    摘要： A method and apparatus for the pyrolytic destruction or synthesis of gases via a highly tunable combination of radio frequency heating and electron beam irradiation is disclosed. The method is appropriate for destroying toxic gases emanating from hazardous wastes and for synthesizing new molecules from the molecules of a gas. The method is also appropriate for creating scavenger gases and hot gases with large enthalpy for use in sterilization procedures, for example. Embodiments are disclosed employing inductive or direct waveguide/cavity coupling of radio frequency power to the gas. In embodiments of the invention, magnetic fields are used to modify the paths of the electrons in the beam to facilitate tuning and improve the energy efficiency of the system. In a two-stage system, solid and/or liquid wastes are first heated in order to vaporize the toxic materials. Then, the gases produced in the first stage are destroyed by the combination of radio frequency heating and electron beam irradiation of the invention.

    摘要： A system and method is provided for increasing interaction between seed particles in a seed cloud and target particles to be neutralized, detected or knocked down to the ground. This is achieved by applying a charge to the seed particles so that the seed cloud formed by release of the seed particles at altitude is highly charged, which in turn produces a strong electric field between the seed cloud and ground. The relatively strong electric field causes the seed particles to move downward (toward the ground) at a velocity sufficient to increase interaction (collisions) between the seed particles and the target particles.

    摘要： A system for decontaminating the contaminated fluid by using photocatalytic particles. The system includes a reactor tank for holding the contaminated fluid and the photocatalytic particles suspended in the contaminated fluid to form a slurry. Light irradiates the surface of the slurry, thereby activating the photocatalytic properties of the particles. The system also includes stirring blades for continuously agitating the irradiated fluid surface and for maintaining the particles in a suspended state within the fluid. The system also includes a cross flow filter for segregating the fluid (after decomposition) from the semiconductor powder. The cross flow filter is occasionally back flushed to remove any semiconductor powder that might have caked on the filter. The semiconductor powder may be recirculated back to the tank for reuse, or may be stored for future use. A series of such systems may be used to gradually decompose a chemical in the fluid. Preferably, the fluid is pretreated to remove certain metal ions which interfere with the photocatalytic process. Such pretreatment may be accomplished by dispersing semiconductor particles within the fluid, which adsorb ions or photodeposit the metal as the free metal or its insoluble oxide or hydroxide, and then removing the semiconductor particles together with the adsorbed metal ions/oxides/hydroxide/free metal from the fluid. A method of decontaminating a contaminated fluid is also disclosed.
