This five-year project grant from the National Science Foundation totals $455,937 and aims to advance understanding of lanthanide-extractant complex solutions across liquid-liquid interfaces. Funded under the NSF Engineering program (CFDA 47.041), the award supports research at the University of Nevada, Reno from July 2021 through June 2026. The project aims to solve the molecular structure of complexes that form between rare earth elements and extractants used to separate lanthanides, providing...
This $289,851 Project Grant award from the National Science Foundation's (NSF) Integrative Activities (IA) program supports research at the University of Delaware that aims to develop new pathways for the recovery and recycling of rare-earth elements (REEs). The project focuses on investigating the formation and properties of high-temperature REE-sulfate liquids, with the goal of advancing alternative REE extraction and separation technologies that could enable more circular manufacturing...
This National Science Foundation (NSF) Small Business Innovation Research (SBIR) Phase I award to Reegen Inc. for $275,000 will support the development of a clean, biological system for extracting and purifying rare earth elements (REEs) from various waste and end-of-life sources. The project aims to reduce the negative environmental impacts of REE production and decrease U.S. dependence on imported REEs, which are critical for manufacturing modern electronics and sustainable energy...
The National Science Foundation (NSF) awarded a $595,476 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to The Johns Hopkins University. The grant will support a 3-year research project to study and develop a new class of immobilization substrates, namely mesoporous protein crystals, for critical element separation. The project aims to obtain a comprehensive understanding of protein crystals as substrates for immobilizing metal-binding proteins (MBPs) to...
The National Science Foundation (NSF) awarded a $180,189 Project Grant under the Geosciences program (CFDA 47.050) to The Washington and Lee University. The grant, effective August 15, 2024, with a projected completion date of July 31, 2027, will support collaborative research to investigate the potential for extracting rare earth elements and yttrium from acid mine drainage using biotic and abiotic hydrous manganese oxides. The research aims to identify optimal conditions for concentrating...
The National Science Foundation (NSF) awarded a $1,000,000 Project Grant under the NSF Engineering program (CFDA 47.041) to Trustees of Tufts College, doing business as Tufts University, for a project titled "RAISE: CET: ZWITTERIONIC MEMBRANES FOR RARE EARTH ELEMENT (REE) SEPARATIONS." The project aims to design novel membrane materials featuring nanoscale structures, inspired by biological pores, that can selectively enrich and separate rare earth elements (REEs). Researchers will use polymer self-assembly to synthesize membranes with tunable nanochannels and functional pore chemistries for selective interactions with REEs. The project will quantify the effect of nanoconfinement on ligand-REE thermodynamics and interrogate REE transport mechanisms through bench-scale experiments and simulations. The project includes sub-awards to the University of Texas at Austin and Case Western Reserve University to support the research activities.
