Ames Laboratory has developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields, by placing a tunnel diode resonator, an instrument that makes precise radio-frequency measurements of magnetic properties, in a dilution refrigerator, a cryogenic device that is able to cool samples down to milli-Kelvin temperature range.

Energy Secretary Rick Perry visited Ames Laboratory on Oct. 16, including a stop at the Sensitive Instrument Facility. Here Ames Laboratory scientist Lin Zhou explains characterization techniques using the aberration-corrected scanning transmission electron microscope to Secretary Perry.

Ames Laboratory Science Undergraduate Laboratory Internship (SULI) program student Katrina Fauser, who worked with mentor Tanya Prozorov, explains her research project to Ames Laboratory scientist Emily Smith during the session's closing poster session on Aug. 1.

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with DOE’s Ames Laboratory, have reported an important and unexpected reaction mechanism — called “redox behavior” — on the surface of catalyst support materials that have application in the chemical industry.
