Latest Patents
Artman's latest patents focus on processes for forming nanoparticles. One of his patents describes a method for creating a metal or alloy nanoparticle that exhibits hysteresis at room temperature, featuring a carbon coating. The nanoparticle has a diameter ranging from approximately 0.5 to 50 nm and can be either crystalline or amorphous. This innovative process involves preparing graphite rods packed with magnetic metals or alloys, which are then subjected to a carbon arc discharge to produce soot containing the desired nanoparticles. The soot is subsequently processed using a magnetic field gradient to separate the nanoparticles from non-magnetic species.
Another patent by Artman details the formation of magnetic metal or metal carbide nanoparticles, also coated with carbon. These nanoparticles have a diameter between approximately 5 to 60 nm and may be crystalline or amorphous. The process begins similarly, with graphite rods packed with magnetic metal oxides, followed by a carbon arc discharge to generate soot. Again, a magnetic field gradient is employed to isolate the magnetic nanoparticles from non-magnetic materials.
