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 logical gates in a reaction-diffusion medium: The XOR gate and beyond (2002)
Journal Article
Adamatzky, A., & de Lacy Costello, B. (2002). Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond. Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 66(4), 6. https://doi.org/10.1103/PhysRevE.66.046112

We exploit the particulars of diffusive wave front interactions in certain types of two-reactant reaction-diffusion medium to construct a laboratory prototype of an XOR gate. In the design, the values of the logic variables are represented by the pre... Read More about Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond.

Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton (2002)
Journal Article

We offer a new approach to computing a shortest collision-free path in a space containing obstacles, using an experimental chemical processor, based on the Belousov-Zhabotinsky (BZ) reaction. The chemical processor was then coupled via optical links... Read More about Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton.

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
Ratcliffe, N. M., Guernion, N., & de Lacy Costello, B. (2002). The synthesis of 3-octadecyl- and 3-docosylpyrrole, their polymerisation and incorporation into novel composite gas sensitive resistors. Synthetic Metals, 128(2), 139-147. https://doi.org/10.1016/S0379-6779%2801%2900551-3

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...
