Projects and Programs

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing

Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

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

Measuring Intermolecular Interactions with Electro-Acoustic Spectroscopy

Ongoing

We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations

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
