Fig. 3. SANS scattering and cryo-TEM images for solutions at high pH. (a) (d,d)-2NapFF; (b) (mix)-2NapFF; (c) (l,d)-2NapFF; (d) (rac)-2NapFF. In all cases, the black circles represent the SANS data and the blue lines show the fit to the data. For the cryo-EM, the scale bar represents 200 nm. The arrow in (d) highlights a thin-walled nanotube.
