A new class of hybrid ruteno-cuprates – such as Ru-1212 and Ru-1222 – was discovered in 1995 by Bauerfeind and collaborators. These materials present superconducting and magnetic states at low temperatures, an atypical duality in other superconductors. The superconductivity is more easily observed in Ru-1222, while Ru-1212 is a more problematic case, due to the strong effects of the preparation details in its superconducting properties, becoming the material superconductor or not. Ru-1212 presents a critical temperature that can vary between 0 and 46 K, depending on the preparation conditions, and a temperature of magnetic transition of around 132 K. The samples were prepared through solid state reactions, by using a mixture of high purity powders, followed by calcination and sinterization in the nitrogen and oxygen atmospheres. This paper shows the preparation process of Ru-1212 samples, followed by their structural and magnetic characterization.

Reduced Graphene Oxide (RGO) has been successfully synthesized by calcination process at 4000C for 4 hours followed by activation with NaOH 1 M. Carbonization is the last process with variations in heating at 6500C, 7500C, 8500C, and 9500C for 1 hour (heating rate 100C / minute). DSC-TGA data shows that there is advanced decomposition at high temperatures, this is confirmed by SEM data which shows the amount of porosity which is getting higher with a size that decreases with temperature. XRD data shows phase differences at low temperatures with a trend of higher levels of crystallinity at high temperatures. Raman spectroscopy data showed an ID / IG ratio of 2.607 and 1.007 on Borassus Flabelifer L with carbonization at 6500C and 9500C respectively. The ID / IG value which is getting closer to 1 indicates that the carbon available in Borassus Flabelifer L has undergone phase changes such as Graphene with a little Oxide commonly called RGO
