    摘要: A high efficiency plasma activation system for large scale treatment of liquid including a liquid tank; a pump having an inlet fluidly connected to an outlet of the liquid tank; a self-suction mechanism having a liquid inlet fluidly connected to an outlet of the pump, an air inlet, and an outlet fluidly connected to an inlet of the liquid tank; and a plasma generator having a plasma discharge nozzle positioned adjacent to the air inlet of the self-suction mechanism and configured to discharge gas phase plasma into the air inlet of the self-suction mechanism and introduce micro/nano bubbles (MNBs) into a flow of liquid to be treated to where the MNBs collapse to agitate and impregnate the liquid with a gas, for highly efficient plasma activation of liquid on a large scale as a green and sustainable technology for disinfection in the food industry and agriculture.

    摘要: A filter for mimicking regional lung deposition is provided that includes filter layers of fibrous filter material stacked coaxially and an outer ring portion encircling the fibrous filter material and securing the filter layers together. The fibrous filter material is formed for fibers having a fiber diameter, and the filter has a tunable filter efficiency. A regional lung deposition system capable of measuring constant flow or variable flow is provided that includes a throat simulation device, a filter housing downstream of and in fluid communication with the throat simulation device, a breath simulator downstream of and in fluid communication with the filter housing, and a an above-referenced filter positioned within the filter housing. Also provided is a filter housing for use in the regional lung deposition system that includes a conical housing having a small inner diameter at a first end and a large inner diameter at a second end.
