Abstract

Prof. Gabriel Meyer has outstanding experience in the development of instrumentation for the determination of hydrogen storage properties in materials, as well as in research on synthesis, processing, structure and properties of complex and metal hydrides. Thus, it is expected that the visiting researcher will contribute in a remarkable way to our group, considering our initiatives for the construction of equipment to measure kinetic and thermodynamic properties of the reactions of solids with H2. In addition, the experiments of the Brazilian and Argentinean group will be articulated in a research project on Mg-AB5 nanocomposites for hydrogen storage. We have worked in Mg-based systems, that shows high storage capacity (7.6% by mass) and high operating temperatures (~ 300 ° C); Prof. Meyer's research team is specialized in AB5 intermetallic systems, such as LaNi5, which has low hydrogen capacity (1.5% by mass), but is able to operate at room temperature. The idea is to investigate ways to produce Mg - AB5 nanocomposites that combine the advantages of both types of materials. The visiting researcher will also assist us in the technical evaluation of several ongoing studies, and will disseminate his knowledge as an invited speaker in the NANOMAT 2017 conference, to be held between March 19 and 22, 2017 in Brotas, SP, and also with short visits to FCA / UNICAMP and IPEN.
