Oscillatory phenomena at liquid–liquid interfaces

Dynamic instability at liquid/vapor interface far from equilibrium

“…Self-induced oscillations in similar systems have also been observed [9]. Theoretical efforts have also been made to understand the mechanism in some cases [10,11].…”

Density Oscillators

“…Cluster states and more complex patterns are observed when more than three inner containers are held within one outer container (Miyakawa and Yamada, 2001). The oscillation of the electrical potential, which occurs when a pair of electrodes are placed in the light and heavy fluids, has also been extensively studied (Yoshikawa et al, 1989;Adamčiková, 1992;Upadhyay et al, 1992;Das and Srivastava, 1993;Srivastava, 1994;Srivastava et al, 1994;Villarreyes et al, 2000;Cervellati and Solda, 2001;Rastogi et al, 2005). The oscillation of the electrical potential, which occurs when a pair of electrodes are placed in the light and heavy fluids, has also been extensively studied (Yoshikawa et al, 1989;Adamčiková, 1992;Upadhyay et al, 1992;Das and Srivastava, 1993;Srivastava, 1994;Srivastava et al, 1994;Villarreyes et al, 2000;Cervellati and Solda, 2001;Rastogi et al, 2005).…”

Mechanism of nitromethane liquid membrane oscillator containing sodium oleate

“…In this system, fairly regular oscillations of rather high amplitude (250-350 mV) appear after a certain induction period [2,11,12]. This oscillator was investigated in view of molecular recognition [2,4,11,17] and to establish the mechanism of oscillations of electric potential difference between the aqueous phases [7][8][9][10][11][12][13][14][15][16]. Different approaches to the mechanism of oscillation in this system have already been presented in the literature.…”

“…As mentioned above, the mechanism of oscillators with cationic surfactants has been investigated in detail by many groups and it seems to be well established by now [7][8][9][10][11][12][13][14][15]21,22]. On the other hand, very little is known about the mechanism and properties of oscillators with anionic surfactants [1,20].…”
