Non-Linear Chemical Systems


Temporal rhythms and spatial patterns commonly observed in nature are present in highly non-linear chemical reactions such as the Belousov-Zhabotinsky (BZ) reaction. An example of our research is that on new methods for chemical information conversion systems and for evaluating microreaction environments by using the BZ reactions in gel, and oscillatory reactions in immobilized enzyme membrane. Other research relates to chemical computing systems for sensing and processing photo- and chemical-information. Based on experimental (the BZ reaction) observation, chaotic behavior of non-linear chemical systems is also being studied to develop new measuring and controlling technologies which take the effect of noise into consideration as well.
