Date lightest water – gel-like ice

In the \”normal ice\”, the cooling water at ambient pressure, which is frozen into a solid crystal molecules hexagonal form. But not all kinds of ice will follow this hexagonal structure. Pressure and temperature that may affect the number of water molecules at the level of millions. Occasional hexagonal ice and the atmosphere above the ice cubes are the only two naturally occurring on Earth of such form of ice. Other ice or in the presence of extrasolar planets, or exoplanets exist in the atmosphere. At atmospheric pressure or higher, water molecules will be compressed and then frozen ice becomes greater than the density of conventional solid state. However, when the air pressure decreases, water molecules become similar to a cold marshmallow lower density class, more lightweight gas crystalline state. Up to now, people only know two kinds of ice density: the density of fullerenes in space equivalent to 80% of normal ice; and zeolite of ice, which mimics the zeolite-containing minerals, but the water molecule is like a Lego building blocks of the same column, 50% and 90% of normal ice density. But before but did not find the ice structure lighter. People removed from the refrigerator ice is only one of 17 possible forms of ice exist on 18 kinds of ice is not far from becoming a reality. A research team found that a porous, lightweight \”gas ice\” – ice airgel, which allows people to learn more about how water runs under extreme conditions. Masakazu Matsumoto and team play Okayama University in Japan using molecular \”layer stack\” approach to find new kinds of ice, remove and reconfigure the existing structure of the zeolite ice, making them lighter. They simulate 300 different species of nano-level structure, and to assess how these structures are stable at low pressure. These gaseous ice is stable at zero degrees Kelvin, but increases as the temperature becomes unstable. They found that the smallest ice density gaseous node configurations may be used as a model water molecules, they are as large in the floor and ceiling of the gaseous palace spaced apart like beads. Matsumoto believes that through computer modeling, you can find more like ice, but he said it was difficult to create a very low density of ice in the real world, because of the need low pressure and low temperature conditions. University College London, Christoph Salzmann said that this work will help people understand how the movement of water molecules.
