Medical Leave Notification: April 25th to June 6th

I hope this email finds you well. I wanted to inform you that I will be on medical leave from April 25th through June 6th, 2024.

During this period, if you encounter any issues or have any questions, please reach out to the following contacts:

  • For X-ray Facility questions, please contact Dr. Ed Laitila at 906-369-2041 or email
  • For Electron Optics Facility questions or sample preparation, please contact Dr. Erico Freitas at 906-299-2714 or email, or Isabella Jaszczak at 734-250-1624 or email
  • For Scanning Probe Microscopy (AFM) & Surface Analysis (XPS) Facilities questions, please reach out to Dr. Timothy Leftwich at
  • For Confocal Imaging Facility questions, please contact Dr. Marina Tanasova at 906-487-1163 or email (Cell Culture Lab & Flow Cytometer & Confocal).

In case of an emergency, call public safety by dialing 911.

These individuals, as experts in their respective areas, will be able to assist you promptly. However, please note that for general inquiries or matters not specific to a particular area, it is best to contact me upon my return.

Training and analysis requests can be completed online using our Google form

I have complete confidence in the ACMAL team’s abilities to handle any issues that may arise during my absence. Thank you for your understanding and cooperation. I will be sure to get back to you promptly upon my return on June 6th.

Wishing you all continued success with your research.

Attn: Sputter Coater User

The target on the sputter coater has worn out. A new target has been ordered and is expected within 6-10 business days. The target has temporarily been changed to Iridium.

There are special directions for using the Ir target (see detailed instructions below).

Target density: 22.42
Current: 20mA
Coating thickness: 1-3nm

Your two other options are:

1) We have a Cr target. However, in the past that has resulted in charging.

2) As soon as next week, you can start to schedule time with our staff on the Apreo2. Uncoated samples can be imaged using variable pressure mode. VP mode utilizes a gas in the sample chamber as a charge dissipation and signal amplification method, allowing analysis of a sample without preparation in the form of a conductive coating.

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.

Please ask me if you have any questions.

Welcome Isabella Jaszczak – New Research Engineer at ACMAL

Isabella Wakeham Jaszczak, second from left, was among the recipients of a research project award from the ASM Foundation in 2022.

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
