Abstract: A method of making cerium dioxide nanoparticles includes: a) providing an aqueous reaction mixture having a source of cerous ion, a source of hydroxide ion, a nanoparticle stabilizer, and an oxidant at an initial temperature no higher than about 20° C.; b) mechanically shearing the mixture and causing it to pass through a perforated screen, thereby forming a suspension of cerium hydroxide nanoparticles; and c) raising the initial temperature to achieve oxidation of cerous ion to eerie ion and thereby form cerium dioxide nanoparticles having a mean diameter in the range of about 1 nm to about 15 nm. The cerium dioxide nanoparticles may be formed in a continuous process.

Abstract: Graphene layers made of primarily sp2 bonded atoms and associated methods are disclosed. In one aspect, for example, a method of forming a graphite film can include heating a solid substrate under vacuum to a solubilizing temperature that is less than a melting point of the solid substrate, solubilizing carbon atoms from a graphite source into the heated solid substrate, and cooling the heated solid substrate at a rate sufficient to form a graphite film from the solubilized carbon atoms on at least one surface of the solid substrate. The graphite film is formed to be substantially free of lattice defects.
