Dr. Javier Hernández-Borges is Full Professor of Analytical Chemistry (2022) at the Department of Chemistry at the University of La Laguna (ULL) in Tenerife (Canary Islands, Spain). He obtained his Bachelor in Chemistry at ULL in 2001 as well as his PhD with European mention at that university in 2005, after which, he carried out a postdoctoral stay at the Institute of Chemical Methodologies of the National Research Council of Italy (2006-2007), obtained a Juan de la Cierva contract at the Canarian Institute of Agrarian Research (2007-2008) and a Ramón y Cajal contract at ULL (2009-2013). Afterwards, he was promoted to Associate professor (2014) and Associate Professor with tenure (2017). He has published around 155 papers in international indexed journals and 34 book chapters, most of them dealing with analytical method development, in particular, with the determination of microplastics, pesticides, antibiotics, phthalates and estrogenic compounds residues in environmental and food matrices using mainly chromatographic and electromigration techniques also coupled to mass spectrometry detection. He has directed 10 PhD Thesis, 8 of them awarded with ULL’s PhD Extraordinary Award. Since 2018, he is coordinator of the Applied Analytical Chemistry Research Group (AChem) at ULL, which incorporated from the very beginning a pioneer research line at the university devoted to microplastics research, trying to follow a multidisciplinary approach. In particular, his group has been studying the presence of microplastics in air, soils, food, coastal and deep-sea sediments and also in the water column, monitoring environmental contaminants in microplastics, and determining the microplastic content in different living organisms as well as improving analytical methodologies for microplastics determination and analysis.

Prof. Mohamed Taieb Ben Dhia is Professor and expert in Nuclear Magnetic Resonance (NMR) at the Faculty of Sciences and Technology (FST). He has more than 35 years of continuous experience in teaching, research and advanced NMR applications, and has supervised and co-supervised 15 doctoral theses. His research activities focus on the synthesis of new metal cation complexes with organophosphorus ligands and their structural characterization using NMR spectroscopy. He has conducted in-depth studies on the thermodynamic aspects of dynamic equilibria in solution, particularly cis–trans isomerism, using variable-temperature NMR to determine thermodynamic parameters (ΔH, ΔS, ΔG). His work is complemented by theoretical investigations based on Density Functional Theory (DFT). The developed complexes find applications in catalysis as well as in antibacterial, antioxidant and antifungal activities.
