Scientists create diamonds in lab at room temperature by mimicking asteroid collision

In a very unique creation, a team of scientists produced two s of diamonds in a lab within minutes by using asteroid collision. two s of diamonds include both, regular diamond and Lonsdaleite. Published in Journal Small, findings say that in a rmal diamond, atoms are arranged in a cubic crystalline structure. However, Lonsdaleite is a different of diamond. 

Scientists produce diamonds 

As per research, Lonsdaliete is considered to be 58 per cent harder than usual diamond. Diamonds have been synsised in laboratories since year 1954. It was after this that Tracy Hall at General Electric created m using a process that mimicked natural conditions within Earth’s crust. As a result of this, high-pressure, high-temperature diamonds were created which were similar to those which are found in nature. or method of manufacturing diamond is chemical-gas process which uses a small diamond as a “seed” to grow larger diamonds.

As a part of this research, a small experiment was designed using a small chip of graphite-like carbon. It was n subjected to both extreme forces and high pressure. ditional heating was put to use. Using vanced electron microscopy, sample which came as a result contained both regular diamond and Lonsdaleite. structure was similar to “shear banding” which was observed in or materials. This suggested that shear forces led to formation of se diamonds at room temperature.
