Samples were allowed to align overnight at room temperature by placing a 10 uL droplet between two wax filled glass capillary tubes. The resulting fibre bundle was placed on a goniometer head and X-ray fibre diffraction data was collected using a Rigaku rotating anode (CuKalpha) and Saturn CCD detector with exposure times of 30-60 s and specimen to detector distances of 50 and 100 mm. The diffraction patterns were examined using mosflm and converted to tiff format for analysis using CLEARER. 15
