Researchers from Khalifa University in Abu Dhabi, in collaboration with the University of Manchester, have made a significant breakthrough in the field of graphene technology. By fine-tuning the properties of graphene using electric fields, they developed a dual-functional device that can impact hydrogen fuel cells, computing, and catalysis. The research, published in Nature, showcases how a graphene sheet can independently host proton and electron currents, paving the way for innovative applications. The study explores the control of proton transport and hydrogenation in graphene, enabling the device to potentially combine memory and logic functions in a single unit, eliminating the need for additional circuits. This breakthrough not only advances graphene-based technologies but also has implications for hydrogen-related applications, catalysis, and isotope separation. The collaboration between Khalifa University and international institutions highlights the strength of cross-disciplinary research and sets the stage for future innovations in materials science and energy technologies.
