Résumé : International audience
Abstract View references (38)This work presents a facile, scalable method for the fabrication of graphene oxide-iron oxide (GO-Fe3O4) nanocomposites produced by co-precipitation of iron ions onto the GO surfaces in basic aqueous media. FTIR and XRD characterisation suggests that Fe3O4 was chemically anchored to the GO sheets, possibly via the carboxyl and hydroxyl groups. Small GO loadings of 0.5 and 1 wt% were not sufficient to alter the Fe3O4 structures. However, increasing the GO loading to 5 and 10 wt% resulted in significant loss in pore volume, thus suggesting the lamellar GO sheets decorated with Fe3O4 were assembling into GO-Fe3O4 nanocomposite stacks. It was found that the GO-Fe3O4 nanocomposites had an enhanced catalytic activity in the heterogeneous Fenton-like oxidation of Acid Orange 7 (AO7) compared to pure GO flat sheets and Fe3O4 nanoparticles. Interestingly, the GO-Fe3O4 nanocomposite with 5 wt% loading ratio exhibited the best catalytic activity with 76% degradation of AO7 dye observed within 90 min of reaction. This was attributed to the synergistic effect of GO by enriching the adsorbed AO7 molecules onto the nanocomposite to be further oxidised in the vicinities of active sites. This finding suggests the promising employment of GO-Fe3O4 nanocomposites in removing organic dyes from polluted water by heterogeneous Fenton-like reaction. © 2014 by American Scientific Publishers.

Résumé : Many works deal with the subsequence matching problem using automata structures. It is to decide, given two sequences $s$ and $t$, whether $s$ is a subsequence of $t$. Automata like the Directed Acyclic Subsequence Graph (DASG) or the Subsequence Automaton (SA) accept all subsequences of a set of texts. We focus on this last structure and provide some useful results upon dynamically updates of the SA. Indeed, sequences are indexed as soon as they are processed, allowing to dynamically add or to remove sequences from the set of indexed texts. Moreover, the highlight of these properties also makes it possible to update this automaton whenever a sequence of the set is modified.

Description : Le Contesté franco-brésilien est un différend soulevé entre les gouvernements français et brésilien, sur la question de la délimitation de la frontière entre la Guyane et le Brésil. Le protocole du 10 avril 1897, signé entre la France le Brésil détermine que la rivière Japoc ou Vincent Pinçon est l'Oyapoc et que la limite intérieure se forme à partir de la source principale de cette rivière jusqu'à la frontière hollandaise par la ligne de partage des eaux du bassin des Amazones qui, dans cette région est constituée dans sa presque totalité par la ligne de faîte des monts Tamuc-Humac.

Résumé : International audience
Based on their small size and genomic properties, ultrasmall prokaryotic groups like the Candidate Phyla Radiation have been proposed as possible symbionts dependent on other bacteria or archaea. In this study, we use a bipartite graph analysis to examine patterns of sequence similarity between draft and complete genomes from ultrasmall bacteria and other complete prokaryotic genomes, assessing whether the former group might engage in significant gene transfer (or even endosymbioses) with other community members. Our results provide preliminary evidence for many lateral gene transfers with other prokaryotes, including members of the archaea, and report the presence of divergent, membrane-associated proteins among these ultrasmall taxa. In particular, these divergent genes were found in TM6 relatives of the intracellular parasite Babela massiliensis.

Résumé : International audience
This work is concerned with the study of the tribologic properties of room temperature fluorinated graphite heat-treated under fluorine atmosphere. The fluorinated compounds all present good intrinsic friction properties (friction coefficient in the range 0.05–0.09). The tribologic performances are optimized if the materials present remaining graphitic domains (influenced by the presence of intercalated fluorinated species) whereas the perfluorinated compounds, where the fluorocarbon layers are corrugated (armchair configuration of the saturated carbon rings) present higher friction coefficients. Raman analyses reveal that the friction process induces severe changes in the materials structure especially the partial re-building of graphitic domains in the case of perfluorinated compounds which explains the improvement of μ during the friction tests for these last materials.

Résumé : International audience
In this chapter, the aim is the solving of variational inclusions fo the form 0_in f(x)+F(x), where f is a subanalytic and locally Lipschitz function, F is a set-valued map with closed graph. The methods are developped using the metric regularity of (f+F) or the Aubin property of (f+F)^{-1}, and often lead to a superlinear convergence.
