X-Ray Computed Microtomography

Ongoing
Impact XCT gives information that cannot be obtained any other way from opaque materials and objects. It gives us an “eye inside” so that features, of a certain size range, can be seen. The Division’s XCT instruments can reconstruct 3D images with a voxel size down to about 0.5 micrometers, at the

X-ray computed tomography (CT) for medical applications

Completed
As scale lengths get smaller, diffraction becomes increasingly prominent in tomography. The work here develops diffraction tomography for laboratory sources. A new laboratory scale instrument at NIST/Boulder is dedicated to tomography of integrated circuit interconnects. Tomography software written
Catalyst Testbed

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing
Interested in collaborating? See below What does this project do for industry? Current measurement techniques are unable to follow the reaction pathways during catalysis and are limited to observing only the end products or looking at catalysts outside of realistic reaction conditions. Our new

Zeno

Ongoing
The Zeno software tool computes material, solution, and suspension properties for a specified particle shape or molecular structure using path-integral and Monte Carlo methods. The software was originally developed in Fortran77 at the Stevens Institute of Technology with support from NIST MML. ITL

µMAG: Micromagnetic Modeling Activity Group

Ongoing
µMAG advances the state of the art in micromagnetic modeling by establishing and maintaining communications among interested researchers, by defining a collection of standard micromagnetic problems, and by leading the development of a public reference implementation of micromagnetic software.
