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