In a reverse microemulsion consisting of water, oil (octane), an anionic surfactant [aerosol OT (AOT)], and the reactants of the oscillating Belousov-Zhabotinsky (BZ) reaction, a variety of complex spatiotemporal patterns appear. These include traveling and standing waves, spirals that move either toward or away from their centers, spatiotemporal chaos, Turing patterns, segmented waves, and localized structures, both stationary and oscillatory. The system consists of nanometer-sized droplets of water containing the BZ reactants surrounded by a monolayer of AOT, swimming in a sea of oil, through which nonpolar BZ intermediates can diffuse rapidly. We present experimental and computational results on this fascinating system and comment on possible future directions for research.
在由水、油（辛烷）、一种阴离子表面活性剂[气溶胶OT（AOT）]以及振荡贝洛索夫-扎博廷斯基（BZ）反应的反应物组成的反相微乳液中，会出现各种复杂的时空图案。这些图案包括行波和驻波、向中心或远离中心移动的螺旋波、时空混沌、图灵图案、分段波以及静止和振荡的局域结构。该系统由含有BZ反应物的纳米级水滴组成，这些水滴被单层AOT包围，在油相中游动，非极性BZ中间体可通过油相快速扩散。我们展示了关于这个迷人系统的实验和计算结果，并对未来可能的研究方向进行了评论。
