Crosscutting Research

As CMI begins its 13th year of operation in 2025, the CMI focus area Crosscutting Research will conduct research around the themes of Enabling Science, Criticality and Supply Chain Analysis, and Economic, Environmental and Social Analysis.

Environmental impacts and conversion cost of Nd metal production from Na-Nd-F and K-Nd-F feedstocks via calciothermic reduction (excluding NdCl3 cost).

Research Highlight

Comparative LCA and TEA of neodymium metal production from different REMAFS salts

Comparison between predicted and measured EMF of 𝑁𝑑+3+3𝑒−→𝑁𝑑0, 𝑁𝑑+3+𝑒−→𝑁𝑑+2 and 𝑁𝑑+2+2𝑒−→𝑁𝑑0 reactions in various KCl-LiCl-NdCl3 mixtures and temperatures. The shaded area corresponds to a maximum deviation of +/- 5% (10% total) compared to the exact Measured/Predicted matching values (black sloid line), highlighting that all predictions fall well below 15% of experimental values and validating our contribution to the CMI FA4 Year 13 goal.

Research Highlight

Development of a multicomponent thermodynamic database for molten salt processing of rare earths

Hydrogen production by S. mesophilum incubated with different nominal concentrations of Eu (a) or Sm (b). Decreased hydrogen production compared to the no metal control indicates inhibition of normal metabolic activity for the organism.
