The U.S. Department of Energy (DOE) today announced an investment of $17 million across 14 projects that will accelerate critical materials innovation while promoting safe, sustainable, economic, and efficient solutions to meet current and future supply chain needs. The projects, which span 11 states, are strengthening and streamlining manufacturing for high-impact components and technologies such as hydrogen fuel cells, magnets for high-efficiency motors, high-performance lithium-ion batteries, and high-yield low-defect power electronics.
CMI research in magnets is noted in the Recycling Today article "DOE to invest $17M in critical minerals supply chain"

Scientists at Ames National Laboratory discovered that confinement effects can be sufficient to reduce the effective coordination number of a metal in grafted organometallic complexes. They applied nuclear dipolar coupling measurements to study the temperature-dependent motions of rare earth amidinate complexes grafted to silica support materials. They observed that ligand dynamics could be hindered, and slowed down, in narrow-pore environments.
Ionic liquids have exceptional properties in separations that may benefit the DOE mission in sequestering CO2 or rare earth elements. Understanding their structure provides a means of exploiting them. Previous investigations have focused on the small (~1-nm) domains formed by ionic liquids. We observe two large domains in tetradecyltrihexyl phosphonium chloride that are stable up to 50˚C.
While organic solvent extraction is a commonly employed technique for rare earth element (REE) recovery, it poses challenges associated with a high volatility, toxicity of solvent, and energy consumption. To address these issues, ionic liquids (ILs) have emerged as more environmentally friendly alternatives, offering low volatility and tunable properties to improve recovery processes. Reports have shown that adding extractants improves both the selectivity and affinity for rare earth element (REE) capture. However, the surrounding chemical environment of REEs in these systems remains not well understood.
