Kiss Saint Louis University Department of Chemistry   Thu, Dec 3, 2009 2:30 PM   Location: Lopata 101   Abstract: Complex chemical and biological systems exhibit dynamic self-organization with emergent properties depending both on the behavior of the constituent parts and the types and extent of their interactions. We introduce the subject of chemical complexity through the description of macroscale and microscale electrochemical oscillations that occur on multi-particle electrodes.  In the presentation, electrochemical oscillations are described by using the concept of cycle phase and determine how the frequency and precision of the current oscillations on a single electrode depends on resistance and temperature, and how the extent of interactions affects periodic and chaotic synchronization patterns on electrode arrays. With the use of phase models, a general methodology for the control of dynamic states to desired states in populations of rhythmic units is presented.     Mechanical, Aerospace & Structural Engineering, Washington University in St. Louis One Brookings Drive, Box 1185, St. Louis, Missouri 63130 Office Location: 305 Jolley Hall, Phone: (314) 935-6047, Fax: (314) 935-4014   Home |  Academics | Research | Department | Resources © 2009 | Did you find it?
