Using a process of only a few minutes, the scientists created rare diamonds at room temperature

Under great pressure and at the right temperature, carbon crystallization produces diamonds in the ground. We cannot wait patiently for billions of years, but also understand how cruel living and working conditions at the mine (diamonds in particular, mining in general) are so cruel, so scientists seek to make needles. artificial erection in a laboratory.

Recently, a group of international researchers have successfully created diamonds in just a few minutes, and have shown that the process is not only very fast but can also take place at room temperature. But do not be happy to send this message to your loved one, these diamonds are not intended to beautify the hands of a girl who is about to get married.

Xingshuo Huang, one of the researchers writing scientific reports, holds a device that makes artificial diamonds in his hand.

Rigid artificial diamonds will be used to cut other super hard materials or as a coating for devices that need a strong protective casing. Artificial diamond is getting more and more popular, science can create it in many ways. Recently, a team of researchers have developed a way to turn fossil fuel molecules into pure diamonds, or in some cases use super-speed lasers to create diamonds from carbon fiber.

The latest breakthrough is made by scientists from Australian National University and RMIT University. They used diamond anvils – tools that can create enormous pressure using two diamond components to squeeze the matter in between – to create diamonds. Under the pressure equivalent to a million-ton ballet dancer standing on top of a shoe, the carbon atoms reacted strangely.

The way we use pressure is at the heart of this story”, Said Professor Jodie Bradby from Australian National University. “At extreme pressure, we force the carbon to go through ‘shear’ – like a torque or shear force. We let this action put the carbon atoms in the right place so that the carbon crystallized into the Lonsdaleite form and the ordinary diamond“.

Conventional diamonds are still found on engagement rings or necklaces, while the rarer Lonsdaleite diamond, which occurs only in the Earth-impact meteorite zones. Using advanced electron microscopy technology, they were able to scan the diamond pattern structure and detect carbon atoms stretched down the stream, like a river of diamonds flowing at an atomic scale.

The photos we took show that normal diamonds only form in the middle of these Lonsdaleite vessels when the new method is applied.“, Professor Dougal McCulloch from RMIT said. “Seeing the ‘rivers’ Lonsdaleite and diamonds for the first time is truly amazing, helping us understand a lot about how they form.“.

The team wants to mass-produce diamonds using a new method, in addition to providing a way to make Lonsdaleite diamonds – a material that is 58% stronger than diamond. “Lonsdaleite has the potential to cut through super-solid materials”Said researcher Bradby.
