Artificial Intelligence for Chemical Manufacturing

Ongoing
The chemical manufacturing design process relies heavily on the recommended values that engineers and researchers usually obtain from handbooks and databases. Those sources often lack easy ways to judge the reliability of information, either in the sense of where the data come from or what the

Chemical Foundations for a Cannabis Breathalyzer

Ongoing
NIST's initial work in cannabis science was a series of measurements of the vapor pressure of two important cannabinoids: delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Our current effort is funded in part by interagency agreements with the National Institute of Justice and by the NIST
