Development of carbon fiber/phenolic resin prepregs modified with nanoclays
(Sage Publications Ltd, 2015-06-15)
This work is focused on the study of the main variables involved in the development of phenolic/carbon prepregs and how these variables are affected by the incorporation of nanoclays. For this, phenolic resin was obtained ...
Antioxidant Properties and Total Phenolic Content of Eight Salvia Species from Turkey
(Sociedad de Biología de Chile, 2009)
Characterization of CuO/ Al2O3 catalysts used in the oxidation of phenol solutions
(Springer, 2003-07-11)
Two CuO/gAl2O3 catalysts were synthesized at different calcinations temperatures and used for the oxidation of phenol solutions. Deactivation is due to leaching of the active phase and deposition of carbonaceous material.
Impact of berry size at harvest on red wine composition: a winemaker's approach
(John Wiley and Sons Ltd, 2020)
Effect of phenols on the potentiometric response of a nitrate-ion-selective electrode
(Academic Press Inc., 2003)
The effect of phenols containing different electron-withdrawing substituents on the potentiometric responses of several liquid PVC membranes containing the complex trioctylmethylammonium-nitrate, TOMA+NO3 -, is analyzed. ...
Investigation of the mass transfer processes during the desalination of water containing phenol and sodium chloride by electrodialysis
(ELSEVIER SCIENCE BV, 2008)
Oxidation processes are used in wastewater treatment when conventional processes are not effective due to the presence of recalcitrant organic contaminants, like phenol. However, the presence of ionic compounds associated ...
Inhibited phenol ionization in reverse micelles: Confinement effect at the nanometer scale
(Wiley VCH Verlag, 2012-01)
We found that the absorption spectra of 2-acetylphenol (2-HAP), 4-acetylphenol (4-HAP), and p-nitrophenol (p-NPh) in water/sodium 1,4-bis(2-ethylhexyl)sulfosuccinate (AOT)/n-heptane reverse micelles (RMs) at various W 0 ...
Viscoelastic Behavior of Multiwalled Carbon Nanotubes into Phenolic Resin
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2013-07-01)
Nanostructured polymer composites have opened up new perspectives for multi-functional materials. In particular, carbon nanotubes (CNTs) have the potential applications in order to improve mechanical and electrical performance ...
Phenolic compounds from nuts: Extraction, chemical profiles, and bioactivity
(American Chemical Society, 2020-01)
Nuts contain a vast array of phenolic compounds having important biological properties. They include substances allocated into the five major groups named phenolic acids, flavonoids, tannins, phenolic lignans, and stilbene ...
Method for phenol recovery from “alperujo”: numerical optimization and predictive model
(Springer, 2019-08)
“Alperujos” of Arbequina olives harvested in 2010 and 2011 and of Nevadillo olives in 2012 were evaluated in order to reduce their pollutant load by recovering the phenols with antioxidant properties. First, three successive ...
