Fig. 6: Logarithm of the nucleation time as a function of over-compression.
From: Metastable water at several compression rates and its freezing kinetics into ice VII
The nucleation time is assumed as tn = αΔt, with α = 1 for the figure. Changing α only changes the constant of the fit. Our data points with averaged points from refs. 7,17 are fitted using the CNT-based phenomenological model given in Eq. (4) with the three free parameters equal to: log(tmin) = −11.39, a = 5380.17 and b = 2.453e8. Inset: Extrapolation of the CNT model at large over-compression showing an asymptotic limit at the picosecond-timescale. The error bars in pressure are shown while those in time are smaller than the symbol size. They are estimated from the pressure measurements and from the ones given in the literature.
