ACMAL is pleased to welcome Joey Tomei to the ACMAL team as a full-time Research Engineer I.

Joey completed his BS in material science and engineering from MTU in 2023 and is currently completing his MS in material science and engineering. During his graduate studies, he investigated biodegradable magnesium alloys for cardiovascular implants. He worked with SEM, EDS, EBSD, XRD, and TEM to characterize these alloys. He has also worked on the ICON Olympus Off Planet Construction project where he characterized simulated lunar soils using XRD and SEM techniques. His areas of expertise include characterization of anorthite minerals, sample preparation, XRD analysis, and SEM imaging and analysis. When he’s not working, he enjoys exploring the Copper Country on his mountain bike or skis.

Please contact Joey for help with SEM, XRD,or sample preparation.

Fall 2024 Electron Microscopy Workshop at ACMAL, MTU

Published
By

I am delighted to share we had a wonderful Electron Microscopy Workshop at Michigan Technological University, in ACMAL shared core facility. Graduate students, postdocs and staff attended the event this Fall 2024.

Dr. Erico Freitas conducted one-on-one hands-on SEM and STEM sessions utilizing the ThermoFisher Apreo2 Field-Emission SEM and the FEI Titan Themis STEM to help ACMAL user community to get the most of these cutting-edge research instruments.

“Thank you for the opportunities ACMAL is providing. The workshop gave me more expertise in Apreo 2 SEM” (Shebeer A Rahim, Postdoctoral Scholar, Materials Science and Engineering).

“While I didn’t necessarily get the data I was looking for, I learned quite a bit about the process and know how I should move forward if I want to utilize this instrument in the future” (Ben Jewell, PhD candidate – Mechanical Engineering).

“It was interactive and very informative” (Raksha Dubey D., PhD candidate; Physics).

“This is a very useful and inspiring workshop that allows us to explore the interesting features in microscopy and x-ray diffraction from many aspects” (Dr. Peijia Lin, Research Associate, Chemical Engineering)

ACMAL Billing System Update

Published
By

Dear ACMAL Users,

I hope this message finds you well. We wanted to inform you of an upcoming change regarding the billing and usage tracking system for all ACMAL instruments. Starting from July 1st, we will be transitioning to a new system called FOM (Facility Online Management) for managing these aspects.

To access the new FOM system, you can log in online at fom.mtu.edu with your SSO credentials. Please note that to log in, you must be connected to the MTU internet network. Alternatively, you can utilize the Big Edge IP client to access the system from home. Please refer to the user guide below for more information.

FOM Internal User Guide Draft 3

We understand that transitions like this may raise questions or require some adjustments. To assist you with this transition, we will be hosting information sessions June 26th and 27th. These sessions will provide an overview of the new system, address any concerns you may have, and offer guidance on navigating the transition smoothly.

  • Session 1 – Wednesday June 26th, 1-2pm in M&M 610 or via Zoom
  • Session 2 – Thursday June 27th, 11am – noon in M&M 610 or via Zoom

Thank you for your attention to this matter. If you have any immediate questions or concerns, please don’t hesitate to reach out.

Best,

Hitachi FESEM – Maintenance done – good practice

Published
By

Hi FESEM users,

The Hitachi service engineer did the year’s maintenance on the FESEM this past Monday and Tuesday 5/20 and 5/21.

1) He fixed the spring on the stage where we slid the specimen mount in. It was loose and that was causing some vibration. We should not see less jiggling images at higher magnification.

2) He did the full column alignment. From now on, use the software only when you do the alignments. Do not change the physical knobs of the apertures.

3) The beam monitor aperture is set at position 2, and should be kept at 2 !!!

4) If you ever need to change the objective aperture, only use the knob to switch between apertures 1, 3, or 4. Do not use aperture 2.

Objective aperture sizes: 1 > 3 = 2 > 4

Attn.: Objective apertures 2 and 3 have the same size. We exchange them annually when one or the other gets dirty. This year we are using 3.

Remember: Home stage position is: X=Y=Z=12.5 mm, Tilt = 0, Rotation = 0

Please, let me know if you still experience any problems.

Erico Freitas
