On the structure and properties of silver nanoparticles por Gracia Pinilla, Miguel Ángel, Pérez Tijerina, Eduardo, Antúnez García, Joel, Fernández Navarro, Carlos Javier, Tlahuice Flores, Alfredo, Mejía Rosales, Sergio, Montejano Carrizales, Juan Martín, Yacamán, Miguel José

“…We performed a set of Molecular Dynamics (MD) calculations using the Embedded Atom potential model to simulate the dynamics of particles with different shapes, obtaining that, at sizes close to that of the particles produced experimentally, the tetrahedra may be as energetically stable as cuboctahedra of roughly the same size, and that their melting point is below but close to that of the bulk. We also found that both the size and shape of the nanoparticles determine the shift of the UV-visible absorption spectrum. …”
