Several strains of a streptomycete with unusual spore wall ornamentation were isolated from Iowa soils. They are further characterized by coiled chains of spores, gray aerial mycelium, melanin-like pigments, and the production of antibacterial and antifungal antibiotics. Spore wall ornamentations, as seen with the transmission electron microscope, do not correspond with any of the four generall...

cofe2o4 magnetic nano particles (mnps) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. then, a hybrid nanocomposite of polyaniline (pani)-cofe2o4 mnps has been electrodeposited directly on a stainless steel wire by the potentiostatic method. microscopic images of electrodeposited pani and pani-cofe2o4 nanocomposite coatings were obtained by s...
