Known techniques for forming nanoparticles require a multiple-step process to coat a surface with nanoparticles. The present invention provides a single-step process that requires the deposition of a substrate in a mixture of a solvent, ligands and organometallic precursors. The mixture containing the substrate is heated under pressure in a dihydrogen environment for a predetermined period of time, during which supercrystals of nanoparticles form on the substrate.

Method of coating a surface with nanoparticles

A magnetic nanoparticle (), a magnetic nanomaterial (), assembly (), and a method for synthsising a magnetic nanoparticle, relating to thermodynamically stable and air stable ferromagnetic nanoparticles of adjustable aspect ratio made upon decomposition of organometallic precursors in solution in the presence of a reaction gas and a mixture of organic ligands. The magnetic nanomaterial comprises magnetic nanoparticles of homogeneous size, shape, and magnetic orientation that comprises a magnetic core () ferromagnetic at room temperature and/or operating temperatures, and a non-magnetic matrix () encapsulating the magnetic core. This magnetic nanomaterial could be used in high frequency integrated circuit applications, such as used in wireless portable electronic devices, to enchance magnetic field confinement and improve passive component performance at MHz and GHz frequency in a variety of passive and active devices, such as transformers, on-chip signal isolation, inductors, and the like.
