微粒子沈殿帯が描く時空間構造

抄録

When the aqueous solution containing an electrolyte contacts the gel containing another electrolyte, particles can precipitate and form stripe patterns in the gel, which is well known as the Liesegang phenomenon. The patterns are static and stationary in the sense that the formed precipitation objects stay at the given position. Precipitation patterns can move if the complex formation of precipitate is possible. In this report, spatial and temporal change in pattern formation of precipitate and the effect of the electrolyte concentration and temperature on dynamic pattern formation of precipitate were discussed.
