S-TEM Provides Insight to Alloy Behavior

S-TEM MappingMaterials Science doctoral candidate Deji Fadayomi, and professors Paul Sanders and Gregory Odegard, are working on these precipitation-strengthening mechanisms in aluminum-based alloys. This atomic-resolution image and elemental maps of precipitates were obtained in aberration-corrected scanning transmission electron microscope (AC-STEM) at Michigan Tech’s Applied Chemical and Morphological Analysis Laboratory (ACMAL) to better understand alloy behavior at an atomic level.

S-TEM Live Lab Tour Video Spring 2018

Michigan Tech faculty and staff presented a live tour of the FEI 200kV Titan Themis S-TEM facility on Facebook last Wednesday, February 14, 2018.

Introducing the tour was Kelley Christensen, science and technology publications writer for University Marketing and Communications. Steve Hackney, a professor in the Department of Materials Science and Engineering, talked about the atomic scale science and engineering taking place in the housing facility, the Advanced Technology Development Complex (ATDC).

ACMAL Director Owen Mills discussed sample preparation procedures. S-TEM specialist Pinaki Mukherjee demonstrated operation of the instrument and its capabilities.

Danielle Langdon is a new lab assistant in the Electron Optics Facility, working under Owen Mills.

My name is Danielle Langdon. I am currently an undergraduate student in Michigan Tech’s Chemistry program. I’ve lived in the Copper Country for half of my life now and graduated from Hancock Central High. While I was in high school I was active JROTC and Drill Team. I am currently finishing my undergraduate degree and will be graduating in the Spring of 2017. After I graduate, I am interested in pursuing a career in Forensics. When I am not in school or working, I enjoy kayaking, rugby, and self-taught programming.
