Abstract:
Apparatus and methods according to the present invention preferably utilize electroosmotic pumps that are capable of generating high pressure and flow without moving mechanical parts and the associated generation of unacceptable electrical and acoustic noise, as well as the associated reduction in reliability. These electroosmotic pumps are preferably fabricated with materials and structures that improve performance, efficiency, and reduce weight and manufacturing cost relative to presently available micropumps. These electroosmotic pumps also preferably allow for recapture of evolved gases and deposited materials, which may provide for long-term closed-loop operation. Apparatus and methods according to the present invention also allow active regulation of the temperature of the device through electrical control of the flow through the pump and can utilize multiple cooling loops to allow independent regulation of the special and temporal characteristics of the device temperature profiles. Novel microchannel structures are also described.
Abstract:
By focusing on the fact that nitrogen dioxide exhibits an increased sterilizing effect among other sterilant gases including nitrogen oxide, the present invention is made to provide a sterilization method which may be suitably used for sterilizing items to be sterilized such as medical instruments which require increased reliability by using a high concentration NO2 gas of 5,000 ppm or above, for example. An inside of a sterilizing chamber containing an item to be sterilized is humidified, and a concentration of NO2 in the sterilizing chamber is made to be from 9 to 100 mg/L by filling a high concentration NO2 gas.
Abstract:
A high concentration NO2 gas generating system including a circulating path configured by connecting a chamber, a plasma generator, and a circulating means, wherein NO2 is generated by circulating a gas mixture including nitrogen and oxygen in the circulating path is provided. The high concentration NO2 gas generating system provides a high concentration NO2 generating system and the high concentration NO2 generating method using the generating system by which NO2 of high concentration (approximately 500 ppm or above) required for a high level of sterilization process in such as sterilization of medical instruments can be simply and selectively obtained. In addition, since indoor air is used as an ingredient, the management of ingredients is simple and highly safe, and the high concentration of NO2 can be simply and selectively prepared on demand.

Abstract:
Systems for generating microwave plasma from a combustion flame. The present invention provides a microwave plasma nozzle that includes a hollow cylindrical housing through which combustible material flows, and a rod-shaped conductor disposed in the housing. A portion of the rod-shaped conductor extends into a microwave cavity to receive microwaves passing in the cavity. The rod-shaped conductor transmits microwaves along the surface thereof, and has a distal end disposed in proximity to and surrounded by a proximal end portion of the housing. During operation, a combustion flame is formed in proximity to the proximal end portion of the housing, and the microwaves transmitted along the surface heat up the flame to generate plasma in proximity to the distal end of the rod-shaped conductor.
