X-ray computed tomography (CT)

Ongoing
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

Magnetic Sensing and Metrology

Ongoing
Magnetic sensors have a wide range of sensitivities, spatial resolution, dynamic range, bandwidths, size, and cost. Applications such as magnetic data storage and chip NDE require sensitivity of 1 nT, spatial resolution down to a few nanometers and bandwidths up to 10 GHz, while MEG requires

Reflectance Measurements of Human Skin

Ongoing
Investigations of the optical properties of human skin have largely been limited to the visible part of the electromagnetic spectrum, whereas many applications require high-quality reflectance data in the near infrared and short-wave infrared. Further, the complex and dynamic nature of skin results

Cell-based Assay for Mechanistically-based Prediction of Cytoxicity

Ongoing
Ricin is a type 2 ribosome inactivating protein (RIP) belonging to the A-B family of toxins and is of particular interest because of its potential use as a biological weapon and the dearth of rapid and sensitive assays that could assist detection and decontamination. The ricin toxin inhibits protein
