Dr. Ramiro Pérez Campos obtained his Ph. D. in Physics at the University of Alberta, Canada in 1983. He also carried out postdoctoral work at the KFA in Jülich, Germany. He was awarded an Alexander Von Humboldt postdoctoral scholarship. He is the author of more than 170 scientific papers, all of them related with the applications of the transmission electron microscope in materials science. He is the actual Director of Centro de Física Aplicada y Tecnología Avanzada of the Universidad Nacional Autónoma de México.Dr. Antonio Contreras Cuevas is a pipeline materials research specialist for Mexican Petroleum Institute since 2003. He obtained a master degree in 1997 and PhD in 2002 in Metallurgy and Materials Science from Universidad Nacional Autónoma de México (UNAM). He is a member of NACE and Mexican Materials Society, and he belongs to National Research System. The main research areas include stress corrosion cracking (SCC), root cause analysis (RCA), materials characterization and pipeline integrity. He is author from more than 50 scientific papers related with materials characterization by different techniques. Actually, he is researcher of Mexican Petroleum Institute.Dr. Rodrigo A. Esparza Muñoz obtained his Ph.D. in Metallurgy and Materials Science at the Universidad Michoacana de San Nicolás de Hidalgo (UMSNH), México in 2007. He carried out two postdoctoral stays, one of them in the Universidad Nacional Autónoma de Mexico (UNAM) and the other one, in the University of Texas at San Antonio (UTSA). He is the author of more than 50 scientific papers, most of them related with the characterization of nanomaterials using high-resolution transmission electron microscopy and aberration-corrected scanning transmission electron microscopy. Actually, he is researcher of Centro de Física Aplicada y Tecnología Avanzada from Universidad Nacional Autónoma de México.
