The U.S. Department of Energy (DOE) has released Ames Laboratory’s Performance Evaluation Report Card for FY 2019, and the Laboratory received its highest ratings ever, and continues for the third year in a row to exceed expectations in a majority of the key performance areas measured.
Visiting Faculty Program Research Projects
CMI research based at Idaho National Laboratory investigates unique materials that don’t behave like normal solids, liquids or gases and could displace toxic chemicals used in metal production processes.
By mixing precipitated nanoparticles (NP) with boron nitride (BN) a 9-fold improvement in DNP NMR sensitivity was realized compared to established DNP protocols. This new protocol enables challenging 2D NMR experiments that reveal the structure and connectivity of atoms in a variety of semiconductor NP systems.
Researchers at the Critical Materials Institute (CMI) and Ames Laboratory are winners of an R&D 100 Award. Researchers invented a magnet recycling process in which magnets are dissolved in water-based solutions, recovering more than 99 percent purity rare earth elements.
An acid-free dissolution rare-earth magnet recycling process has earned a 2018 Notable Technology Development Award from the Federal Laboratories Consortium (FLC).
Researchers at the Critical Materials Institute (CMI) and Ames Laboratory invented a magnet recycling process in which magnets are dissolved in water-based solutions, recovering more than 99 percent purity rare earth elements. Cobalt is also recovered from cobalt-containing magnet wastes. The rare earth materials recovered have been reused in making new magnets, and the recovered cobalt shows promise for use in making battery cathodes.

Above a critical pressure associated with the onset of magnetic order, superconducting and magnetic fluctuations exist over a wide temperature range above their respective bulk transition temperatures. Superconductivity in FeSe under pressure is bulk and competes with magnetism; measurements reveal fluctuations of superconductivity and magnetism likely due to their competing nature similar to other high-Tc superconductors.
A new rare-earth magnet recycling process developed by researchers at the Critical Materials Institute (CMI) dissolves magnets in an acid-free solution and recovers high purity rare earth elements. For shredded magnet-containing electronic wastes, the process does not require pre-processing such as pre-sorting or demagnetization of the electronic waste.
As CMI begins its third phase of operation in 2023, the CMI focus area Crosscutting Research will conduct research around the themes of Enabling Science, Criticality and Supply Chain Analysis,
A new recycling method developed by scientists at the Critical Materials Institute, a U.S. Department of Energy Innovation Hub led by the Ames Laboratory, recovers valuable rare-earth magnetic material from manufacturing waste and creates useful magnets out of it. Efficient waste-recovery methods for rare-earth metals are one way to reduce demand for these limited mined resources.
