Nanotechnology allows us to build powerful and smaller electronics, helps develop energy sources, solar panels, and catalysts. Graphene is composed of one layer of honeycomb-like Carbon atoms. It has electronic properties and can transport charges without resistance. We focused on theoretical/computational analysis of metal clusters on nanographene. Calculations were performed to study the physical/chemical properties of metal on nanographene using the supercomputer in University Park. This analysis focuses on energy, optical/magnetic properties, and chemical properties.
