Sustainability Stations

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 [...]

Solar automated greenhouse

Rabago F., de Santago E., Moncada J.I., Universidad Autonoma de San Luis Potosi, MX

In this work we presente the results obtained with a electronic circuit to control temperature, water, humidity and fertilizer of plants in a greenhouse. Different sensors were located in the greenhouse and electrovalves were activated [...]

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 [...]

Study of synergistic interactions between SiO2 nanoparticles and CTAB in the presence of NaCl: relationships with the formation and stabilization of hexadecane-in-water emulsions

Fouconnier B., Román-Guerrero A., Vernon-Carter J., Universidad Veracruzana, MX

The synergistic interactions between silica (SiO2) nanoparticles and a surfactant cetyltrimethylammonium bromide (CTAB) on the shear viscoelastic properties of the hexadecane-water (H/W) interfacial films as well as the formation and stability of emulsions were investigated. [...]

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 [...]

Metal-Oxide-Semiconductor Structures with Two and Three-Region Gate Dielectric Containing Silicon Nanocrystals: Structural, Infrared and Electrical Properties

Mateos D., Arias A., Nedev N., Curiel M., Dzhurkov V., Manolov E., Nesheva D., Contreras O., Valdez B., Bineva I., Raymond O., Siqueiros J.M., Autonomous University of Baja California, MX

MOS structures with two and three-region gate dielectrics containing Si nanocrystals are prepared and characterized by TEM, IR spectroscopy and electrical measurements. c Si/SiO2 containing Si NCs/SiO2/Al structures were obtained by high temperature annealing of [...]

Chemical Synthesis of Graphene Nanoribbons

Hernández-Arriaga D., González-González F.J., Segura-Cárdenas E., Reyes-Reyes M., López-Sandoval R., Universidad Autonoma de San Luis Potosi, MX

Carbon Nanotubes (CNTs) have been the reason of studies since they were discovered in 1991 and now the new innovator material is Graphene. Geim and Novoselov achieved a single sheet of Graphene. The importance of [...]

Copper complexes loaded on nanostructured TiO2 materials as citotoxic agents of cancer cells

Lopez T., Guevara P., Gómez E., Instituto Nacional de Neurologia y Neurocirugia, MX

In the present work ammonium tetrachlorocuprate (II) and copper (II) chloride were loaded on nanostructured mesoporous titania for determinate their anticancer properties. Copper-TiO2 materials were prepared using the sol-gel technology. Characterization of Copper complexes and [...]
