Both steady and dynamic behaviors are dominated by reaction fronts initiated at the interface between different catalytic components. Our analysis links the bifurcation behavior of reactive composites with active boundaries to this transient phenomenon of front initiation. }, year = {1999}, journal = {Physical Review LettersPhysical Review Letters}, volume = {83}, pages = {2857-2860}, month = {10/1999}, isbn = {0031-9007}, language = {English}, }
