Figure Lengend Snippet: A 2-mm-diameter X-ray capillary (size C, 0.49 wt %) was scanned from bottom to top, every 0.2 mm on the SWING SAXS beamline. Representative patterns are displayed: ( A ) isotropic phase just above the I–N interface, nematic phase ( B ) just below the I–N interface and ( C ) just above the N–L interface, ( D ) lamellar phase just below the N–L interface, and ( E ) in the middle of the lamellar phase region. (Note that in the photograph on the left, colored spots can be seen in the lamellar phase due to diffraction of visible light.)

Article Snippet: For texture observations, samples were filled in flat glass capillaries (Vitrocom) of 100- or 200-μm thickness, 2-mm width, and about 80-mm length.

Figure Lengend Snippet: Acoustic streaming profiles inside the rectangular glass capillary are visualized using streak images. At lower frequencies, more specifically at a 61.7 kHz, b 62.5 kHz, c 63.7 kHz and d 67.3 kHz, acoustic streaming flows results in more directional fluid displacement within the capillary. At higher frequencies of e 220 kHz and f 187 kHz, acoustic streaming-induced flows yield rotating vortices at different planes. In f —i and f —ii, two adjacent vortices are shown side by side because they could not fit in the same frame due their larger spatial distribution in the capillary. Yellow arrows are used to indicate the streaming directions. g The streaming profiles are recorded from the region of interest (ROI) shown with a red rectangle (color figure online)

Article Snippet: Schematic depiction of the a assembled and b side views are shown. c Photograph of an assembled device For the device assembly, two adaptors are positioned to have their capillary ports facing to each other, and two rectangular glass capillaries (5010, Vitrocom, NJ, USA) with 50 mm length, 0.1 mm height, 1 mm width and 0.07 mm wall thickness are inserted to each adaptor as shown in Fig. b.
