Researchers synthesize room temperature superconducting material

Friday, October 16th, 2020

When I heard that a team from the University of Rochester had synthesized a room-temperature superconductor, I was not expecting this footnote:

The carbonaceous sulfur hydride exhibited superconductivity at about 58 degrees Fahrenheit and a pressure of about 39 million psi.

Dias’s lab at Rochester used hydrogen-rich materials that metalize at lower pressures than pure hydrogen, producing picoliters of superconductor in a diamond anvil cell:

First the lab combined yttrium and hydrogen. The resulting yttrium superhydride exhibited superconductivity at what was then a record high temperature of about 12 degrees Fahrenheit and a pressure of about 26 million pounds per square inch.

Next the lab explored covalent hydrogen-rich organic-derived materials.

This work resulted in the carbonaceous sulfur hydride. “This presence of carbon is of tantamount importance here,” the researchers report. Further “compositional tuning” of this combination of elements may be the key to achieving superconductivity at even higher temperatures, they add.

    39 million psi. Is that gauge or absolute?

  2. Gavin Longmuir says:

    One would think University guys would know better than to mention “carbon” in their press release. Try getting a grant after that!

    Every degree-holding woke government/foundation punter knows that “carbon” is evil and causes the global temperature to soar and kills every carbon-free living creature.
