Imagine ice at room temperature! Yes, Harvard physicists have shown that it is possible. Diamond coated with sodium helps ice formation at room temperature. This is possible for very thin layers of ice. The thinness is measured in nanometers. The surface of the specially coated diamond keeps the molecules of water in crystalline structure as the latter starts to melt down.
Earlier, Dutch scientists had shown that if ice is placed between a tiny tungsten tip and a graphite surface, ice is formed at room temperature. Further, Kaxiras and Wissner-Gross’s work shows that under normal pressure and temperature this is also possible even over a large area. This piece of discovery would be beneficial in medical history in producing effective medical devices.
Yet apprehensions regarding the abrasive nature of diamond could not be ruled out as it might cause injury to the surrounding tissues.
