Biosorption-based REE recovery and Sc extraction from low-grade feedstocks.

The novel technology developed at LLNL is a new, effective means of separating and concentrating Sc from lanthanides and non-REEs in unconventional, waste-derived feedstocks, thereby transforming an essentially valueless solution into valuable Sc concentrates.  The results represent an important advance in the development of an environmentally sustainable alternative to organic solvent-based…

natural protein lanmodulin, LanM (blue) bound to three REE ions (cyan).

LLNL researchers along with collaborators at Pennsylvania State University have found that a newly discovered natural protein named Lanmodulin (LanM) could be a potential candidate for extracting REEs from ore or other sources such as coal ash as well as purifying the REE material.  Through joint research, the scientists found that LanM undergoes a large conformational change in response to…

LLNL researchers have developed the hardware and chemistry to allow additive manufacturing of short carbon fibers in a thermoset polymer matrix which have a high degree of structural alignment over conventional cast or pressed short/chopped carbon fiber polymer composites.

The invention is based on the shear dispersal, alignment and concentration of fiber fraction within a resin…

Redox ion-exchange polymers ("redox-ionites") and membranes possessing cation- and anion- exchange, amphoteric, complex-forming and oxidation-reduction abilities have been developed on the basis of the biocompatible synthetic and chemically modified natural polymers. In addition, developments have been made towards methods of obtaining of water-soluble and spatially cross-linked ionites of…
