New publication on geophysical sensing of engineered polymer-coated nanoparticles in aquifer sand

Wednesday, November 28, 2018

Environmental Science and Technology articles ASAP (as soon as publishable) now features a publication by Ecohydrology researchers Adrian Mellage, Laureline Vallée, Fereidoun Rezanezhad and Philippe Van Cappellen in collaboration with researchers from nanotechnology (https://www.frankgulab.com/). The paper titled “Sensing Coated Iron-Oxide Nanoparticles with Spectral Induced Polarization (SIP): Experiments in Natural Sand Packed Flow-Through Columns” (access here: https://pubs.acs.org/articlesonrequest/AOR-Bp4qycsemHXAtsIIcSqb) focuses on sensing engineered nanoparticles, designed for targeted hydrocarbon remediation, using spectral induced polarization (SIP). Time-lapse geophysical signals are coupled to a flow and transport model to relate these to nanoparticle concentrations in the direct vicinity of measurement electrodes. The paper highlights the applicability of SIP for real-time monitoring of nanoparticle migration in the subsurface.
