US made the most precious and valuable materials in the world

US scientists have successfully created a metal-hydrogen material that could act as a superconductor or as a rocket fuel in the future.

Scientists at Harvard University in the United States have successfully fabricated hydrogen-based materials in the laboratory, according to the International Business Times. This is a type of electrically conductive hydrogen that was predicted by physicists Eugene Wigner and Hillard Bell Huntington in 1935. They believed that under heavy pressure hydrogen atoms would exhibit metal behavior, electron.

The team compresses a hydrogen sample between two artificial diamonds at a pressure point of 495 Gigapascal (GPa), greater than the pressure in the center of the Earth. Then, the hydrogen molecules turn into metal hydrogen atoms. The study was published in the journal Science on Jan. 26.

"When you look at the first metal sample on Earth, you're looking at things that never existed before , " said study co-author Isaac Silvera.

Silvera says that the metal hydride material is sustainable and remains in the metal form under reduced pressure. This is similar to the way diamonds form graphite in high temperature and pressure conditions, but still exists in the form of diamonds when it decreases temperature and pressure.

Metal hydride acts as a superconductor at room temperature, does not lose energy during transmission. As a result, the material could be used to make high-speed trains, electric cars more efficient. In addition, hydrogen can also be used as a rocket fuel, helping people explore the distant past of the universe.

"It takes a lot of energy to make hydrogen, and if you convert it to a hydrogen molecule, all of that energy is released, making it the most powerful propulsion rocket man has ever created. " Said Silvera.
