Antonio Machado Netto is a Research Associate at the Department of Chemistry at the Universidade Federal de Viçosa (UFV) in Viçosa, Brazil. He holds a degree in Chemical Engineering from UFV. His research is divided into two main areas: waste management and treatment of effluents, including the control of emerging contaminants, and the production of renewable energy, particularly hydrogen evolution. Over the years, Antonio has developed several projects focused on the use of carbon-rich industrial waste to produce biochars, which have been applied in the removal of contaminants from both synthetic and real effluents. More recently, he has been working on the use of biochars derived from agricultural biomass as supports for metallic nanoparticles, which act as catalysts in hydrogen production from storage materials. His work is primarily centered on developing innovative and environmentally sustainable solutions for waste management and renewable energy generation.

Dr. Vilaseca is organic chemist from the University of Barcelona and PhD on paper engineering and recycling from the University of Girona. She is professor at the Chemical Engineering Department of the University of Girona since 2008, and leader of the research group on Advanced Biomaterials and Nanotechnology. Her research expertise comes from about 20 years working mainly on cellulose fibers and on cellulose-based composite materials. As a result, she has published more than 120 JCR articles with 4000 non- self-citations, participated in about 190 Conferences. As for industrial experience, she has been n at the at R&D of two companies, one pulp and paper company and one polymer company. Her current scientific strategy for the coming future encloses 3 main domains: a) Flexible electronics, b) multiscale materials and interface design and c) sustainable design, waste treatment and recycling. In alignment with the new 2030 EU targets in the energy & green deal and in the climate & energy framework, the use of natural resources as well as the waste recovery as key factors in pursuing her research aims. All in all, materials engineering with performance enhancement, tailoring, combined use of materials, electronic properties, interfaces, and nanostructures are key words of my forthcoming research purposes.
