Abstract

Systems and methods configured to produce electrical discharges in compositions, such as those, for example, configured to produce electrical discharges in compositions that comprise mixtures of materials, such as a mixture of a material having a high dielectric constant and a material having a low dielectric constant (e.g., a composition of a liquid having a high dielectric constant and a liquid having a low dielectric constant, a composition of a solid having a high dielectric constant and a liquid having a low dielectric constant, and similar compositions), and further systems and methods configured to produce materials, such as through material modification and/or material synthesis, in part, resulting from producing electrical discharges in compositions.

First claim

The invention claimed is:

1. A system for producing a voltage difference comprising:
a container comprising a liquid having a low dielectric constant and either a liquid having a high dielectric constant or a solid having a high dielectric constant;
a plate electrode disposed in the liquid in the container and coupled to a power supply; and
a gas supply system coupled to the power supply, the gas supply system comprising: a first gas pipe and a second gas pipe,
the first gas pipe comprising: a first end disposed in the liquid of the container and having an opening; a second end coupled to a gas source; and a bore extending through the second end and the first end and enabling gas from the gas source to be passed through the bore of the first gas pipe and into the liquid of the container;
the second gas pipe comprising: a first end disposed in the liquid of the container and having an opening; a second end coupled to the gas source; and a bore extending through the second end and the first end and enabling gas from the gas source to be passed through the bore of the second gas pipe and into the liquid of the container;
where the first gas pipe is disposed at least partially within the bore of the second gas pipe such that a channel is formed between the first gas pipe and the second gas pipe; and
where the electrode and the first ends of the first and second gas pipes are disposed in the liquid such that a voltage difference between at least a portion of the gas supply system and the electrode is produced when the power supply is activated.

2. The system of claim 1 , where the container comprises the liquid having a high dielectric constant.

3. The system of claim 2 , where the liquid having a low dielectric constant is an organic liquid with a low dielectric constant, and the liquid having a high dielectric constant is selected from the group consisting of an organic liquid with a high dielectric constant and water.

4. The system of claim 1 , where the container comprises the solid having a high dielectric constant.

5. The system of claim 4 , where the liquid having a low dielectric constant is an organic liquid with a low dielectric constant, and the solid having a high dielectric constant is a packed solid.

6. The system of claim 5 , where the packed solid comprises cylindrical, rectangular, or spherical shaped solids.

7. The system of claim 4 , where the solid comprises titanium dioxide, strontium titanate, barium titanate, lead zirconium titanate, or calcium copper titanate.

8. The system of claim 4 , where the solid comprises a packed solid.

9. The system of claim 8 , where the packed solid comprises cylindrical, rectangular, or spherical shaped solids.

10. The system of claim 8 , where the packed solid contacts the first end of the second gas pipe.

11. The system of claim 1 , where the first end of the first gas pipe comprises a shape enabling production of a nonuniform electrical field between the gas supply system and the electrode when the power supply is activated.

12. The system of claim 11 , where a portion of a width of the first gas pipe narrows from the second end to the first end.

13. The system of claim 12 , where the first end of the first gas pipe is pointed.

14. The system of claim 1 , where the container is electrically insulated.

15. The system of claim 1 , where the electrode comprises copper alloy, graphite, steel, stainless steel, tungsten, or platinum.

16. The system of claim 1 , where the gas supply system is configured to produce bubbles in the liquid in the container between the electrode and the gas supply system.

17. The system of claim 1 , where the power supply is a pulsed power supply.

18. The system of claim 1 , where the second end of the second gas pipe is coupled to the gas source at two locations.

19. The system of claim 1 , where the gas supply source comprises at least one gas selected from the group consisting of hydrogen, helium, carbon dioxide, helium, a noble gas, argon, oxygen, hydrocarbon gas, nitrogen, and combinations thereof.
