Se presentan los primeros resultados analíticos del oro del Tesoro visigodo de Guarra/ar (Guadamur. Toledo) enmarcado en un proyecto para caracterizar estas producciones orfebres y su nivel tecnológico. Así mismo, se pretende acla rar ciertos aspectos sobre su estado actual, como las asociaciones entre materia les o la identificación de partes...

This paper is focused on the sputtering process and on the structure, chemical composition and mechanical properties of coatings consisting of Al\O dielectric matrix incorporated with increasing Au contents. The maximum Au content incorporated in the coatings was 9 at.%. Al was in deficient values in relation to the Al2O3 compound. Al\O matrix...

In the present study, nanocomposite coatings of Au clusters embedded in two different oxides, TiO2 and Al2O3, were synthesized using pulsed DC magnetron sputtering. The depositions were carried out in three steps, by depositing the oxide, the Au clusters, and again the oxide. The deposition time of the Au clusters was varied in order to achieve...

In this work, we address the capability of glow discharge optical emission spectroscopy (GDOES) for fast and accurate depth profiling of multilayer nitride coatings down to the nanometer range. This is shown by resolving the particular case of CrN/AlN structures with individual thickness ranging from hundreds to few nanometers. In order to...
