Using chitosan as a nucleation agent in thermoplastic foams for heavy metal adsorption
(2009)
Summary: Thermoplastics/chitosan-powder composite foams were prepared by extrusion using azodicarbonamide (ACA) as chemical blowing agent. The effect of chitosan content on morphology (cell size, nucleation density and ...
Thermoluminescence properties of undoped and Tb3+ and Ce3+ doped YAG nanophosphor under UV-, X- and ?-ray irradiation
(2007)
The thermoluminescence (TL) properties of undoped, Ce3+ and Tb3+ doped Y3Al5O12 (YAG) nanocrystals under UV-, X- and ?-rays irradiation is reported. The TL signal of undoped and doped samples indicates a high sensitivity ...
Endosulfan increases seric interleukin-2 like (IL-2L) factor and immunoglobulin M (IgM) of Nile tilapia (Oreochromis niloticus) challenged with Aeromona hydrophila
(2013)
Eight species of the genus Neogonodactylus have been reported from the eastern Pacific. Up to now, only three of these species have been collected in Mexican waters: Neogonodactylus stanschi (Schmitt, 1940), N. lalibertadensis ...
Electrostatic effects on the polymerization of vinyl acetate in three-component anionic microemulsions
(1999)
The polymerization of vinyl acetate (VA) in three-component microemulsions stabilized with Aerosol OT is examined as a function of pH. To investigate the role of electrostatic effects on the polymerization kinetics, two ...
Mollusks associated to the coral reefs of Tenacatita, Jalisco, in the central Mexican Pacific [Moluscos asociados al arrecife coralino de Tenacatita, Jalisco, en el Pacífico central mexicano]
(2013)
An analysis of the most common species of mollusks of the coral reef of Tenacatita, Jalisco, in the central Mexican Pacific is presented. The study includes species found both in the reef structure as well as in the ...
Downregulation of inducible nitric oxide synthase (iNOS) expression is implicated in the antiviral activity of acetylsalicylic acid in HCV-expressing cells
(2014)
Previously, we described that acetylsalicylic acid (ASA) decreases HCV expression, but the mechanisms involved have not been clearly established. We evaluated the participation of inducible nitric oxide synthase (iNOS) in ...
Enzymatic and fungal treatments on sugarcane bagasse for the production of mechanical pulps
(2004)
Crude ligninolytic enzyme extracts from Phanerochaete chrysosporium fungi were applied to sugarcane bagasse, prior to thermomechanical (TMP) and chemithermomechanical pulping (CTMP), and their properties were compared with ...
Phase behavior of the Pluronic P103/water system in the dilute and semi-dilute regimes
(2009)
The detailed temperature-composition phase diagram of the P103/water system in the dilute and semidilute regions is reported here using density and ultrasound velocity measurements, differential scanning calorimetry (DSC), ...
Resin Replica in Enamel Deproteinization and its Effect on Acid Etching
(2010)
Purpose: The goal of this in vitro study was to identify the topographical features of deproteinized (NaOCl) and etched with phosphoric acid (H3PO4) enamel surface, compared to phosphoric acid surface alone with a Resin ...
