First, as an analogue of Dowker's theorem for countable paracompactness, we prove a characterization of countable metacompactness in terms of subnormality of products. Second, as an analogue of Tamano's theorem for paracompactness, we give a characterization of Lindelijfness in terms of normality of

A new type of carbon nanotube (CNT) (diameter of ฯฝ100 nm) coated by conducting polypyrrole (PPY) was synthesized by in situ polymerization on CNTs. The structure of the resulting complex nanotubes (CNT-PPY) was characterized by elemental analysis, X-ray photoelectron spectroscopy, Raman spectra, and
