    • Dispersion of carbon nanotubes in aluminum improves radiation resistance 
      So, Kang Pyo; Chen, Di; Kushima, Akihiro; Li, Mingda; Kim, Sangtae; Yang, Yang; Wang, Zigiang; Park, Jong Gil; Lee, Young Hee; González, Rafael I.; Kiwi Tichauer, Miguel; Bringa, Eduardo M.; Shao, Lin; Li, Ju (Elsevier, 2016)
      We can mass-produce metal/carbon nanotube (CNT) composites that show improved radiation tolerance. The 0.5 wt% Al+CNT composite showed improved tensile strength without reduction of tensile ductility before radiation, and ...
    • Hillock formation on nanocrystalline diamond 
      Díaz Valencia, Felipe; González, Rafael I.; Bringa, Eduardo M.; Kiwi Tichauer, Miguel (Elsevier, 2017-08)
      Hillock formation on nanocrystalline (nc) diamond under swift heavy ion irradiation is studied by means of classical molecular dynamics. The irradiation is simulated by means of a thermal spike model, the nc samples include ...
    • Hydrogen Storage in Palladium Hollow Nanoparticles 
      Valencia, Felipe; González, Rafael I.; Tramontina, Diego; Rogan Castillo, José; Valdivia Hepp, Juan; Kiwi Tichauer, Miguel; Bringa, Eduardo (American Chemical Society, 2016-10-20)
      The potential and properties of palladium hollow nano particles (hNPs) as a possible H storage material are explored by means of classical molecular dynamics (MD) simulations. First, we study the stability of pure Pd hNPs ...
    • Imogolite in water: simulating the effects of nanotube curvature on structure and dynamics 
      González, Rafael I.; Rojas Núñez, Javier; Valencia, Felipe; Muñoz Sáez, Francisco; Baltazar, Samuel; Allende, Sebastián; Rogan Castillo, José; Valdivia Hepp, Juan; Kiwi Tichauer, Miguel; Ramírez, Ricardo; Greathouse, Jeffery A. (Elsevier, 2020)
      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. ...
    • Inducing porosity on hollow nanoparticles by hypervelocity impacts 
      Valencia, Felipe J.; González, Rafael I.; Valdivia Hepp, Juan; Kiwi Tichauer, Miguel; Bringa, Eduardo M.; Rogan Castillo, José (American Chemical Society, 2017)
      The large surface-to-volume ratio of hollow palladium nanoparticles (hNPs) offers room to improve their hydrogen storage capacity as well as their catalytic activity. However, a less explored possibility is to use, in ...
    • Mechanical Properties Obtained by Indentation of Hollow Pd Nanoparticles 
      Valencia, Felipe; González, Rafael; Vega, H.; Ruestes, Carlos; Rogan Castillo, José; Valdivia, Juan; Bringa, Eduardo; Kiwi Tichauer, Miguel (American Chemical Society, 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 ...
    • Metal-nanotube composites as radiation resistant materials 
      González, Rafael I.; Valencia, Felipe; Mella, José; van Duin, Adri C. T.; So, Kang Pyo; Li, Ju; Kiwi Tichauer, Miguel; Bringa, Eduardo M. (Amer Inst Physics, 2016)
      The improvement of radiation resistance in nanocomposite materials is investigated by means of classical reactive molecular dynamics simulations. In particular, we study the influence of carbon nanotubes (CNTs) in an Ni ...
    • Thermal stability of aluminum oxide nanoparticles: Role of oxygen concentration 
      Ramírez, Max; González, Rafael I.; Baltazar, Samuel E.; Rojas-Nunez, Javier; Allende, Sebastián; Valdivia, Juan Alejandro; Rogan Castillo, José; Kiwi Tichauer, Miguel; Valencia, Felipe (Royal Society of Chemistry, 2019)
      Oxygen absorption and the thermal stability of Al147 nanoparticles were studied by means of classical molecular dynamics simulations and Monte Carlo methods. The results suggest that for the studied sizes, oxygen incorporation ...
