  • Aquifer storage and recovery system including aerobic reactor using microbes from underground aquifer
    Patent number: 10745306
    Abstract: Provided is an aquifer storage and recovery system, in which microbes extracted from an underground aquifer are involved in an assimilable organic carbon (AOC) removal mechanism and applied to an aerobic reactor, and a predetermined portion of assimilable organic carbon in raw water is removed through the aerobic reactor.
    Type: Grant
    Filed: April 22, 2019

  • Micro sensor arrays for in situ measurements
    Publication number: 20070003209
    Abstract: A method is provided for fabricating microelectrodes and microelectrode arrays by etching in an acid solution. Glass wafers are diced into a desired shape to form narrow probes, which are immersed in the acid solution. An organic layer on top of the acid solution forms a meniscus at the point of contact with the probes, and the taper angle on the etched probes will depend on this meniscus angle. After etching, the tapered probes are coated with a conductive layer, followed by an insulating layer over most of their length so as to leave a small conductive area exposed at the tip. The glass wafer containing the probes is then mounted on a printed circuit board carrier.
