Imaging: Characterization of Porous Transport Media for Hydrogen Fuel Cells

Completed
Accurate, in situ characterization of the physical properties of a porous transport layer (PTL) – porosity distribution, liquid saturation as a function of pressure, liquid and gas permeability, thermal conductivity – is critical to improving the understanding, and hence manipulation, of the water

Imaging: Evolution of Neutron Image Detector Spatial Resolution

Completed
Neutron imaging has yielded valuable insight into the water content of fuel cells because minimal changes to a test section are needed. A limit of neutron imaging is the achievable spatial resolution, which is primarily dominated by the detector. Figure 1 shows the evolution of the spatial

Measurements of Point-Defect Chemistry in Complex Oxides

Ongoing
Project Goal: To develop magnetic resonance, x-ray absorption, electron diffraction, and electrical conductivity measurements to better characterize dilute concentrations of point defects in oxide materials and effectively correlate electro-mechanical properties to measured defect chemistry. Oxide

Multiscale structure and dynamics in advanced technological materials

Ongoing
New technologies increasingly harness materials phenomena that operate across many length-scales: e.g., in selective gas adsorption, additive manufacturing, new alloy designs, or advanced concretes. To overcome technology barriers, it is no longer sufficient just to characterize the materials

Renewable Energy and Fuels

Ongoing
Fuel volatility and chemical characterization. We specialize in the Advanced Distillation Curve (ADC) method, developed at NIST, which is a powerful tool for the measurement of distillation curves to characterize complex fluids. We have applied this to simple hydrocarbons, gasolines, diesel fuels

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
