Diamonds can be made from oil — geologists
Oil diamonds were created by geologists from Stanford University. This requires the right balance of substance content, temperature and pressure.
With a certain adjustment of the physical parameters, it is possible to produce pure diamonds from hydrogen and carbon molecules found in crude oil and natural gas. Moreover, this procedure is performed without the use of catalysts, says in a new study by Stanford University and the National Accelerator Laboratory SLAC
Typically, diamond synthesis requires a large amount of energy, time, and the addition of catalysts. Very often a metal is required that reduces the quality of the final product.
For the synthesis of diamonds, scientists needed three groups of powder that were extracted from the surface of oil tankers. They were loaded into a small pressure chamber, called a cell with a diamond anvil. Then the scientists heated the samples using a laser and examined the result.
It was found that a three-component powder, called triamantane, can be reformed into a diamond with surprisingly low energy.
“Using these building “blocks” you can quickly and easily produce diamonds, and you can also learn more about this process than if you simply simulated the high pressure and high temperature found in that part of the Earth where the diamond is formed naturally”, — say the researchers.
Earlier, scientists from the University of Technology of Sydney in Australia discovered a new method diamond deformation. Using an electric field on diamond nano-needles with a length of only 20 nm, they bent diamonds 90° without destruction.
