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 ealaitil@mtu.edu.
  • For Electron Optics Facility questions or sample preparation, please contact Dr. Erico Freitas at 906-299-2714 or email efragafr@mtu.edu, or Isabella Jaszczak at 734-250-1624 or email imwakeha@mtu.edu
  • For Scanning Probe Microscopy (AFM) & Surface Analysis (XPS) Facilities questions, please reach out to Dr. Timothy Leftwich at tleftwi@mtu.edu.
  • For Confocal Imaging Facility questions, please contact Dr. Marina Tanasova at 906-487-1163 or email mtanasov@mtu.edu (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.

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.

Training:

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.

Best,
Liz
