Superconductivity with stripes

By examining the stripe phase-ordering in La1.875Ba0.125CuO4 (LBCO) under high pressure at the U.S. Department of Energy Office of Science’s Advanced Photon Source at Argonne National Laboratory, a team of researchers probed the relationship between stripe ordering and superconductivity.

Simulating deep earthquakes in the laboratory

More than 20 years ago, geologists discovered a high-pressure failure mechanism that they proposed was the long-sought cause of very deep earthquakes occurring at a depth of more than 400 kilometers (or 248 miles). The result was controversial because seismologists could not find a seismic signal in the Earth that could confirm the results. Seismologists have now found the critical evidence.

A 'sponge' path to better catalysts and energy materials

Scientists from Argonne and Oak Ridge national laboratories, Northwestern University, and Hokkaido University have developed a new oxygen “sponge” that can easily absorb or shed oxygen atoms at low temperatures. Materials with these novel characteristics would be useful in devices such as rechargeable batteries, sensors, gas converters, and fuel cells.
