Comparative study of phenolic compounds in different Brazilian rice (Oryza sativa L.) genotypes
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
This study was conducted to evaluate the natural variability of total, extractable and non-extractable phenolics in pigmented and non-pigmented rice genotypes (Oryza sativa L.) and to estimate whether the contents and ...
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 ...
Biobased composites from tannin-phenolic polymers reinforced with coir fibers
(ELSEVIER SCIENCE BV, 2010)
Tannin-phenolic polymers prepared using tannin, a macromolecule obtained from natural sources, were used in the preparation of composites reinforced with coir fibers. The composites based on tannin-phenolic polymers (50% ...
Sisal chemically modified with lignins: Correlation between fibers and phenolic composites properties
(ELSEVIER SCI LTD, 2008)
Sisal fibers have been chemically modified by reaction with lignins, extracted from sugarcane bagasse and Pinus-type wood and then hydroxymethylated, to increase adhesion in resol-type phenolic thermoset matrices. Inverse ...
Dispersing carbon nanotubes in phenolic resin using an aqueous solution
(2011-11-01)
The ability to control the carbon nanotube (CNT) dispersion in polymers is considered the key to most applications of nanotube/polymer composites. The carbon nanotube dispersion into water with different surfactants, as ...
Phenol-furfural resins to elaborate composites, reinforced with sisal fibers - Molecular analysis of resin and properties of composites
(JOHN WILEY & SONS INC, 2008)
Resol type resins were prepared in alkaline conditions (potassium hydroxide or potassium carbonate) using furfural obtained by acid hydrolysis of abundant renewable resources from agricultural and forestry waste residues. ...
Biobased composites from glyoxal-phenolic resins and sisal fibers
(ELSEVIER SCI LTD, 2010)
Lignocellulosic materials can significantly contribute to the development of biobased composites. In this work, glyoxal-phenolic resins for composites were prepared using glyoxal, which is a dialdehyde obtained from several ...
Impact of phenolic and polysaccharidic composition on commercial value of Argentinean Malbec and Cabernet Sauvignon wines
(Elsevier, 2012)
Knowledge of the chemical composition of wine and its association with the commercial value constitutes an
objective tool to assess quality and can be used as a marketing strategy. Phenolic compounds are very important
quality ...
From grape to wine: Changes in phenolic composition and its influence on antioxidant activity
(Elsevier, 2016-04)
The evolution of phenolic compounds and their relationship with the antioxidant capacity (AC) of samples taken along the winemaking process of three Vitis vinifera L. cv., Syrah, Merlot and Cabernet Sauvignon grown in ...
Phenolic Composition of the Brazilian Seedless Table Grape Varieties BRS Clara and BRS Morena
(Amer Chemical Soc, 2011-08-10)
The detailed phenolic composition (anthocyanins, flavonols, hydroxycinnamic acid derivatives, stilbenes, and flavan-3-ols) in the skin and flesh of the new BRS Clara and BRS Morena seedless table grapes has been studied ...
