Abstract. Bi2O3 nanofibers with diameter of 70–200 nm were successfully prepared by electrospinning a precursor mixture of polyacrylonitrile (PAN)/bismuth nitrate, followed by calcination treatment of the electrospun polymer/inorganic composite fibers. The resulting Bi2O3 nanofibers were characterized with X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, …
Field measurements in rural households were conducted in three Chinese municipalities/provinces (Beijing, Chongqing, and Henan) to determine the emission characteristics of particulate matter from biofuel combustion. The selected biofuel types and stove types are representative of local rural areas. Particle number concentration, size distribution, and mass size distribution were determined. B…
