I first cut my teeth on quantitative materials criticality research back in 2012 as a postdoc UCSB . We dug through PDF after PDF in the USGS Mineral Commodity Summaries in a painstaking process of extracting reserve and production values for minerals on a country-by-country,

I’m taking a break from my mental health to focus on my academic work

Finally, back to doing what I love.. crystallography. Thanks to my postdoc Ben for these beautiful crystals! 😍💎 Warwick Chemistry

We discovered an in crystallo organometallic isomerization that shows 4f-orbitals can (uniquely) promote chemical reactions among isostructural 3d, 4d, 5d, 4f, & 5f complexes! Check out our latest paper, out now Nature Chemistry rdcu.be/eiVZw

In their latest work, Eric J. Schelter and his colleagues have shown that 4f orbitals can play an essential role in guiding the reaction of a molecule attached to a lanthanide. cen.acs.org/materials/inor…

Rare earth separations!

Happy End of Semester! Our Penn Chemistry students have done great learning about rare earths and actinides in "CHEM 7650 Chemistry of the f-Block Elements"! Shown here observing UO22+ luminescence under sunlight irradiation. Thanks Sarah ⌬ for demoing your 238U-duck in class!

The lanthanide elements’ 4f electron orbitals are notoriously shy and retiring. Now chemists have brought out a surprising extrovert streak in these orbitals, this is the first clear example of 4f bonding actually steering the course of a reaction: doi.org/10.1038/s41557….

Here is our investigation on new tunable ligands in cerium photocatalysis under mild conditions. Congrats to Nico! Chemistry Green‐light Cerium Photocatalysis enabled by Pyridine N‐oxide Ligands doi.org/10.1002/ejoc.2…

Congrats to all graduates at this weekend’s Penn graduation! Special shout-out to former group member Cami, pictured with Max from the SchelterGroup lab

Nice way to start the week :3

Did you know? If relativity did not play a role, a piece of gold would look gray. Relativity contracts the 6s orbital & lowers its energy, and does the opposite with the 5d orbitals. Optical absorption, due to the 5d->6s transition, is in the blue, so the color of gold is yellow!
