UPR-NSF Earth X-ray Analysis Center
The UPR-NSF Earth X-ray Analysis Center (EXACt) was established under the NSF-MRCe program and is supported by the University of Puerto Rico at Mayagüez under the aegis of the Department of Geology. It contains state-of the art instruments for the chemical analyses of solids and elucidation of their structure, and the imaging of surface textures of solid material.
