A Large-scale Approach to Modeling Molecular Biosignatures: The Diatomics (2022)
Journal Article
Cross, T. M., Benoit, D. M., Pignatari, M., & Gibson, B. K. (2022). A Large-scale Approach to Modeling Molecular Biosignatures: The Diatomics. The Astrophysical journal, 925(1), Article 57. https://doi.org/10.3847/1538-4357/ac3976

This work presents the first steps to modeling synthetic rovibrational spectra for all molecules of astrophysical interest using a new approach implemented in the Prometheus code. The goal is to create a new comprehensive source of first-principles m... Read More about A Large-scale Approach to Modeling Molecular Biosignatures: The Diatomics.

Smolyak Algorithm Adapted to a System-Bath Separation: Application to an Encapsulated Molecule with Large-Amplitude Motions (2022)
Journal Article
Lauvergnat, D., Chen, A., Benoit, D. M., Scribano, Y., Nauts, A., & DavidLauvergnat. (2022). Smolyak Algorithm Adapted to a System-Bath Separation: Application to an Encapsulated Molecule with Large-Amplitude Motions. Journal of chemical theory and computation : JCTC, https://doi.org/10.1021/acs.jctc.2c00108

A Smolyak algorithm adapted to system-bath separation is proposed for rigorous quantum simulations. This technique combines a sparse grid method with the system-bath concept in a specific configuration without limitations on the form of the Hamiltoni...

Stark Effect Control of the Scattering Properties of Plasmonic Nanogaps (2022)
Journal Article
Pagnotto, D., Muravitskaya, A., Benoit, D. M., Bouillard, J. S. G., & Adawi, A. M. (2023). Stark Effect Control of the Scattering Properties of Plasmonic Nanogaps. ACS Applied Optical Materials, 1(1), 500–506. https://doi.org/10.1021/acsaom.2c00135

The development of actively tunable plasmonic nanostructures enables real-time and on-demand enhancement of optical signals. This is an essential requirement for a wide range of applications such as sensing and nanophotonic devices. Here we show that...

Bn2DT3A, a Chelator for 68Ga Positron Emission Tomography: Hydroxide Coordination Increases Biological Stability of [68Ga][Ga(Bn2DT3A)(OH)]− (2022)
Journal Article
Price, T. W., Renard, I., Prior, T. J., Kubíček, V., Benoit, D. M., Archibald, S. J., Seymour, A. M., Hermann, P., & Stasiuk, G. J. (2022). Bn2DT3A, a Chelator for 68Ga Positron Emission Tomography: Hydroxide Coordination Increases Biological Stability of [68Ga][Ga(Bn2DT3A)(OH)]−. Inorganic chemistry, 61(43), 17059–17067. https://doi.org/10.1021/acs.inorgchem.2c01992

The chelator Bn2DT3A was used to produce a novel 68Ga complex for positron emission tomography (PET). Unusually, this system is stabilized by a coordinated hydroxide in aqueous solutions above pH 5, which confers sufficient stability for it to be use...
