Sensors for early warning of post-harvest spoilage in potato tubers (2002)
Presentation / Conference
de Lacy Costello, B., Ewen, R., Gunson, H., Ratcliffe, N. M., & Spencer-Phillips, P. T. (2002, November). Sensors for early warning of post-harvest spoilage in potato tubers. Presented at BCPC Conference 2002 - Pests and Diseases, Brighton, UK

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
de Lacy Costello, B., Ewen, R., Guernion, N., & Ratcliffe, N. M. (2002). Highly sensitive mixed oxide sensors for the detection of ethanol. Sensors and Actuators B: Chemical, 87(1), 207-210. https://doi.org/10.1016/S0925-4005%2802%2900220-4

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...

Experimental reaction-diffusion pre-processor for shape recognition (2002)
Journal Article
Adamatzky, A., de Lacy Costello, B., & Ratcliffe, N. M. (2002). Experimental reaction-diffusion pre-processor for shape recognition. Physics Letters A, 297(5-6), 344-352. https://doi.org/10.1016/S0375-9601%2802%2900289-X

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 fabrication and characterisation of a highly sensitive polypyrrole sensor and its electrical responses to amines of differing basicity at high humidities (2002)
Journal Article

Ammonia is a common feedstock for many chemical processes involving nitrogen compounds. It is a poisonous, colourless gas with a pungent smell and a fairly low odour threshold of approximately 5 ppm. The recommended threshold limit value for human ex...

Journal Article
Smith, J., Cox, P., Ratcliffe, N. M., & Campbell, S. (2002). Conducting polymers as coatings: Electrochemical and density functional theory investigations of the polymerisation. Transactions of the Institute of Metal Finishing, 80(2), 52-55

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...
