DESCRIPTION:Many phenomena of biological importance involve synchronizatio
 n of oscillatory components. We explore here\, in several geometries\, the
  behavior of diffusively coupled\, nanoliter volume\, aqueous drops contai
 ning the reactants of the oscillatory Belousov-Zhabotinsky (BZ) reaction. 
 A variety of synchronous regimes are found\, including in- and anti-phase 
 oscillations\, stationary Turing patterns\, and more complex combinations 
 of stationary and oscillatory BZ-drops. A differential equation model base
 d on a simplified description of the BZ chemistry and diffusion of messeng
 er species reproduces a number of the experimental results. Materials scie
 nce applications and possibilities for a chemical computer are discussed.
