The reservation calendars for the AFM and FIB will no longer be merged. We’re splitting these two calendars. It’s important to note that this is a shared space, and both instruments might be in use simultaneously. If your research is highly sensitive, please make sure to book the room on both calendars.
The new calendars will be named:
Let me know if you have any questions,
The 6th floor computer lab will be closed for the rest of today and tomorrow until 1 p.m. We will be conducting a site survey, so please do not enter the lab.
The FESEM EDS system has been repaired and is available for use.
My apologies for the delay in repairing this detector. The original manufacturer has gone out of business so we have to work with a third party company which has limited availability.
The ESEM is functioning well. However, the instrument is not connecting to the internet. IT is aware of the problem and working to resolve it.
This is a great and useful chart from TedPella (https://www.tedpella.com/) if you want to find out what type of TEM grid works best for your TEM work.
Most of the listed types of substrates are available for ACMAL-STEM users.

This issue is resolved. If you have any trouble with the ESEM please let me know.
Due to alignment issues with the beam on the esem we are not able to get high enough counts for EDS. Please take this into consideration while planning your usage. I am working with SEMTech to resolve this issue.
The ESEM is back online.
Just letting you know I put the TEM grids back in my office (MM622).
If are in need of TEM grids let me know.
Those are the ones we currently have available:

1 p.m. in ChemSci 102, Zoom available.

Session 1 Corrosion: 11:15 a.m.–12 p.m.
Corrosion is a $2.6 trillion dollar problem that accounts for 3.4% of the global GDP, therefore it is well understood that testing and developing better materials to increase the durability of infrastructure such as bridges and ships could save $375-$875 billion annually. To develop resistant materials and corrosion-effective mitigation strategies, a deeper understanding of materials used, and the corrosion processes must first be elucidated.
Using the in-situ TEM systems from Protochips such as the Atmosphere AX (gas cell) and Poseidon AX (liquid cell), researchers can directly observe corrosion processes such as initiation and progression at the nanoscale in real time and under relevant conditions. By introducing corrosive environments while simultaneously monitoring material responses, valuable insights into the kinetics of corrosion reactions can be observed at the nanoscale.
Session 2 Catalysis: 12:15–1 p.m.
To combat climate change and the release of harmful chemicals in the environment, highly efficient catalysts must be developed. Using Atmosphere AX, the in-situ gas cell system from Protochips, researchers can investigate the morphology and atomic structure of catalyst materials, including nanoparticles, nanowires, and other nanostructures to develop more stable and sustainable catalytic systems. Moreover, in-situ TEM allows researchers to perform nanostructure characterization of catalyst-substrate interactions at high spatial resolutions to better understand catalytic processes including formation and evolution of reaction intermediates, surface restructuring, and catalyst deactivation in real time and under relevant catalytic conditions.
Register to attend once per session.

I’m pleased to report that the ESEM repairs will be completed today and the instrument is available as soon as tomorrow morning.

Unfortunately, the power supply did not fix this issue. I’ve done as much remote troubleshooting as possible. We will have a service technician on campus next week to look into the issue.
If anyone has any urgent samples, please contact me and we can make other arrangements.

Just a quick update. It looks like the filament is not the issue. I have been working with SEMTech to diagnose the problem. They are overnighting me a power supply. We are going to replace it tomorrow. I will have an update at that point.
I know many of you are eager to get back on the instrument. I thank you for your patience.

The ESEM is down due to an issue with the filament. We are working on this and hope to have the issue resolved by tomorrow.
