Sandia National Laboratories Large Z machine capable of creating 20 Giga magnetic fields.
A joint research team at Sandia National Laboratories in the United States and the University of Rostral in Germany recently succeeded in squeezing liquid deuterium (deuterium) into metalloid under high pressure, closer to the ultimate goal of generating solid metal hydrogen. The research is published in the latest issue of Science.
Deuterium hydrogen is a stable morphological isotope, the element symbol is generally D or 2H, the nucleus by a proton and a neutron, the content of nature is about 7000 atomic hydrogen, can be used for thermonuclear reaction was Known as "the future of natural fuel." Dating back to 1935, two researchers, Forefront Huntington and Eugene Wigner, for the first time proposed that the theory that metallic hydrogen is available at very high pressures is indeed possible: liquid or solid hydrogen at millions of atmospheres Under high pressure into a conductor, the conductive metal is the characteristic, it is called metal hydrogen. Since then, various research groups have tried to get metal hydrogen samples to prove the theory is correct, but so far, has not been successful. Nevertheless, theorists infer that metal hydrogen is a high temperature superconductor and is a high density, high energy storage material.
According to a recent report by the Physicists Network, researchers used techniques based on extruding samples between two diamond tips, hoping to turn hydrogen-rich compounds into metals. However, due to the problem of over-excitation of the sample material, studies have found that it is not possible to achieve the final result using a double diamond tip.
In this experiment, researchers chose another route to develop a new way to increase stress without causing other problems. They used Sandia National Laboratories to create a large Z machine with a 20 Gigabit magnetic field. For the first time, liquid deuterium samples were pressurized and then vibrated and moved by an Z-machine through an electrode, which in turn hit deuterium in front of the container, A shock wave is caused to pass through the sample, allowing it to be further compressed. After the material is concentrated, the researchers take a common metal identification method to measure the extent to which the sample can reflect light. Test results show that when the sample is condensed, it can be reflected from a transparent state. This clearly shows that liquid deuterium has changed from an insulator to a metal.
