    • 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 ...
    • 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 ...
    • Ion implantation in nanodiamonds: size effect and energy dependence 
      Shiryaev, Andrey A.; Hinks, Jonathan A.; Marks, Nigel A.; Greaves, Graeme; Valencia, Felipe J.; Donnelly, Stephen E.; Gonzalez, Rafael I.; Kiwi Tichauer, Miguel; Trigub, Alexander L.; Bringa, Eduardo M.; Fogg, Jason L.; Vlasov, Igor I. (Nature Publishing Group, 2018)
      Nanoparticles are ubiquitous in nature and are increasingly important for technology. They are subject to bombardment by ionizing radiation in a diverse range of environments. In particular, nanodiamonds represent a variety ...
    • 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 ...
    • Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role 
      Valencia, Felipe; Pinto, Benjamín; Kiwi Tichauer, Miguel; Ruestes, Carlos J.; Bringa, Eduardo M.; Rogan, José (Elsevier, 2020)
      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, ...
