ALS Work Using Microscopy/Imaging
These techniques use the light-source beam to obtain pictures with fine spatial resolution of the samples under study and are used in diverse research areas such as cell biology, lithography, infrared microscopy, radiology, and x-ray tomography.
Crosslink Density of Superabsorbent Polymers
Researchers from The Dow Chemical Company teamed with academic colleagues to conduct x-ray spectromicroscopy studies of superabsorbent polymers (SAPs), materials with a wide range of applications, including disposable baby diapers. Dow has been able to use the results to help develop the process technology for a new SAP-manufacturing plant. Read more »
