Featured article: Density functional theory modeling of chromate adsorption onto ferrihydrite nanoparticles

In this study, part of the “Frontiers and Advances in Environmental Soil Chemistry” collection in honouring the work of Prof. Donald Sparks, James Kubicki and colleagues, perform DFT calculations on a model of a ferrihydrite nanoparticle interacting with chromate in water. Two configurations each of monodentate and bidentate adsorbed chromate as well as an outer-sphere and a dissolved bichromate were simulated. In addition to the 3-D periodic planewave DFT models, molecular clusters were extracted from the energy-minimized structures.

Dr Daniel Alessi

Dr. Daniel S. Alessi 

Dr. Alessi is a professor in the Department of Earth and Atmospheric Sciences at the University of Alberta and specializes in environmental geochemistry and geomicrobiology. His research group focuses on: (1) understanding the surface chemistry and reactivity of environmental materials such as iron oxides, bacteria, and biochar, to determine their impacts on elemental speciation and cycling in the environment, (2) on the development of methods to extract lithium and other elements critical for the manufacturing of electronics and clean energy technologies, and (3) on improving our knowledge of the water cycle in unconventional oil and gas operations. Dr. Alessi holds the Encana Chair in Water Resources and was elected a member of the College of New Scholars, Artists and Scientists of the Royal Society of Canada in 2022.
