Testing methods to assess both the efficacy and ecotoxicity of antifouling coatings
Provedor de dados: 5
Autores: Quiniou, Francoise; Compere, Chantal; Caisey, Xavier; Davy, Romain; Matarere, Marcel; Mazeas, Florence; Peleau, Michel.
Since 1998, the European Biocidal Products Directive (BPD; 98/8/EC), applied to 23 product types (PT) for specific uses, including PT 21 the « antifouling products », regulates biocidal products before they are placed on the market.  On the one hand, the efficacy of active substances and their formulations must be demonstrated for their specific employment ; on the other hand their non impact on workers neither users and environment must be proved and specifically against non target species.  Standard protocols for the assessment of efficacy or ecotoxicity of antifouling substances are proposed within the framework of the Ecopaint and Paintclean projects which are founded by the french industry Ministery and labellised by the “Pôle Mer” (Paca and...

full-scale mechanical prototype line was deployed to a depth of 2500 m to test the leak tightness of the electronics containers and the pressure-resistant properties of an electromechanical cable under evaluation for use in the ANTARES deep-sea neutrino telescope. During a month-long immersion study, line parameter data were taken using miniature autonomous data loggers and shore-based optical time domain reflectometry. Details of the mechanical prototype line, the electromechanical cable and data acquisition are presented. Data taken during the immersion study revealed deficiencies in the pressure resistance of the electromechanical cable terminations at the entry points to the electronics containers. The improvements to the termination, which have been...

Protection par voie électrochimique de hublots immergés en milieu marin vis-à-vis des biosalissures
Provedor de dados: 5
Autores: Cachet, H.; Festy, Dominique; Folcher, G.; Mazeas, Florence; Tribollet, B.
Biofouling reduction is a major problem for underwater instrumentation, involving optical measurements or viewing. This paper presents an effective window protection technique based on seawater electrolysis for producing active chlorine species. This is achieved by depositing a transparent conductive tin dioxide coating by spray pyrolysis. A number of laboratory and in situ experiments were performed in order to assess the effectiveness of this window protection technique. It was found that Sb doping was more efficient with respect to electrical energy management and long term SnO2 coating stability than the fluorine doping. In the present state of the art, biofouling prevention was proved to be effective over 5 months at least

Biosensors for the detection and monitoring of Alexandrium minutum along the French coasts
Provedor de dados: 5
Autores: Antoine, Elisabeth; Compere, Chantal; Cosnier, Serge; Crassous, Marie-pierre; Derbal, Hassina; Erard-le Denn, Evelyne; Gondran, Chantal; Guilminot, Elodie; Lehaitre, Michel; Mazeas, Florence; Moreau, Hervé; Perrot, Hubert; Pradier, Claire-marie; Salmain, Michèle.
The microalgae Alexandrium minutum produces neurotoxins responsible for paralytic shellfish poisoning, which upon accumulation in shellfish represent a human health risk. This species recurrently forms toxic blooms in the Northern part of the French Brittany coast. At present, algae identification relies on tedious microscope observations mostly performed by skilled taxonomists in laboratories. Newly emerging fields of molecular taxonomy, nanoscale technology and biotechnology offer opportunities for the development of in-situ biosensors for the detection and the monitoring of toxic algae.

Thermoplastic composite cylinders for underwater applications
Provedor de dados: 5
Autores: Davies, Peter; Riou, Luc; Mazeas, Florence; Warnier, Philippe.
A study of thermoplastic matrix composites has been performed to investigate their use in underwater applications such as oceanography, submarine, and sub-sea offshore structures. This article first presents six candidate materials. Results from simple mechanical and seawater aging screening tests on flat specimens are then described. Glass/epoxy and carbon/epoxy composites are used as reference materials. Two materials emerged from this process, glass/PEI and carbon/PEEK. Cylinders of both were manufactured and subjected to hydrostatic pressure tests, and results are compared to those for glass/epoxy and carbon/epoxy cylinders of similar geometry. The carbon/PEEK material appeared most promising. It resisted pressures in excess of 90 MPa and was retained...

In situ measurement with diffusive gradients in thin films: effect of biofouling in freshwater
Provedor de dados: 5
Autores: Uher, Emmanuelle; Compere, Chantal; Combe, Matthieu; Mazeas, Florence; Gourlay-france, Catherine.
Concerning in situ passive sampler deployment, several technical priorities must be considered. In particular, deployment time must be sufficiently long not only to allow a significant quantity to be accumulated to facilitate analysis but also to ensure that the signal is above the quantification limit and out of the blank influence. Moreover, regarding the diffusive gradient in thin films (DGT) technique, deployment time must also be sufficiently long (at least 5 days) to avoid the interactions of the solutes with the material diffusion layer of the DGT and for the steady state to be reached in the gel. However, biofouling occurs in situ and modifies the surface of the samplers. In this article, we propose a kinetic model which highlights the biofouling...
