The Johnson group lost a bet and now we are on twitter. We shall see how this goes. . .

This idea was born something like 15 years ago over pizza and nerf basketball in @Andy_P_Ault's office, and finally the technology is there to make it happen. . .

Very excited to start up a new direction in the lab, with the help of the #DiscoveryPrize! We will start building an instrument that can simultaneously measure the size and chemical properties of ultrafine aerosol, one particle at a time.

@SBUArtsSciences @StonyBrookMed We’re so proud to announce that Chris Johnson has won the 2023 #DiscoveryPrize!

Also very grateful to the @AldaCenter for patiently showing me how to make my talk understandable by humans! Their training is always so helpful!

[Johnson PChem Group @cold_trappers]

Thanks to @doescience for supporting this work through an Early Career award!

Happy to announce Hanna's first first-author paper, which came out in @angew_chem: a detailed study of the hydrogen atom in Au9 nanocluster! We had a big assist from Rebecca Gieseking's group at Brandeis on the theory...

Along the way, we stumbled into some direct evidence supporting the hypothesis that H atoms and Au atoms behave very similarly in these nanoclusters, supporting another decades-old gas phase observation.

This was a fun one with @BorosLab! We figured no problem, just gotta find that unique carbonyl in the spectrum. As usual, it ended up being harder than that, but in a way that allowed us to flex our spectroscopy muscles. Isotopes are a vibrational spectroscopist's friend too!

We also note that a significant fraction of this work was done by an excellent undergraduate, Danika Heaney, who was with us remotely in summer 2021 in the @NSF REU program here at @StonyBrookChem - we will be looking for another great student this summer so spread the word!

[Johnson PChem Group @cold_trappers]

Excited to announce our first paper of 2023, out in @J_A_C_S ! We explore the intermolecular interactions holding together clusters of ammonia and iodine oxides, potential aerosol precursors in polar and coastal regions.

[Johnson PChem Group @cold_trappers]

We find that hydrogen bonding, halogen bonding, and even covalent bonding all compete to stabilize these clusters, and that hydrogen bonding with ammonia seems to promote the formation of even larger iodine oxides.

[Moore Foundation @MooreFound]

Eszter Boros’ invention enables the highly selective capture of radioactive metal ions, paving the way for the application of scandium radioisotopes in the non-invasive, early diagnosis and targeted radiotherapy of cancers. https://t.co/QaqRChhrTU #mooreinventors

@barneygrubbs Q: What are we gonna do with all this oil?

A: Olefino!

@e_boros

[Johnson PChem Group @cold_trappers]

New lab funding plan: take May delivery of as many barrels of crude oil as the lab can hold. Store until price gets back to the low low discount of $20 a barrel and sell. Don't write grants for a while.

@therealtglotch @StonyBrookChem What if I have a promising photocatalyst?
