In Chelyabinsk meteorite discovered nanocrystals olivine

Analysis of one of the fragments of space rock that has recently shocked the world with his powerful explosion of the Southern Urals, Russia has allowed scientists to detect nano-crystals of the mineral olivine. The work was carried out by physicists from the Research and Education Center "Physics of Solid State Nanostructures" in Nizhny Novgorod State University. NI Novgorod (UNN). Details are described in detail in the scientific journal of the University, "Bulletin of the University of Nizhny Novgorod."

Physicists used to study fragments of the meteorite electron microscope. They also performed X-ray analysis, the sample was drilled and crushed it to pieces. As a result, the researchers found a stone spherical nanostructures, which are, in essence, the crystals. These structures could be formed, according to scientists in space under extremely high temperatures and pressures.

Today, physicists around the world to actively create nanocrystals in laboratories. These substances is inherent in a number of extremely useful properties, and it is possible that the results obtained in the study of meteorites "Tchebarkul" scientific data will help physicists who are working to develop high-tech nano-materials, one day make a technological breakthrough, the researchers stressed.

An earlier study of the Chelyabinsk meteorite fragments was performed by scientists in Novosibirsk. They were then able to show that a space object is related to a rare type "chondrites LL5
