A laser-free ultrafast Lorentz electron microscope has been developed, integrating a microwave-based electron pulser to achieve high spatiotemporal imaging of spin-wave dynamics in a topologically textured thin-film permalloy. @BrookhavenLab nature.com/articles/s4156…

If you want to play with clustering in the 4d stem data I presented at #mm2024, just go here ==> @apofelski/v2o3-4d-stem-cluster-demo" target="_blank" rel="nofollow noopener">marimo.io/p/@apofelski/v…😃#marimo (be patient for the data to load)

@g_varnavides @akshaykagrawal @marimo_io @rowancockett @curvenote any chance to also be done remotely ? :)

Workshop will include live demos of the whole technology stack from data visualization to deploying interactive web interfaces, as-well as amazing guest speakers: @akshaykagrawal from @marimo_io and @rowancockett from @curvenote!

Looking forward to organizing an interactive science communication workshop at the @molecularfndry next month, together with @ColinOphus! Come learn how to intertwine narrative and interactive/reactive code with @MystMarkdown, @marimo_io & @observablehq: usermeeting2024.foundry.lbl.gov/digital-scienc…

Incredible new feature from the @marimo_io superteam! Reactive Python presentations have never been so easy to create and share 🙌 Quick STEM probes example to illustrate: @gvarnavides/stem-probes" target="_blank" rel="nofollow noopener">marimo.io/p/@gvarnavides…

Mariana Palos Sánchez @ImpMaterials made a video about her PhD research on #multiferroic domain walls 🔬⚡️🧲 Mariana grows single crystals & thin films @RoyceImperial labs and then investigates the dynamic domain walls’ local functional properties using c-AFM, MFM and 4D-STEM!

Exploring quantum materials for neuromorphic computing @EfrcQ ! Our study on vanadium oxides reveals strain's crucial role in phase transitions, mimicking brain activity. 🧠 doi.org/10.1103/PhysRe… #QuantumMaterials #NeuromorphicComputing #QMEENC #STEM

@Mingquan_Xu It should be possible with a proper monochromated microscope. Looking at the O-H vibrational response would be indeed a good complement to O-K the edge fine structures approach. I didn't have the opportunity to do so yet 😀.

@APofelski congratulations! Is it possible to complementary with phonon specta in STEM to quantify the H-O bonding vibration?

J’ai trop trop honte que j’ai du mal a respirer carrément Je pense à tout ceux qui ont fait le déplacement à Berlin ces deux semaines ceux a qui nous soutiennent chez eux, en VP n’importe où J’abandonnerai jamais, le club n’abandonnera jamais je laisserai personne de cette équipe à abandonner meme si il y a 0.0002% de chance de passer j’en ai rien à foutre Désolé à tous je sais pas quoi dire d’autre on est dans la boue on est humilié désolé de vous foutre la honte quoi qu’il arrive on réalisera notre rêve

Finally out ;). One lesson, do not use GPA on nanoparticles !! sciencedirect.com/science/articl…

@g_varnavides Thanks for sharing

This year at #MM2023, I tried a new client-side interactive presentation style: gvarnavides.com/2023mm-present… Enough people asked me about how it works I thought I'd write a short walk-through post about it: gvarnavides.com/presentations/

Happy #MicroscopyMonday 🔬 Here is a HAADF-STEM Z-contrast image Milan Heczko captured of M23C6 carbide atomic structure obtained using probe aberration corrected TFS Themis-Z STEM with electron beam parallel with crystallographic zone axis.

Tell me I'm not the only one to see it?
