The gigapascal, symbol GPa is an SI unit of pressure. It is equal to 1,000,000,000 pascals (Pa), or about 10000 atmospheres. The International System of Units (symbol: SI) (for the French phrase Système International dUnités) is the most widely used system of units. ... Pressure (symbol: p or P) is the measure of the force that acts on a unit area. ... The pascal (symbol Pa) is the SI unit of pressure. ...
Categories: SI derived units An SI prefix is a prefix which can be applied to any unit of the International System of Units (SI) to give subdivisions and multiples of that unit. ... SI (disambiguation). ...
Mao's team compressed water between a pair of diamond anvils to a pressure of 17 gigapascals (170,000 times normal pressure at sea level), then bombarded it with high-energy x-rays.
The key was that the team stumbled on the right energy level of x-radiation, about 10,000 electron volts under a pressure of at least 1 gigapascal, for the structure to form and retain its integrity.
Researchers predict that the new alloy may provide information about the behavior of water in extreme temperature and energy conditions, as well as potentially having uses in developing new rocket fuels, since it must contain a large amount of energy to exist.
