【摘要】：正日本科学家最近发表论文说,在负压和超低温条件下,水冰可能会像棉花糖一样,以蓬松轻盈的形式稳定存在,这类前所未知的"气凝胶冰"是已知密度最低的冰。日本冈山理科大学对300多种可能的晶体结构进行分子动力学模拟,研究它们在负压条件下的性质,提出了气凝胶冰的设想。他们认为,在温度接近绝对零度的负压环境中,气凝胶冰是固态水最稳定的形式。相关论文发表在美国《化学物理杂志》上。
[Abstract]:In a recent paper by Japanese scientists, water ice, known as the "aerogel ice", is known to have the lowest density, like marshmallow, in the form of puffy and light, under negative pressure and ultra-low temperatures, according to a recent paper by Japanese scientists. More than 300 possible crystal structures were simulated by molecular dynamics at Okayama University of Science. Their properties under negative pressure were studied and the assumption of aerogel ice was put forward. They believe that aerogel ice is the most stable form of solid water in a negative pressure environment with temperatures near absolute zero. The paper was published in the American Journal of Chemical Physics.
