ATTN – STEM users – TEM sample holder

We recently have encountered issues with the TEM single tilt holder and want to draw your attention to the right way of handling it.

Now that we have several certified users, and the number of users are increasing, and taking into account those parts are very expensive and may take time to replace, we all need to refresh ourselves on how to use it.

Please take a few minutes of your time to watch this YouTube video I find useful.

ACMAL is pleased to welcome Isabella Jaszczak as new Research Engineer to our team.

Isabella graduated with a master’s degree in Material Science and Engineering (MSE) from Michigan Tech in 2023. Her research utilized EBSD and STEM imaging to quantify microstructural changes in high-strength, low-alloy steels. Shortly after earning her graduate degree, she was hired as a research engineer for the MSE department, specifically working with the Institute of Materials Processing, the ARC Research Group, and ACMAL’s electron microscopy facility. She is here to help you with sample preparation, SEM analysis, STEM imaging, or instrument training.

Outside of work, Isabella is a HuskyFit instructor at the SDC and enjoys creating pottery as a member of the Copper Country Community Arts Center’s Clay Co-op. McClain State Park is her favorite place to be in the Copper Country

ACMAL is please to extend an invitation to the MTU research community for a Brunch and Learn session with ThermoFisher on April 25, 2024, 9–11 a.m.

Learn how X-ray Photoelectron Spectroscopy (XPS) can be used to investigate cutting-edge materials via surface chemistry and the elemental as well as electronic state of atoms.

Why you should attend:

  • Expand your understanding of XPS for materials analysis.
  • Speak directly with experts about today’s instrumentation and how it can work for you.

Date: April 25
Time: 9–11 a.m.
Location: M&M 610

Apreo 2 Update

I’m pleased to update you on the progress of the Apreo2 installation. Currently, the installation is proceeding smoothly, with the cryo system scheduled for installation next week, followed by the EDS and EBSD systems. Our aim is to have the instrument fully operational for ACMAL staff operation by April. At that time we will be available to perform staff assisted analysis on the instrument. Subsequently, once our staff is proficient and training protocols are established, we will commence user training, likely by mid-June.

If you have a strong interest in utilizing cryo capabilities for your research projects, I encourage you to reach out to me. Additionally, the Apreo2 will have a GIS and heating stages. If you’re interested in utilizing these capabilities for analysis, our staff will be available to assist you.

Impact on the ESEM Capabilities:

It’s important to note that the installation of the EDS and EBSD systems on the Apreo2 will impact the capabilities of the ESEM. Specifically, while the ESEM will retain EDS functionality, the AzTEC Feature will be discontinued, and EBSD capability will no longer be available on the ESEM. However, both these functionalities will be accessible on the Apreo2.


There have been many questions about training. We will prioritize training for the PIs of the proposal, those requiring EBSD or AzTEC features, and then individuals with prior SEM experience.

Timeline Summary:

  • Cryo system installation: Next week
  • EDS and EBSD system installation: Following cryo system installation
  • Apreo2 operational by ACMAL staff : April
  • Commencement of user training: Mid-June

If you have any questions or concerns please let me know.
