1. Análise macroscópica do efeito da adição de nanocerâmica ao concreto
Nanoscience and nanotechnology are areas that have a great potential for new materials and new applications development. Recently many researches are using the nanotechnology concept to create Portland concrete composites, where they look for the comprehension of the hydration of cement particles and addition of nanometrics (nm) particles, either nano-silica

2. Redução aluminotérmica do óxido de tântalo usando uma tocha de plasma como ignitor
In this work was used a plasma torch of non transferred arc with argon as work gas, using a power supply with maximum DC current of 250 A and voltage of 30 V to activate the plasma and keep it switched on. The flame temperature was characterized by optical emission spectroscopy, through Boltzmann-plot-method. The torch has been used like igniter in the alumi
