Evidence Suggests a Possible New Phase of Ice Researchers at the National Synchrotron Radiation Research Center (NSRRC) announced that they have obtained spectroscopic evidence suggesting that a possible new phase of ice may exist at temperatures between 4 K to 50 K, under high pressure.This discovery was made while a team of researchers led by Dr. Yong Q. Cai were investigating the ordering of hydrogen bonds in H2 O under high pressure and at extremely low temperatures. The team confirmed the density functional theory (DFT) calculations under these conditions which correctly account for the pre-edge feature of ice. However, quite unexpectedly they also obtained data indicating substantial spectral changes from ice IX, suggesting a significant change of the H2 O framework in this P-T regime. In short, the exciting prospect of the formation of a possible new ice phase.
