Immobilization of AgZnO photocatalyst in Poly(acrylic acid) matrix and their photocatalytic activity evaluation

Jasso-Salcedo A.B., Meimaroglou D., Camargo M., Hoppe S., Pla F., Escobar-Barrios V.A., IPICYT, MX

The Ag modified Zinc oxide (AgZnO) is a catalyst with increased photocatalytic activity used for degradation of dyes and several organic molecules, in aqueous solution, in contrast to pure ZnO. Nevertheless, its application at pilot [...]

Green Chemistry of Carbon Nanomaterials

Basiuk E.V., Basiuk V.A., Basiuk E.V., Basiuk V.A., Universidad Nacional Autonoma de Mexico, MX

The global trend of searching for ecologically friendly, ‘green’ chemical processes manifested itself in the chemistry of carbon nanomaterials, in particular, in the development of techniques for their chemical (both covalent and noncovalent) modification. Our [...]

Cu/TiO2-SiO2 Nanostructured Materials for Brain Cancer Treatment

Ortiz-Islas E., Guevara P., Gómez E., Monroy H., Novaro O., National Institute of Neurology and Neurosurgery, MX

In the present work, we are reporting the toxic effect to brain cancer cells exerted by copper complexes loaded (CC) on a binary oxide. For this purpose, the TiO2-SiO2 oxide was prepared using the sol-gel [...]

Fabrication and characterization of core-shell microspheres composed of pectin and arabinoxylans as controlled release systems for insulin

Díaz-Baca J., Martinez-Lopez A.L., Carvajal-Millan E., Pérez-López E., González-Ríos H., Balandrán-Quintana R., Rascón-Chu A., Centro de Investigacion en Alimentacion y Desarrollo A.C., MX

Currently incidence of diabetes is increasing worldwide very, WHO classifies it as an epidemic (WHO, 2012) and in Mexico is the leading cause of death (IMSS, 2012). The traditional form of insulin subcutaneous injection, is [...]

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 [...]

Synthesis of nanocrystalline cubic ZrO2:Mn2+ phosphors: Structural and luminescent properties

Fernández-Osorio A., Ramos-Olmos L., Julian C.F., Universidad Nacional Autonoma de Mexico, MX

Nanocrystalline cubic zirconia doped with manganese, solid solutions of Zr1-xMnxO2-x/2 (x=0, 0.1, 0.2 and 0.4), were prepared by the sol-gel method. The Rietveld refinement of the X-ray powder diffraction (XRD) profile of the samples confirms [...]

Thermodynamic Availability Sources from Inertial Energy

Celorio-Villasenor A., NATURBO Technology Centers, MX

Accomplishment: The development of a new cooling mechanism for gas turbines rotors (blades and disks). Cooling mechanism that utilizes a compressed liquid (hydrostatic) pressurized in rotating ducts or pipes with particular physical boundary conditions (no [...]

Pd/WO3-ZrO2 catalysts: synthesis, characterization and catalytic evaluation

Chen L.F., Ramirez Sebastian S.P., Wang J.A., Instituto Politecnico Nacional, MX

The present work aims at searching for new catalysts for n-heptane isomerization. Four WO3-ZrO2 oxides were prepared by varying WO3 content in 5, 10, 15 and 25 wt% using a sol-gel technique. The 1wt% Pd/WO3-ZrO2 [...]
