A device for obtaining and applying a disinfectant agent and method of use are provided. The device includes a pre-processing cascade unit that activates (ionizes) air, with the activated air being supplied by an air pump to an inlet of a sprayer, where the activated air mixes with an initial working fluid (distilled water) to form an activated air-working fluid aerosol mixture that is sprayed by the sprayer into a reactor of cone-shaped volumetric cold plasma that includes divergent discharge electrodes. The device further includes a unit for generating high-voltage pulses of a nanosecond duration that is connected to the discharge electrodes and that causes the electrodes to generate electrical discharges. Upon the mixture coming into contact with the electrical discharges, potent disinfectant agents (such as peroxynitrite and one or more peroxynitrite's precursors or derivatives) are synthesized and expelled from the device.

A methane (CH.sub.4) gas is synthesized from carbon dioxide (CO.sub.2) and hydrogen (H.sub.2) using catalyst-dielectric barrier discharge (DBD) plasma at room temperature and atmospheric pressure. In the method and apparatus for synthesizing methane gas of the invention, methane (CH.sub.4) gas, which is synthetic natural gas, can be effectively synthesized only from carbon dioxide (CO.sub.2) and hydrogen (H.sub.2) using DBD plasma at room temperature and atmospheric pressure, and also, additional heating and pressurization devices are not used during the methane gas synthesis process, thus reducing production costs and realizing high-value-added processing due to the absence of risks during the processing.

A method for bonding a fluid to a substance includes filling a first pressure vessel with the fluid and pressurizing the first pressure vessel to a first pressure. The fluid is the circulated through an electric arc formed within the first pressure vessel, thereby creating a treated fluid. Within a second pressure vessel, the substance is exposed to a magnetic field, thereby forming a polarized substance. The treated fluid and polarized substance are combined under a second pressure within a third pressure vessel, thereby exposing the treated fluid to the polarized substance at a pressure sufficient to achieve a bond.
