Mohamed Achache is currently a Ph.D. candidate in the Department of Chemistry at the Faculty of Sciences of Tétouan, Abdelmalek Essaâdi University (Morocco). He earned his Bachelor's degree in Chemistry in 2019 with distinction ("Bien"), graduating at the top of his class. In 2021, he completed his Master's degree in Chemistry, once again with distinction and ranking first in his cohort. In recognition of his academic excellence, he was awarded a Research Excellence Scholarship by the CNRST in 2022. As part of the Erasmus+ KA107/171 mobility program, he carried out a six-month research internship (February–July 2023) with the FQM-249 research group at the Department of Analytical Chemistry, University of Cádiz, under the supervision of Professors José María Palacios Santander and Laura Cubillana Aguilera. His current doctoral research is conducted within the Laboratory of Materials Engineering and Sustainable Energy (LIMED), where he focuses on the development of modified electrodes based on carbon paste and sonogel, nanomaterials (including nanoparticles, nanocomposites, and graphene oxide), and the valorization of natural resources such as clay, shrimp waste, and phosphate. His research interests extend to electrochemical sensors, electroanalysis of pharmaceutical, biological, food, and environmental samples, chemometrics, corrosion studies, adsorption processes, and the application of analytical techniques including SEM/EDS, FTIR, XRD, UV-Vis, and zeta potential analysis.
