1. Interfacial self-organization during electrodeposition of Cu-Sn alloys under oscillatory condition / Auto-organização interfacial durante a eletrodeposição de ligas Cu-Sn em regime oscilatório
A emergência de estruturas espaço-temporais auto-organizadas em sistemas químicos abertos e afastados do estado de equilíbrio termodinâmico resulta da cooperação entre os processos de reação e transporte de espécies ativas e tem se tornado uma área de intensa atividade nos últimos anos. Auto-organização dinâmica na interface sólido/líquido d

2. Cooperative action of coherent groups in broadly heterogeneous populations of interacting chemical oscillators
We present laboratory experiments on the effects of global coupling in a population of electrochemical oscillators with a multimodal frequency distribution. The experiments show that complex collective signals are generated by this system through spontaneous emergence and joint operation of coherently acting groups representing hierarchically organized reson

3. On the Mechanism of Oscillations in the “Beating Mercury Heart”
The discovery of a class of electrochemical-mechanical oscillators—similar to the beating mercury heart -are reported and characterized. Chemical and physical effects on the voltage-time oscillations in these systems have been measured and a mechanism consistent with these effects is given. Interesting cross-catalytic effects involving the electrocapillari
