摘要： The invention relates to producing magnetic fluids and to novel material synthesis. The inventive method for producing nanoparticles for magnetic fluids by electron-beam evaporation and condensation in vacuum consists in evaporating an initial solid material and in fixing nanoparticles of this material on a cooled substrate by means of a solidifiable carrier during vapour condensation, wherein a solid inorganic magnetic material, which is selected from a group containing metals, alloys or oxides thereof, is used as an initial material and a solid liquid-soluble material is used as a carrier material for fixing nanoparticles of the magnetic material. The method further consists in simultaneous evaporating the initial material and carrier composition, in which the carrier concentration ranges from 99 to 70%, by electron-beam heating. The vapour is deposited on the substrate, the temperature of which is set and maintained at a specified value, which is lower than the melting point of the carrier material, and the condensate of magnetic material nanoparticles, which have specified size and are fixed in the solid carrier, is produced. The particle size is adjusted by setting the specified temperature of the substrate during vapour deposition. A solid inorganic material, which is selected from a group containing salts of alkali and alkali-earth metals and mixtures thereof is used in the form of a carrier material used for fixing nanoparticles. The nanoparticles are extracted from the above-mentioned condensate by diluting it in at least one type of liquid, and by stabilizing by a surface-active agent. A method for producing a magnetic fluid, which contains magnetic material nanoparticles of the specified size, is also described, in which it is produced by dissolution in at least one fluid of the condensate of magnetic material nanoparticles of the specified size fixed in the solid carrier, which nanoparticles are produced by simultaneous electron beam evaporation with subsequent deposition on the substrate, the temperature of which is set and maintained at a certain level below the temperature of the carrier material melting, of a composition of solid inorganic magnetic material selected from a group, which includes metals, alloys and their oxides, and of a solid carrier soluble in the fluid, which fixes the nanoparticles, and which is selected from a group of inorganic materials, including the salts of alkali, alkaline-earth metals and their mixtures, and stabilization of the nanoparticles in the above fluid by a surface-active agent.

摘要： A method to preparing suspensions of metal or metal alloy nanoparticles in an ionic liquid involves the physical vapor deposition of a metal or a mixture of metals onto an ionic liquid. The method can be modified by the introduction of a reagent during or after formation of the suspension to yield nanoparticles of a metal salt.

摘要： A system and method for high volume production of nanoparticles, nanotubes, and items incorporating nanoparticles and nanotubes. Microwave, radio frequency, or infrared energy vaporizes a metal catalyst which, as it condenses, is contacted by carbon or other elements such as silicon, germanium, or boron to form agglomerates. The agglomerates may be annealed to accelerate the production of nanotubes. Magnetic or electric fields may be used to align the nanotubes during their production. The nanotubes may be separated from the production byproducts in aligned or non-aligned configurations. The agglomerates may be formed directly into tools, optionally in compositions that incorporate other materials such as abrasives, binders, carbon-carbon composites, and cermets.

摘要： Nanoparticles of intermetallic alloys such as FeAl, Fe3Al, NiAl, TiAl and FeCoV exhibit a wide variety of interesting structural, magnetic, catalytic, resistive and electronic, and bar coding applications. The nanosized powders can be used to make structural parts having enhanced mechanical properties, magnetic parts having enhanced magnetic saturation, catalyst materials having enhanced catalytic activity, thick film circuit elements having enhanced resolution, and screen printed images such as magnetic bar codes having enhanced magnetic properties. In contrast to bulk FeAl materials which are nonmagnetic at room temperature, the FeAl nanoparticles exhibit magnetic properties at room temperature.
