Abstract Continuing the research in the field of complex compounds, the authors present in this paper the synthesis and characterization of a new compound of Cu(II) with the ligand 1-(3 bromo, 2 hydroxy, 4 methyl-phenyl)-2-(4 bromophenyl- sulphanyl)-etanone. Different methods were used, such as chemical elemental analysis, thermal-gravimetry, infrared absorption spectroscopy and electronic spin resonance (ESR). From chemical analysis resulted that the combination ratio ligand-central atom is 2:1. The new compound can also be used for gravimetric determination of Cu(II).

The synthesis and characterization of Ti and TiN thin films of different thicknesses was carried out on a martensitic stainless steel AISI 410 substrate used for tool manufacturing. The mechanical parameters between the interacting surfaces such as thickness, adhesion and hardness were measured. By means of the scanning electron microscope (SEM) the superficial morphology of the Ti/TiN interface was observed, finding that the growth was of columnar grains and by means of EDAX the existence of titanium was verified.  Using X-ray diffraction (XRD) it was possible to observe the presence of residual stresses (~ -3.1 GPa) due to the different crystalline phases in the coating. Under X-ray photoemission spectroscopy (XPS) it was possible to observe the molecular chemical composition of the coating surface, being Ti-N, Ti-N-O and Ti-O the predominant ones.
