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). Results include constituents formed in the liquid including micron-sized particles and/or nanoparticles (e.g., metallic-based nanoparticles) of novel size, shape, composition and properties present in a liquid.

The present invention provides system, method and apparatus for creating an electric glow discharge that includes a first and second electrically conductive screens having substantially equidistant a gap between them, one or more insulators attached to the electrically conductive screens, and a non-conductive granular material disposed within the gap. The electric glow discharge is created whenever: (a) the first electrically conductive screen is connected to an electrical power source such that it is a cathode, the second electrically conductive screen is connected to the electrical power supply such that it is an anode, and the electrically conductive fluid is introduced into the gap, or (b) both electrically conductive screens are connected to the electrical power supply such they are the cathode, and the electrically conductive fluid is introduced between both electrically conductive screens and an external anode connected to the electrical power supply.

The outer diameter measures at most 20 mm in the terminal region towards the longitudinal axis.

A laser irradiation apparatus may include a plasma generator, a laser unit configured to output a pulsed laser light beam, and a controller. The plasma generator may be configured to supply an atmospheric pressure plasma containing a dopant to a predetermined region on a semiconductor material. The controller may be configured to control the plasma generator and the laser unit to perform one of first and second controls to thereby perform doping of the dopant into the semiconductor material. The first control may cause irradiation of the predetermined region with one or more pulses of the pulsed laser light beam from start to finish of supply of the atmospheric pressure plasma to the predetermined region. The second control may cause irradiation of the predetermined region with one or more pulses of the pulsed laser light beam after supply of the atmospheric pressure plasma to the predetermined region.

A cold plasma jet hand sanitizer and method of use are provided. A pair of opposing two-dimensional arrays of atmospheric pressure cold plasma jets is used to create a sterilizing volume. Any object placed into that volume will have its surface sterilized. The opposing arrays of plasma jets are operated electrically 180 degrees out of phase so that the opposing arrays of plasma jets essentially fire into each other in the absence of an intervening object, or directly impinge on the surface of an intervening object.

A method for manufacturing metal powder includes: melting at least a portion of a metal starting material in a reaction vessel by utilizing plasma so as to form molten metal; evaporating the molten metal so as to produce a metal vapor; and transferring the metal vapor from the reaction vessel to a cooling tube together with a carrier gas supplied into the reaction vessel so as to cool the metal vapor, and condensing the metal vapor in the cooling tube, thereby producing metal powder. The method further includes supplying an oxygen gas into the reaction vessel.

An apparatus for generating a flow of reactive gas for decontaminating a material, surface or area, comprises a first electrode member comprising a first plurality of conductive surfaces and a second electrode member comprising a second plurality of conductive surfaces. The second electrode member is arranged in spaced relationship with the first electrode member to define a reactor channel. The conductive surfaces are exposed to the reactor channel so as to form air gaps between the first plurality of conductive surfaces and the second plurality of conductive surfaces. An air blower generates a flow of air through the reactor channel. An electric pulse generator repetitively generates voltage pulses between the first and second electrode members so as to produce glow discharges in the air gaps between the conductive surfaces of the first plurality and the conductive surfaces of the second plurality, the voltage pulses being generated at time intervals less than 1 millisecond and voltage pulse duration less than about 500 ns, the glow discharges being adapted to transform part of the flow of air into reactive gas. An output section delivers the reactive gas from the reactor channel to a sample or region to be decontaminated or treated.

An air purification device and an air conditioner are provided. The air purification device includes a housing and an ion generation assembly. The housing includes a protective cover and a base connected to each other. The ion generation assembly includes at least one first electrode, a second electrode and a third electrode. The first electrode is used for discharging to generate negative ions, and the second electrode and the third electrode are spaced apart and used for generating plasma cooperatively. The protective cover is of a hollowed-out structure covering the ion generation assembly. The first electrode and the second electrode are connected to the base, and the third electrode is connected to the inner side of the protective cover.

A plasma generated by a plasma generator is used to activate a fluid in a variety of ways to generate a plasma activated liquid or gas. The plasma generator may be controlled to optimize, such as maximize, a radical concentration in the plasma activated liquid or gas. The plasma activated fluid may be applied to various items, surfaces, and/or added to fluid volumes to affect chemical specifies and organism therein.
