RoomTemperature

Just when you thought the hype about room-temperature superconductors was over, it’s not. A Swiss quantum algorithm startup, Terra Quantum, and a research lab at the State University of Campinas (Unicamp) in Brazil claim that they have discovered a form of graphite that superconducts at ambient temperature and pressure. Terra Quantum isn’t a small operation. The company raised $60 million early in 2022 for its quantum-as-a-service platform. But that doesn’t mean you should get your hopes up.…

Nature has retracted a controversial paper claiming the discovery of a superconductor — a material that carries electrical currents with zero resistance — capable of operating at room temperature and relatively low pressure. The text of the retraction notice states that it was requested by eight co-authors. “They have expressed the view as researchers who contributed to the work that the published paper does not accurately reflect the provenance of the investigated materials, the experimental measurements undertaken and…

Scientists in South Korea have begun developing a room-temperature, ambient-pressure superconductor, if new claims are to be believed.

A magical material that could effortlessly conduct electricity at room temperatures would probably transform civilization, reclaiming energy otherwise lost to electrical resistance and opening possibilities for novel technologies. Yet, a claim of such a room-temperature superconductor published in March in the prestigious journal Nature, drew doubts, even suspicion by some that the results had been fabricated. But now, a group of researchers at the University of Illinois Chicago reports that it has verified a critical…

Scientists announced this month a tantalizing advance toward the dream of a material that could effortlessly convey electricity in everyday conditions. Such a breakthrough could transform almost any technology that uses electric energy, opening new possibilities for your phone, magnetically levitating trains and future fusion power plants. Usually, the flow of electricity encounters resistance as it moves through wires, almost like a form of friction, and some energy is lost as heat. A century ago, physicists discovered…

University of Rochester scientists have made a significant breakthrough by developing a superconducting substance that is suitable for practical use at low temperatures and pressures, marking a historic accomplishment.Researchers have not only raised the temperature, but also lowered the pressure required to achieve superconductivity.In a historic achievement, University of Rochester researchers have created a superconducting material at both a temperature and pressure low enough for practical applications.“With this…

Scientists may have devised a way to make a more practical room-temperature superconductor, according to a new paper published this month in Nature. It’s a bold claim, as the quest to create a superconductor that works under more practical conditions has been exceptionally difficult. Many materials can become superconductors, allowing electricity transmittance with no resistance. However, these often require the materials to be cooled to extremely low temperatures. Scientists have been able to make…

In 2020, Ranga Dias, a physicist at the University of Rochester, and his colleagues published a sensational result in Nature, featured on its cover. They claimed to have discovered a room-temperature superconductor: a material in which electric current flows frictionlessly without any need for special cooling systems. Although it was just a speck of carbon, sulfur, and hydrogen forged under extreme pressures, the hope was that someday the material would lead to variants that…

A team of physicists from UNLV’s Nevada Extreme Conditions Lab (NEXCL) used a diamond anvil cell, a research device similar to the one pictured, in their research to lower the pressure needed to observe a material capable of room-temperature superconductivity. Credit: Image courtesy of NEXCLLess than two years ago the science world was shocked by the discovery of a material capable of room-temperature superconductivity. Now, a team of University of Nevada Las Vegas (UNLV) physicists has upped the ante once again by…

To study superconducting materials in their “normal,” non-superconducting state, scientists usually switch off superconductivity by exposing the material to a magnetic field, left. SLAC scientists discovered that turning off superconductivity with a flash of light, right, produces a normal state with very similar fundamental physics that is also unstable and can host brief flashes of room-temperature superconductivity. These results open a new path toward producing room-temperature superconductivity that’s stable enough…
