That article that made the global Nature cover, withdrawn!

Text ｜ Wang Fang

In 2020, Ranga Dias, a physicist at the University of Rochester, and colleagues published a sensational cover article in "Nature".

They claim that a room temperature superconductor has been found -this material can achieve superconducting under high -pressure conditions close to room temperature.

Although it is only forging carbon, sulfur and hydrogen particles forged under extreme pressure, people hope that one day this material will produce various variants, providing non -destructive loss of nuclear magnetic resonance imaging instruments, magnetic suspended railways, atomic accelerators, and nuclear fusion reactors, etc. Power grid and cheap magnetic.

However, this hope is shattered. According to "Science", "Nature" withdrew the research papers on September 26, and said that the data issues proposed by other scientists in the past two years have weakened the two key signs of the two key signs of the Dias team. Trust.

James Hamlin, an experimental physicist at the University of Florida, said: "For a period of time, people have a lot of questions about the relevant results." Jorge Hirsch, theoretical physicist of the University of California, San Diego, who has long criticized the study, said that it is not enough to withdraw the dissertation. He believes that this covers the evidence of scientific dislocation.

"I think this is a real problem." Hirsch said, "You can't just happen, say‘ Oh, this is different opinions ’.

This withdrawal was extraordinary, because the editor of Nature made this decision regardless of the opposition of all nine authors of this paper.

Dias said: "We adhere to our own work, it has passed experiments and theoretical verification." Senior collaborator, Ashkan Salamat, physicist at the University of Nevada, said that he was confused and disappointed with the decision of the Editorial Committee of Nature.

In 2015, Mikhail Eremets, an experimental physicist in Max Planck Institute of Chemistry, Germany and colleagues reported the first hydrogen and sulfur mixture. Some theoretical physicists believe that adding a third element to the mixture will bring a new variable that can be close to environmental pressure or room temperature.

In 2020, Dias and colleagues added carbon, crushed the mixture in the Vajrayana Avil, and heated it with laser to produce a new substance. They announced in "Nature" to achieve superconducting the bichalium hydrogen sulfur hydrogen system under the conditions of 267GPa and 287K (nearly 15 ° C), but was quickly questioned.

In response to some criticism, Dias and Salamat published a paper on the pre -printing server Arxiv in 2021, which contains some original sensitive data. "It raised questions more than answering." Brad Ramshaw, a quantum materialist at Cornell University, said, "From the process of original data to the release of the data, it is very opaque."

"I think (some public data provided by Dias and Salamat) are fabricated," Hirsch said. He also pointed out that it was suspiciously similar to the data in the 2009 Paper in the Physics Review Express. The study was the same as one of the authors of the "Nature" thesis, but due to the inaccurate magnetization data data, it was withdrawn last year.

EREMETS believes that the Dias team is unwilling to disclose more research details and says that I have tried at least 6 experiments, but they all failed. Salamat said that they were welcome to observe their laboratory, "We are open."

Dias said the team plans to submit the paper to "Nature" without any background deletion. At the same time, they did not slow down, Dias and Salamat jointly created a company that developed commercial room temperature super conductors.

"We are on the cliffs of the new era of high temperature superconducting." Salamat said.
