A multi-layered, transparent-conductive stack with improved mechanical robustness, and a method of making the same, is described. The multi-layered film includes a layer of a hybrid film and a layer of a transparent conductive oxide (TCO) coating that is sputter deposited and forms a contact with the hybrid film. The hybrid film includes an interconnected network of carbon nanotubes (CNTs) and a plurality of metal oxide nanoparticles (MONs). The plurality of MONs are randomly distributed in the interconnected network of CNTs forming an electrical contact with the CNTs.

A method for preparing a 'preblend' of nanostructured carbon, such as nanotubes, fullerenes, or graphene, and a particulate solid, such as polymer beads, carbon black, graphitic particles or glassy carbon involving wet-mixing and followed by optional drying to remove the liquid medium. The preblend may be in the form of a core-shell powder material with the nanostructured carbon as the shell on the particulate solid core. The preblend may provide particularly improved dispersion of single-walled nanotubes in ethylene-&#x3b1;-olefin elastomer compositions, resulting in improved reinforcement from the nanotubes. The improved elastomer compositions may show simultaneous improvement in both modulus and in elongation at break. The elastomer compositions may be formed into useful rubber articles.

Embodiments of tunneling barriers and methods for same can embed molecules exhibiting a monodispersion characteristic into a dielectric layer (e.g., between first and second layers forming a dielectric layer). In one embodiment, by embedding Cmolecules inbetween first and second insulating layers forming a dielectric layer, a field sensitive tunneling barrier can be implemented. In one embodiment, the tunneling barrier can be between a floating gate and a channel in a semiconductor structure. In one embodiment, a tunneling film can be used in nonvolatile memory applications where Cprovides accessible energy levels to prompt resonant tunneling through the dielectric layer upon voltage application. Embodiments also contemplate engineered fullerene molecules incorporated within the context of at least one of a tunneling dielectric and a floating gate within a nonvolatile flash memory structure.
