Determination of the diffusion coefficients in the ascorbic acid delivery from nanostructured-polyacrilamide hydrogels
(2006)
In this work the diffusional behavior of water and ascorbic acid (V-C) from a new crosslinked nanostructured polyacrylamide (polyAM) hydrogels is analyzed. The process involves the synthesis of slighlty crosslinked ...
Design of a drug delivery system based on poly(acrylamide-co-acrylic acid)/chitosan nanostructured hydrogels
(2007)
To obtain biodegradable materials for biomedical applications, new biopolymeric hydrogels based on blends of Polyacrylamide nanoparticles and chitosan have been prepared. In this work, we have studied the behavior of the ...
Determination of Cu in tequila by anodic stripping voltammetry
(2008)
Concentrations of metals such as copper in alcoholic beverages must be strictly regulated due to negative effects ranging from beverage spoilage and hazing, to sensorial and health consequences. In this paper, a voltammetric ...
Plasma enhanced modification of Xanthan and its use in Chitosan/xanthan Hydrogels
(2014)
This study reports the design and construction of a fluidized bed/non-equilibrium atmospheric-pressureplasma reactor. The mechanical design of the reactor was devised to modify chemically and physically the surface of ...

Identificación y valor nutricional de algunos materiales nativos de arándano (Vaccinium spp)
(2013)
The blueberry is a shrub of the family Ericaceae, genus Vaccinium. Its fruits are berries of dark, bluish or reddish coloration. Presents nutritional qualities and antioxidants which make it a fruit of high nutritional and ...
Integrating toxicity testing in the wastewater management of chemical storage terminals - A proposal based on a ten-year study
(ELSEVIER SCIENCE BVHolanda, 2011)
Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...

Machine learning is an area of Artificial Intelligence that can predict results from a large
set of data. Therefore, many areas are already benefiting from this new technology, such as credit
analysis companies that use ...
Modifying electronic properties of ICBA through chemical substitutions for solar cell applications
(2017-08-01)
Fullerene derivatives are the most widely used type of acceptor material in the organic solar cells (OSCs) active layers, but there are still some problems to be overcome, such as increased solubility and adjustment of the ...
