Leaching of Ni and Cu from mine wastes (tailings and slags) using acid solutions and A. ferrooxidans
The objective of this work is to evaluate the acidic and biological leaching of tailings containing Ni/Cu from a flotation and smelting plant. Acidithiobacillus ferrooxidans, strain LR, was used for bioleaching at pH 1.8 ...
Glass-ceramic material from the SiO 2-Al 2O 3-CaO system using sugar-cane bagasse ash (SCBA)
Brazil is the world's largest producer of alcohol and sugar from sugarcane. Currently, sugarcane bagasse is burned in boilers to produce steam and electrical energy, producing a huge volume of ash. The major component of ...
New materials for energy and biomedical applications
We have conducted research works on the synthesis and characterization of ceramic materials for energy technologies and the characterization of bioceramics and composites for dental applications. La0.50Li 0.50TiO3 nanoparticles ...
Efficiency analysis of an isolated high voltage gain converter operating in resonant and non-resonant mode
This paper presents an efficiency investigation of an isolated high step-up ratio dc-dc converter aimed to be used for energy processing from low-voltage high-current energy sources, like batteries, photovoltaic modules ...
