Jesús Velázquez

Research in the Velázquez group is centered on the rational design of well-defined dimensionally reduced materials, ranging from monolayers, bilayers, nanocrystalline thin films, and free-standing mesoporous monoliths. The target materials have immediate applications in nanoelectronics, energy conversion devices and environmental remediation. Characterization of the physicochemical properties of these materials involves a combination of microscopy, spectroscopy, electrochemistry and synchrotron-based methods and will facilitate the development of structure-function correlations that will iteratively inform materials design.
