Self-assembled nanocrystals discovered in Chelyabinsk meteorite
Current interest in nanomaterials is focused mostly on artificial materials fabricated for various applications. However, naturally occurring nanocrystal arrays, like those recently found in the meteorite that fell near Chelyabinsk in Russia on 15 February, 2013, can provide some new insights into the nature of nanomaterials, including the conditions for their natural occurrence. Here we report...
متن کاملChelyabinsk airburst, damage assessment, meteorite recovery, and characterization.
The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an area with a population exceeding one million. Because it occurred in an era with modern consumer electronics, field sensors, and laboratory techniques, unprecedented measurements were made of the impact event and the meteo...

متن کاملJadeite in Chelyabinsk meteorite and the nature of an impact event on its parent body
The Chelyabinsk asteroid impact is the second largest asteroid airburst in our recorded history. To prepare for a potential threat from asteroid impacts, it is important to understand the nature and formational history of Near-Earth Objects (NEOs) like Chelyabinsk asteroid. In orbital evolution of an asteroid, collision with other asteroids is a key process. Here, we show the existence of a hig...
متن کاملMicro and Nanoscale Studies of Shock Features within the Chelyabinsk LL5 Meteorite
Shock effects within meteorites are the products of impacts and collisions in the asteroid belt that eventually led to the ejection of the meteorite from its parent body. These collisions produce shock waves, which in turn lead to formation of high-pressure phases and deformation features within the host meteorite. The (P,T,t) history of the shock process can be deduced by studying these high-p...
