  • Patent number: 10692704
    Abstract: Exemplary systems and methods associated with activating fluids using indirect plasma. In particular, liquid can be activated to high concentrations and at high volumes by thinning and mixing the liquid as it is exposed to the plasma, resulting more efficient activation. Further increases in activation can be reached by re-circulating fluid for additional exposure to the plasma. High flow rates can be achieved with integrated systems that utilize multiple activation systems with coordinated control.

Electrodes are arranged with respect to the microcavities or microchannels to stimulate plasma generation therein upon application of suitable voltage. One or more or all of the electrodes are encapsulated within the thick metal oxide layer. A gas inlet is configured to receive feedstock gas into the plurality of microcavities or microchannels. An outlet is configured to outlet reactor product from the plurality of microcavities or microchannels. In an example preferred device, the feedstock gas is air or O2 and is converted by the plasma into ozone (O3). In another preferred device, the feedstock gas is an unwanted gas to be decomposed into a desired form. Gas reactor devices of the invention can, for example, decompose gases such as CO2, CH4, or NOR.

  • Patent number: 9011698
    Abstract: A method and devices comprise a low frequency high energy ultrasound system having at least one sonotrode projecting into a reactor vessel through which the liquid passes via at least one inlet orifice and at least one outlet orifice. To avoid cavitation at the sonotrode, in a close region of the oscillation-transducing sonotrode surface a pressure/amplitude combination close to or above the pressure-amplitude characteristic line is generated at which considerably reduced or no cavitation occurs and in the adjacent region in the vessel at least in a region and at least at times a pressure/amplitude combination is maintained below the pressure-amplitude characteristic line at which cavitation is generated. A device has an inlet orifice arranged such that the liquid impacts directly onto the oscillation-transducing sonotrode surface, and is shaped that in the close region of the oscillation-transducing sonotrode surface a pressure close to or above the pressure-amplitude characteristic line prevails.

  • Publication number: 20150093453
    Abstract: This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s).
