Spatial and Temporal Control of Information Storage in Cellulose by Chemically Activated Oscillations. 
Chemical oscillations are exploited to achieve self-expiring graphical information on paper-based supports with precise temporal and spatial control.  Writing and self-erasing processes are chemically activated by exciting nonoscillating Belousov-Zhabotinsky (BZ) solutions infiltrated in cellulose paper filters.  Exhausted supports can be reactivated many times by adding new BZ medium.  Different parameters can be independently controlled to program mono- or multipaced information storage.
