Huge thank you to my DMG (Delia Milliron Group) students and postdocs for the amazing send off at group meeting today. Go Blue! #ChemSky

A cake with blue and maize colored decoration, printed with DMG, the M resembling the University of Michigan logo and a scientific visualization of a localized surface plasmon resonance in a doped nanocrystal.

New #ChemRxiv #preprint from my group and collaborators @tmtruskett.bsky.social and @utmid-ir.bsky.social

Ultrastrong coupling and IR spectral design by assembling layers of plasmonic ITO nanocrystals in open cavities. Surprising disorder tolerance of polariton modes!

(right) Series of mid-IR reflectance spectra showing two dips to near-zero that become further apart as the number of nanocrystal layers in the assembly increases

Excited to share a new #ChemRxiv #preprint on collaborative work with @tmtruskett.bsky.social @texasche.bsky.social by Kofi Ofosu. We use small angle X-ray scattering to study attractions between nanocrystals induced by adding non-adsorbing polymers.

New ChemRxiv preprint on the impact of band bending-induced depletion layers in plasmonic metal oxide nanocrystals. These are prominent in In-doped CdO, resulting in strong LSPR modulation and impacting coupling in superlattices.

Our NSF MRSEC, the CDCM, has a new long-format podcast, The Materials Universe. I had the privilege to be interviewed by host Abbey Stanzione for Episode 2: podcasts.la.utexas.edu/the-material...
We discuss quantum dots, smart windows, fostering a sense of belonging, and more.
