Cooperative Activation of O2 by Heteronuclear Assemblies

Dioxgyen (O2) activation and reduction are not only vital for aerobic life, but also essential to industrial applications such as sustainable fuel cells. Dioxgyen is clean, abundant, and a powerful four-electron oxidant, but also kinetically inert and requires activation. In Nature, the activation of O2 is often facilitated by transition metal centers at metalloenzyme active sites. For example, during the cellular respiration reaction,…


Borafluorenes, Borepins, and High Order Boraacenes: From Fundamental Redox Chemistry to Thermochromic Materials

            The incorporation of boron into conjugated organic molecules has emerged as a useful strategy to elicit interesting optical and electronic properties which cannot be obtained with the analogous all-carbon systems. Thus, the synthesis of organoboron heterocycles has been a topic of intense investigation across main-group, organic, and inorganic chemistry, as well as materials…


Biochemically Responsive MRI Contrast Agents

Magnetic Resonance Imaging is a diagnostic method used to image organs and soft tissue in the body. The instrument relies on the use of magnets and radiofrequency radiation to examine the proton nuclei of water within tissue and organs. Through use of contrast agents, the images acquired can have improved detail which is critical for diagnoses of tumors, inflammation, and other abnormalities. These agents utilize paramagnetic metals to induce…


A Mechanistic Study of Coproheme Decarboxylase

Heme is an essential cofactor required for numerous biological reactions in the vast majority of organisms, and its biosynthesis is a complex process. Three heme biosynthetic pathways have been identified, with the most recent being the coproporphyrin dependent (CPD) pathway. In the CPD pathway, coproporphyrinogen III is oxidized to coproporphyrin, followed by iron insertion into the tetrapyrrole, forming coproheme1. The final step of the CPD…


Value-Added Reutilization, Recycling of Lithium-Ion Batteries

The demand of lithium-ion batteries is quickly increasing largely due to the increased production of electric vehicles.  This rise in battery production will lead to an equivalent rise in waste as these batteries are consumed and discarded.  Currently only about 5% of lithium-ion batteries are recycled1.  This low level of recycling is in part due to the cost to recycle and the limitations of the current technologies available at…


Metalloenzyme-Catalyzed Oxidations of Nitric Oxide in Biosynthesis and Nitrosative Stress Protection

Metalloproteins catalyze nitric oxide (NO) chemistries in bioenergetics pathways, natural product biosynthesis pathways, and to protect against cell damage caused by nitrosative stress. Our lab is interested in the mechanisms of oxidative NO-dependent metalloenzymes involved in natural product biosynthesis and nitrosative stress protection. Understanding the mechanisms of these enzymes will enable the engineering of nitration biocatalysts and…


Structure and Dynamics of Enzyme-Ligand Interactions

Essential across all domains of life, enzymes often expedite challenging biological reactions by incorporating transition metal ions whose oxidation and spin states are coordinated with changes in atomic structure. While great strides have been made in the field of metalloenzymology, our understanding of these dynamic processes remains limited as the timescales on which they occur render visualization technically challenging. In this talk, I…


Advances in Carbon-Supported, Iron-Containing Oxygen Electrocatalytic Cathodes in Zinc-Air Batteries

As the population and its demand for electricity increases, the call for renewable energy has been growing ever louder. Unfortunately, these energy sources (namely wind and solar power) can not always meet real-time needs. In order to gain the most from these energy sources while being able to cover their gaps in production, the need for storage of excess energy at the grid-level has become apparent. Current and planned bulk-energy storage…


Probing the Influences of a Lewis Acid on Mn (IV)-Oxo Bonds: A Guide Towards O-O Bond Formation

The process of photosynthesis has been intensely studied since its discovery in the late 1720’s.1 Understanding how plants oxidize water to O2 is of relevant importance due to its potential use in fuel cell technology. Water splitting cells generate H+ and electrons for the fuel cell to use. Inside the chloroplast, plants contain the oxygen evolving complex (OEC) a Mn4O5Ca cluster that is responsible for O2 evolution.2 It has been demonstrated…


Bismuth Nanoparticle Incorporated Composites for Lightweight Radiation Shielding

The development of radiation-based medical technologies, nuclear energy, and the ambitions of space exploration have greatly increased the incidence of human radiation exposure over the past decades. Given their exceptional radiation attenuating properties, lead-based materials have predominantly been used as the preferred shielding material for personnel and equipment. However, the toxicity and heavy weight of lead-based materials gives rise to…
