High temperature process for producing fine magnetic particles of M-phase structure

Abstract: A method for producing fine magnetic particles having the barium or strotium ferrite M-phase crystal structure. An iron and alkaline earth metal halide feed solution is vaporized to form a precursor and oxidizing vapor phase. The precursor and hydrolyzing or oxidizing vapor phases are held in a reactor at a temperature sufficient to effect vaporization of the feed solution yet which is below the melting point of the desired M-phase crystal structure. Small iron oxide particles precipitate from the vapor phase and alkaline earth oxides thereafter. The alkaline earth oxide particles diffuse into the iron oxide particles to form the desired M-phase structure. When the desired width and thickness of the M-phase crystal platelets is achieved, the M-phase particles are cooled by quenching. Composition of the feed solution may be modified by substituting divalent metal halides for the alkaline earth metal halide or by substituting trivalent halides or a combination of a divalent metal halide and either a penta or quatravalent metal halide for the ferric halide.

Circuit modeling and selective deposition

Abstract: A process for fabricating an electrical component using an ink-jet printing process is provided. The process includes the steps of selecting at least one electronic ink having at least a first functionality when cured; determining a positional layout for a plurality of droplets of the electronic ink(s) such that, based at least on the first functionality, the positional layout provides a desired response for the electrical component; providing at least a first characteristic that relates to the electrical component; comparing the determined positional layout to at least one corresponding entry in a lookup table of empirical data relating to the first characteristic and to the determined positional layout; adjusting the determined positional layout accordingly; and printing each of the droplets of the electronic ink(s) onto a substrate according to the adjusted positional layout. The step of determining a positional layout may include determining a volume of ink to be deposited.

Oil emulsification and polycyclic aromatic hydrocarbon adsorption using fine particles as dispersants

Abstract: A method for cleaning an oil spill in a marine environment includes forming a particle-stabilized emulsion containing seawater, carbon black and at least one oil spill component and allowing the at least one oil spill component to degrade, thereby removing said component from the marine environment. Carbon black can be added to an oil-seawater mixture to form a stabilized emulsion containing at least one oil spill component and the oil spill component allowed to degrade, thereby removing the at least one oil spill component from the oil spill. Also disclosed is an emulsion that includes one or more oil spill components, seawater and carbon black particles.
