Meteorite strikes may create unexpected form of silica

When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach ...

First experimental evidence for superionic ice

Among the many discoveries on matter at high pressure that garnered him the Nobel Prize in 1946, scientist Percy Bridgman discovered five different crystalline forms of water ice, ushering in more than 100 years of research ...

Putting iron to the stress test

(Phys.org) —Using an ultrafast laser system, a group in Physical and Life Sciences at Lawrence Livermore National Laboratory have subjected iron to extremely rapid dynamic compression and have shown that the transition ...

Researchers achieve record pressure for solid iron

(Phys.org) —Iron is the most abundant element in Earth's core and the sixth most abundant element in the universe. As a key component of terrestrial planets and exoplanets, iron has been one of the most studied materials ...

Compression experiments lead to shocking results

Using acceleration 1 trillion times faster than a jet fighter in a maximum turn, researchers have gained new insight into dynamic compression of aluminum at ultrahigh strain rates.
