摘要： Inventive techniques for forming unique compositions of matter are disclosed, as well as various advantageous physical characteristics, and associated properties of the resultant materials. In particular, particles comprising polymer matrices are characterized by having carbon disposed within the polymer matrix structure thereof. The carbon is primarily, or entirely, present at interstitial sites of the polymer matrix, and may be present in amounts ranging from about 15 wt % to about 90 wt %. The carbon, moreover, forms covalent bonds with both atoms of the polymer matrix and other carbon atoms present in, but not part of, the matrix. This facilitates substantially homogeneous dispersal of the carbon throughout the resultant material, conveying unique and advantageous properties such as strength-to-weight ratio, density, mechanical toughness, sheer strength, flex strength, hardness, anti-corrosiveness, electrical and/or thermal conductivity, etc. as described herein. In some approaches, the resultant materials may be powderized or pelletized.

摘要： Provided are a method and apparatus capable of producing fine particles with favorable particle size distribution. In a production method in which feedstock for fine particle production is supplied intermittently into a modulated induction thermal plasma flame, the feedstock is vaporized to form a gas phase mixture, and the mixture is cooled to produce the fine particles: a modulated induction thermal plasma flame in which the temperature state is time-modulated is generated; the modulated induction thermal plasma flame is switched between a high temperature state and a low temperature state; and when the modulated induction thermal plasma flame is in the high temperature state, the feedstock is supplied together with a carrier gas, and when the modulated induction thermal plasma flame is in the low temperature state, supply of the feedstock is suspended and a gas of the same type as the carrier gas is supplied.

摘要： Apparatuses and methods for producing covetic materials by exciting a hydrocarbon gas with pulse microwaves to form hydrocarbon radicals in a hot first region of a microwave reactor. Graphene nanoplatelets are formed by the nucleation, growth, and assembly of the hydrocarbon radicals, and contact a metal melt introduced downstream of the hot region to produce a mixture of molten metal and graphene nanoplatelets which assemble in-flight to form covetic materials.

摘要： A plasma-generation system is provided that includes a variable-frequency microwave generator configured to generate microwave power and a plasma applicator configured to use the microwave power from the microwave generator to (i) ignite a process gas therein for initiating a plasma in a plasma ignition process and (ii) maintain the plasma in a steady state process. The system also includes a coarse tuner connected between the microwave generator and the plasma applicator. At least one physical parameter of the coarse tuner is adapted to be set to achieve coarse impedance matching between the microwave generator and the plasma generated during both the plasma ignition process and the steady state process. A load impedance of the plasma generated during the plasma ignition process and the steady state process is adapted to vary. The microwave generator is configured to tune an operating frequency at the set physical parameter of the coarse tuner.

摘要： Inductively coupled plasma (ICP) analyzers use an ICP torch to generate a plasma in which a sample is atomized an ionized. Analysis of the atomic ions can be performed by atomic analysis, such as mass spectrometry (MS) or atomic emission spectrometry (AES). Particle based ICP analysis includes analysis of particles such as cells, beads, or laser ablation plumes, by atomizing and ionizing particles in an ICP torch followed by atomic analysis. In mass cytometry, mass tags of particles are analyzed by mass spectrometry, such as by ICP-MS. Systems and methods of the subject application include one or more of: a demountable ICP torch holder assembly, an external ignition device; an ICP load coil comprising an annular fin, particle suspension sample introduction fluidics, and ICP analyzers thereof.

摘要： A plasma torch employs a dielectric resonator excited at separate locations with phase shifted signals to provide more uniform current flow through the resonator. High-power operation is possible while protecting the dielectric by using a combination segregated spiral flow and linear flow cooling air at different rates. Microwave leakage from the plasma resonant chamber is contained by conductive metal chokes.
