Rafael Chaves Lima has a bachelor in Chemistry from Universidade Estadual do Ceará and, currently, he is finishing his master's degree in Chemistry from Universidade Federal do Rio Grande do Norte under the direction of Prof. Dr. Sibele Pergher and Dr. Lindiane Bieseki. His research is focused on inorganic physicalchemistry, specifically on zeolite synthesis and the use of alternative sources to obtain microporous materials.

Lindiane Bieseki obtained her Doctoral degree in Materials Science and Engineering from Universidade Federal do Rio Grande do Norte in 2016 under the direction of Prof. Dr. Sibele Pergher and Prof. Dr. Fernando Rey (from the Institute of Chemical Technology - ITQ/CSIC - in Spain). She has experience in Chemistry and in synthesis and preparation of catalysts and environmental chemistry. She acts mainly on the following topics: acid treatment and pillarization of clays, synthesis of zeolites with emphasis on the use of natural raw materials and silicoaluminous residues, and synthesis of mesoporous materials, such as SBA-15.

Paloma Vinaches Melguizo obtained her Doctoral degree in Materials Science and Engineering from Universidade Federal do Rio Grande do Norte (UFRN) in 2017 under the direction of Prof. Dr. Sibele Pergher. She is specialized in zeolite synthesis and characterization with emphasis in direction and the use of alternative raw materials, such as raw powder glass or kaolin.

Sibele Berenice Castellã Pergher obtained Chemical Engineering degree at the Federal University of Rio Grande do Sul (UFRGS) on 1990. Masters in Chemical Engineering, degree obtained at the State University of Maringá (UEM) on 1993. Doctor (PhD) in Chemistry, degree obtained at the Universidad Politecnica de Valencia - Spain on 1997. Two Postdoctoral degrees obtained at the Chemistry Institute of UFRGS (2002 and 2009). She was Professor and researcher at the Federal University of Rio Grande do Sul from 1998 to 2001. She
