Please remember to close the lab doors at the end of your session. These are very expensive instruments and we want to ensure they don’t get damaged.
I will be out of the office from October 4th through October 9. I will be monitoring emails and responding when I get back.
Below are the contacts if you need assistance with instruments in the Electron Optics Facility or the Scanning Probe Microscopy Facility.

The BSE detector has been repaired. A big thanks to Dr. Ed for resoldering it!
The ESEM can still be used. However, the backscatter detector needs to be repaired. There is a wire that needs to be resoldered. The repairs should be completed by the end of the week.
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.
For additional information, visit the Department of Biological Sciences.

The STEM is available for use. Please limit participants in the room to 2.
The STEM is currently down for repair. The rooftop chiller requires a new power supply. MTU Facilities is working on the project. However, at this time we do not have an estimated completion date. I will send out an update when we know more.
This is just a reminder that the ACMAL facilities will be CLOSED Monday, September 5th, 2022. This is a University Closed Holiday so the building will also be locked. Only those with swipe access will be able to use the instruments. Please plan your instrument use accordingly.
P.S. I will be on vacation September 1st – 5th.

The maintenance on the EBSD is completed. The ESEM is available for use effective immediately.
If you had plans to use the STEM in the August-September I’ll be unavailable on the following dates:
August 1st – 5th (out of town); returning flight schedule for Friday 5th in the morning I’ll be available for online.
August 18th – September 7th (out of town)
