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 properties, in particular ... -
Azobenzene molecular glasses with tuned glass transition temperatures : from optimal light‐induced motion to self‐erasable gratings
(Royal Society of Chemistry, 2020-04-01)The rate of photomechanical formation of surface relief gratings (SRG) in thin films of azobenzene materials depends on their glass transition temperature (Tg), with an optimal Tg around 50–60 °C yielding the fastest SRG growth. Herein, the SRG growth ... -
Biological impacts of Ce nanoparticles with different surface coatings as revealed by RNA-Seq in Chlamydomonas reinhardtii
(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 ... -
Bridging the gap between the mesoscopic 2D order–order transition and molecular-level reorganization in dot-patterned block copolymer monolayers
(American Chemical Society, 2016-11-21)Langmuir–Blodgett (LB) films of amphiphilic block copolymers (BCs) form well-defined nanostructures with long-range order useful, for instance, for nanolithography applications. Nanostructures with a 2D circular micelle (“dot”) morphology are known to ... -

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 ... -
Covalently crosslinked mussel byssus protein-based materials with tunable properties
(Wiley, 2018-03-01)Mussels’ anchoring threads, named byssus, are collagen-rich fibers with outstanding mechanical properties. Our previous work has shown the possibility of producing a byssus protein hydrolyzate with good film-forming ability, providing a promising new ... -
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 be found in natural waters. ... -
Development of an LC-MS-based method to study the fate of nanoencapsulated pesticides in soils and strawberry plant
(Elsevier, 2021-12-04)The increased production and use of nanopesticides will increase the likelihood of their exposure to humans and the environment. In order to properly evaluate their risk, it will be necessary to rigorously quantify their concentrations in major ... -
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 unclear whether biological ...
