Phys. Rev. Lett. 93, 188302 (2004) [4 pages]Excitable CO Oxidation on Pt(110) under Nonuniform Coupling
See accompanying Physics Focus A new feedback scheme for guided spatiotemporal pattern formation in reaction-diffusion systems is introduced. In contrast to previously established control methods, we present a coupling protocol that is sensitive to the presence of coherent structures in the medium. Applying this feedback to the catalytic CO oxidation on Pt(110) in both experiments and numerical simulations, we show that temporal evolution and spatial extension of self-organizing objects can be efficiently controlled. © 2004 The American Physical Society URL:
