“…One-phase bicontinuous (W IV ) systems, when in contact with polar surfaces such as glass, silicon, and clay, undergo ordering near the solid-BME interface (on a sub-microscale), approaching lamellar structure, especially in the presence of shear, due to the dampening of fluctuations. [24][25][26][27][28] Less efficient surfactants produce bicontinuous phases with gyroid structure near the solid surface. 27 A second objective for the current study is to observe whether similar changes occurred for the bicontinuous phase isolated from the SDS/pentanol W III system and placed in a quartz cell, near the bottom, quartz-BME interface.…”
