Ni clusters embedded in multivacancy graphene substrates
Autor: Jorge Mario Marchetti, R.E. Ambrusi, V. Orazi, M.E. Pronsato
In the present study, we performed density functional theory (DFT) calculations in order to study the structure and stability of small Ni clusters embedded in graphene multivacancy systems. The Bader charges, band structure, total density of states,

Underpotential deposition and involved alloy formation of cadmium on silver particles modified HOPG substrates
Autor: S.G. García, M.E. Pronsato, Rubén Eduardo Ambrusi
Cadmium underpotential deposition (UPD) on Ag particles modified highly ordered pyrolytic graphite (HOPG) surfaces, and the involved alloy formation were studied by conventional electrochemical techniques. Voltammetric results indicated that the Cd U
