Many of the high-tech tools we use in our everyday lives rely on rare earth w88 casino due to their desirable magnetic, luminescent and electrical properties. With the demand for rare earths at an all-time high, being able to efficiently extract and process them is of high importance to manufacturers.
Enter Chemical & Materials Engineering (CME) Associate Professor David w88 casino, CME Assistant Professor Maryam Raeeszadeh-Sarmazdeh and Chemistry Professor Ana de Bettencourt-Dias.
Led by Cantu, this research team recently received a 0,000 grant from the U.S. Department of Energy to identify extractants that bind to specific rare-earth w88 casino, allowing them to be efficiently separated from one another.
The team, whose expertise combines a wide range of skills such as peptide engineering, spectroscopy, and molecular simulation techniques, is using peptides — strings of amino acids — to bind to specific lanthanide w88 casino (lanthanides comprise 15 of the 17 w88 casino classified as rare-earth).
“Purifying rare earths is challenging because multiple lanthanides are typically found in naturally-occurring ores,” Cantu said. “Current extractants do a poor job separating particular w88 casino from other w88 casino, making lanthanide purification very costly and environmentally unfriendly.”
“Identifying an extractant that binds specific w88 casino would make lanthanide purification less energy- and solvent-intensive, significantly reducing its environmental impact,” Cantu added. “This would mean that all the purification processes of rare earths could be done in the U.S.”
