Participation of GQM in the reportage of Fantástico

This past Sunday, our group (GQM-UFPR) participated in a beautiful and much needed report on Fantástico (@showdavida) about Brazilian science. Here it was demonstrated that science has always gone through difficulties and how in the last four years this situation has worsened with the absurd cuts it has suffered. Today, with countless broken equipment, researchers without salaries and brain drain, universities in Brazil continue to face and fight to do the cutting-edge science they have always done.

You can see the complete report in the button "Read more".


This week we are receiving two French researchers, the result of a collaboration in a CAPES/COFECUB project that is coordinated by Prof. Aldo Zarbin. Prof. Eric from the University of Montpellier, who specializes in vibrational spectroscopy, and Prof. Alain Penicaud from the University of Bordeaux, who specializes in the preparation of colloidal dispersions of nanostructures, mainly carbon. In addition to the visit, the professors honored us with incredible lectures. Prof. Eric brought a little about his work with “Near infrared spectroscopic studies of single-walled carbon nanotubes” and Prof Alain enchanted us with “The Story of NanoCarbons”.
