Linking the chemical speciation of cerium to its bioavailability in water for a freshwater alga
(Wiley, 2015-03-13)
Over the past decade, researchers have begun to use metals of the lanthanide family for numerous applications, including liquid crystal display (LCD) screens, optical fibers, and laser technology. Unfortunately, little is ...
Metal-ligand bonding in six-coordinate d-block complexes probed by luminescence spectroscopy at variable pressure
(De Gruyter, 2022)
Luminescence spectra measured at variable pressure can reveal unique insight
on ground- and emitting state properties of transition metal compounds. This chapter
summarizes illustrative results for chromium(III) complexes ...
Colossal C130 fullertubes : soluble [5,5] C130-D5h(1) pristine molecules with 70 nanotube carbons and two 30-atom hemifullerene end-caps
(American Chemical Society, 2023-10-27)
We report the seminal experimental isolation and DFT characterization of pristine [5,5] C130-D5h(1) fullertubes. This achievement represents the largest soluble carbon molecule obtained in its pristine form. The [5,5] C130 ...
Distinguishing the effects of Ce nanoparticles from their dissolution products : identification of transcriptomic biomarkers that are specific for ionic Ce in Chlamydomonas reinhardtii
(Oxford University Press, 2020-12-11)
Cerium (Ce) is a rare earth element that is incorporated in numerous consumer products, either in its cationic form or as engineered nanoparticles (ENPs). Given the propensity of small oxide particles to dissolve, it is ...
Separation, detection and characterization of nanomaterials in municipal wastewaters using hydrodynamic chromatography coupled to ICPMS and single particle ICPMS
(Springer, 2016-03-12)
Engineered nanoparticles (ENP) are increasingly being incorporated into consumer products and reaching the environment at a growing rate. Unfortunately, few analytical techniques are available that allow the detection of ...
Detection and characterization of ZnO nanoparticles in surface and waste waters using single particle ICPMS
(American Chemical Society, 2015-04-29)
The increasing production of ZnO nanoparticles (nZnO) makes their analysis and characterization extremely important from an ecological risk perspective, especially at the low concentrations at which they are expected to ...
Quantification of ZnO nanoparticles and other Zn containing colloids in natural waters using a high sensitivity single particle ICP-MS
(Elsevier, 2019-03-08)
Inductively coupled plasma mass spectrometry in single particle mode (SP-ICP-MS) is becoming a powerful tool of choice for the quantification and characterization of metallic nanoparticles (NP) at very low concentrations. ...
Stable amide activation of N-acetylated glycosamines for the synthesis of fused polycyclic glycomimetics
(American Chemical Society, 2024-01-02)
N-Acetylation of carbohydrates is an underexplored target for chemoselective derivatization and generation of glycomimetic scaffolds. Through mild amide activation, we report that N-acetimidoyl heterocycles are stable in ...
Target and nontarget screening of PFAS in drinking water for a large-scale survey of urban and rural communities in Québec, Canada
(Elsevier, 2023-02-16)
Limited monitoring data are available regarding the occurrence of emerging per- and polyfluoroalkyl substances (PFAS) in drinking water. Here, we validated an analytical procedure for 42 PFAS with individual detection ...
Variable-pressure luminescence and Raman spectroscopy of molecular transition metal complexes : spectroscopic effects originating from small, reversible structural variations
(Royal Society of Chemistry, 2014)
The past ten years have seen a significantly increasing number of published crystal structures for molecular transition metal complexes at variable pressure, providing quantitative information on structural variations. ...
