MC)² is excited to host Dr. Tracy Lovejoy from Nion Co. to present Recent Developments in STEM via Zoom on Thursday, 10/29, at 1:00 p.m. to discuss the application of this technique in our current and future research programs. If you are interested in attending, please contact firstname.lastname@example.org for an invite.
As a response to Covid-19 and the need for social distancing, (MC)2 has explored different methods for remote training and collaboration. In addition to managing private training and service sessions through Zoom since our lab reopening in June, we have also developed a YouTube Live series which is open to anyone to attend, whether direct microscope access is needed or not. Users who are interested in access are able to request training as normal through our lab management system FOM, then we reach out once a livestream is scheduled. We encourage participation in live chat in place of the Q&A that would otherwise take place in-person. Anyone who is not a current lab user but has general microscopy interest may also attend live or watch later on our channel. Some of our past videos include the content below:
TFS Talos F200X TEM & STEM Alignments
TESCAN RISE Basic SEM Training
FEI Helios Basic Operation
UHR SACP on the FEI Helios
Cathodoluminescence on the TESCAN RISE
Lorentz imaging and iDPC on the TFS Talos F200X
We will continue to announce new entries in our remote training series as they become available.
As of June 2020, Dr. Emmanuelle Marquis has retired from her position as center director, with Dr. Alan Taub taking on the next directorship. We would like to thank Dr. Marquis for her innovation and service over the last five years of leadership, as she worked tirelessly to bring in cutting-edge new equipment, upgrade existing instruments, standardize training processes, and expand the range of techniques in the center’s repertoire.
We welcome Dr. Taub, MSE professor and senior technology advisor for LIFT (Lightweight Innovations for Tomorrow), who brings a background in industry research and development to this role. Dr. Taub is also the director of the new Michigan Materials Research Institute, in which (MC)2 looks forward to playing a key part. The institute will become a central point of contact between the university, industry, and federal sponsors to collaborate on interdisciplinary materials science research.
Congratulations to the winners of our latest image contest! Thank you to all who submitted.
Rigel Hanbury, “Faceted Crystallites” (Thermo Fisher Nova 200 Nanolab SEM/FIB)
This is a secondary electron image of outer oxide particles formed on 316L stainless steel exposed to 320ºC hydrogenated water for 72 hours to simulate nuclear reactor core corrosion. These particles derive their crystallographic orientation from the underlying metal yielding common facets among separate particles.
Li-Jen Yu, “Doodle Drawing by an Alloy” (JEOL 2100F TEM)
A recolored STEM (scanning transmission electron microscope) image of dislocation loops and defects in an irradiated Ni-Cr alloy. Excessive point defects such as vacancies and interstitials are created in the alloy after irradiation. Once interstitials accumulate on certain crystallographic planes, dislocation loops can form. These dislocation loops can significantly affect the mechanical properties of the alloy.
Insung Han, “Dried Flowers (Thermo Fisher Helios 650 Nanolab SEM/FIB)
Metastable Al-Mn quasicrystals formed by short-pulse laser irradiation, modified to show the dendrites’ resemblance to blooming flowers.
Ziwen Zhu, “Circulating tumor cell interacting with cancer associated fibroblast derived extracellular matrix” (Thermo Fisher Nova 200 Nanolab SEM/FIB)
This is an organoid model we built for circulating tumor cell. CTC was captured by the extracellular matrix and grown with cancer associated fibroblast together.
The (MC)2 image contest is accepting submissions once again through Monday, May 18. The contest is open to all lab users who are graduate students and post-docs at U-M or other universities. Images must be obtained using an instrument at the center and may (but do not have to be) artistically modified. While we are looking forward to the time we can return to operations and see you all back in the lab, we hope that you will share with us some of your favorite micrographs from this past year of research with us.
Center staff will select one winning image and three runners-up to be framed and displayed in our office area. These and other images will also be featured in the ongoing photo collage in the Building 22 hallway outside the lab space. Once all spots in the collage have been filled, we plan to add an informational plaque.
To enter, click here.
Please upload the highest quality image you can with regard to file size, bit depth, and resolution. Preferred image width is 1024 px or above and in .tif format. You are welcome to submit multiple entries if you would like.
All submissions should include the following:
- A title for the image
- A clear and detailed legend
- A short paragraph describing the scientific context
- Explanation of any artistic modification of the image (if relevant)
Participants grant the center permission to use their images in the future in various forms, such as brochures, educational materials for other users, or featuring on our website or other media.
