Miguel A. Gracia-Pinilla is Professor at the Facultad de Ciencias Físico Matemáticas, Universidad Autónoma de Nuevo León, Mexico. Academic leader in the study of Interfaces in micro/nanofabrication. In the last years I have developed micro/nanofabrication processes towards new functional materials to apply to Solar Cells, Battery, Battery Solar Cells and Advanced Oxidation Processes, I am working on the processing of nanomaterials interfaces (Inorganic nanostructures) and other macroscopic substrates (e.g. glass, polymers) by 3D Printing, thin film deposition, and surface modification 2014-2015- Visiting Professor (Sabbatical Year) at Florida International University. 2022-2023 - Guest research (Sabbatical year at University of Twente), working in Additive Manufacturing (3D printing and electrospinning). Claudia Rosa Santiago-Ramírez is a postdoctoral researcher at the Universidad Autónoma de Nuevo León (UANL) and a faculty member at Tecnológico de Monterrey, where she teaches and mentors students in applied research. She obtained a Ph.D. in Nanosciences and Micro-Nanotechnologies from the Instituto Politécnico Nacional (IPN), graduating cum laude. Her research focuses on developing nanostructured materials for energy and environmental applications, with expertise in photoelectrochemical, electrochemical processes, as well as advanced material characterization.
