Electrophoretic deposition an emerging technology to support fuel cell nanoelectrocatalysts

Oropeza Guzmán M., Gochi-Ponce Y., Moreno G., Tecnologico Nacional de Mexico-Instituto Tecnologico de Tijuana, MX

A new challenge of nanoelectrocatalytic materials is to find a convenient method to support them on surfaces serving as fuel cell electrodes. Traditionally, researchers have tried to prepare colloidal inks containing the nanoelectrocatalyst previously synthesized [...]

Characterization of Polymer Nanocomposites with Thermal Analysis and Spectrum techniques

Mena Navarro M.E., Estrada Guerrero R.F., Torres González L.A., Tinajero R., Palafox L., Universidad Iberoamericana Ciudad de Mexico, MX

Polymer nanocomposites have attracted attention in materials science because they exhibit different properties from those of their counterpart polymer microcomposites. An important characteristic is the size of nanoparticles, their effects increase because of their scattering [...]

Nonclassical Fullerenes with Cubic and Octahedral Structure

Sanchez-Bernabe F.J., Universidad Autónoma Metropolitana, MX

Two types of nonclassical fullerenes are presented: the first one with 128 carbons, with a cubic structure. The second example, with 132 carbons, has octahedral structure. Fullerenes are important on diverse applications. "Brazuka" soccer ball [...]

Three Examples of Nonclassical Fullerenes with Tetrahedral Structure

Sanchez-Bernabe F.J., Universidad Autónoma Metropolitana, MX

Three nonclassical fullerene are presented, they contain square and heptagonal faces, besides pentagons, and hexagons. The number of carbons are 64, 76, and 152, respectively. The first example that we consider of a nonclassical fullerene [...]

Mechanical Properties of a composite material made of HAp nanofibers

Alanis J.R., Velazquez R., Rivera E.M., Universidad Autónoma de Querétaro, MX

Biomaterials based on hydroxyapatite (HAp) are often studied due to the favorable answer presented as a substitute of bone tissue. However, the mechanical properties of these materials have not been studied deep enough. Synthesis of [...]

Polyurethane Nanocomposite for Fireproof Applications to reduce toxic gases

Mena M.E., Estrada R., Torres L.A., Universidad Iberoamericana Ciudad de Mexico, MX

Rigid polyurethane foams have a wide range of applications such as insulation, packaging, among others, due to their excellent properties. However, as most organic materials are moderately flammable and the flame propagation is very fast; [...]

Hydrogen Adsorption on Isoreticular Metal-Organic Framework

Loera-Serna S., López-Sosa S., Universidad Autónoma Metropolitana, MX

Implement the use of hydrogen as an alternative energy source would reduce the use of fossil fuels, therefore it seeks to challenge any difficulty, mainly storage; an alternative of great interest is the use of [...]

Dyes Adsorption on Cu3(BTC)2 Metal-Organic Framework

Loera-Serna S., Garcia-Ortiz J., Garcia-Ortiz J., Universidad Autónoma Metropolitana, MX

The present work suggests an alternative to the solution of environmental problems caused by the textile industry effluents, which contain natural dyes and non-biodegradable synthetic mostly. This solution is the use of porous metal-organic frameworks [...]

Luminiscent properties of europium-1,4-benzenedicarboxylate synthesized at room temperature

Loera-Serna S., Medina-Díaz J.C., Carmona Téllez S., Universidad Autónoma Metropolitana, MX

For many years the lanthanides have been considered as a series of complex, difficult to understand elements, however, research on them has not been adequate. In view of the many properties that have, in the [...]

Structural and Luminescent properties of Europium benzene-1,3,5-tricarboxylate

Alejandre-Zuniga B.Y., Loera-Serna S., Medina-Velazquez D.Y., Universidad Autonoma Metropolitana-Azcapotzalco, MX

The increasing demand of optoelectronic devices requires the development of luminescent materials with high luminescence quantum efficiency and reduced energy consumption, to this organic matrix materials doped with rare earths offer an great alternative. The [...]
