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
Adamatzky, A., & de Lacy Costello, B. (2002). Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton. Naturwissenschaften, 89(10), 474-478. https://doi.org/10.1007/s00114-002-0363-6

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.
