The synthesis of novel 3-substituted pyrrole monomers possessing chiral side groups: A study of their chemical polymerisation and the assessment of their chiral discrimination properties (2003)
Journal Article
De Lacy Costello, B. P., de Lacy Costello, B., Ratcliffe, N. M., & Sivanand, P. S. (2003). The synthesis of novel 3-substituted pyrrole monomers possessing chiral side groups: A study of their chemical polymerisation and the assessment of their chiral discrimination properties. Synthetic Metals, 139(1), 43-55. https://doi.org/10.1016/S0379-6779%2802%2901247-X

Novel 3-substituted pyrrole monomers possessing chiral side groups were synthesised. These compounds were successfully polymerised with ferric salts and the polymer materials fabricated into sensors. The sensors were found to elicit differential chan...

Thick film organic vapour sensors based on binary mixtures of metal oxides (2003)
Journal Article
Ratcliffe, N. M., Ewen, R. J., De Lacy Costello, B. P., de Lacy Costello, B., Ewen, R. J., Ratcliffe, N. M., & Sivanand, P. S. (2003). Thick film organic vapour sensors based on binary mixtures of metal oxides. Sensors and Actuators B: Chemical, 92(1-2), 159-166. https://doi.org/10.1016/S0925-4005%2803%2900258-2

Previously, composite sensors incorporating differing proportions of tin dioxide and zinc oxide were reported which exhibited high sensitivity to a range of organic vapours under dry conditions (0% relative humidity, RH). Most importantly, the compos... Read More about Thick film organic vapour sensors based on binary mixtures of metal oxides.

Experimental reaction-diffusion chemical processors for robot path planning (2003)
Journal Article
Ratcliffe, N., De Lacy Costello, B., Adamatzky, A., de Lacy Costello, B., Ratcliffe, N. M., & Melhuish, C. (2003). Experimental reaction-diffusion chemical processors for robot path planning. Journal of Intelligent and Robotic Systems, 37(3), 233-249. https://doi.org/10.1023/A%3A1025414424756

In this paper we discuss the experimental implementation of a chemical reaction-diffusion processor for robot motion planning in terms of finding the shortest collision-free path for a robot moving in an arena with obstacles. These reaction-diffusion... Read More about Experimental reaction-diffusion chemical processors for robot path planning.

A prototype sensor system for the early detection of microbially linked spoilage in stored wheat grain (2003)
Journal Article
de Lacy Costello, B., Ewen, R., Gunson, H., Ratcliffe, N. M., Sivanand, P., & Spencer-Phillips, P. T. (2003). A prototype sensor system for the early detection of microbially linked spoilage in stored wheat grain. Measurement Science and Technology, 14(4), 397-409. https://doi.org/10.1088/0957-0233/14/4/301

Spencer-Phillips was Co-Investigator, the lead biologist in this HGCA-funded multi-disciplinary work, and co-wrote the paper. The grant was based on his expertise in the microbiology of post-harvest spoilage.
