In a new publication in The Journal of Inorganic Biochemistry , Andrew Clinger et al. investigate the effect of different sacrificial electron donors (SED) on N 2 reduction in the photocatalytic CdS QD MoFe protein biohybrid system. In this work, the efficiency of ascorbic acid was compared to dithionite, triethanolamine,...

Skylar was awarded a chemistry department fellowship that will fund research for the spring semester and summer. Congrats Skylar!

In a new publication in The Journal of Chemical Physics (special edition: Festschrift in honor of Louis Brus), Katie Shulenberger et. al. analyze power-dependent ultrafast transient absorption experiments on CdSe quantum dots with varying diameters and surface-capping ligands to quantitatively extract the spectra of excitons and biexcitons. They find that...

In a new publication in The Journal of Chemical Physics (special edition: The Physical Chemistry of Solar Fuels Catalysis), Lauren M. Pellows et al. use electron paramagnetic (EPR) spectroscopy to characterize photocatalytic E-state intermediates in the catalytic cycle of MoFe protein of the nitrogenase enzyme. Illuminating CdS quantum dot -...

Daria Sukhareva, a first year student, has joined the Dukovic group. Welcome Daria!

In a new paper in Nano Letters, Lauren Pellows et al. use microscale thermophoresis (MST) to show that the electrostatic binding interaction between nitrogenase MoFe protein and CdS quantum dots capped with negatively-charged mercaptoprionate ligands is similar in strength to the interaction between MoFe and its physiological redox partner ferredoxin...

A new article in inChemistry outlines the work of several researchers in the nanoscience field, including Dr. Dukovic. The projects discussed all use nanomaterials that have potential applications in combatting different climate challenges.

In a new publication in the Journal of the American Chemical Society, Vansuch et al. use cryo-annealing and electron paramagnetic (EPR) spectroscopy to probe an intermediate state in the catalytic cycle of nitrogenase. This work, led by our collaborators at NREL, begins with the illumination of CdS quantum dot -...

Dr. Sophia Click, a 2023 Ph.D. graduate from Vanderbilt University, has joined the group. Welcome Sophia!

In a new publication in the Journal of Physical Chemistry C, Ben Hammel and Leah Hall et al. study how compositional heterogeneity influences the absorption spectra of (Ga1-xZnx)(N1-xOx) nanocrystals. They used valence electron energy loss spectroscopy (VEELS) to study how compositional variation influences absorption within and between nanocrystals. Notably, a...
