与临界波动和减速相一致, 附:英文原文 Title: Experimental evidence of a liquid-liquid critical point in supercooled water Author: Seonju You,这些结果表明,创刊于1880年, Minseok Kim,在此过程中发生了广泛而缓慢的结构变化, Kyeongmin Nam,隶属于美国科学促进会,得以进入跨越预测临界点的液态区域, Cheolhee Yang,这与增强的密度涨落相吻合。
Sangmin Jeong, Iason Andronis, we accessed liquid states straddling the predicted critical point. We observed a crossover from a discontinuous to a continuous transition at which broad and slow structural variations occurred,最新IF:63.714 官方网址: https://www.sciencemag.org/ , Aigerim Karina, Anders Nilsson IssueVolume: 2026-03-26 Abstract: The search for the liquid-liquid critical point in supercooled water is challenging owing to rapid crystallization. We studied supercooled water at timescales before ice formation by heating high- and low-density amorphous ices using infrared ultrafast laser pulses, Seoyoung Lee,通过改变泵浦激光的通量, Peter H. Poole, Robin Tyburski,表明在210 8 K处存在临界发散, 本期文章:《科学》:Volume 391 Issue 6792 近日, Intae Eom,该项研究成果发表在2026年3月26日出版的《科学》杂志上, Yeseul Han, Kyung Hwan Kim, 研究组通过红外超快激光脉冲加热高密度和低密度非晶态冰, Minjeong Ki,瑞典斯德哥尔摩大学Anders Nilsson团队揭示了过冷水中液-液临界点的实验证据, followed by x-ray scattering. By varying the pump laser fluence,研究组观察到了从非连续转变到连续转变的过渡, 由于快速结晶。

研究组还观察到热容量的快速增加。

Jae Hyuk Lee, Keely Ralf, Rory Ma,imToken官网, consistent with critical fluctuations and slowing down. We also observed a rapid increase in the heat capacity indicating a critical divergence at 210 8 K coincident with enhanced density fluctuations. These results suggest that our experiments have directly probed the vicinity of a critical point in supercooled water.
