10/25/22 at 4:00pm in Chemistry A101

About the Seminar: Widespread adoption of renewable energy is limited by the lack of low-cost long-duration energy storage. Redox flow batteries (RFBs) are an attractive option to meet this energy storage need because their power and energy components can be scaled independently by storing energy with redox-active materials dissolved in solution. To date, RFB electrolytes […]

Literature Seminar: Lithium Metal Batteries (LMBs) are an exciting alternative to Lithium-ion Batteries (LIBs) due to the theoretical capacity of Li-metal anodes (3861 mAh/g). Despite this excitement, LMBs are plagued by gross instability during the Li plating/stripping process, which is thought to result from the formation of an unstable Solid-electrolyte Interphase (SEI). Much work has […]

Literature Seminar: Oxynitrides and their ability to be synthesized are an important facet in the solid-state chemistry field. Their properties are more tunable than in their single-anion counterparts as anions exhibit different characteristics (i.e. electronegativity) that contribute to the overall properties of the material. However, difficulty in their synthesis arises due to the intrinsic stability […]

Literature Seminar: Achieving luminescence with earth abundant metals at room temperature is a difficult task to this day. Minimal overlap between ligand and 3d orbitals means there are more low energy metal centered states which favor non radiative relaxation back to the ground state rather than luminescence.

Nature has inspired inorganic chemists to look beyond the immediate coordination sphere of complexes to tune and optimize reactivity. Two important themes have been the use of pendant proton donors/acceptors as well as incorporating redox-active moieties into ligand scaffolds. However, nature does not limit itself to an “either/or” strategy, and uses both of these features […]

Literature Seminar Abstract: Metalloenzymes drive chemical processes across life forms and mimicking this reactivity still remains a synthetic challenge. Almost all metalloenzyme active sites are composed of transition metals. In 2007 in volcanic mudpools in southern Italy, the bacteria Methylacidiphilum fumariolicum was discovered with an enzyme containing a lanthanide active site in a methanol dehydrogenase […]

We have developed a family of selective organic catalysts for ring-opening polymerization reactions.1,2  In parallel efforts, we have developed new oxidation catalysts2 that generate new monomers which were then enchained using organocatalytic polymerization1 to generate functional materials that proved useful agents for the delivery of messenger RNA into living animals.4-6 Functional delivery of messenger RNA […]
