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. …”

Reliability of X7R Multilayer Ceramic Capacitors During High Accelerated Life Testing (HALT) por Hernández López, Ana María, Aguilar Garib, Juan Antonio, Guillemet Fritsch, Sophie, Nava Quintero, Román Jabir, Dufour, Pascal, Tenailleau, Christophe, Durand, Bernard, Valdez Nava, Zarel

“…It is known that the reliability of MLCCs depends on their composition, processing, and operating conditions. In this present work, we analyzed the lifetime of three similar X7R type MLCCs based on BaTiO3 by conducting High Accelerated Life Tests (HALT) at temperatures up to 200 ◦C at 400 V and 600 V. …”

Bovine Dialyzable Leukocyte Extract IMMUNEPOTENT CRP: Evaluation of Biological Activity of the Modified Product por Franco Molina, Moisés Armides, Santana Krimskaya, Silvia Elena, Zárate Triviño, Diana Ginette, Zapata Benavides, Pablo, Hernández Martínez, Sara Paola, Cervantes Wong, Fernanda, Rodríguez Padilla, Cristina

“…In this study, we evaluated and compared the chemical composition (bromatological analysis), physical structure (infrared spectroscopy, X-ray diffraction, SEM, and zeta potential) and biological function of the dialyzable leukocyte extracts obtained from fresh and dry bovine spleens. …”

Testing evolutionary models to explain the process of nucleotide substitution in gut bacterial 16S rRNA gene sequences por Garcia Mazcorro, José F.

“…The 16S rRNA gene has been widely used as a marker of gut bacterial diversity and phylogeny, yet we do not know the model of evolution that best explains the differences in its nucleotide composition within and among taxa. Over 46 000 good-quality near-full-length 16S rRNA gene sequences from five bacterial phyla were obtained from the ribosomal database project (RDP) by study and, when possible, by within-study characteristics (e.g. anatomical region). …”

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. …”

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

“…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. …”
