(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. |
