Atom Probe Tomography Seminar

This technical seminar on Atom Probe Tomography for 3D Atomic-Scale Characterization will be hosted by CAMECA Instruments. Atom Probe Tomography (APT) is the highest special resolution analytical characterization technique with high efficiency single atom detection for quantitative atom scale 3D compositional analysis and elemental mapping of chemical heterogeneities. This talk will cover APT operational theory, an introduction to sample prep and data reconstruction, and an overview of various applications. A commercial cryo-UHV solution for FIB-APT specimen transfer will also be presented which expands the application space for APT to biological materials, hydrogen containing materials, and surfaces prone to rapid oxidation.

Lunch will be provided

A Giant Tool to See the Tiniest Things

The cryo-TEM housed in Duke’s Shared Materials Instrumentation Facility was recently featured in Duke’s Research News. This instrument helps researchers resolve the complex structures of proteins. The cryo-TEM can capture hundreds of thousands of images of these small molecules, and power software is employed to reconstruct the structures in three-dimensions.
