Analyse des nanoparticules de dioxyde de cérium à l’aide de l’ICP-MS en mode particule unique
Jreije, Ibrahim (2022-06-22)Due to their unique properties, engineered nanomaterials are now widely used in numerous commercial products. Cerium oxide (CeO2) nanoparticles (NPs) are among the most commonly used engineered NPs, with applications in surface coatings, catalysis, the ... -
Biological impacts of Ce nanoparticles with different surface coatings as revealed by RNA-Seq in Chlamydomonas reinhardtii
Morel, Elise; Jreije, Ibrahim; Tetreault, Valerie; Hauser, Charles; Zerges, William; Wilkinson, Kevin James (Elsevier, 2020-05-18)In order to better understand the risks of engineered nanoparticles (ENPs), it is necessary to determine their fate and biological effects under realistic exposure scenarios (e.g. low ENP concentrations). RNA-Seq was deployed to characterize the ... -
Quantification and characterization of Ti-, Ce- and Ag5 nanoparticles in global surface waters and precipitation
Azimzada, Agil; Jreije, Ibrahim; Hadioui, Madjid; Shaw, Phil; Farner, Jeffrey M.; Wilkinson, Kevin James (American Chemical Society, 2021-06-28)Nanoparticle (NP) emissions to the environment are increasing as a result of anthropogenic activities, prompting concerns for ecosystems and human health. In order to evaluate the risk of NPs, it is necessary to know their concentrations in various ... -
Release of TiO2 nanoparticles from painted surfaces in cold climates : characterization using a high sensitivity single-particle ICP-MS
Azimzada, Agil; Farner, Jeffrey M.; Hadioui, Madjid; Liu-Kang, Carolyn; Jreije, Ibrahim; Tufenkji, Nathalie; Wilkinson, Kevin James (Royal Society of Chemistry, 2020)Paints and coatings represent one of the major applications of TiO2 nanoparticles (NPs). While it has been previously shown that NPs are released from painted surfaces, there is still a lack of experimental data on their release rates under natural ... -
Sample preparation for the analysis of nanoparticles in natural waters by single particle ICP-MS
Jreije, Ibrahim; Hadioui, Madjid; Wilkinson, Kevin James (Elsevier, 2021-11-12)With the significant increase in the production and use of nanoparticles (NP), concern is increasing over their release into their environment. Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) is emerging as one of the best ...
