Estudio de bioactividad en aleaciones Co-Cr con superficies foliculares por Almada Almanza, Vicente Antonio

“…Con el afán de promover una mejor fijación a largo plazo de las prótesis e implantes en general, se han empleado diferentes diseños y/o arreglos de superficies porosas elaboradas en biomateriales como metales, cerámicos, polímeros y compositos. Las técnicas para lograrlo son muy diversas, pasando de las más sencillas (sinterización), hasta las más avanzadas como el uso del rayo laser. …”

Impacto ambiental originado por los lixiviados del relleno sanitario municipal de Linares N.L. México por Cruz Vega, Carlos Ramón

“…The results revealed an existence of a hydro-geochemical evolutional pattern from a composition of bicarbonate-calcium to a bicarbonate-sulfate-calcium, although two of the wells (P1 and P2), placed down stream of the sanitary landfill showed a composition that left this pattern. …”

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

“…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. …”

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

“…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. …”
