Synthetic Approaches

ABSTRACTSemiconductor nanoparticulates are important materials bridging the gap in size and electronic properties between molecular species and bulk materials. Synthetic approaches to producing controlled sized clusters of this sort will be described, covering physical encapsulation in zeolites or porous glass and extending to discrete syntheses using surface terminating reagents. The optical properties of the resultant materials will be described in detail and the structural topology of the clusters elucidated by combined powder and single crystal diffraction. Thermal transformations of these clusters into bulk materials will be tracked and the processing possibilities explored for the production of polycrystalline films and polymer/semiconductor composites. Photoconductivity in the latter composites will be described.

Stainless Steel Aisi

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.
