Highly porous tungsten for plasma-facing applications in nuclear fusion power plants: a computational analysis of hollow nanoparticles
Díaz-Rodríguez, Pablo; Muñoz, Francisco; Rogan, José; Martin-Bragado, Ignacio; Perlado, J. M.; Peña-Rodríguez, Ovidio; Rivera, Antonio; Valencia, Felipe J. [Univ Mayor, Fac Ciencias, Ctr Invest DAiTA Lab, Chile] (IOP Publishing Ltd., 2020-09)Plasma-facing materials (PFMs) for nuclear fusion, either in inertial confinement fusion (ICF) or in magnetic confinement fusion (MCF) approaches, must withstand extremely hostile irradiation conditions. Mitigation strategies ... -
Imogolite in water: Simulating the effects of nanotube curvature on structure and dynamics
Gonzalez, Rafael I. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Rojas-Nuñez, Javier; Muñoz, Francisco; Baltazar, Samuel E.; Allende, Sebastián; Rogan, José; Valdivia, Juan Alejandro; Kiwi, Miguel; Ramírez, Ricardo; Greathouse, Jeffery A. (Elsevier BV, 2019-07)Imogolite is a fascinating inorganic nanotube that is found in nature or synthesized in a laboratory. The synthesis process is carried out in liquid media, and leads to the formation of almost monodisperse diameter nanotubes. ... -
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 ... -
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
Pinto, Benjamin [Univ Mayor, Escuela Construcc, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Kiwi, Miguel; Ruestes, Carlos J.; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Rogan, José (Elsevier, 2020-06)Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ... -
The stability of hollow nanoparticles and the simulation temperature ramp
Valencia, Felipe J. [Univ Mayor, Fac Ciencias, Nucleo Matemat Fis & Estadist, Santiago, Chile]; Reyes, Paula N.; Vega, Héctor; Ruestes, Carlos; Rogan, José; Valdivia, J. A.; Kiwi, Miguel (ROYAL SOC CHEMISTRY, 2018)Hollow nanoparticles (hNPs) are of interest because their large cavities and small thickness give rise to a large surface to volume ratio. However, in general they are not in equilibrium and far from their global energy ... -
Thermal Stability of Hollow Porous Gold Nanoparticles: A Molecular Dynamics Study
Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Ramirez, Max; Varas, Alejandro; Rogan, José; Kiwi, Miguel (American Chemical Society, 2020-12)Hollow nanoparticle structures play a major role in nanotechnology and nanoscience since their surface to volume ratio is significantly larger than that of filled ones. While porous hollow nanoparticles offer a significant ... -
Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells
Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Ramírez, Max; Varas, Alejandro; Rogan, José (Chile. Universidad Mayor, 2020)The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
