Recent Asteroid On Impact Made DIAMONDS..

Welcome back to Tech Splash, today on the channel we are going to discuss how Scientists discover Asteroid impacts make diamond like materials + other related news. Published today in Proceedings of the National Academy of Sciences, the team of researchers found that diamonds formed during a high-energy shock wave from an asteroid collision around 50,000 years ago have unique and exceptional properties, caused by the short-term high temperatures and extreme pressure. The researchers say that these structures can be targeted for advanced mechanical and electronic applications, giving us the ability to design materials that are not only ultra-hard but also malleable with tunable electronic properties.

For the study, scientists from the UK, US, Hungary, Italy and France used detailed state-of-the-art crystallographic and spectroscopic examinations of the mineral lonsdaleite from the Canyon Diablo iron meteorite first found in 1891 in the Arizona desert. Named after the pioneering British crystallographer Professor Dame Kathleen Lonsdale, the first female professor at UCL, lonsdaleite was previously thought to consist of pure hexagonal diamond, distinguishing it from the classic cubic diamond. However, the team found that it is in fact comprised of nanostructured diamond and graphene-like intergrowths (where two minerals in a crystal grow together) called diaphites. The team also identified stacking faults, or “errors” in the sequences of the repeating patterns of layers of atoms. The team found that the distance between the graphene layers is unusual due to the unique environments of carbon atoms occurring at the interface between diamond and graphene. They also demonstrated that the diaphite structure is responsible for a previously unexplained spectroscopic feature.
