Atomistic study of CoCrCuFeNi high entropy alloy nanoparticles: role of chemical complexity
Vermale, Alice; Khelladi, Lilian; Rojas-Nunez, Javier; Baltazar, Samuel; Rogan, José; Ramirez, Max; Roco, Fiorella; Valencia, F. (2024)High entropy alloy nanoparticles are envisaged as one of the most interesting materials compared to monoatomic materials due to their modulated properties in terms of their convenient surface-to-volume ratio. However, ...

Effect of functionalized silica nanoparticles on the mass transfer process in active PLA nanocomposite films obtained by supercritical impregnation for sustainable food packaging
Sepulveda, Javiera; Villegas, Carolina; Torres, Alejandra; Vargas, Esteban; Rodriguez, Francisco; Baltazar, Samuel; Prada, Alejandro; Rojas, Adrian; Romero, Julio; Faba, Simon; Galotto, María J. (2020)Nanocomposite films based on PLA with 1.0 % w/w silica nanoparticles (NP) and surface-functionalized silica nanoparticles with lactic acid (NP-LA), respectively, were obtained by extrusion process. Subsequently, cinnamaldehyde ...

Probing radiation resistance in simulated metallic core–shell nanoparticles
Tramontina, Diego Ramiro; Deluigi, O. R.; Pinzón, R.; Rojas-Nunez, Javier; Valencia, F.J.; Pasianot, R.C.; Baltazar, S.E.; Gonzalez, R. I.; Bringa, E. M. (2023)We present molecular dynamics (MD) simulations of radiation damage in Fe nanoparticles (NP) and bimetallic FeCu core–shell nanoparticles (CSNP). The CSNP includes a perfect body-centered cubic (bcc) Fe core coated with a ...
