Figure 2
(a) SAXS curves of the C₃₉₀H₇₈₂ sample recorded after cooling from the melt at different cooling rates, β. (b) Crystalline lamellar thickness, L_c, as a function of β. The red lines indicate the expected lamellar thicknesses of the integer-folded forms F₂, F₃, F₄, and F₅. (c) SAXS curves recorded during in situ heating of C₃₉₀H₇₈₂, previously cooled at β = 1000 K s⁻¹, using the integrated nanocalorimeter;. (d) Temperature dependence of L_c, together with the corresponding nanocalorimetric signal. A baseline correction was applied to the nanocalorimetric signal in order to emphasize the thermal effect associated with the phase transition. The SAXS curves in panels (a) and (c) are vertically offset for clarity.
