German MONTES-HERNANDEZ — 2024-03-10T14:33:52Z

From 2006 to present, several methods to produce mineral and mineral composites under mild and hydrothermal conditions, including the synthesis of nonoparticles, mesocrystals and nanostructured materials were developped at ISTerre (in-house methods). At the present time, the synthesis of more of 40 mineral and crystal phases are handled. In addition to fundamental research on their nucléation processes monitored in real-time, with relevance on the natural and engineered systems. Several of these crystalline phases could offer interesting applications as adsorbents, catalysts (photo-), mineral additives, excipients, permanent storage of carbon dioxide, etc.. In this way, my expertise (supported by about 30% of my research (30 scientific publications and 5 patents)) is open for R&D collaborations with academic and industrial sectors.

German MONTES HERNANDEZ has received a PhD in Earth Sciences from the University of Strasbourg in October 2002. He was a post-doctoral fellowship from 2003 to 2009 at the universities of Strasbourg, Nancy and Grenoble in Earth Sciences departments for each university in France. From October 2009, he was hired as researcher (CR1) in the French National Center for Scientific Research (CNRS). Additionally, in the same year, he has received a HDR habilitation (July 2009) from University of Grenoble to conduct research work in France, i.e. official recognition to supervise Ph.D students.
