Projects and Programs

NCNR DAC and CCUS efforts

Ongoing
Objectives To advance US competitiveness in Direct Air Capture (DAC) and Carbon Capture, Usage, and Sequestration (CCUS) Use advanced neutron scattering techniques to understand the adsorption process for the most promising materials for adsorption-based carbon capture and provide avenues to

Macromolecular Architectures

Ongoing
This project’s purpose is to synthesize and characterize model thermoplastics, thermoplastic elastomers (TPE), and mixed resins with systematic variation of polymer sequence, chemistry, and architectures to generate libraries of quantitative structure-property relationships validated by multiple
Cannabis

NIST Tools for Cannabis Laboratory Quality Assurance

Ongoing
Since the 1970s, cannabis (marijuana and hemp) and its constituent, Δ 9-tetrahydrocannabinol or THC, have been classified as Schedule I controlled substances. Seized evidence is tested by forensic laboratories, which verify the identity of the plant through macro- and microscopic evaluation and the
Platform for Realizing Integrated Molecule Experiments

Platform for Realizing Integrated Molecule Experiments (PRIME)

Ongoing
Blackbodies realize a clear relationship between radiated power and temperature through Planck’s law. While a reliable instrument for temperature and power calibrations, blackbodies are afflicted with a plethora of systematics (e.g., non-ideal emissivity, propagation loss, temperature gradients
