Description:
Almost 30 years have passed since the discovery of concentric (target) and spiral waves in the spatially extended Belousov-Zhabotinsky (BZ) reaction. Since then, rotating spirals and target waves have been observed in a variety of physical, chemical, and biological reaction-diffusion systems. All of these waves propagate out from the spiral center or pacemaker. We report observations of inwardly rotating spirals found in the BZ system dispersed in water droplets of a water-in-oil microemulsion. These "antispirals" were also generated in computer simulations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vanag, V K -- Epstein, I R -- New York, N.Y. -- Science. 2001 Oct 26;294(5543):835-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Volen Center for Complex Systems, Brandeis University, Waltham, MA 02454, USA. vanag@brandeis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11679665" target="_blank"〉PubMed〈/a〉
