in the study of the effects of salicylate on population density of naphthalene degrading bacteria and heterotrophic bacteria in a sample or: soil polluted with aromatic hydrocarbons, two different concentrations of salicylate (16, 160) ?g / gr of soil incubated for 30 days. at 160 ?g / gr, salicylate enhanced the density of naphthalene degraders and heterotrophic bacteria for 30 days. no chenge...

For photovoltaic applications, microcrystalline silicon has a lot of advantages, such as the ability to absorb the near-infrared part of the solar spectrum. However, there are many dangling bonds at the grain boundary in microcrystalline Si. These dangling bonds would lead to the recombination of photo-generated carriers and decrease the conversion efficiency. Therefore, we included the grain b...

Hybrid halometalates containing lead, tin, bismuth and antimony organic cations have recently shown a bevy of interesting photophysical properties. Aiming at finding chemically stable thermally inert species, three halobismutate species this class, crystallized with proton sponge-derived (PRSH), been isolated as microcrystalline powders by mixing 1,8-bis(dimethylamino)-naphthalene (proton spong...

The marine cyanobacterium Oscillatoria sp. strain JCM oxidized naphthalene predominantly to 1-naphthol. Experiments with [1-2H]naphthalene and [2-2H]naphthalene indicated that 1-naphthol was formed with 68 and 74% retention of deuterium, respectively. No significant isotope effect was observed when the organism was incubated with a 1:1 mixture of naphthalene and [2H8]naphthalene. The results in...

Over fifty bacterial strains were isolated from seawater samples in the presence of naphthalene as a sole source of carbon and energy. Among them, three isolates with higher growth rate and naphthalene degradation ability were selected for further studies. Biochemical and molecular analysis revealed that two Persian Gulf isolates, strain PG-10 and strain PG-48 belonged to the group of hydrocarb...
