Researchers from the U.S., Russia, and China have bent the rules of classical chemistry and synthesized a "forbidden" compound of cerium and hydrogen -- CeH9 -- which exhibits superconductivity at a relatively low pressure of 1 million atmospheres. Superconductors are materials capable of ...

One day superconductors could revolutionize energy industry. However, for this to be happen, superconductors must be able to transport electricity under room temperature without resistance. Metal hydrides differ from other superconductors by the fact that they do not own this ability only at ...

Superconductors' never-ending flow of electrical current could provide new options for energy storage and superefficient electrical transmission and generation, to name just a few benefits. But the signature zero electrical resistance of superconductors is reached only below a certain critical ...

Scientists’ theory of polaritonically amplified electron lattice interaction reveals new material design possibilities

07-Dec-2018

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice ...

Electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way

10-Aug-2018

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that have a "super" ability to conduct electricity when chilled by liquid nitrogen? A team of scientists set out to answer this question in one ...

A new intriguing property of cuprate superconductors has been identified, says a new study, which shows that in very high magnetic fields, the resistivity of a thin-film lanthanum-based cuprate scales linearly with the field. The findings present a challenge for the theories concerning the normal ...

The struggle to keep drinks cold during the summer is a lesson in classical phase transitions. To study phase transitions, apply heat to a substance and watch how its properties change. Add heat to water and at the so-called "critical point," watch as it transforms into a gas (steam). Remove heat ...

Superconductors contain tiny tornadoes of supercurrent, called vortex filaments, that create resistance when they move. This affects the way superconductors carry a current. But a magnet-controlled "switch" in superconductor configuration provides unprecedented flexibility in managing the ...
