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 C60 molecules 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 C60 provides 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.

Provided are a method of efficiently procuding fullerene into which a OH group or a SO3H group is introduced, such as fullerenol, or a derivative thereof, the fullerene and its derivative being preferable as a proton conductor, and a novel and usable proton conductor obtained by the method. Further, provided is an electrochemical device using the proton conductor such as a fuel cell or the like. In the producing method of the fullerene derivative, halogated fullerene, which is obtained through halogating a fullerene molecule is used as a precursor, the fullerene derivative is produced through introducing one or more proton dissociative group into at least one carbon atom of a fullerene molecule. Moreover, in a producing method of a polymerized fullerene derivative, a plurality of fullerene derivatives are bonded to one another by an aromatic group of an aromatic compound through reacting the plurality of fullerene derivatives with the aromatic compound. The fullerene derivative obtained by any of these method functions as a proton conductor, and an electrochemical device using the proton conductor such as a fuel cell can be downsized and simplified without atmosphere constraints.

The invention relates to the application of carbon nanotubes in polyethylene fiber composite non-woven fabrics. The nanoparticles are two-dimensional nanometer carbon nanotubes, which are seamless hollow tubes surrounded by hexagonal carbon atom grids. Covered by large fullerene molecules with a diameter of a few tenths of nanometers to tens of nanometers and a length of several to hundreds of microns. Preparation includes: (1) Pretreatment of carbon nanotubes: purification and organic treatment; reflux 1-4g carbon nanotubes / ml and 0.01-0.04g / ml titanate coupling agent in organic solvent for 1-3 hours ; (2) Mix carbon nanotubes with adhesive, stir at 60-80°C for 1-2 hours, and vacuum defoam; (3) Spread the reinforcement UHMWPE fiber evenly on the winding machine; (4) Glue, the number of times 1-2 times, dry at 40-70°C; (5) Dry at 60±3°C after coating for 10-20min. The invention increases the use temperature of the polyethylene fiber composite non-weft fabric by 10°C, improves the impact resistance by 20%, has excellent heat resistance, strength and creep resistance, and can resist impact, bulletproof and knife stab.

A fusion fuel composition has two or more light nuclei combined with a cage-like molecule. The light nuclei may be, for example, deuterium and tritium, and the cage-like molecule may be, for example, a fullerene molecule. A fusion reaction to consume the fusion fuel may be ignited, for example, via compression methods including chemical or laser.
