Adaptive Peak Fitting for Isotope Analysis via Atom Probe Mass Spectrometry

July 30, 2021
Author(s)
Frederick Meisenkothen, Daniel Samarov, Mark McLean, Irina Kalish, Eric B. Steel
Atom probe tomography (APT) is an emergent characterization technique that has begun to see widespread use within the last 15 years. The technique offers the highest spatial resolution of any mass spectrometry technique for solid-state specimens, as well

Atom Probe Mass Spectrometry of Uranium Isotopic Reference Materials

July 22, 2020
Author(s)
Frederick Meisenkothen, Mark McLean, Irina Kalish, Daniel V. Samarov, Eric B. Steel
Atom probe tomography (APT) has the highest spatial resolution of any mass spectrometry technique, permitting chemically and isotopically resolved images to be recorded at near-atomic length scales. The technique also has a combined ionization efficiency

In-situ Elastic Strain Mapping During Micromechanical Testing Using EBSD

November 14, 2017
Author(s)
Mark McLean, William A. Osborn
Compared to more commonly used strain measurement techniques, EBSD offers improved spatial resolution and measurement sensitivity. Additionally, EBSD can provide the full deformation tensor, whereas other techniques, such as DIC, are limited to only in

Smart Electronic Laboratory Notebooks for the NIST Research Environment

December 2, 2015
Author(s)
Richard S. Gates, Mark McLean, William A. Osborn
Laboratory notebooks have been a staple of scientific research for centuries for organizing and documenting ideas and experiments. Modern laboratories are more and more reliant on electronic data collection and analysis so it seems inevitable that the

Micromechanical Testing of Electroplated Gold Alloy Films using Theta-Like Specimens

July 2, 2015
Author(s)
Mark McLean, William A. Osborn, Oliver Boomhower, Christopher Keimel, Rebecca Kirkpatrick, Frank W. DelRio
Micromechanical testing of electroplated gold alloy films has been conducted using the theta specimen geometry. Specimens were formed by a standard combination of photolithography, electroplating, and deep reactive ion etching. Testing was performed using
