    摘要： An improved method for charging ultrafine particles in coronas (e.g., unipolar or bipolar corona discharges) by exposing the particles to X-ray irradiation. Experimental tests have verified that positive corona in the presence of X-ray irradiation results in maximum or optimum charging efficiency, followed by a negative corona in the presence of X-ray irradiation, X-ray radiation only (without corona), negative corona only (without X-ray irradiation), and finally positive corona only (without X-ray irradiation). This method and system is particularly well suited for use with bioaerosol particles wherein exposure to the corona discharge and X-ray irradiation serves to both capture and inactivate the bioaerosol particles using a single device.

    摘要： An improved process for the preparation of nanostructured metal species-based films in a flame aerosol reactor is provided. The process comprises combusting vaporized metal precursor, vaporized fuel and vaporized oxidizer streams to form metal species-based nanoparticles in a flame that are deposited onto a temperature controlled support surface and sintered to form the metal species-based nanostructured film. Improved nanostructured photo-watersplitting cells having a sunlight to hydrogen conversion efficiency of from about 10% to about 15%, dye sensitized solar cells having a sunlight to electricity conversion efficiency of from about 10% to about 20%, and nanostructured p/n junction solar cells having a sunlight to electricity conversion of from about 10% to about 20% are provided. Each cell type comprises a nanostructured metal oxide film having continuous individual columnar structures having an average width (w) and grain size criterion (X3) wherein w/10 is greater than X3.
