Income divergence between mexican states in the 1990s: the role of skill premium por Aguayo Téllez, Ernesto

“…Using microdata from the 1990 and 2000 Mexican Population Censuses, this study decomposes the recent divergence into components due to economy-wide changes in skill prices and components due to state-specific changes in the composition of workers. The study finds that the rise in the education premium hindered the progress of poor states and raised the variance of average state wages and labor earnings. …”

Highly size-controlled synthesis of Au/Pd nanoparticles by inert-gas condensation por Pérez Tijerina, Eduardo, Gracia Pinilla, Miguel Ángel, Mejía Rosales, Sergio, Ortiz Méndez, Ubaldo, Torres, A., Yacamán, Miguel José

“…The structure and size of the Au/Pd nanoparticles were determined by mass spectroscopy, and confirmed by atomic force microscopy and electron transmission microscopy measurements. The chemical composition was analyzed by X-ray microanalysis. From these measurements we confirmed that with the sputtering technique we are able to produce particles of 1, 3, and 5 nm on size, depending on the choice of the synthesis conditions. …”

Desarrollo de películas biodegradables basadas en un sistema ternario almidón de yuca–alcohol polivinílico–bentonita sódica para aplicaciones en la conservación de frutas tropicale... por Pérez Pacheco, Emilio, Ortiz Fernández, Alejandro

“…Los resultados mostraron que las películas ternarias presentaron espesores mayores (125–128 µm) en comparación con las monocomponentes (96–110 µm), lo que refleja una red polimérica más densa y estable. En cuanto a opacidad, las formulaciones con mayor proporción de PVA (F4 y F5) fueron las más transparentes (L* = 74.82–75.55), lo que refleja la capacidad de este polímero para formar películas claras y homogéneas. …”

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. …”

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

“…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

“…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. …”
