Reactions occurring at different surface sites on the same nanocatalyst can «communicate» with each other in ways that are very similar to catalytic allostery in enzymes. (nanotechweb.org)
Different surface sites can «talk» to each other in ways that are very similar to catalytic allostery in enzymes — nature's most efficient nanoscale catalysts. (nanotechweb.org)
When they examined their rate maps for dissolving calcite and zinc oxide crystals, Lüttge and Fischer found «rhythmic fluctuations of the reactive surface site density,» or dissolution pulses that spread like rings from etch pits and screw dislocations, much like ripples that spread from the point where a pebble is dropped into a pond.
