Abstract:
A non-thermal atmospheric pressure plasma reactor including a primary dielectric having at least one slit defined therein and a segmented electrode including a plurality of electrode segments. Each electrode segment disposed proximate and in fluid communication with an associated slit. The slit in the dielectric may be formed in any number of ways such as a plurality of slits defined in a substantially planar dielectric plate. Other configurations include a plurality of dielectric segments (e.g., bars, slabs, rings, annular sections) assembled together so that a slit is formed between adjacent dielectric segments. In operation a voltage differential is applied between the segmented electrode and a receiving electrode disposed proximate the primary dielectric to produce a plasma discharge. The plasma discharge is emitted through the slits in the primary dielectric. This inventive plasma discharge device configuration produces a relatively high density non-thermal plasma discharge of relatively large volume yet is relatively easy and inexpensive to manufacture.
Abstract:
Inventive methods and apparatus are useful for collecting magnetic materials in one or more magnetic fields and resuspending the particles into a dispersion medium, and optionally repeating collection/resuspension one or more times in the same or a different medium, by controlling the direction and rate of fluid flow through a fluid flow path. The methods provide for contacting derivatized particles with test samples and reagents, removal of excess reagent, washing of magnetic material, and resuspension for analysis, among other uses. The methods are applicable to a wide variety of chemical and biological materials that are susceptible to magnetic labeling, including, for example, cells, viruses, oligonucleotides, proteins, hormones, receptor-ligand complexes, environmental contaminants and the like.

Abstract:
Disclosed is a rotational laser apparatus capable of setting an obliquity without requiring a high accuracy light receiver or a complex optical system for separating different polarized fluxes. The rotational laser apparatus comprises a plurality of reflected sections provided on a target in a direction transverse to scanning laser beam. The reflected planes is disposed in such a manner that a time series arranging state for pulses of the light receiving signal differs between a case that the scanning laser beam intersects the reflected sections from one side to the other side and a case that the laser beam intersects the reflected sections from the other side to one side, with identical scanning direction of the scanning laser beam, The control part includes a judging circuit for judging an operated direction of the oblique mechanism based on the time series arranging state for pulses of the light receiving signal.

Abstract:
A fluid treatment system consists of a light source for providing light and a flexible treatment chamber having an input port and an output port, at least a portion of the flexible treatment chamber positioned to receive the light. The at least the portion of the flexible treatment chamber is transmissive to at least 1% of the light having at least one wavelength within a range of 170 to 2600 nm and the flexible treatment chamber is adapted to allow a fluid to be treated to be flowed via the input port therethrough at a specified rate and out the output port. The light source illuminates the fluid as it flows through the flexible treatment chamber in order to deactivate pathogens within the fluid. In some embodiments, the light source is a pulsed light source for emitting short duration, pulses of polychromatic light.

Abstract:
The present invention is a method and apparatus for altering a carbon-containing compound in an aqueous mixture. According to a first aspect of the present invention, it has been discovered that for an aqueous mixture having a carbon containing compound with an ozone reaction rate less than the ozone reaction rate of pentachlorophenol, use of corona discharge in a low or non-oxidizing atmosphere increases the rate of destruction of the carbon containing compound compared to corona discharge an oxidizing atmosphere. For an aqueous mixture containing pentachlorphenol, there was essentially no difference in destruction between atmospheres. According to a second aspect of the present invention, it has been further discovered that an aqueous mixture having a carbon-containing compound in the presence of a catalyst and oxygen resulted in an increased destruction rate of the carbon containing compound compared to no catalyst.
Abstract:
Methods of using ozone have been developed which sterilize instruments and medical wastes, oxidize organics found in wastewater, clean laundry, break down contaminants in soil into a form more readily digested by microbes, kill microorganisms present in food products, and destroy toxins present in food products. The preferred methods for killing microorganisms and destroying toxins use pressurized, humidified, and concentrated ozone produced by an electrochemical cell.
