Attention: Due to the limited space in our lab rooms this course will be held as hybrid teaching. All meetings, the lectures, exams... will be digital. For each of the 6 participants one day is reserved to work hands on our instruments. The mandatory preliminary meeting will be on 1.10.2020 8:00. I will provide al link for all participants.
In this meeting the time slots for the lab work will be allocated. All mandatory online meetings and the practical work in the lab will be 01.10.2020 – 14.10.2020. The 6 days of presence each for one student will be 05.10 – 12.10.2020, 08:00 – 14:00.

Our Scanning Electron Microscopes (SEM) offer various techniques to investigate samples.
In this course you will have the opportunity to learn the necessary preparation steps and the usage of the SEM in several modes so that you can apply these techniques with your own samples afterwards.
The following techniques will be offered for sample preparation:
Fixation (glutaraldehyde, OsO4), dehydration (Ethanol, Acetone, DMP), drying (critical point, chemical), coating with gold and carbon, cryopreparation.
On the SEM you will use the following modes:
Secondary electron detector in low vacuum and high vacuum, backscatter electron detector in low vacuum and high vacuum, energy dispersive x-ray micro analysis with EDX detector (demo), cryo transfer of deep frozen samples (DEMO)
