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 ...

Carrasco, Sebastián; Varas, Alejandro; Rogan Castillo, José; Kiwi Tichauer, Miguel; Valdivia Hepp, Juan (Amer Physical Soc, 2016)The particle-particle interaction potential of an N-atom cluster is expanded in n-body contributions. The expansion allows us to determine the magnitude of each one of the n-body terms, and consequently quantifies how ...

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, ...

Muñoz Sáez, Francisco; Romero, A.H.; Mejía López, J.; Roshchin, Igor V.; González, R. I.; Kiwi Tichauer, Miguel (Elsevier, 2015)The (110) surface of iron fluoride (FeF2) is especially relevant to the understanding of the exchange bias phenomenon, which has important applications in the sensor industry, and has been extensively explored, both ...

Reyes, Paula; Valencia, Felipe; Vega, Hector; Ruestes, Carlos; Rogan Castillo, José; Valdivia Hepp, Juan; Kiwi Tichauer, Miguel (Royal SOC. chemistry, 2018-05)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 ...

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 ...

Valencia, Felipe; Ramírez, Max; Varas, Alejandro; Rogan, José; Kiwi Tichauer, Miguel (American Chemical Society, 2020)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 ...

Torres, Felipe; Rogan Castillo, José; Kiwi Tichauer, Miguel; Valdivia Hepp, Juan (AMER Inst. Physics, 2016)A new type of collective excitations, due to the topology of a complex random network that can be characterized by a fractal dimension D-F, is investigated. We show analytically that these excitations generate phase ...

Shiryaev, A. A.; Hinks, J.; Marks, N.; Greaves, G.; Donnelly, S.; Fisenko, A. V.; Kiwi Tichauer, Miguel (Wiley-Blackwell, 2016)Xenon in nanodiamonds from meteorites is a remarkable impurity. At least two isotopically dif-ferent components of Xe are known: P3 and Xe-HL. The P3 component might represent adsorbed Xe; whereas the component enriched ...
