Synchrotron x-ray techniques and the extreme brightness of Advanced Photon Source (APS) x-rays were employed by DuPont ™ scientists using the DuPont-Northwestern-Dow Collaborative Access Team x-ray beamline at the APS at Argonne National Laboratory to characterize the metal oxide contents of candidate substitute catalysts, helping in the development of DuPont™ SUVA®, a reliable, proven, and safe hydrofluorocarbon (HFC) alternative to chlorofluorocarbons (CFCs).
