Figure 1.

(a) Schematics of shear rheology and rheo-SALs setups to obtain the shear rheology and scattering patterns of the precursor at different temperatures and shear rates. (b) Shear rheology (steady flow procedure) of the precursor at 15 and 25 °C, exhibiting Newtonian behavior. The insets show representative isotropic scattering patterns in a sheared precursor (~550 s⁻¹) at 15 °C and 25 °C. (c,d) Cryo-EM images of the precursor at 15 °C and 25 °C, displaying mostly spherical micelles at 15 and 25 °C. Some dispersed wormlike micelles were observed at 25 °C (see black arrows in (d)).
