New Flash Talk! 🔬🎙️ Watch "Insights into Measuring Local Hydrogen Concentration in Pd Nanoparticles via In-Situ Gas TEM" presented by Dr. Svetlana Korneychuk at Karlsruher Institut für Technologie (KIT). #AtmosphereAX was used for detecting hydrogen concentration in metals at the nanoscale. Svetlana and her team measured hydrogen levels in palladium nanoparticles with a resolution as fine as 4 nanometers. The technique tracks changes in the Pd plasmon peak during hydrogen loading and release, revealing how hydrogen distribution, microstructure, and strain interact inside the material, paving the way for advances in hydrogen storage and embrittlement research!

Tuesday publication post! 📖 In this newest publication from #KAIST, authors have looked at the synthesis of Mo interconnects at a sub-10 nm scale using the #PoseidonAX system! As devices shrink to the sub-10 nm scale, creating reliable interconnects becomes increasingly difficult. Using a wet-etching process, the authors were able to achieve a smooth surface instead of a more conventional, but problematic, rough Mo surface! By using the Poseidon AX system, the authors gained insight in the following: 🔬 Direct visualization of how etchant choice influences reaction product buildup 📈 Confirmation of diffusion-limited etching dynamics in real time 💧 Experimental proof that isotropic wet etching yields atomically smoother Mo surfaces Using this specific synthesis method allowed to create a high-quality material, that can potentially be used in next-generation electronic device fabrication!

What if you could see gas generation before going in the TEM? Optimizing electrochemical parameters inside the TEM consumes valuable microscope hours. That’s why we’re excited to introduce our new glass E-chips; designed for ex situ optimization before ever going into the TEM. These chips assemble just like standard electrochemistry E-chips, but the clear glass design makes it possible to directly visualize gas evolution and reactions even at the counter electrode using a standard optical microscope. Available with both glassy carbon and platinum working electrodes, they allow researchers to: Optimize electrolyte concentration, flow rate & applied potential before going into the TEM Use an optical microscope to observe reaction behavior in real time Save time and reduce costs by minimizing trial-and-error inside the TEM These chips are not TEM-imaging compatible — but they are a powerful addition to the electrochemistry workflow, helping researchers streamline experiments, optimize parameters efficiently, and get the most out of their TEM time.

Sometimes TEM images catch our eyes for looking particularly other worldly. It doesn’t take much for our minds to envision something creepy emerging… Like this ghosty zeolyte sample we looked at using AXON Dose 👻, a little gold chloride witch viewed in liquid with Poseidon 🧙🏼♀️, or some Echem skeletons and spirits ☠️! What’s the spookiest looking thing you’ve seen under the microscope? Happy Halloween from Protochips! 🎃 #spookyscience #microscopy #halloween

Tuesday publication update! 📖 In this newest publication focusing on electrocatalysis in the microscope, researchers looked at copper bimetallic catalysts during CO2 electroreduction! Using in situ liquid-phase TEM with #PoseidonAX, researchers Sungin Kim and Jungwon Park uncovered a general principle behind how Cu-based bimetallic catalysts evolve during the electrochemical CO₂ reduction reaction (CO₂RR). What did they see? ✅ Reconstruction occurs through selective dissolution and redeposition ✅ The degree of restructuring depends on the miscibility of Cu with a secondary metal (Ag, Fe, Zn, or Pd) ✅ These changes directly influence product selectivity, shifting the balance between C1 and C2 products like ethylene and ethanol This research shows that catalyst design is not just about the starting material, it is about predicting and controlling how the catalyst will evolve in real electrochemical environments. Using liquid phase microscopy including electrochemistry, it is now possible to observe these reconstructions in action. Want to read the entire work?

John Damiano and Simon Ma had a wonderful time visiting our distributor, Lotis Korea, last month! ✈️ Their meetings gave great insights into the future of microscopy in the region. We look forward to visiting again in the future! #Microscopy #Protochips

Tuesday publication post! 📖 On brand with our nanomaterials synthesis webinar is this newest publication in #NatureMaterials talking about self-assembly of nanoparticles! Mechanical metamaterials gain their unusual properties — from shape morphing to phonon wave manipulation — through geometry and topology. But bringing these principles down to the nanoscale has long been a challenge. Using the #PoseidonAX system, researchers were able to directly image phonon dynamics in self-assembled nanoparticle lattices in real time. In summary: 🔬 Phonon band structures and nanoscale spring constants measured at unprecedented resolution 💠 Critical insights into colloidal interactions beyond nearest neighbors 💧 A bridge between mechanical metamaterials and nanoparticle self-assembly In situ liquid phase electron microscopy makes it possible to observe, model and research the self-assembly of nanomaterials at the nanoscale!

In August Ben Addis visited University of Missouri-Columbia to install a #Poseidon system with heating and electrochemistry, as well as AXON with Dose on their Spectra 300. He said it was a successful visit with a very engaged and positive group! We're looking forward to seeing the results their future experiments bring! Special thanks to Min Su, Director of the EMC, for his flexibility and communication which played a large role in this successful implementation! Pictured in the photo are Ben Addis, Indeewari Karunarathne, Dilan Gamachchi, Ahmed Jasim, PhD, Andrew Meng, JAEWON JAMES LEE, and Moonchul Park.

Last month Yaofeng Guo and Simon Ma had a great time at EM in Wuhan, China! ✈️ The 2025 National Electron Microscopy Annual Conference focused on advances in aberration-corrected transmission electron microscopy and a range of related techniques, including in-situ, high-resolution scanning, scanning probe, cryo-electron, and laser confocal microscopy. It highlighted the applications of these methods across disciplines such as physics, chemistry, life sciences, geoscience, and medicine, as well as emerging fields like new energy, information technology, and advanced materials. #Microscopy #TEM #Protochips
