A scalable, safer, and potentially cheaper way to isolate valuable isotopes
New York, NY—July 13, 2023—New research published in Science Advances, led by Yuan Yang, associate professor of materials science at Columbia Engineering, and collaborators at Lamont-Doherty Earth Observatory, demonstrates a novel technique for isolating isotopes.
High Stakes
Oxygen is a critical component in the positron emission tomography (PET) scans oncologists use to search for tumors. But not just any oxygen will work. While most oxygen atoms have eight neutrons, about 1 in 500 atoms has ten. Those extra neutrons are necessary for the PET imaging scans to work.
The Challenge
It’s extremely expensive to isolate ...
