Cyclic polymers do not contain end groups, and as a result they demonstrate a number of unique physical properties. For example, the density, refractive index, T_g, viscoelasticity, reptation, and surface properties of cyclic polymers all differ from those of their more common linear analogs. Over the past fifty years a handful of catalysts have been discovered that can create cyclic polymers. In this seminar, four new catalysts will be presented that are capable of creating cyclic polymers.

Transient absorption in the extreme ultraviolet and x-ray spectral regimes is used to probe chemical dynamics on both the femtosecond and attosecond timescales. Laser-produced high-order harmonics in the soft x-ray can investigate dissociating molecules, ring opening, passage through conical intersections, singlet to triplet transitions, and electronic and vibrational coherences.

Energy density and cost of Li-ion batteries (LIBs) based on conventional intercalation compounds are closely approaching their limits. The reliance of conventional cathodes on the use of toxic metals additionally endangers health and safety of miners in developing countries. Conversion-type active materials offer an opportunity to double energy stored in LIBs, reduce their cost by the same factor, and improve cell safety.

The University of Georgia Department of Chemistry is pleased to announce openings for two tenure track faculty positions.  Each position will begin on August 1, 2019, at the level of Assistant professor.

Misregulation of kinases is implicated in a myriad of diseases and significant efforts have been put forth towards the development of targeted kinase inhibitors.  However, many issues remain with current therapeutic strategies including specificity and inhibitor resistance.  As an alternative approach for targeted inhibition, we have developed inhibitors targeting protein-protein interfaces (PPIs) that bind evolutionarily conserved structural features for a kinase of interest.  These peptide-based inhibitors are chemically constr

The goal of deriving localized-orbitals as a means for describing transferable bonding orbitals or for more efficiently describing electronic correlation has a long history.
