“Advances in oscillatory catalytic reactions”
Numerous processes in physical chemistry and related sciences take place in cycle, with consecutive alternations in time. Widely known as oscillatory or oscillating reactions, such processes are explored as nonlinear phenomena, but their potential in various applications became recognized only recently, almost 100 years after the discovery of the first homogeneous oscillatory reaction.
This lecture will discuss the results of contemporary research focused on the application of oscillatory reactions in the design of new materials, devices and technologies. The CO oxidation on Pt surfaces is the bright example of extensively explored heterogeneous oscillatory reaction. Attempts were made to use oscillating reactions in detecting traces of CO in the air by special sensor technology. Also, wide spectrum of analytical applications of oscillatory reactions was developed, with unexpected robustness and high sensitivity toward evaluation of pharmaceutically active compounds. Advantages of fuel cells with electro-catalytic oxidations in oscillating regime were reported, too. Self-oscillating gels were developed to be used as components of micro devices (actuators) or to achieve controlled periodic drug delivery. Oscillatory reactions are also central figure in attempts to develop chemical computing systems as devices for fast parallel information processing.
