Scientists have found a way to create diamonds from oil



Scientists from Stanford University (USA) have successfully tested a new method for producing synthetic diamonds, which promises a multiple reduction in the cost of this extremely useful material. They initially set the goal of creating a “clean system” where the starting material is converted to diamond without the use of catalysts or complex processing processes. And they succeeded, but they had to sacrifice the scale of the process - the volume of synthesized diamonds has not yet drawn even to the concept of “symbolic”.

The subject of attention of scientists was waste from reservoirs with crude oil, dried hydrocarbon films. It turned out that at the atomic level there are many blocks of several cells among them, in which the structure of the atomic lattice is identical to that which forms diamond crystals. But these blocks are tiny and scattered, this is garbage, not material. In addition, they are “dirty” with hydrogen, which weakens the bonds, depriving them of strength.

Physicists at Stanford called these formations “diamondoids,” after which they began to place them on a diamond anvil and irradiate under high pressure with a laser. Minimum energy was spent, diamondoids were heated to only 627 ° C, but this was enough to remove hydrogen from them. Carbon atoms formed new bonds and turned into a full-fledged diamond - true, very, very tiny.



There is no benefit from such "diamond spots" as they ironically called at the university, but the technology itself has great potential. Many industries do not need large synthetic diamonds themselves, but components made from them, such as protective coatings or spot blotches. And such products, very small, but possessing all the properties of real diamonds, as well as cheap to manufacture, can become a serious catalyst for our technological progress.
