Whether you are studying nanomaterial changes, batteries or electrocatalysts, Protochips uniquely supports your research with the Poseidon AX in situ TEM solution. Poseidon AX is not just an in situ TEM holder, but an entire workflow. From sample preparation to data publication, Triton AX fosters relevant results that complement bulk scale analyses and drive research and innovation forward.
- Preparation: During sample preparation, choice in MEMS sample substrates is key to fit the in situ cell to your specific experiment. This is why the Poseidon AX system comes with the largest E-chip choices on the market! With > 300 combinations possible, it is easy to tailor the liquid layer thickness, working electrode (WE) configuration and even change from Pt WE to a glassy carbon WE for optimal resolution.
- Collection: Once the Poseidon AX is fully set up and TEM-ready, the liquid flow can be initiated and electrocatalysis experiments can be performed. All metadata from the biasing is automatically integrated into the experimental timeline using our machine-vision software, AXON Synchronicity. AXON provides live physical and digital correction as well as metadata indexing and integration.
- Analysis: In additional to observing nanoscale reactions in real time, quantification of your material is also incredibly important, which is why the Poseidon AX TEM holder is designed to give the highest Energy Dispersive Spectroscopy (EDS) signal, with optimized x-ray collection and tilt options to fit your microscope. Additionally, EELS and even 4D-STEM experiments can be performed with the Triton AX!
- Publishing: With >250 publications using our liquid phase systems, there is plenty literature to dig through to give new ideas about experiments. If you have questions or need more information, our Success Community has answers and are team is available 24/7 due to our world-wide applications.
Easy-to-follow workflows streamline preparation and analysis, enabling you to scale your electrocatalyst experiment to the nanoscale, while doing this productively and reproducibly and being able to share and filter data easily using the FAIR principle methods.
In this example you can see operando electrochemical 4D-STEM images, in liquid, of copper nanowires. 4D-STEM can be used as an analysis technique to understand the different crystallographic domains in nanomaterials. This technique helps increase understanding in the deactivation process of electrochemistry materials, especially since it is combined with liquid phase studies!
