A periodic mesoporous organosilica (PMO) functionalized with sulfur units between the organic bridges has been successfully synthesized by a postsynthetic cold vulcanization treatment performed on an ethenylene-bridged PMO material (ethene-PMO). The results of X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and nitrogen adso...

La connaissance des flux de contaminants particulaires véhiculés par les cours d'eau est cruciale pour la gestion des pollutions environnementales, mais elle se heurte à d'importantes difficultés technologiques, méthodologiques et scientifiques. Grâce à un effrt d'observation intensive rendue possible par l'Observatoire des sédiments du Rhône, ce t...

A novel thiol functionalized bis-silane PMO precursor was synthesized by highly efficient thiol acid-ene chemistry between the double bonds of 1,2-(E)-bis(triethoxysilyl)ethene and thioacetic acid. After aminolysis the self-assembly process of the formed SH-precursor with Pluronic P123 under acidic conditions yields the first 100% thiol-PMO materia...

Photodegradation is an important sink for highly toxic methylmercury (MeHg) in aquatic ecosystems. Lakes have been extensively studied for MeHg photodegradation, but much less is known about streams, mainly because of the heterogeneity in sunlight availability along stream reaches and because there has been a lack of tools with which to integrate t...

Genetic engineering of plants for phytoremediation is thought to be possible based on results using model plants expressing genes involved in heavy metal resistance, which improve the plant's tolerance of heavy metals and accumulation capacity. The next step of progress in this technology requires the genetic engineering of plants that produce larg...

In vitro gastrointestinal (GI) microbial activity in the colon compartment facilitates the arsenic release from soils into simulated GI fluids. Consequentially, it is possible that in vitro models that neglect to include microbial activity underestimate arsenic bioaccessibility when calculating oral exposure. However, the toxicological relevance of...

A new BODIPY dye conjugate has demonstrated selective quenching by mercury over other metal ions. Coupling of this probe to Au-Fe3O4 nanoparticles as well as platinum electrodes offered sensitive systems for suspension and surface based sensing, respectively. / open / 1 / 1 / 27 / 28 / scie / scopus

Planar electrochemical microcells were micro-machined in a microcrystalline boron-doped diamond (BDD) thin layer using a femtosecond laser. The electrochemical performances of the new laser-machined BDD microcell were assessed by differential pulse anodic stripping voltammetry (DPASV) determinations, at the nanomolar level, of the four heavy metal ...
