Abstract
This research combines the techniques of EELS and liquid in-situ electron microscopy, optimizing the experimental parameters and data analysis approach. EELS has been successfully used in in-situ microscopy before but there are clear challenges and issues to overcome. [5] A major challenge is the opposing criteria for the two techniques. Most liquid in-situ holders require a SiN membrane to encapsulate the cell where the liquid flows, resulting in a relatively thick sample.
