Prof. Dr. Fernando Galembeck: Born in São Paulo, Brazil in 1943. Chemistry B.Sc. (1964) and Ph.D. (1970, University of São Paulo - USP), research fellow in the Universities of California and Colorado (1972-4) and in the Unilever Res. Port Sunlight Lab. (1976). Career: USP lecturer to associate professor (1964-1980) and Unicamp (1980-2011), full professor since 1987. Director of the Brazilian National Nanotechnology Laboratory (2011-5), currently Guest Professor at Unicamp. Advised 35 Ph.D. students, published 241 papers, 6 review articles, 50 editorials, edited or authored three books and contributed chapters to six others. Inventor listed in 28 patents that led to 4 products launched in the market. Consultant of product and process development and scientific board member in many funding agencies and companies. Member of the Brazilian Academy of Sciences, TWAS, and Tellesio-Galilei Academy, received many prizes for scientific achievement and innovation, in Brazil, France and US.  Prof. Dr. Thiago A. L. Burgo: received his BSc degree (Chemistry) from the State University of Maringa and his PhD from the University of Campinas (2013), working on the triboelectrification of dielectric polymers, when he identified charge carriers and showed for the first time their effects on friction coefficients. Afterwards, he joined the Argonne National Laboratory (Chicago, USA) as a postdoc, investigating the exchange of electric charge at metal–insulator interfaces during friction force fluctuations. His research interests include scanning probe microscopy, electrostatic adhesion, stream electricity and functional materials. Received two consecutive prizes from Electrostatics Society of America for his works dealing with electrostatics of polymers and friction phenomena related to electric charges.
