Abstract: A process comprises feeding a stream of reactant compounds to a reactor and discharging a liquid plasma into the reactant stream in the reactor, wherein the plasma initiates or accelerates a reaction of the reactant compounds to form a product composition. The reactor can comprise one or more chambers, a high-voltage electrode positioned at a first portion of the one or more chambers, a ground electrode positioned at a second portion of the one or more chambers, and a dielectric plate between the ground electrode and the high-voltage electrode that comprises openings through which the reactant stream can pass from the first portion to the second portion or from the second portion to the first portion. Discharging the plasma can include supplying electrical power to the high-voltage electrode such that plasma is discharged where the reactant stream flows through the openings.

Abstract: A system and method are provided for the separation of hydrogen from natural gas feedstock to form hydrocarbon radicals. Aspects of the system include perpendicular magnetic and electric fields, a method of radical formation that separates hydrogen from the reaction process, and a separation method based on centrifugal forces and phase transitions. The gases rotate in the chamber due to the Lorentz force without any mechanical motion. Rotation separates gases and liquids by centrifugal force. The lighter species are collected from the mid region endpoint of the apparatus and fed back for further reaction. A new concept of controlled turbulence is introduced to mix various species. A novel magnetic field device is introduced comprised of two specially magnetized cylinders. A novel control of temperatures, pressures, electron densities and profiles by, RF, microwaves, UV and rotation frequency are possible especially when atomic, molecular, cyclotron resonances are taken into account. The electrodes can be coated with catalysts; the entire apparatus can be used as a new type of chemical reactor.

Abstract: A system and method for controlling microbial growth on and in medical devices and implants, especially biofilm infections, involves using pulsed electric fields (PEF). To eradicate at least a portion of a biofilm on a medical implant, for example, 1500 volts can be applied through an electrode system, with pulse duration of 50 μs and pulse delivery frequency of 2 Hz. In the clinical setting, systemic microbial therapy can be combined with PEF to achieve a synergistic effect leading to improved eradication of infections.

Abstract: System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.
