ZnO nanoparticles (nanZnO) and a zeolite-ZnO nanoparticles composite (Ze-nanZnO) were prepared and characterized. These materials were used for the removal of tartrazine from aqueous solutions by an adsorption-photocatalysis ...

Durante el siglo xix y las primeras décadas del xx, la investigación científica desarrollada en México giraba principalmente en torno al estudio de las plantas medicinales. Se analizan los instrumentos y técnicas utilizados ...

In the present work three different natural materials and their modifications were studied for fluoride removal from aqueous solutions. The materials employed were: clinoptilolite (C), montmorillonite (M) and pumice (P), ...

Aluminum, mercury, and iron have been found in high concentrations in various freshwater bodies around the world and have been shown to be very harmful contaminants to hydrobionts, causing metabolic dysfunction and damage ...

Currently, 84% of energy that is consumed in the world originates from fossil fuels, a non-renewable and rapidly depleting resource. In addition, the use of fuels derived from it results in environmental problems such as ...

It was studied the Aluminum Trifluoromethyl Sulfonate ((Al(OTf)3) as a very effective catalyst to polymerize Epoxidized Linseed Oil (ELO) in bulk, in a very wide range of temperatures, from room temperature (25°C) to the ...

tAdsorption isotherms for spray-dried tamarind seed mucilage were determined at 20, 30and 40◦C and fitted to GAB and Caurie sorption models. The sorption properties were esti-mated using Kelvin and Helsey equations and the ...

Study of the sensing parameters: sensibility, response and recuperation times to hexane vapors for layers of different thickness of poly(butadiene) + carbon black (CB) composites is presented. The results show that sensibility ...

A hybrid configuration for multicomponent thin film deposition by combining two laser ablation plasmas with one sputtering plasma is presented. This setup was used to deposit TiO2 thin films modified simultaneously with ...

In the present investigation, four macrophytes, namely Typha latifolia (L.), Lemna minor (L.), Eichhornia crassipes (Mart.) Solms-Laubach, and Myriophyllum aquaticum (Vell.) Verdc, were evaluated for their heavy metal (Cu, ...
