Araceli Granja


Araceli Granja Alvear, Ecuadorian, graduated in Chemistry in the first cohort of the Yachay Tech University, currently a Master’s student in Chemical Sciences with a Major in Materials Science and Engineering at the Yachay Tech University.

Research Projects

Araceli has actively participated in various research projects, with two research stays at the Benemérita Universidad Autónoma de Puebla, (BUAP) Puebla-Mexico (2018-2019), and another at the Center for Nanosciences and Nanotechnology of the National University of Mexico (UNAM) in Ensenada-Mexico(2019). She has worked on the synthesis and characterization of thin polymer films such as alcohol. polyvinyl and pectin loaded with silver nanoparticles of various shapes and sizes, exploring their adjustable plasmonic and electrical properties. Her contributions include publishing scientific articles in SciELO Materials Research and presenting her findings at international conferences. Additionally, she has investigated the antimicrobial activity of silver nanoparticles and the extraction of chitosan from natural resources such as crab shells. His dedication to academic excellence and innovation has earned him recognition for his work, such as second place in the Senescyt-Ecuador Cannabis and Technology innovation challenge, as well as recognition for his contribution to research at the IST 17 de Julio Ecuador.
