PORTLAND, Ore. A new superconducting material fabricated by a Canadian-German team has been fabricated out of a silicon-hydrogen compound. Instead of super-cooling the material, as is necessary for conventional superconductors, the new material is instead super-compressed. The researchers claim that the new material could sidestep the cooling requirement, thereby enabling superconducting wires that work at room temperature.
"If you put hydrogen compounds under enough pressure, you can get superconductivity," said professor John Tse of the University of Saskatchewan. "These new superconductors can be operated at higher temperatures, perhaps without a refrigerant."
He performed the theoretical work with doctoral candidate Yansun Yao. The experimental confirmation was performed by researcher Mikhail Eremets at the Max Planck Institute in Germany.
The new family of superconductors are based on a hydrogen compound called "silane," which is the silicon analog of methane--combining a single silicon atom with four hydrogen atoms to form a molecular hydride. (Methane is a single carbon atom with four hydrogens).
Researchers have speculated for years that hydrogen under enough pressure would superconduct at room temperature, but have been unable to achieve the necessary conditions (hydrogen is the most difficult element to compress). The Canadian and German researchers attributed their success to adding hydrogen to a compound with silicon that reduced the amount of compression needed to achieve superconductivity.
Tse's team is currently using the Canadian Light Source synchrotron to characterize the high pressure structures of silane and other hydrides as potential superconducting materials for industrial applications as well as a storage mechanism for hydrogen fuel cells.
The research was funded by the National Sciences and Engineering Research Council of Canada, the Canada Research Chairs program, the Canada Foundation for Innovation and the Max Planck Institute.
Do you know for a fact that she and her research team were paid off? I wouldn’t doubt it, knowing big oil(JP Morgan, et al)but do they control china, india? Right there you have 1/3 of the human race in 2 side by side countries. We live high on the hog, energy-wise, their’s is a desperate need for cleaner(and more)energy. And remember, Deborah Chung is a chinese name...
Study cooper pairs in superconductivity, and Quantum Mechanics in general. If you’re smart enough the great AHA moment will arrive, why there is negative resistance in this high pressure laminate. Yes, it’s very real...and WONDERFUL...
“Yes, negative resistance. A wire that generates its own voltage”
WOOHOO! That tiny sucking sound you hear is...like capillary action for Internet pipes!
I want some big motors wound with this, I’m gonna make a perpetual motion machine. Who needs Big Oil?
If an increasing voltage applied to a circuit results in an increasing current, that is positive resistance. If an increasing voltage results in a decreasing current, that is negative resistance. Google “tunnel diode”.
