Figure 7
Intensity of light transmitted through the sample stream 100 µm from the nozzle tip as a function of time, as the stabilizing gas flow is varied. Black dashed line shows the approximate backing pressure of the gas jet. High transmission is indicative of the presence of lamellar phase while low transmission indicates the sample is in a cubic phase. The sample composition is 60:40 MO/water (w/w). (a) Gas backing pressure is reduced slowly to zero prior to collecting data, then increased steadily from 0 psi to 30 psi. A significant increase in intensity is observed, indicating a transition to the lamellar phase. This was repeated three times to show the procedure was reproducible. (b) Gas backing pressure begins at 30 psi and is reduced steadily to zero. The corresponding decrease in transmission indicates reversion to LCP as the gas flow is reduced.
