“…However, continuous changes in the area of contact between T cells and antigen-presenting cells have recently been reported (34). On the other hand, mechanochemical oscillations attributed to a solutal Marangoni effect have been observed at a liquid/liquid interface with transfer of solutes (35).…”

“…Figure 3b indicates that the relationship between the angular velocity of wave-like motion and the concentration of CTAB seems to be a positive response, the greater the amount of CTAB, the faster the angular velocity would be. Nakache et al 15 had also reported a similar relationship between interfacial tension and concentration of surfactant.…”

“…[2][3][4][5][6] In the system of oil/water liquid membrane, the investigations of the relationship between the potential oscillation and the interfacial tension change is quite important, [7][8][9][10][11][12][13][14] because of the new information that it could produce. Unfortunately, relatively few papers are devoted to the study of mechanism analysis, [15][16][17][18][19] although the selfmotion is very common in biological system, for example, heart beat. It is difficult to obtain a long period of self-motion with good reproducibility due to Marangoni effects 20 or the non-uniformity of the solute concentration in the oil/water phases, which could cause conversion of energy.…”

Este estudo descreve o movimento oscilatório de uma interface água/óleo em um sistema em que a fase óleo era composta por uma mistura de nitrobenzeno, ácido pícrico e etanol, enquanto a fase aquosa era composta por uma solução de CTAB (brometo de cetiltrimetilamônio). A interface apresentava diferentes tipos de movimentos como aleatório, ondulatório e tipo gangorra, que eram afetados por condições experimentais como a concentração dos reagentes e a geometria do vaso de reação. Um mecanismo é proposto para explicar estes movimentos oscilatórios.A macroscopic interface self-motion appearing on an oil/water liquid membrane was clearly observed. The oil phase was a mixture solution containing nitrobenzene, picric acid and ethanol, whereas the aqueous phase was a solution of CTAB (cetyltrimethylammonium bromide). The interface displayed different types of motion, such as random, wave-like motion and teeterboardlike motions, which were affected by experimental conditions like concentration of reactants and geometry of the reaction vessel. A possible mechanism to explain these motions was also proposed.

“…Especially, there have been much work on the oscillation in liquid/liquid interface or the liquid membrane systems. Following the pioneer work on the electrical instability at an oil/water interface by Dupeyrat and Nakache, 3,4 the oscillations of the interfacial potential difference or the interfacial tension in two-phase systems have been investigated. [5][6][7][8][9][10][11][12] Further, the oscillations of the membrane potential or the current in three-phase liquid membrane systems have been investigated extensively.…”

Two liquid membrane oscillators composed of aqueous solutions containing cetyltrimethylammonium chloride (CTACl) and alcohol, W1 and W1′, a nitrobenzene solution containing picric acid, O, and pure water phase, W2, were connected through O and W2 as common phases. Two glass tubes including W1 and W1′ were inserted into the O/W2 interface. Both membrane potential differences between W1 and W2 and that between W1′ and W2 were recorded using a pair of Ag/AgCl electrodes located near the orifice of each tube. The oscillations of two membrane potentials synchronized each other when the distance between the tubes was less than 10 mm. The synchronization was attended by the propagation of a potential pulse from one side to another with an interval of approximately 70 ms at a distance of 10 mm. It was examined whether the propagation of the potential pulse was due to electric conduction in bulk phases, or due to the interfacial conduction by several experiments in the addition of indifferent electrolytes or nonionic surfactant. Consequently, it has been demonstrated that the propagation of oscillation pulse was dominated mainly by the interfacial conduction process, and additionally by the bulk ionic conduction and that the interfacial diffusion and distribution of Cl -played a crucial role.
