Projects and Programs

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

Autonomous Scanning Droplet Cell

Ongoing

Corrosion impacts a broad spectrum of application areas including infrastructure, transportation, and the military. The annual price tag for corrosion mitigation and remediation is 3.4 % of the US GDP. The team is particularly interested in discovering new metallic glasses (metals without long range

$Autonomous materials metrology diffraction measurement performed at SLAC$

Autonomous Systems for Materials Research and Metrology: Accelerating Discovery and Democratizing Science

Ongoing

Materials scientists often need to search high dimensional spaces for knowledge. For example, a scientist may be interested in learning how a material property (e.g. hardness) changes over many (for example, 10) values of a synthesis or processing parameter (e.g., annealing temperature). Such an

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
