We study the optimal temperature to obtain YBa2Cu3O7-δ epitaxial films grown onto SrTiO3 substrates by direct solution deposition. The samples received heat treatment at 820, 840 and 860 °C, then characterized by XRD, observing the (00l) profiles; and magnetic susceptibility measurements. The TC-onset for all the samples was 90 K. In addition, the current – voltage (I-V) measurements shows typical tunneling signals corresponding to normal metal-superconducting junctions indicating the films are promising for potential electrical applications.

The identification of geological sources of obsidians collected in archaeological sites provides important information about circulation routes and sociocultural relationships during prehistoric periods. This paper presents the preliminary results obtained by MS and EPR on geological obsidians from Ayacucho and Arequipa, in Peru and on archaeological obsidian artifacts from Cerrillos, an early Paracas site of the upper Ica valley, south of Lima (Peru).
