Accelerated Microdroplets Reactions: Mechanism and Applications in Materials and Organic Synthesis

Two publications from this lab, in 2011 and 2012, used mass spectrometry to show that the rates of reactions in microdroplets are accelerated by many orders of magnitude. These experiments used ordinary organic solvents and demonstrated that acceleration occurs at the solution/air interface.  These observations were then extended to a range of classical organic reactions. The Zare group showed reaction acceleration in aqueous microdroplets, for oxidation and other reactions.  

Hydrocarbons and Triplet Oxygen Radicals in Helium Nanodroplets - Generation from Precursors and High Resolution IR Spectroscopy

Helium Nanodroplet Isolation Spectroscopy (HENDI) is an excellent method for probing molecules and reaction systems effectively due to the unique characteristics it possesses such as superfluidity below a threshold temperature, optical transparency and weak interaction strength. The ultra-low temperature of this experiment also helps with the study of reactive species as low activation barriers remain thermally inaccessible.

Navigating the Mechanistic Controversy of Frustrated Lewis Pairs

Since its first discovery in 2006, Frustrated Lewis Pairs (FLPs) have attracted widespread attention for their ability to activate small molecules without transition metals. However, the exact mechanism of this activation remains a subject of debate. This seminar compares the two mechanistic models (the electron transfer (ET) and electric field (EF) models) and investigates the underlying physics governing these systems.

Quantification of Black Carbon and Its Coatings Based on Biomass Burning Conditions During G-WISE 2

In 2025, the second iteration of a multidisciplinary campaign known as the Georgia WIldland-fire Simulation Experiment (G-WISE 2) was conducted. G-WISE 2 focused on how different wildfire fuel conditions, such as fuel bed moisture, mass loading, and the inclusion of a high organic fuel known as duff (Zhang et al, 2022), influenced the aerosols produced from the combustion of the fuel beds.

Towards the Observation of Dimagnesocene

We have examined the electronic structure of C5H5MgMgC5H5, or dimagnesocene, using high-level coupled cluster techniques. This research is suitable in light of the remarkable synthesis of the valence-isoelectronic diberyllocene by Boronski, Crumpton, Wales, and Aldridge. The Mg-Mg bond distance is predicted to be 2.758 Å, and the Mg-Mg bond dissociation energy is predicted to be 51.8 kcal/mol.
