French and German scientists say they can make diamonds from PET bottles in the lab

French and German scientists say they can make diamonds from PET bottles in the lab

Opinions expressed by colleagues of entrepreneur They are personal.

During a research paper published in the journal science advance and carried out by the Helmholtz-Zentrum Dresden-Rosendorf (HZDR) Center of the University of Rostock in Germany and the cole Polytechnique in France, concluded that, inside Neptune and Uranus, known as the ice planets, it rained diamonds. occur.

In this study, the two planets were tested separately in a simulation environment, in which a laser was shot at a simple PET plastic film and the results were studied.

According to experiments, the diamond rain is produced by the extremely high temperatures present inside both planets, while it is icy on the outside, apart from the fact that it has a pressure millions of times greater than that of Earth.

The team of scientists determined that these conditions can be simulated with a laser, which hits a sample of a plastic film-like material, which is immediately heated to 6 thousand degrees Celsius.

This action can create a shock wave that has the ability to squeeze out the said material in a thousandth of a second, with a pressure capacity a million times greater than that of the atmosphere.

according to what was mentioned by Dominic CrassoHZDR physicist, earlier these experiments were done with hydrocarbons, but the result was similar only to Neptune and Uranus, because the planets contain large amount of oxygen.

Because of the above, it was determined that it was appropriate to convert to PET, such as that used in bottles, as it contains carbon, hydrogen and oxygen in a balanced manner.

After simulations, they were able to determine that diamonds rained on Neptune and Uranus, but also on other planets in the Solar System.

This experiment opened the door to the development of nanometric diamonds, which can be used as medical contrast agents and reaction accelerators.
