2 #S25MRS talks down, 1 proposal submitted (internally). Time to take an ebike ride around Seattle before my flight!It's so nice here... great choice, MRS.

Check out my 2 talks at #S25MRS this week in Seattle!

@mphendricks.bsky.social, Michael Campos & the rest of Jon Owen's lab were some of the greatest WANDA users of all time. They took LBNL by storm with boxes of distilled solvents and custom precursors. They showed that robots are pointless if the other parts of your workflow are not reproducible.

I can't believe it's been 15 years since this paper came out! We introduced a nanocrystal-synthesizing robot called WANDA to the world! Now robots & ML are all the rage, but WANDA was a pioneer & is still going strong. @deliamilliron.bsky.social @molecularfoundry.lbl.gov pubs.acs.org/doi/full/10....

New article online: Intrinsic optical bistability of photon avalanching nanocrystals. go.nature.com/3DSOmUC

Thinking of submitting a user proposal to the @molecularfoundry.lbl.gov or any other scientific user facility? Here are my Top 10 tips for writing a Foundry proposal (due March 27th!). These #ProTips should be relevant for most user facilities! 🧵

Check out our perspective article in @materialshorizons.rsc.org where we bust common myths about Photon Avalanching Nanoparticles! doi.org/10.1039/D4MH... Learn why photon avalanches are not avalanches of photons and many other fun facts about ANPs. #chemsky 🧪 See 🧵 below for more myths and art.

📢 The Molecular Foundry's Spring 2025 Proposal Call is now open through March 27! 🎉 Get free access to world-class nanoscale science facilities and expert support to advance your research. Don’t miss this opportunity—get the details now! buff.ly/InlHUYU

Check out @berkeleylab.lbl.gov's highlight of our latest work in @naturephotonics.bsky.social! 🧪 #chemsky #physky

Breakfast under blue skies @molecularfoundry.lbl.gov

🚀Thrilled to share our light-twisting materials from semiconductor nanoclusters! Films of CdS magic-sized clusters helically assembled with record g-factors and large homochiral domains. Congrats to Tom, River, Reilly, Haoyang & Frank! www.science.org/doi/10.1126/science.ado7201 #Chiroptics

Just a bump for this starter pack - as always happy to add more folks, just post below anywhere you see me post it and I will add you go.bsky.app/U5wGm7M

Congrats to Ahn Pan for his final paper from his postdoc @molecularfoundry.bsky.social in Nanoscale Horizons @nanoscale-journals.bsky.social Read how inorganic metal sulfide ligands w/ low phonon energies can enhance the PL of upconverting nanoparticles 🧵🧪#chemsky DOI doi.org/10.1039/D4NH...

#ActuallyProud to share our latest work in @naturephotonics.bsky.social demonstrating intrinsic optical stability in photon avalanching nanoparticles! doi.org/10.1038/s415... Read on to learn how these nanoparticles are like Gwyneth Paltrow 👱‍♀️, and how that’s useful for optical computing.

We started 2025 in full force w/ a new @nature.com pub on 1/1/25 using photon avalanching nanoparticles to sense pN-nN forces with infrared light! Work co-led w/ Bruce Cohen @molecularfoundry.bsky.social & Jim Schuck @columbiauniversity.bsky.social 🧵 www.nature.com/articles/s41...

Check out NPMC, a kinetic Monte Carlo package for predicting optical spectra of lanthanide-doped materials like the complex core/shell nanoparticles we synthesize. NPMC is part of RNMC, a kMC implementation for reaction networks reported in @joss-openjournals.bsky.social: doi.org/10.21105/jos... 🧪🧵

New to bluesky but have a lot of new papers to talk about! First up: a quantum dot (QD) solid state lighting pub co-led by Jonathan Owen's group at Columbia: 🧵https://pubs.acs.org/doi/abs/10.1021/acs.jpcc.4c07446

Our work on the optical bistability of avalanching nanoparticles is now out! These tiny crystals are among the most nonlinear nanomaterials reported and exhibit luminescence hysteresis, which is valuable in advancing optical computing and memory. @molecularfoundry.bsky.social #MSCA rdcu.be/d5pT7
