The Critical Materials Institute, a U.S. Department of Energy Innovation Hub, has fabricated magnets made entirely of domestically sourced and refined rare-earth metals. And that’s important, because rare-earth magnets are used in a wide and ever-increasing number of modern technologies, and the ability to produce them domestically could have broad positive impact on national economy and security.

Scientists can now locate oxygen in the structure of catalysts with a precision of one-trillionth of a meter07/10/2017
A major new application of Dynamic Nuclear Polarization NMR technology at the U.S. Department of Energy’s Ames Laboratory has led to the ability to examine the chemical structure of catalysts with a spatial resolution of less than a picometer, or one-trillionth of a meter. That capability enables scientists to better understand, and design more effective catalysts for the production of fuels and high value chemicals
Ames Laboratory senior physicist Paul Canfield is part of a team of scientists that has found evidence for a new type of electron pairing that may broaden the search for new high-temperature superconductors. The findings, described in the journal Science, provide the basis for a unifying description of how radically different “parent” materials—insulating copper-based compounds and metallic iron-based compounds—can develop the ability to carry electrical current with no resistance at strikingly high temperatures.
Ames Lab scientists’ surprising discovery: making ferromagnets stronger by adding non-magnetic element06/23/2017
Researchers at the U.S. Department of Energy’s Ames Laboratory discovered that they could functionalize magnetic materials through a thoroughly unlikely method, by adding amounts of the virtually non-magnetic element scandium to a gadolinium-germanium alloy. It was so unlikely they called it a “counterintuitive experimental finding” in their published work on the research.
