on the same day!
we all know that ice comes in cubes, but what I did not know
until today was that only 17 different phases, or forms of ice have been
observed on a molecular level, new research out of the U.K. suggests there might be an
18th form under very specific conditions, cubes or squares are the
new shape of ice, it turns out that when you sandwich a droplet of water
between two sheets of graphene at 10,000 times atmospheric pressure (one atmosphere is the pressure
of the atmosphere at sea level), the atoms in the water molecules will
straighten themselves out into a perfectly square grid, foregoing their favored
snowflake shape for something that looks more like graph paper,
you can see the ice form in the video, usually when water
freezes into ice, the atoms in water rearrange themselves into a hexagonal or
tetrahedral lattice, which repeats over and over again, forming a natural
crystal, but in high pressure situations, water apparently takes on different
forms, "What's really odd about it is, it loses this tetrahedral
structure," researcher Alan Soper told NPR, "That is the thing that's quite
surprising, because I don't think it's been observed
before." graphene, never heard of it until this morning, then I
read about it twice!
