Abstract: Chemical vapor deposition is performed using a plurality of expanding thermal plasma generating means to produce a coating on a substrate, such as a thermoplastic and especially a polycarbonate substrate. The substrate is preferably moved past the generating means. Included are methods which coat both sides of the substrate or which employ multiple sets of generating means, either in a single deposition chamber or in a plurality of chambers for deposition of successive coatings. The substrate surfaces spaced from the axes of the generating means are preferably heated to promote coating uniformity.

Abstract: A nanoparticle comprising an inorganic core and a polymerizable outer coating. The inorganic core comprises a substantially crystalline inorganic material such as a superparamagnetic material. In one embodiment, the inorganic core comprises a single crystal mixed spinel ferrite comprising iron in a first oxidation state and at least one metal in a second oxidation state, wherein the second oxidation state is different from the first oxidation state.
