Additional Friday publication post! ?? Is electron diffraction important in your in situ work? This group developed a fully automated computational tool powered by computer vision algorithms for systematic analysis of diffraction patterns, using the #FusionAX to observe the phase transformation of FeOOH particles during ?? heating to 650 K. ??The group enabled rapid acquisition of diffraction pattern images during in situ experiments, providing a robust dataset for the tool's application. ??? The computational tool processes the full dataset autonomously, identifying critical patterns often missed in traditional subset analyses. ??This method significantly reduces manual labor, accelerates data interpretation, and ensures a comprehensive understanding of phase transformations. By combining the high-throughput capabilities of Fusion AX with advanced computer vision algorithms, this approach unlocks new levels of efficiency and accuracy, paving the way for deeper insights into dynamic materials transformations.

Did you know that you can observe the performance of resistive random-access memory (RRAM) devices in real time at the nanoscale? Understanding the performance of RRAM devices is integral to improve their reliability and functionality. As an example, it is possible to create multiple microstructures, test them individually and then observe their endurance and performance using transmission electron microscopy (TEM). Pretty cool, right? With the Fusion AX system from Protochips, you can bias nanoscale devices while observing fundamental changes to these devices in real time. Here is a sneak peak of how this is possible: ?? Preparation: Sample preparation and deposition are critical but tedious steps in all in-situ TEM experimental workflows. Electronic devices are usually created using focused ion beam preparation, for which Protochips has designed a FIB stub tool and specialized E-chips. This leads to successful, consistent and easy preparation, where thinning of the lamella can be done after attaching to the E-chip. ?? Collection: Once Fusion AX is fully set up and TEM-ready, electrical biasing can be done with the same software as the data collection. Biasing of small devices can trigger movement, therefore Fusion AX comes equipped with machine vision software, AXON Synchronicity, providing live physical and digital correction as well as metadata indexing and integration. ?? Analysis: With Fusion AX’s friction-free tilting in two directions, EELS and EDS data can be collected during and after biasing experiments. With these methods, not only can you observe structural changes, but the chemical changes of electronic devices simultaneously. ?? Publishing: Once all the data has been collected and analyzed, data processing can begin. With AXON Studio, researchers can easily filter, plot, sort, create videos and images and visualize trends after an experiment is completed. Since all metadata is integrated into a single software, data correlation and analysis are tremendously accelerated and easily shared. In this example, the oxidation states of pristine and cycled devices were observed using EELS spectroscopy on Pt/NiO/Nb2O5 x/Pt bilayer RRAM devices. This study offers valuable insights into the optimal structural design for enhanced electrical performance and reveals the switching mechanism of the Pt/NiO/Nb?O??/Pt bilayer RRAM device, paving the way for advancements in multilayer devices for memory applications. https://hubs.li/Q02W05dS0 With this workflow, scaling bulk electronic device experiments to the nanoscale becomes easier, while maintaining the highest level of scientific rigor to publish relevant, reproducible and reliable results.

Tuesday publication post! ?? In this newest publication, the authors have looked at different ion beam milling techniques to make FIB lamella for electrical biasing with the #FusionAX system! ??When it comes to transmission electron microscopy (TEM) sampling, traditional Ga ion beam techniques often introduce damage, lowering the chemical stability of samples, particularly for metal thin films. These authors used a Xe plasma-focused ion beam (PFIB) technology to mill heteroepitaxial Ag/Cu metal films. ?Using Xe PFIB ensures pristine sample integrity without the physical or chemical damage associated with Ga ions. In our studies, Ag/Cu interface structures remained intact, free from elemental mixing and more stable over time—even after air exposure. ?Performing in situ electrical biasing with Fusion AX, the Xe-prepared Cu thin films showcased flawless structural properties, ideal for electromigration studies without unwanted artifacts. ??A great paper, showing a leap forward for high-precision, artifact-free analysis in materials science!

Tuesday publication post! ?? In this newest publication from #NanyangUniversity in Singapore, Shu Fen Tan, Hany Roslie, Teddy Salim, Zengyu Han, Dongshuang Wu,Caihong Liang, LimFong Teo, and Yeng Ming Lam looked at Cu nanoparticle plating on carbon nanotubes using the #PoseidonAX system! ?? In the race to develop more sustainable energy solutions, supported nonprecious metal catalysts like copper (Cu) are emerging as promising alternatives to Pt-based catalysts for electrochemical reactions. To truly optimize their performance, a deep understanding of the deposition mechanisms is crucial. In this study, liquid phase electron microscopy was used to observe the electrodeposition of Cu on carbon nanotubes and graphene derivatives in real-time using in situ liquid cell TEM. ?? By combining real-time imaging, electrochemical measurements, XPS, and finite-element analysis (FEA), the authors uncovered how carbon nanotubes serve as an ideal support material for generating finely dispersed, uniform Cu catalysts under mild electrochemical conditions. These catalysts show strong activity toward nitrate reduction reactions (NO3RRs), supported by DFT calculations. ???Due to the high precision measurements of the Poseidon AX, it was possible to explore how nitrogen doping guides Cu deposition, though with trade-offs in NO3RR activity due to lower conductivity. This approach marks a significant step in reducing the reliance on precious metals while enhancing catalyst durability for energy storage and electrocatalysis applications. ???
