    FePt icosahedra with magnetic cores and catalytic shells by Wang, Rongming, Dmitrieva, Olga, Farle, Michael, Dumpich, Güntner, Acet, Mehmet, Mejía Rosales, Sergio, Pérez Tijerina, Eduardo, Yacamán, Miguel José, Kisielowski, Christian

    Published 2009
    “…Computational studies and energy-filtered transmission electron microscopy analyses suggest that a Pt-enriched surface layer is energetically favored and that site-specific vacancies are formed at the edges of facettes, which was experimentally observed. The presence of the Pt-enriched shell around an Fe/Pt core explains the environmental stability of the magnetic icosahedra and strongly reduces the exchange coupling between neighboring particles, thereby possibly providing the highest packing density for future magnetic storage media based on FePt nanoparticles.…”

    On the structure and properties of silver nanoparticles by Gracia Pinilla, Miguel Ángel, Pérez Tijerina, Eduardo, Antúnez García, Joel, Fernández Navarro, Carlos Javier, Tlahuice Flores, Alfredo, Mejía Rosales, Sergio, Montejano Carrizales, Juan Martín, Yacamán, Miguel José

    Published 2008
    “…We also found that both the size and shape of the nanoparticles determine the shift of the UV-visible absorption spectrum. Finally, we observed the formation of atomic islands above the faces of the Ag tetrahedral NPs, in agreement with the results obtained from the MD simulations.…”

    Estimación de los niveles ambientales de formaldehido en clínicas de odontopediatría. by Villarreal González, Adela Andrea

    “…Conclusions The results showed there were formaldehyde concentrations in the air of the clinics, enough to generate irritations in eyes and skin, higher concentrations were also observed in the clinics where the ventilation was zero and they performed a poor management of it.…”
