Research infrastructures

An international study, involving the Italian National Research Council (CNR – Istituto Officina dei Materiali) and the Universities of Trieste and Milano-Bicocca for Italy, along with the University of Vienna, has unveiled a simple and innovative method for creating a new category of materials. These materials combine the exceptional properties manifested by individual metal atoms with the robustness, flexibility and versatility of graphene, for potential applications in the fields of catalysis, spintronics and electronic devices. The study is published in Science Advances: the method involves depositing metal atoms, such as cobalt, in a controlled manner, during the formation of the graphene layer on a nickel surface. Some of these atoms are incorporated into the carbon network of graphene, forming a new material with exceptional robustness, reactivity and stability. The method was developed at the CNR-IOM laboratories in Trieste: “This is still a preliminary result, but it is already very promising and the result of an original idea that arose in our laboratory and initially seemed unfeasible,” says Cristina Africh, a researcher at the CNR-IOM who led the team. The material’s ability to detach from the substrate while maintaining its original structure makes it potentially usable in various applications. “The methodology has been tested for trapping nickel and cobalt atoms, but our calculations suggest that it could be extended to other metals for different applications,” explains Cristiana Di Valentin, professor of General and Inorganic Chemistry at the University of Milano-Bicocca. Moreover, the material has proven to be stable even under critical conditions. “We have demonstrated that this material remains intact even in critical conditions, including the electrochemical environments used for applications in fuel cells and batteries,” adds Jani Kotakoski of the University of Vienna. The study, which is the result of international collaboration, made use of different and complementary skills. “This aspect was decisive in demonstrating the effectiveness of this approach, which is simple and powerful at the same time,” concludes Giovanni Comelli from the University of Trieste.

An international forum dedicated to the value and role of large research infrastructures in scientific progress and their economic, social and geopolitical impacts on a global scale. These were the central themes of the G7 conference “Large Research Infrastructures: Synergies and Impact on Science and Society”, organized by the Ministry of University and Research in collaboration with the National Institute for Nuclear Physics (INFN) under the Italian G7 Presidency, and held in Sardinia from October 28th to 30th in Su Gologone (Nuoro). The rich three-day program featured four thematic sessions, dedicated to exploring the key role of large research infrastructures in generating knowledge and value for society, promoting the sharing of ideas and best practices among policymakers, researchers, and socio-economic stakeholders. The opening remarks were delivered by the Minister of University and Research, Anna Maria Bernini, and the President of the Autonomous Region of Sardinia, Alessandra Todde. Among the nationally and internationally prominent speakers was also the President of Area Science Park, Caterina Petrillo, who contributed to the roundtable The Socio-Economic Benefits of Large Research Infrastructures. Here, speakers discussed the role of large infrastructures: not only centers for scientific knowledge production and high-quality FAIR data, but also true catalysts of innovative processes, which include training new generations of scientists, transferring technology to industry, and fostering regional development. During her speech, the President highlighted the importance of integrating these infrastructures into innovative ecosystems, scientific, and technological hubs, both public and private, where collaboration and shared projects can thrive. The objective of the G7 Conference on Large Research Infrastructures: Synergies and Impact on Science and Society is to stimulate dialogue to facilitate collaboration among the G7 countries, in order to optimize resources and maximize the complementarity of these large infrastructures, aiming toward a future of shared and sustainable innovation.
