Iron based 1D Nanostructures by Electrospinning Process

Eid C., Brioude A., Salles V., Plenet J.-C., Asmar R., Monteil Y., Khoury A., Khoury R., Khoury A., Khoury R., Miele P., Université Claude Bernard-Lyon 1, FR

Due to their strong shape anisotropy, one-dimensional (1D) nanomaterials, including nanotubes, nanowires and nanofibers exhibit specific properties that are not observed in the case of their bulk or particle counterparts.1 Moreover, when such nanomaterials display [...]

Control of the morphology of nanoparticles resulting from the dynamic optimization of a fed-batch emulsion copolymerization process

Benyahia B., Latifi A., Fonteix C., Pla F., University of Nancy, FR

This paper deals with the design and the control of the morphology of core-shell nanoparticles elaborated by emulsion copolymerization of styrene and butyl-acrylate in the presence of n-dodecyl mercaptan, as a chain transfer agent (CTA). [...]

Design and multiobjective optimization of a novel reactive extrusion process for the production of nanostructured PA12/ PDMS blends

Pla F., Rached R., Hoppe S., Fonteix C., Nancy University, FR

The important demand of innovative materials implies the development of new processes and concepts for their design and optimization. This work deals with the manufacture, by reactive extrusion, of Polyamide 12 (PA12)/ Polydimethylsiloxane (PDMS) nanostructured [...]

Nanoparticle release from nano-containing product, introduction to an energetic approach

Gheerardyn L., Le Bihan O., Dore E., Morgeneyer M., INERIS, FR

The use of nanoparticles in manufactured products becomes more and more frequent and could lead to new potential risks for the workers, the consumers and the environment. This study focused on the R&D process of [...]

New method for the caracterization of abrasion-induced nanoparticle release into air from nanomaterials

Golanski L., Guiot A., Tardif F., CEA, FR

Nanotechnologies are emerging around the world. Nanoparticles are finding new industrial applications every day. Due to the variety of nanoparticles, toxicology studies will take time to establish the dangerousness of every kind of nanoparticle. Today [...]

Controlled Dispersion of Carbon Nanotubes Wrapped in Amphiphilic Block Copolymers: Elaboration of Polymer Nanocomposite

Semaan C., Pecastaings G., Schappacher M., Soum A., Laboratoire de Chimie des Polymères Organiques LCPO, FR

The scope of carbon nanotubes (CNT) applications in practical devices has been hampered by poor dispersion and weak interfacial bonding with polymer matrices. Therefore, effective method for CNT dispersion is required for industrial applications. We [...]

Review of Double Wall Carbon Nanotubes, Synthesis and Applications (overview presentation)

Bacsa W., University of Toulouse, FR

We find that the Raman G band for individual double wall carbon nanotubes is split when the two walls are closely spaced or strongly coupled. We show that agglomeration of tubes into bundles leads to [...]
