Featured Publications

  1. "Ethanol Dehydration in HZSM-5 studied by Density Functional Theory: Evidence for Concerted Process," J. Phys. Chem A. (2015)

Illustration of reaction energy diagrams for the concerted (top) and the stepwise (bottom) reactions of ethanol dehydration in H-ZSM-5. The illustrations are on a grey background and show ethanol and its chemical formula on the left with a green arrow pointing right to ethylene and its chemical formula. In the background are a net-like structure and red, blue, and black square-peaked lines.

  1. "Quantum Mechanical Calculations suggest that Lytic Polysaccharide Monooxygenases employ a Copper-oxyl, Oxygen-rebound Mechanism," PNAS (2014)

Illustration of T. aurantiacus LPMO, represented by a light grey globular substance that is pyramidal in shape that sits on top of a bar of light green (cellulose) that is also globular in nature. There are purple hexagon and linear shapes in the lower portion of the light grey area (the LPMO active site) and dark green hatch marks and crosses all across the top of the light green bar (a cellulose chain in stick). To the right is a close-up of the purple-lined area.
