(a) Normalized forward scattering at T = 77 K versus CPA solution critical cooling rate (CCR) as determined from fits to the data in Fig. 2(c) and fits to the critical cooling rate (CCR) versus CPA concentration data (Warkentin et al., 2013) shown in Supplementary Fig. S3, given by (5) with parameters β given in Supplementary Table S1. The CPA concentrations corresponding to critical cooling rates of 1 K s−1 range from ∼36%(w/w) for ethanol to ∼57%(w/w) for ethylene glycol. Critical cooling rate versus concentration data are not available for 2-propanol, MPD and polypropylene glycol. (b) Volume contraction Δv/v = [v(77 K) − v(298 K)]/v(298 K) in % for rapid cooling from room temperature to the glassy/vitreous/amorphous phase versus the critical cooling rate of the CPA solution. |
