Chemical Foundations for a Cannabis Breathalyzer

Founded in 2019, this program was motivated by the rapid decriminalization of recreational and medical cannabis by state governments. This has led to extensive

Vapor Sampling in the Field

We develop and deploy portable vapor sampling instruments to collect detailed chemical information in the field, in sampling situations where the laboratory is

Fluid Phase Nuclear Magnetic Resonance (NMR) Spectroscopy

NMR spectroscopy is routinely used to analyze chemical mixtures in the liquid phase. It is far less common for these techniques to be applied to vapor-phase

Vapor Sampling to Support Public Safety and Forensics

We develop and evaluate dynamic headspace sampling methods to capture and concentrate vapors from single components (solid or liquid) to determine vapor

Advanced Fluid Characterization - Laboratory Information Management System

The Fluid Characterization Group is developing the advanced fluid characterization laboratory information management system (AFC-LIMS) to support several

NIST Tools for Cannabis Laboratory Quality Assurance

NIST has developed an integrated measurement services program for forensic and cannabis testing laboratories to help ensure the quality of routine analysis

Artificial Intelligence for Chemical Manufacturing

NIST uses AI for high-throughput data evaluation, which is critical to the chemical manufacturing enterprise.

Advanced Mechanical Characterization of Mesoscale Materials

We develop methods to evaluate the mechanical behavior of micro- and mesoscale metal alloys to fracture, and Micro Electro Mechanical Systems (MEMS) materials

Strain Tensor Tomography Reconstruction Algorithm

3D Strain Mapping: Transmission Bragg Edge Strain Tensor Tomography (TBESTT)

Imagine an MRI or CT technique that can peer inside structural materials (e.g., steels) and visualize the strain experienced by structures as they support loads

X-Ray Computed Microtomography

Seeing inside a material object, in three dimensions, is often crucial for proper characterization, so that the link between microstructure and properties can
