Record #174562:

As hot as ice / Zeeya Merali.

Title: As hot as ice / Zeeya Merali.
Author(s): Merali, Zeeya.
Date: 2006.
In: New Scientist. (2006.), Vol. 188(2531/2532) (2006)
Abstract: Reports creation of ice at room temperature by applying electric fields to lukewarm water. Describes earlier attempts and computer simulations suggesting electric field could help because of water molecules' polarity. Describes experiments using fields of 10⁶ V/m, which exist widely in nature, e.g., in clays, across nerve cell membranes and on proteins and polysacchsarides. Reports reaction, and debate over whether it is actually ice, since crystalline structure not established. Phenomenon may explain "memory effect" in which nucleation of ice crystals onto clay particles in clouds occurs at higher temperatures if particles have previously been nuclei. Ice may survive temperatures above freezing in electrically charged crevices in clay.
