    • Polarized light microscopy images were obtained using a Wild M400 microscope by placing the sample between crossed sheet polarizers. The images were recorded using a 35 mm camera and/or a CCD color camera (Diagnostic Instruments, Sterling Heights, MI).

    • 54-DMPC compositions of the complex fluid (samples were prepared by hydration of the solid components in deuterium-depleted water as previously described) were obtained at a resonance frequency of 46.016 MHz on a Varian Unity Inova 300 spectrometer (7.05T) using a 90deg; rf pulse width (20 ms). Recycle times were sufficient to ensure complete relaxation. The free induction decays consisted of 2048 scans that were multiplied by 50 Hz exponential line broadening before Fourier transform.

In the presence of the field, the sample was cooled to 2 °C and held for 1 h, then gradually (over a 30 minute period) warmed to 25 °C, held an additional 1 h, and then removed from the magnet. Aligned samples were stored at room temperature until taken for X-ray studies. Synchrotron small-angle X-ray diffraction measurements were preformed on the BESSRC undulator beam line (12ID) of the Advanced Photon Source at Argonne National Laboratory. The scattering profiles were recorded with a mosaic detector composed of 9 CCD chips with an imaging area of 15 × 15 cm, with 1536 × 1536 pixel resolution. The area detector images were corrected for background scattering of water by subtracting from the recorded images an area detector image of a water sample obtained with the same total exposure time as for the liquid crystalline sample (5 s). The collected low-angle scattering data were calibrated on the basis of the known positions of silver behenate powder Bragg reflections.
