Impact of palladium/palladium hydride conversion on electrochemical CO2 reduction via in-situ transmission electron microscopy and diffraction

By

An additional Friday publication update! Congratulations on a great #NatureCommunications from authors @Ahmed Abdellah of the group of @Leyla Soleymani and @Drew Higgins! In this newest publication, they showed how to remarkably do #diffraction at operando level during in situ electrochemistry. They used the #PoseidonAX system to look at Pd-based catalysts for the CO2 conversion … Read More

Direct imaging of electron density with a scanning transmission electron microscope

By

Tuesday publication update! A new pioneering technique, known as secondary electron e-beam-induced current (SEEBIC), offers atomic-scale insights into material properties like conductivity, connectivity, and work function. However, this technique can also be used together with in situ electron microscopy. In this newest work, authors used the #FusionAX system and SEEBIC imaging on a stacked 2D … Read More

Functionalized MXene filmes with substantially improved low voltage actuation

By

Tuesday publication update! Have you ever wanted to see MXenes in the electron microscope in real time using electrochemstry? The authors of this newest publication have looked at Ti3C2Tx MXene Film for High-Performance Actuators using the #PoseidonAX system! The enhancement of tetrabutylammonium (TBA) in MXene catapults the in-plane actuation strain by a staggering 337%, amplifying … Read More

Mapping of the electrostatic potentials in a fully processed led device with nm-scale resolution by in situ off-axis electron holography

By

Additional Friday publication update! In this newest publication, the authors used the electrical capabilities of the #FusionAX system to look at the optoelectronic properties of fully processed red-emitting AlGaInP micro-diode devices ️The quantum wells within the diode exhibited a fascinating behavior—they rested on a potential gradient until reaching the threshold forward bias voltage for light … Read More

In situ TEM studies of relaxation dynamics and crystal nucleation in thin film nanoglasses

By

Tuesday publication update! In this recent publication, the #FusionAX system was used to directly observe crystallization processes at glass-glass interfaces in sputtered CuZr thin film nanoglasses. The authors utilizing in situ heating experiments combined with other interesting techniques such as nanobeam diffraction patterns (NBDP) and electron correlation microscopy (ECM). This powerful combination allowed them to … Read More

Asymmetric nanoparticle oxidation observed in-situ by the evolution of diffraction contrast

By

Tuesday publication update! Are you interested in structural compositional changes during dynamic behaviors? The following article has researched just this! In this latest work in-situ TEM experiments using the #FusionAX system have uncovered the oxidation from wüstite-magnetite (FeO@Fe3O4) core-shell nanoparticles to single crystalline magnetite, Fe3O4 nanoparticles. Using the ‘Ashby-Brown contrast,’ the structural changes of these … Read More

Unraveling and leveraging in situ surface amorphization for enhanced hydrogen evolution reaction in alkaline media

By

An additional Friday publication update! Are you interested in doing hydrogen evolution reactions using in situ liquid cell electron microscopy? In this newest publication in Nature Communications the authors looked at the surface amorphization in alkaline media! In this latest work the authors infused a trace of Ru (0.81 wt.%) into NiPS3 nanosheets, and witnessed … Read More

Carbon nanofiber growth rates on NiCu catalysts: quantitative coupling of macroscopic and nanoscale in situ studies

By

Tuesday publication update! In this newest research written by @TomWelling, the #AtmosphereAX system was used to track carbon nanofiber growth from NiCu-catalyzed methane decomposition under true working conditions. By directly comparing real-time overall carbon growth rates in a reactor (measured gravimetrically) with nanometer-scale carbon growth observations (by electron microscopy), the ex-situ and in-situ results can … Read More

Shedding light on the birth of hybrid perovskites: a correlative study by in situ electron microscopy and synchrotron-based x-ray scattering

By

An additional Friday publication update! Lead halide perovskites (LHPs) are the future of optoelectronic devices, thanks to their unique physical properties. Yet, the synthesis of MAPI perovskites via ligand-assisted reprecipitation (LARP) has so far not been researched. In this groundbreaking study, advanced in-situ techniques were done with the #PoseidonAX and the #Atmosphere system to demystify … Read More
