Full Abstract

In-situ electron energy loss spectroscopy (EELS) is of immense value when studying the chemical structure of functional materials at the atomic scale1. This webinar will introduce the types of information you can obtain using in-situ EELS. Practical examples will be shown by reviewing published in-situ EELS work as well as unpublished in-situ EELS videos obtained using the GIF Quantum® K2 IS system from Gatan.

In the second part of this webinar, we will look more closely at the accuracy of the in-situ heating that is required for each of the experiments presented. MEMS-based heating will be specifically discussed, since these holders are now widely used to improve stability at elevated temperatures. We will discuss the technology behind DENSsolutions heating holders as well as methods, including one EELS-based technique, used to confirm the temperature accuracy of the sample.
