Shedding light on superconducting disorder

25-Sep-2024 - The importance of disorder in physics is only matched by the difficulty to study it. For example, the remarkable properties of high-temperature superconductors are greatly affected by variations in the chemical composition of the solid. Techniques that enable measurements of such disorder and its ...

X-rays and electrons join forces to map catalytic reactions in real-time

01-Jul-2015 - A new technique pioneered at the U.S. Department of Energy's Brookhaven National Laboratory reveals atomic-scale changes during catalytic reactions in real time and under real operating conditions. A team of scientists used a newly developed reaction chamber to combine x-ray absorption ...

Electron pairs precede high-temperature superconductivity

New method exploring 'energy gap' shows electron pairs exist before superconductivity sets in

07-Nov-2008 - Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high-temperature superconductors. These new imaging methods confirm that ...
