Fleeting fluctuations in superconductivity disappear close to transition temperature

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists at Johns Hopkins University and Brookhaven National Laboratory have measured fluctuations in superconductivity that disappear 10-15 Kelvin (K) above the transition temperature. The findings suggest that the transition to the non-superconducting state is driven by a loss of coherence among electron pairs.

Structural distortions emerge from nothing at the nanoscale

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists have discovered that a class of materials known to convert heat to electricity and vice versa behaves quite unexpectedly at the nanoscale. The discovery -- a new "opposite-direction" phase transition that helps explain the strong thermoelectric response of these materials -- may help scientists identify other useful thermoelectrics, and could further their application in capturing energy lost as heat, for example, in automotive and factory exhaust.

New highly stable fuel-cell catalyst gets strength from its nano core

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists at Brookhaven National Laboratory have developed a new electrocatalyst that uses a single layer of platinum and minimizes its wear and tear while maintaining high levels of reactivity during tests that mimic stop-and-go driving. The research may greatly enhance the practicality of fuel-cell vehicles and may also be applicable for improving the performance of other metallic catalysts.
