Photolithography was used to create microscopic reacting domains on polycrystalline foils and single-crystal platinum (110) surfaces with inert titanium overlayers. Certain domain geometries give rise to patterns that have not been observed on the untreated catalyst and bring to light surface mechanisms that have no analog in homogeneous reaction-diffusion systems. }, year = {1994}, journal = {ScienceScience}, volume = {264}, pages = {80-82}, month = {04/1994}, isbn = {0036-8075}, language = {English}, }
