Development Antifog Nanohybrid Consisting of Polyestyrene Recycled Matrix by Sol-Gel Process

Hernández-Padrón G., Gómez-Quintero T., Blanco-Hernández A., UNAM, MX

A hybrid material consisting of SiO2 nanoparticles embedded in polystyrene recycled matrix has been developed. A polymer of polystyrene recycled functionalized (PSR-F) was used to influence the morphological and antifog properties of sol-gel synthesized silica [...]

Sustainability Stations

Guadalupe Morales M., UNAM, MX

The Sustainability Stations is a project focused in solve Mexico City´s problem of lack of water and inundations. Both situations are related to the water extraction from the water table, being the principal source of [...]

Energy balance development in a cogeneration with biogas for H2 production by catalytic reforming

Hernández Rosales I.P., Fernández Madrigal A., García Serrano L., UNAM, MX

The main object of this research was carry out technically a mass and energy balances in an energy cogeneration plant with cattle excrement gas a fuel composed by biogas + natural gas. This fuel was [...]

Structural Analysis of Platinum Paladium Nanoparticles Supported on amorphous Silica by High Resolution Electron Microscopy

Castillo N., Diaz Barriga L., Pérez R., UNAM, MX

Bimetallic nanoparticles structures and properties are distinct from those of pure elemental clusters. Particularly nanoalloy clusters finely dispersed onto high surface area supports, play an important role in heterogeneous catalysis because the performance of a [...]

Remote Manipulation of a Robotic Arm by Using Infrared Sensors

Chávez Rodríguez N.E., Esquivel Villar J., UNAM, MX

This project consists in adapting a remote operation system for a robotic arm by using infrared sensors to control its movements. A personal com-puter was used to send instructions to the robotic arm, instead of [...]

Surface Plasmon Resonances of Metal Polyhedral Nanoparticles

González A.L., Noguez C., UNAM, MX

In this work, we show that it is possible to elucidate among different polyhedral shapes of silver nanoparticles of less than 10 nm, by studying their surface plasmon resonances. When a particle is excited by [...]

Preparation and Microstructural Characterization of Pt-Pd Bimetallic Catalysts Supported on TiO2

Castillo N., García Serrano L.A., Flores Sandoval C.A., Pérez R., UNAM, MX

Nanoparticles, specially metallic nanoparticles finely dispersed onto high surface area supports, play an important role in heterogeneous catalysis because the performance of a supported metal catalyst can be related to design, which is most crucial [...]
