Spectroscopic Characterization Technical High Resolution of Gold from a Memory Card RAM

Traditionally, materials characterization instrumentation has focused mainly on particles. However, for a better fundamental understanding and various potential applications, it requires an increase in the ability of instrumentation to observe.Characterization and manipulation requires not only extreme sensitivity and accuracy, but also atomic level resolution. In this regard, it is noteworthy the importance of the central role that the various modes of microscopy play in materials characterization and measurement.Also, are particularly relevant physical properties and short-range forces, but do not play a prominent role in the characterization at the macroscopic level, represent a significant impact on the nanometer scale.The sample is studied, are the connections of the RAM, from an IBM 450.The sample characterization was performed at the scanning electron microscope of the Research center in Engineering and Applied Sciences (CIICAp) of the Autonomous University of the State of Morelos (UAEM), is observed in the presence concentrate gold, nickel and carbon.In the scanning electron microscope has the research center, we have observed the presence of gold particles included in the RAM, the particles represent 90.20% by weight, there are also carbon particles containing nickel and 1.94 and 7.86 wt% respectively.
