Transparent metal oxide thin films of samarium oxide (Sm2O3) were prepared on pre-cleaned fused optically flat quartz substrates by radio-frequency (RF) sputtering technique. The as-deposited thin films were annealed at different temperatures (873, 973 and 1073 K) for 4 h in air under normal atmospheric pressure. The topological morphology of the film surface was characterized by using atomic force...
Pyridopyrimidine derivatives , and were furnished by the reaction of compound with a variety of reagents, namely, formic acid, acetic anhydride, phenyl isothiocyanate, phenyl isocyanate, carbon disulfide, acetamide and thioacetamide, which in turn were treated with hydrazine to give pyrazolopyridopyrimidine derivatives , and . The potency of the results as antibacterial agents has been evaluated...
