Poseidon Electrochemistry Workshop in Manchester

On the 20th of February Protochips’ Nynke Krans (applications) and Simon Ma (VP of Sales) visited our users in Manchester to demonstrate the operation of the Poseidon system in a Titan TFS microscope. PhD students and Postdocs from Manchester, Cambridge and UCL London came to learn from our applications specialists. We hosted a morning of great talks from both Xiangli Zhong and Simon Ma.

Xiangli Zhong gave a presentation based around the methodologies which have been developed to facilitate the preparation of electron-transparent samples from conventional bulk metals and alloys for in situ liquid/gaseous cell S/TEM experiments.She showed the development of hybrid electrochemical - Focused Ion Beam (FIB) sample preparation methods and redeposition approaches enabling successful insitu analysis using the Fusion AX and Poseidon AX systems.

Simon Ma gave an overview of how Protochips tries to fill in the gaps to in situ electron microscopy using a workflow solution. He talked about how the system can be used for a number of applications and gave examples from published battery, corrosion and electrochemistry studies.

The afternoon session included a tour of the labs and a live demonstration of the electrochemical formation of silver dendrites from a AgNO3 solution. In this experiment, we used cyclic voltammetry to grow and dissolve the silver while imaging at the microscope! Then, we went to enjoy some drinks and snacks with poster presentations and some handson experience with the system.

Thank you again Matthew Lindley and Sarah Haigh for hosting us at your institute!
