Reaction Porous Organic Polymers for Uranium Capture Chem

Uranium recovery from seawater is a promising uranium-extraction method that could provide needed resources for low-carbon energy production. However for widescale implementation of uranium recovery issues of cost and scale must be addressed. In this reaction piece Yavuz explores new materials that could help further the implementation of uranium recovery.
