Non-conductive ferromagnets based on core double-shell nanocomposites for radio-electric applications

Takacs H., Viala B., Hermán V., Tortai J.-H., Duclairoir F., Alarcon Ramos J., Jouneau P.-H., Okuno H., Tallec G., CEA, FR

We report a novel flexible nanotechnology for consumer product engineering as a complementary approach from solid-state manufacturing techniques based on metallic nanoparticles and graphene chemistries. We describe two chemical routes for producing closely-packed disordered assemblies [...]

Record resistivity for in-situ grown horizontal carbon nanotubes interconnects

Dijon J., Ramos R., Fournier A., Fournier H., Le Poche H., Fournier A., Fournier H., Okuno H., Simonato J-P, CEA-Liten, FR

Carbon in the form of nanotubes (CNTs) and graphene is the only known material that can replace copper in integrated circuits to carry the high current densities associated with advanced interconnects. Its implementation is however [...]

Continuous Mass Production of Fullerenes and Fullerenic Nanoparticles by 3-Phase AC Plasma Processing

Fabry F., Gruenberger T.M., Gonzalez-Aguilar J., Okuno H., Grivei E., Probst N., Fulcheri L., Flamant G., Charlier J-C, TIMCAL Belgium S.A., BE

A patented plasma technology has been developed over the last ten years for the continuous mass production of fullerenes and fullerene soot by the core partners of a consortium (TIMCAL BELGIUM S.A., EMP-ARMINES and CNRS). [...]

Continuous Mass Production of Carbon Nanotubes by 3-Phase AC Plasma Processing

Fabry F., Gruenberger T.M., Gonzalez-Aguilar J., Okuno H., Grivei E., Probst N., Fulcheri L., Flamant G., Charlier J-C, TIMCAL Belgium S.A., BE

Currently known processes for carbon nanotube synthesis use either of the following methods: Arc, laser, solar, plasma or catalytic method. The first group, comprising the first four processes corresponds to the high temperature methods. Hereby, [...]
