A Programmable Transmission Electron Detector for Nanomaterials Characterization in a Scanning Electron Microscope

Holm J., Caplins B., Keller R., National Institute of Standards and Technology, US

A new programmable detector for scanning transmission electron microscopy (p-STEM) is described. A digital micromirror array lies at the heart of the detector and serves as a programmable virtual objective aperture. Two sensors, a photomultiplier [...]

Determining Elastic-Plastic Material Properties Using Instrumented Indentation Test and Finite Element Simulation

Promer D.R., Najafabadi Z.S., Kim J., Kujawski D., Western Michigan University, US

A new technique that can determine the elastic-plastic properties of metallic materials using the instrumented indentation test and finite element simulation is developed. This non-destructive technique can be applied to additively manufactured and/or surface treated [...]

Curvature Change Analysis of SMART Fibers used for Temperature Adaptive Insulation

Latulippe A., Ripa C., Sun H., Fossey S., Drew C., University of Massachusetts-Lowell, US

A thermally adaptive insulation has previously been developed by the US Army. The insulation is designed to expand at lower temperatures and shrink at higher temperatures. This is accomplished using multi-component polymer fibers that are [...]

Characterization of Magnesium Silicide Stannide Powder for use in Selective Laser Melting

Gray R., LeBlanc S., The LeBlanc Lab, US

This study examines magnesium silicide stannide (Mg2Si0.4Sn0.6) powder, a thermoelectric material optimal for high temperature applications. Powder morphology and particle size distribution were analyzed through optical microscopy and the image analysis software FIJI. The ability [...]
