Join us for the first seminar of the Spring Semester at 1 p.m. Friday (Jan. 22) via Zoom (passcode 645507).
Pinaki Mukherjee (MSW) will present ” Recent Advances in ACMAL STEM Facility.” This talk presents an overview of state-of-the-art capabilities of the aberration-corrected scanning transmission electron microscope (ac-STEM) at ACMAL, Michigan Tech.
Mukherjee joined Michigan Tech in January of 2018. He obtained his PhD in Materials Engineering from the University of Nebraska-Lincoln. He worked as a post-doctorate researcher at Rutgers University, The State University of New Jersey. He was an affiliate of the National Center for Electron Microscopy, at Lawrence Berkley National Laboratory.
The XPS is operational and is available for use. Please note that the sputter gun, that is used for sputtering and depth profile analysis, is currently not functioning properly and is temporarily unavailable. Email me (at trleftwi@mtu.edu) if you are interested in XPS (or Auger) analysis.

Have a happy holiday!
The sputter coater is back online. I’ve temporarily replaced the Pt/Pd target with Iridium. The Ir target will function just as well as the Pt/Pd, it may even be better for high resolution imaging.
Please let me know if you have any questions.
The ACMAL Logbook system will be down on the afternoon of Sunday 12/13. After hours users, who will be using the instruments during this time, please email me. I will need to know your time and the index you will be using.
The sputter coater needs a new target. I’m working with our supplier and should have a replacement soon. Until then we can coat your samples with carbon. Please contact Aleister Kerr or myself if you need any samples coated.
The FIB repairs are complete. The new tip has been installed and it is ready for use.
