Stanford scientists turn fossil fuel molecules into new man-made drills

A new study has looked at the mechanisms behind diamond formation and found new ways to produce unique forms of artificial gemstones, which may be significant, not just the vaults of global jewelers,media reported. A new type of man-made diamond developed by scientists at Stanford University offers more insight into this high-pressure production process, starting with molecules found in crude oil and natural gas.

Conventional diamonds form hundreds of miles below the Earth’s surface under extreme lymheat and pressure, making carbon crystallize into valuable gemstones. For decades, scientists have been experimenting with ways to turn materials into synthetic materials, with even De Beers, the world’s largest diamond mining company, involving them. However, these methods often involve a lot of energy and require a catalyst to trigger the transformation. Researchers at Stanford University’s School of Earth, Energy and Environmental Sciences are looking for an easier way.

“We want to see a clean system where a single substance can be converted into pure diamonds without the need for a catalyst,” said Sulgiye Park, lead author of the study. “In making new synthetic diamonds, scientists extracted powder from oil tanks. The team examined the materials through a powerful microscope and observed that the atomic patterns in the powder were the same as the tissues of the atoms that make up the diamond crystals.

Unlike conventional diamonds, these different diamond types are known to consist of pure lycins because they also contain hydrogen. The team then loaded the diamonds into so-called diamond scans, which scientists often use to generate extreme pressure and produce super-hard materials. They then heated the materials with a laser and, through a series of tests and simulations, the team found that tri-cage diamonds could be converted into pure diamonds with minimal energy. The carbon atoms of tri-cage diamonds are rapidly aligned at temperatures of about 1160 degrees F (627 degrees C) and at pressures many times higher than the pressure of the Earth’s atmosphere, and hydrogen disappears from the mixture.

All of this was done in less than a second, and the researchers point out that the technology produces very few diamonds. Its real value lies in the insights it can provide on how to form a diamond.

“Starting with these basic materials, you can make diamonds faster and easier, and you can understand the diamond process in a more complete and thoughtful way than just mimicking the high pressure and high temperatures in the diamond,” the researchers said. “

Improving our understanding of how these synthetic diamonds are formed can have a significant impact on the jewelry industry. Diamond hardness, transparency, chemical stability, thermal conductivity and other unique properties can make them useful to scientists in areas ranging from medicine to biological quantum computing. “If you can make a small number of this pure drill, you can dop it in a controlled way for a specific application,” said Yu Lin, senior author of the study. “

The study was published in the journal Science Advances.
