Erico Freitas Seminar September 29, 2022

Erico Freitas

Department of Biological Sciences Seminar Series

Dr. Erico Freitas

Research Scientist
Materials Science and Engineering
Michigan Technological University

Abstract

Dr. Freitas manages the FEI 200kV Titan Themis STEM in the Electron Optics Facility of the Applied Chemical and Morphological Analysis Laboratory (ACMAL) at Michigan Tech. Transmission electron microscopy (TEM) is widely used for morphological studies of biological systems as it offers a much higher spatial resolution (over 200 times) than optical microscopy. During this seminar Dr. Freitas will present the capabilities of the Scanning transmission electron microscope laboratory at MTU and will address the types of ex-situ and in-situ analysis that can be conducted for biological systems using a diversity of approaches available through the ACMAL.

EBSD Detector Down

The ESEM and EDS system are fully functional. However, the EBSD detector is down until further notice. 

I’ve tried solving the problem with Oxford remotely. Unfortunately, we will need to bring a technician on site and will likely need to replace the HKL box. I am looking into the details and will let you know when I have more information.
