Electrospun materials with high reflectance and polarization contrast for sensing applications in the mid-infrared atmospheric window
(American Chemical Society, 2024-06-06)Several applications in remote sensing and thermal management require materials with high reflectivity and polarization contrast in the mid-infrared (MIR) spectral range. However, the existing options often fall short in terms of mechanical properties ... -
Engineered robust hydrophobic/hydrophilic nanofibrous scaffolds with drug-eluting, antioxidant, and antimicrobial capacity
(American Chemical Society, 2024-05-22)Multifunctional nanofibrous architectures have attracted extensive attention for biomedical applications due to their adjustable and versatile properties. Electrospun fabrics stand out as key building blocks for these structures, yet improving their ... -
Heterogeneous electron transfer of ferrocene in acetonitrile-LiTFSI highly concentrated electrolyte
(Elsevier, 2023-11-07)Highly concentrated electrolytes (HCE) are mixtures of equivalent or near-equivalent amounts of salt and solvent displaying a liquid phase at room temperature. HCE have intensively studied for application in energy storage devices with a particular ... -
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 species is the highest aspect ... -
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 neutral or basic conditions yet ... -
Molecular-level photo-orientation insights into macroscopic photo-induced motion in azobenzene-containing polymer complexes
(American Chemical Society, 2021-07-13)As part of continuing efforts to deepen the understanding of photo-induced mass transport in azo-containing polymers, we compared the diffraction efficiency (DE) during surface-relief grating (SRG) inscription, photo-induced molecular orientation (<P2>), ... -
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 limits of 0.001–0.082 ng/L. We ... -
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 with the d3 electron configuration ... -
Mixtures of rare earth elements show antagonistic interactions in Chlamydomonas reinhardtii
(Elsevier, 2021-06-14)In order to better understand the environmental risks of the rare earth elements (REEs), it is necessary to determine their fate and biological effects under environmentally relevant conditions (e.g. at low concentrations, REE mixtures). Here, the ...
