Rare-earth elements are essential for many electronic, energy and advanced defense technologies.  A research collaboration between LLNL and Pennsylvania State University (Penn State) has generated a portfolio of intellectual property (IP), jointly owned by both organizations, that uses bacterial proteins to pick out critical metal ions.  

LLNL has licensed its interest in the joint IP to advanced biochemistry start-up Alta Resource Technologies for commercialization of the resulting technology to transform mineral separation. Similarly, Penn State is negotiating a license agreement with Alta for its interest in the joint IP.
