Frozen water takes on intricate multi-helixed shapes when confined in tiny spaces at high pressures
Abstract:
For a simple collection of hydrogen and oxygen atoms, water has an astounding repertoire of contortionist tricks when frozen. It works particularly well under pressure. In bulk quantities, there are 15 known forms of ice, only a few of which occur at normal atmospheric pressure. "There are so many unique things about water," says Xiao Cheng Zeng, a chemist at the University of Nebraska-Lincoln. Zeng decided to check out ice's act when it is forced into microscopic containment—in this case, into carbon nanotubes less than 2 nanometers in diameter. He and his colleagues Jaeil Bai and Jun Wang have found that ice has a whole new repertoire when it's pushed into a tight spot.
