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。 According to a recent paper published by Japanese scientists, water ice may be as stable and bulky as marshmallows under negative and cryogenic conditions. Such previously unknown “airgel ice” is a known density The lowest ice. Japan Okayama University of Science and Technology more than 300 kinds of possible crystal structure molecular dynamics simulation to study their properties under negative pressure conditions, proposed the idea of ​​airgel ice. In their opinion, airgel ice is the most stable form of solid water at negative pressures at temperatures close to absolute zero.
