posted on 17.12.2015, 03:23 authored by Toshihiko Oka, Hiroki HojoWe report a simple method to produce
a single crystal region of
an inverse bicontinuous cubic (QII) phase of a lipid, 1-monoolein.
By starting with the lipid of the sponge (L3) phase in
the presence of 1,4-butanediol, we can obtain a single crystal region
of the double-diamond QII phase in 1 week by controlled
dilution of 1,4-butanediol. The length of the single crystal region
in a 0.5 mm diameter capillary was on the order of millimeters. X-ray
diffraction images of the region showed diffraction “spots”,
but not “rings” as in powder diffraction. The diffraction
images also changed rotation angle dependently. We could assign Miller
indices to all of the distinguishable diffraction spots from the region.
This method would bring benefits to the basic and applied research
areas of the Q phases.
