Hydrogen converted on nano -scale to superconductor

According to Mehr News Agency, the finding confirms the prediction, which was put forward half a century ago by the Nobel -Nobel physicist Ginsburg, and could make a change in hydrogen storage and transportation as a clean energy source.

Sutleite, the concept that was first discovered in helium in year 2, is a state in which the liquid can pass through the thinnest channels without any friction. This phenomenon was later observed in some atomic gases.

In year 2, Dr. Vitaly Ginzburg, the Nobel Prize -winning physic prize winner, put forward the assumption that liquid hydrogen could also be a superconducting. However, so far scientists have not been able to empirically confirm this hypothesis. For the first time, researchers have shown that hydrogen nanomaterial clusters at extremely low temperatures can be converted to superconducting; A quantum condition in which fluid without friction and viscosity flows.

Previously, such behavior was only observed in helium. The study, conducted by an international team from the University of British Columbia (UBC), the RIKEN Institute and the University of Kanazawa (Kanazawa), was published in the journal Science Advances.

“This discovery deepens our understanding of quantum fluids and can inspire new ways to store and transport more efficient hydrogen, as a clean fuel,” says Dr. Takamasa Mummy, a cool molecule expert and senior author of the article.

Unlike helium, it is very difficult to study hydrogen in liquid state because it naturally becomes solid at -5 degrees Celsius. But Dr. Mumuse's research team managed to keep hydrogen clusters in liquid state using helium nanis as an extremely cold chamber. They reduced the ambient temperature by -0.5 degrees Celsius (1.2 Kelvin) and placed hydrogen nanomaterial clusters into these chambers.

How was hydrogen superconducting? To test the supercite, the researchers placed a methane molecule into hydrogen clusters and rotated it with laser pulses. This method acts as a “canary in the coal mine”; That is, if the methane molecule can rotate without any resistance faster, it indicates that the surroundings (hydrogen) have become superconducting.

The results of the experiments showed that when the number of hydrogen molecules in a cluster is between 1 and 2, the methane molecule rotates without resistance. This finding is a definite sign of superconducting hydrogen.

“When we first saw the clear range of methane in a small drop of liquid hydrogen, we were very excited,” said Dr. Hatsuki Ottani, who conducted the study during his PhD student at UBC. This was a strong sign of hydrogen superconducting. Then the theoretical results of our colleagues at the University of Kanazawa were fully compatible with our empirical data. “

Hydrogen is one of the main options of clean fuel because in fuel cells the only by -product is water. But so far, the challenges associated with the production, storage and transportation of this gas have restricted its associated infrastructure.

The discovery of water -free hydrogen flowing current can pave the way for new hydrogen storage and transfer technologies and lead to higher productivity in the renewable energy industry.

This study not only made a 5 -year prediction of reality, but also opened a new window to better understand the quantum phenomena and its practical applications in future technologies.
