Linseed oil miniemulsions stabilized by polyelectrolyte complex (gum arabic-chitosan)

Michel-Barba M.G., Espinosa-Andrews H., Centro de Investigación y Asistencia en Tecnología y Diseño del Estado de Jalisco, a.C., MX

An linseed oil miniemulsion was optimized using the microfludization process and finally stabilized by polyelectrolyte complexes formation. Emulsion preparation variables such as gum arabic/oil mass ratio (GA/O), oil volume fraction (), homogenization pressure and number [...]

PLGA and PLGA-PEG nanoparticles loaded with curcumin and their effect on aflatoxin B1 in vitro

Rivero-Gonzalez A., Ramirez-Noguera P., Universidad Nacional Autonoma de Mexico, MX

The aim of this study was to evaluate the effect of nanoparticles prepared with polylactic-co-glycolic acid (PLGA) and PLGA with polyethylene glycol (PLGA-PEG) loaded with curcumin in human hepatocytes exposed to aflatoxin B1 in vitro. [...]

Photocatalytic activity of commercial TiO2 oxides in the oxidation reaction of nitric oxide

Luévano-Hipólito E., Martínez-de la Cruz A., López-Gallegos V.M., Garza-del Bosque H., Universidad Autonoma de Nuevo Leon, MX

In this work will be explored the potential application of six commercial titanium oxides with different crystalline structures to act as an efficient photocatalyst in the conversion reaction of NOx gases to innocuous products as [...]

Improved impact toughness PVC composite with surface modified nano calcium carbonate, obtained by a novel physicochemical top-down manufacturing process

Acosta-Gonzalez G.E., Gutierrez-Antonio J., Perez-Rodriguez F., Nanomat SA de CV, MX

A novel top-down process was developed for produce surface modified calcium carbonate nanoparticles (NCC), 40 nm average size particles were functionalized in a water suspension by using energy from top-down physicochemical process. Well dry coated [...]

Retention of urea and caffeine on copper MOF

Zarate-Rubio J., Ortiz Elba, Solis Hugo, Medina-Velazquez D.Y., Loera-Serna S., Universidad Autonoma Metropolitana-Azcapotzalco, MX

The [Cu3(BTC)2] (BTC = 1,3,5-benzenetricarboxylate), also known as HKUST-1(or MOF-199), is one of the most cited metal-organic framework (MOF) because it has a large surface area, high pore volume, high chemical stability and also the [...]

Mexican natural zeolites: A low cost alternative to pigment retention

Loera-Serna S., Ortiz Elba, Solis Hugo, Medina-Velazquez D.Y., Universidad Autonoma Metropolitana-Azcapotzalco, MX

Several materials such as synthetic zeolites, clays and aluminas were studied as sorbent pigments. Majority of materials need pre-treatment to be capable to absorb molecules on the porous structure. These treatments include thermal treatment, washing [...]

The Use of Nano Fillers in Silicone Rubber Composites for High Voltage Insulators

Ramirez I., Instituto de Investigaciones Eléctricas, MX

Since some years ago, polymer compositions have been used for outdoor electrical insulation applications as an alternative to inorganic materials such as porcelain and glass. The organic compositions are based on silicone rubber (SiR) and [...]

Development and Characterization of an aqueous dispersion based nano zinc oxide for cosmetic application in sunscreens

Perez-Rodriguez F., Acosta-Gonzalez G., Gutierrez-Antonio J., Aguilera-Bustos M., Acosta-Armenta L., Nanomateriales, MX

Development of an additive based nanostructured zinc oxide nano through a grinding process1 and physicochemical surface functionalization allows the formation of a stable aqueous dispersion having high solids and thus, high capacity for absorption of [...]

Study of the photocatalytic oxidation mechanism of 1,3-dihydroxyanthraquinone using DFT methodology

Cortés-Romero C.M., Cuán A., Solís H., Universidad Autónoma de Querétaro, MX

Chemical degradation of organic pollutants present not only in water but also in air and earth, has become the target of industrial and academic groups due to the negative impact that they have to the [...]
