Abstract: The invention relates to a method of processing graphene comprising the steps of: combining few-layer graphene with a poly(alkylene oxide); drying to form a graphene/poly(alkylene oxide) composite; and calcining the graphene/poly(alkylene oxide) composite thus formed in an inert atmosphere. The invention also relates to processed graphene comprising a few-layer feature, wherein the graphene further comprises one or more features selected from: in-plane nanopores with dimensions of from about 1.5 nm to about 3.5 nm; a greater than 50% expanded interlayer lattice; an expansion interlayer distance of greater than 3.40 Å; and an atomic O/C content of less than 4%. The invention further relates to cathodes and batteries comprising processed graphene, and the use of processed graphene in capacitive deionization or rechargeable battery applications.

Abstract: Particulate material comprising rough mesoporous hollow nanoparticles. The rough mesoporous hollow nanoparticles may comprise a mesoporous shell, the external surface of which has projections thereon, the projections having smaller sizes than the particle size. The particulate material may be used to deliver active agents, such as insecticides and pesticides. The active agents can enter into the hollow core of the particles and be protected from degradation by sunlight. The rough surface of the particles retains the particles on plant leaves or animal hair. Methods for forming the particles are also described. Carbon particles and methods for forming carbon particles are also described.
