Sample preparation for the analysis of nanoparticles in natural waters by single particle ICP-MS
(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 ...
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 ...
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. ...
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. ...
Pressure-induced change of d-d luminescence energies, vibronic structure and band intensities in transition metal complexes
(Taylor and Francis, 2006-08-16)
The effects of hydrostatic pressure on the luminescence spectra of tetragonal transition metal complexes with nondegenerate electronic ground states are analyzed quantitatively by means of models based on potential energy ...
Absorption and luminescence spectroscopy of transition metal compounds : from coordination geometries to excited-state properties
(Société de spectroscopie du Canada, 2008)
Absorption spectra of transition metal compounds
provide important experimental information for the
understanding of their chemistry. The combination with
luminescence spectra yields quantitative insight on
excited-state ...
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 ...
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 ...
