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 [...]

Fabrication of Differential Amplifiers Using Inkjet Printing and Single Wall Carbon Nanotubes

Sarvestani R.K., Wright B., Triyasakorn K., Utah Valley University, US

Fabrication of Differential Amplifiers Using Inkjet Printing and Single Wall Carbon Nanotubes Inkjet printing is a non-contact method in which small droplets of conductive material such as silver nanoparticle ink or functional material are deposited [...]

Formation and Modeling of Droplet Ejection for Electrohydrodynamic Inkjet Printing

Choi J., Lee S., Son S.U., Sungkyunkwan University, KR

EHD(Electrohydrodynamic) inkjet printing based on electrospray and EHD discharging for tiny droplet/jet is known to be able to generate higher resolution and higher aspect ratio of patterns than the conventional inkjet printing(Lee, 2014). EHD inkjet [...]

Preparation of charged droplets via electro-hydrodynamic spraying of polyelectrolyte solutions for the removal of floating particles with less than 10 um (PM10)

Lee K-I., Lee K., Lee K-I., Lee K., Kim S., Korea Electronics Technology Institute, KR

Ambient air quality tends to be worse due to the particle pollution in the region where the rapid commercialization is going on. Particulate matter (PM) describes fine inhalable particles with the specific diameter and smaller, [...]
