    Gold−Copper Nano-Alloy, “Tumbaga”, in the era of nano: phase diagram and segregation por Guisbiers, Grégory, Mejía Rosales, Sergio, Khanal, Subarna, Ruiz Zepeda, Francisco, Whetten, Robert L., Yacamán, Miguel José

    Publicado 2014
    “…One finds, for all the shapes investigated, that the congruent melting point of these nanoparticles is shifted with respect to both size and composition (copper enrichment). Segregation reveals a gold enrichment at the surface, leading to a kind of core–shell structure, reminiscent of the historical artifacts. …”

    Experimental evidence of icosahedral and decahedral packing in one-dimensional nanostructures por Velázquez Salazar, J. Jesús, Esparza, Rodrigo, Mejía Rosales, Sergio, Estrada Salas, Rubén, Ponce, Arturo, Deepak, Francis Leonard, Castro Guerrero, Carlos Fernando, Yacamán, Miguel José

    Publicado 2011
    “…These nanowires, formed by the reaction of a mixture of metal salts (Au and Ag) in the presence of oleylamine, are obtained when the chemical composition is specifically Ag/Au = 3:1. The experimental images of the icosahedral nanowires have a high likelihood with simulated electron micrographs of structures formed by two or three Boerdijk Coxeter Bernal helices roped on a single structure, whereas for the decahedral wires, simulations using a model of adjacent decahedra match the experimental structures. …”

    Polycrystalline thin films of antimony selenide via chemical bath deposition and post deposition treatments por Rodríguez Lazcano, Yamilet, Peña Méndez, Yolanda, Nair Maileppallil, Santhamma, Nair Padmanabhan, Karunakaran

    Publicado 2005
    “…The thin films deposited from chemical baths containing one or more soluble complexes of antimony, and selenosulfate initially did not show X-ray diffraction (XRD) patterns corresponding to crystalline antimony selenide. Composition of the films, studied by energy dispersive X-ray analyses indicated selenium deficiency. …”

    FeS₂/ZnO core/shell nanowires: structural, optical and electrochemical properties. por Retana Betancourt, María Fernanda

    Publicado 2016
    “…Altough, many efforts have been done in order to find the characteristics and properties that allow the subsequent production and commercialization, hybrid solar cells represent an interesting option for this purpose. The composition in the photoactive layer is key in order to obtain high values of efficiencies and where the use of nanosized materials with one-dimensional morphology embedded into polymeric matrix allows the improvement of their optoelectronic properties. …”

    Insights into the Potential of Pre-Processing of Ingredients to Improve their Economical Value to Aquaculture Species por P Bureau, Dominique, Yang, Yuhong, Cai, Chunfang, Pfeuti, Guillaume

    Publicado 2017
    “…However, the variability of the chemical composition of different batches of these ingredients and the relatively low digestibility of some of the nutrients (i.e. amino acids, phosphorus) occasionally represent significant limitations for these ingredients at high levels in the diet of some species. …”
