Turning metals cations into catalytic nanoparticles on modified electrode: a general strategy for their electrochemical quantification

Ambre Brachfeld, Giorgio Mattana, Agathe Laës, Vincent Noël et autres

• Cu and Fe pre-accumulated on modified graphite electrodes form a nanoelectrode array by electrochemical reduction. • Cu and Fe nanoelectrode array dimensions tune the catalytic HER peak potential in cyclic voltammetry. • Peak shifts in electrocatalytic HER voltammetric curves enable accurate …

The EMSO-Azores deep-sea observatory: 15 years of multidisciplinary studies of the lucky strike hydrothermal system, from sub-seafloor to the water column

Marjolaine Matabos, Mathilde Cannat, Valérie Ballu, Thibaut Barreyre et autres

Faced with climate change and the increasing interest for the deep ocean and ocean resources exploitation in particular, there is an urgent need for more comprehensive studies of deep-sea ecosystems. Hydrothermal vents are key areas for thermo-chemical exchanges between the lithosphere and …

Development of a new submersible colorimetric sensor for in situ detection of pHT on profiling floats

Romain Davy, Rémi Courson, Florence Salvetat, Xavier André et autres

The international BioGeoChemical-Argo program recommends the measurement of 6 essential ocean variables (EOVs), one of which being the inorganic carbon. Estimates of pH variation in the open ocean using traditional sampling methods show a decrease of 0.002 units per year [1]. Understanding …

Intercomparison and distribution of pHT in the Bosphorus Strait and Black Sea

Rémi Courson, Agathe Laës, Romain Davy, Florence Salvetat et autres

Understanding and predicting pH distributions through accurate and certified in situ detection is currently crucial. As part of the European BRIDGE Black Sea project, surface pHT transects were carried out in July 2024 across the Marmara Sea, the Bosphorus Strait and the …

Adaptation of a rFIA-GOF method for measuring Cu concentrations in estuarine waters

Agathe Laës, Chloé Mordant, Romain Davy, Maria El Rakwe et autres

In this study, we adapted copper quantification to the CHEMINI instrumentation [1] using the colorimetric method based on reverse flow analysis (rFIA) with liquid core wavelength (GOF) detection, as recently described [2]. This method relies on the reduction of ferricyanide by L-glutathione …

Fluid chemistry alters faunal trophodynamics but not composition on the deep-sea Capelinhos hydrothermal edifice (Lucky Strike vent field, Mid-Atlantic Ridge)

Joan Manel Alfaro-Lucas, Daniel Martín, Loïc N. Michel, Agathe Laës et autres

Abstract The recently discovered deep-sea Capelinhos hydrothermal edifice, ~ 1.5 km of the main Lucky Strike (LS) vent field (northern Mid-Atlantic Ridge), contrasts with the other LS edifices in having poorly-altered end-member hydrothermal fluids with low pH and chlorine, and high metal …

OT6.229 - Electrochemical assay for metal traces in marine environment by the Peaks Shift Analysis during catalysis

Ambre Brachfeld, Lylian Challier, Vincent Noël, Agathe Laës

An innovative electrochemical methodology is proposed for the quantitative in situ detection of trace metals in marine environment.This new method uses electrocatalysis to detect the catalyst instead of the substrate of the catalyst.As an example, we demonstrate that peak potential of proton …
