A scientist named Jason Steffen conducts computer simulations to facilitate these two processes on flight, which then in 2008 he introduced his method known as The Steffen Perfect and the Steffen Method.
American scientists have discovered a new way in which water can freeze.
Water ice is water ice, you might say. Okay, you have rockets, pear ice creams and so on. But if you freeze nothing but pure water—that is, molecules made up of one oxygen atom and two hydrogen atoms—you simply get ice—right?
Researchers have discovered a new form of ice, which could have implications for our understanding of distant, water-rich planets. The findings of the study were published in the journal ‘Physical Review B’. Solid water, or ice, is like many other materials in that it can form different solid materials based on variable temperatures and pressure conditions, like carbon forming diamond or graphite. However, water is exceptional in this aspect as there are at least 20 solid forms of ice known to us. A team of scientists working in UNLV’s Nevada Extreme Conditions Lab pioneered a new method for measuring the properties of water under high pressure. The water sample was first squeezed between the tips of two opposite-facing diamonds — freezing into several jumbled ice crystals. The ice was then subjected to a laser-heating technique that temporarily melted it before it quickly reformed into a powder-like collection of tiny crystals.
