They discover “unique and exceptional” properties in diamonds formed 50,000 years ago after the collision of an asteroid

Scientists believe that the newly discovered characteristics could lead to important advances in the development of nanomedicine and laser technology.

An international team of researchers discovered properties “unique and exceptional” in diamonds that were formed about 50,000 years ago in the southern US desert as a result of extreme conditions resulting from an asteroid collision.

In your research, published recently In the journal Proceedings of the National Academy of Sciences, academics used state-of-the-art crystallographic and spectroscopic study techniques to analyze the properties of lonsdaleite, a mineral detected in the Cañón Diablo iron meteorite, found in 1891 in the desert of Arizona.

The results of the analysis revealed that the Lonsdaleite, which was considered to be a pure hexagonal diamond, is actually composed of nanostructured diamonds and diaphytes, a type of intergrowth mineral in which two elements of a crystal grow together.

Furthermore, they were able to identify a series of stacking errors or “errors” in the sequences of the repeating patterns of the layers of atoms. In addition, they showed that the diaphysis structure is responsible for a hitherto unexplained spectroscopic feature.

According to the authors, these characteristics found in the mineral were caused by the intense high-energy shock wave released after the collision asteroid, so they suspect that “the structural units and complexity reported in lonsdaleite samples may occur in a wide range of other carbonaceous materials produced by shock and static compression or by deposition from the vapor phase.”

For his part, Christoph Salzmann, co-author of the research, pointed out that “the discovery has opened the door to new carbon materials with interesting mechanical and electronic properties”. These advances, he pointed out, “can lead to new applications ranging from abrasives and electronics to nanomedicine and laser technology.”
