摘要： In one aspect, the invention relates to a method of synthesizing a nannoparticle/porous graphene composite, including dispersing porous graphene structures into a solvent to form a dispersion of the porous graphene structures therein, adding precursors of nanoparticles into the dispersion of the porous graphene structures in the solvent to form a precursor mixture, and treating the precursor mixture to form a nannoparticle/porous graphene composite. The composite is formed such that the nanoparticles are uniformly distributed in pores of the graphene structures. The composite is very useful as electrode materials in electrochemical devices, in which efficient ions and electron transports are required.

摘要： The present invention relates to a magnetic particle-containing water dispersion wherein the magnetic particles have a primary particle diameter of 5 to 15 nm and an average secondary particle diameter of 10 to 60 nm, and the water dispersion has a zeta potential of not more than -20 mV when a pH value of the water dispersion lies within the range of 6 to 8, and further a surface of the respective magnetic particles is coated with a carboxyl group-containing polymer. The magnetic particle-containing water dispersion is produced by heating an aqueous solution in which the carboxyl group-containing polymer is dissolved, to a temperature of 90 to 100°C in a nitrogen atmosphere; adding a solution of a ferrous (II) salt and a ferric (III) salt and an alkali solution to the aqueous solution to react with each other at the same temperature; adding ethanol to the solution to obtain a precipitate; and removing a supernatant liquid from the solution, and then dispersing the precipitate in water and subjecting the resulting dispersion to dialysis. The magnetic particle-containing water dispersion is useful as a magnetic particle-containing water dispersion capable of producing magnetic particle-containing drugs for diagnosis and therapies which can exhibit a uniform functionality, with a good reproducibility.
