Influence of porosity on high-velocity mass-asymmetric collisions

Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Belen Planes, Maria; Millan, Emmanuel N.; Urbassek, Herbert M. (OXFORD UNIV PRESS, 2020)

Using granular mechanics, we study the influence of porosity on the collisions of spherical granular aggregates with a mass ratio of around 60. At high filling factors, the projectile produces a crater on the target, similar ...
Mechanical Properties Obtained by Indentation of Hollow Pd Nanoparticles

González, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Santiago, Chile]; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Valencia, Felipe J.; Rogan, José; Valdivia, Juan Alejandro; Sofo, Jorge; Kiwi, Miguel; Muñoz, Francisco (AMER CHEMICAL SOC, 2018)

Palladium nanoparticles are technologically important for catalysis, hydrogen storage, and many other applications. Here, we investigate the mechanical properties of Pd hollow nanoparticles of different sizes and thicknesses ...
