In a system and a method for making carrier-free radioactive isotopic Gallium-68, stable enriched Zinc-68 is formed into a solid target of very high purity. The solid target of enriched Zinc-68 is exposed to a proton beam provided by irradiation in a cyclotron to change the enriched Zinc-68 into Gallium-68. After irradiation, the solid target contains high concentrations of Gallium-68 with only trace amounts of enriched Zinc-68 and isotopic Gallium-67. Gallium-68 is then further purified to remove the impurities resulting in a Gallium-68 composition with high purity and specific activity and without Germanium-68, Also provided are radiopharmaceutical agents that are labeled with the Gallium-68 compositions made by solid targeting in a cyclotron.

A method for producing carbon nanotubes includes subjecting a plastic material and an acidic zeolite to a pyrolysis reaction so as to form a hydrocarbon compound having 1 to 6 carbon atoms. The acidic zeolite has a molar ratio of SiO.sub.2 to Al.sub.2O.sub.3 ranging from 5.1:1 to 80:1. Another method for producing carbon nanotubes includes subjecting a hydrocarbon compound having 1 to 6 carbon atoms and a catalyst to a catalysis reaction so as to obtain the carbon nanotubes. The catalyst includes a support and a plurality of ferromagnetic nanoparticles supported on the support. The ferromagnetic nanoparticles have an average diameter ranging from 20 nm to 30 nm, and are derived from acetylacetonate of a ferromagnetic transition metal.
