Physicists Find First Experimental Evidence of Elusive Critical Point in Supercooled Water
By probing supercooled water with ultrafast lasers before it crystallizes, physicists at Stockholm University observed telltale signs of a long-theorized transition between two liquid states, including surging heat capacity and critical fluctuations. You et al. studied supercooled water at timescales before ice formation by heating high- and low-density amorphous ices using infrared ultrafast laser pulses,…
