A method for preparing a preblend of nano-structured 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 nano-structured carbon as the shell on the particulate solid core. The preblend may provide particularly improved dispersion of single-wall nanotubes in ethylene--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.

One aspect of the disclosure is directed to a method for activation/enhancement of cell growth of a plant.

The method includes providing a nano-sized material contained agent, and treating the plant with the nano-sized material contained agent to allow sufficient interaction of cells of the plant with the nano-sized material so as to activate/enhance the cell growth of the plant or to stimulate the production of pharmaceutically active metabolites.

A method for producing hydrogen (H.sub.2) from methane (CH.sub.4) includes introducing a feed gas stream containing CH.sub.4 into a reactor containing a nickel (Ni) and cobalt (Co)-based titania supported (NCT) catalyst; passing the feed gas stream through the reactor in contact with the NCT catalyst at a temperature of 600 to 1000 C. to convert CH.sub.4 to carbon (C) and H.sub.2, and produce an H.sub.2-containing gas stream leaving the reactor; and separating H.sub.2 from the H.sub.2-containing gas stream. The method has a CH.sub.4 conversion of up to 95% of the initial weight of CH.sub.4 and a H.sub.2 yield of up to 90% based on the CH.sub.4 conversion.

The present invention generally relates to a method for producing high-quality carbon nanotubes (CNTs) from readily available and cost-effective egg-derived precursors. The system comprises a precursor preparation unit capable of processing egg white and/or yolk into suitable forms for pyrolysis. This unit includes options for dehydration and grinding into powder, hydrothermal treatment for solution-based precursors, and a blender for combining egg white and yolk powders in a controlled ratio to tailor the nitrogen/carbon content of the resulting CNTs. A pyrolysis reactor subjects the precursor to catalytic pyrolysis in an inert atmosphere (e.g., Argon) at temperatures between 900 C. and 1000 C., utilizing an iron (Fe) catalyst. Downstream, a purification unit removes catalyst particles and by-products. A gas flow control system maintains the inert atmosphere within the reactor, ensuring consistent CNT formation. This system offers a sustainable and scalable approach to CNT synthesis, leveraging the unique properties of egg components.
