To provide a reactor to improve evenness in the thickness of shell metals coated on the surface of core particles by increasing area sizes in the reactor chamber to control electric potentials, the present invention is configured to comprise a top surface able to move up and down while serving as a working electrode, a wall serving as a working electrode, a bottom surface, a standard electrode, a power supplying part and a solution injecting part, wherein the top surface can move up and down automatically by an electric motor or manually. Also, the top surface is configured to be suitable for the interior diameter of the reactor chamber, for solutions inside the reactor chamber not to leak from the top surface or from the crevice between the top surface and the wall of the reactor chamber. The bottom surface of the reactor chamber may comprise an impeller or an ultrasonic wave diffuser to bring about even diffusion in the reactor chamber.

A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.

Methods and apparatus for producing chemical nanostructures having multiple elements, such as boron and nitride, e.g. boron nitride nanotubes, are disclosed. The method comprises creating a plasma jet, or plume, such as by an arc discharge. The plasma plume is elongated and has a temperature gradient along its length. It extends along its length into a port connector area having ports for introduction of feed materials. The feed materials include the multiple elements, which are introduced separately as fluids or powders at multiple ports along the length of the plasma plume, said ports entering the plasma plume at different temperatures. The method further comprises modifying a temperature at a distal portion of or immediately downstream of said plasma plume; and collecting said chemical nanostructures after said modifying.

A water treatment device includes a grounding electrode having a planar flowing water portion that causes treatment target water to flow, a multiple of wire form high voltage electrodes provided parallel with the flowing water portion in a position distanced from the flowing water portion of the grounding electrode and to extend in a direction intersecting a flow direction of the treatment target water, and a blowing device that forms a gas flow that intersects an extension direction of the high voltage electrode and intersects an extension direction of an electrical discharge. This kind of configuration is such that even when water droplets adhere to the high voltage electrode, the water droplets are blown away by a pressure of the gas flow formed by the blowing device, and a spark discharge is restricted.
