Schiff base oligomers obtained by self-condensation from monomers containing simultaneously amino and aldehyde groups are rare in the literature. Novel conjugated oligomers were synthesized by self-condensation of 5-(4-aminophenyl) aryl-2-carboxaldehyde prepared in situ from the corresponding nitro homologous compounds. The oligomers were characterized by spectroscopic methods. Band gap and absorption...
The development of mixed-oxide thin films allows obtaining materials with better properties than those of the different binary oxides, which makes them suitable for a great number of applications in different fields, such as tribology, optics or microelectronics. In this paper we investigate the deposition of mixed chromium and silicon oxides deposited by reactive magnetron sputtering with a view...
