Adsorbent Fiber (IMAGE) DOE/Oak Ridge National Laboratory Caption Oak Ridge National Laboratory researchers developed a fiber to adsorb uranium from seawater. Researchers at Pacific Northwest National Laboratory exposed the fibers to Pseudomonas fluorescens and used the Advanced Photon Source at Argonne National Laboratory to create a 3-D X-ray microtomograph to determine that the fiber structure was not damaged by the organism.
