of tin dioxide and zinc oxide powders in a range of proportions were constructed. Each mixture was applied to an electrode-bearing alumina substrate either as a paste, or by screen printing. The responses of these senso...

The differentiation of biodegradable and non-biodegradable dissolved organic matter in wastewaters using fluorescence spectroscopy (2002)
Journal Article

The chemical and biochemical oxygen demand values of a number of synthetic and wastewater samples were determined using fluorescence spectroscopy. Treated and untreated sewage samples were obtained from a local sewage treatment works while synthetic...

Experimental reaction-diffusion pre-processor for shape recognition (2002)
Journal Article

We have produced an experimental implementation of a massively-parallel reaction-diffusion processor which performs one of the most essential parts of shape recognition - construction of a skeleton. A skeleton is a unique, stable and invariant repres... Read More about Experimental reaction-diffusion pre-processor for shape recognition.

The synthesis of 3-octadecyl- and 3-docosylpyrrole, their polymerisation and incorporation into novel composite gas sensitive resistors (2002)
Journal Article

3-Octadecylpyrrole and the novel 3-docosylpyrrole were synthesised in high yields. These monomers were polymerised with various oxidising agents to produce a range of 3-octadecylpolypyrroles and 3-docosylpolypyrroles with different counter-ions. Thes...

Conducting polymers as coatings: Electrochemical and density functional theory investigations of the polymerisation (2002)
Journal Article

Electroactive materials such as polypyrrole and polythiophene have many applications including their use as coatings in the metal finishing industry. Electrochemical and density functional theory (DFT) studies of a series of derivatised thiophene mol...
