15 Time-resolved X-ray diffraction (XRD) of compressed liquid water shows transformation 16 to ice VII in 6 nanoseconds, revealing crystallization rather than amorphous solidification 17 during compression freezing. Application of classical nucleation theory indicates 18 heterogeneous nucleation and one-dimensional (e.g., needle-like) growth. These first 19 XRD data demonstrate rapid growth kinetics of ice VII with implications for fundamental 20 physics of diffusion-mediated crystallization
