These observations may reflect increasing nematic phases (tending toward staircase-like packing) bridging across grains. We formed VDF images using a virtual aperture for 00ℓ spot positions for 15%, 30%, and 50% C30H61OH in addition to the VDF images formed for the pure endmembers (Figure , third row). No contrast attributable to 00ℓ diffraction was observed in the 50% C30H61OH VDF image. Some bright patches were seen in the 15% C30H61OH VDF image, whereas some bright sharp lines of intensity, as seen in the pure C31H64 VDF image, were seen in the 30% C30H61OH VDF image. Again, to further confirm the domain assignment of lamellar ordering of the 00ℓ VDF intensity, we extracted diffraction patterns only from bright regions in the 00ℓ VDF for both 15% and 30% C30H61OH (Figure and S33). The presence of 00ℓ spots in these diffraction patterns, not seen in the average diffraction pattern, confirms some lamellar order within the crystals. This ordering is not to the same extent as we see in the pure C31H64, demonstrating disruption to the lamellae on addition of alcohol to the binary mixture. Histograms of grain size, taken as the grain width, showed no consistent trend across this composition range (Figure , bottom row). The average grain size decreased from 0% to 15% to 30% C30H61OH, but falls broadly between 150-300 nm. Certainly the incorporation of moderate quantities of C30H61OH does not alter the grain size substantially. Notably, the increase in average grain size at 50% C30H61OH may arise from reduced precision in measurements due to the loss of defined boundaries. As no grains were visible in 100% C30H61OH, a 'block' size was measured instead to evaluate any similarity in these blocks and the grains observed in the other compositions. The average size of these blocks in 100% C30H61OH was 507 nm, roughly double the size of the grains seen in the pure C31H64 and binary mixtures, and so we ruled out any correspondence between these features and the tilted grains in 0-50% C30H61OH.
