Analysis of chemical polymerization between functionalized MWCNT and poly(furfuryl alcohol) composite
In this study, the chemical interaction between functionalized carbon nanotuboes with carboxyl groups (CNT-f) and the subsequent addition of furfuryl alcohol (FA) and mixture with poly(furfuryl alcohol) (PFA) resin was ...
Electrochemical oxidation of wastewater containing aromatic amines using a flow electrolytic reactor
Aromatic amines are environmental pollutants and represent one of the most important classes of industrial and natural chemicals. Some types of complex effluents containing these chemical species, mainly those originated ...
Determination of Cr, Fe, Co, Ni, Cu, Zn, As and Pb in liquid chemical waste by energy dispersive X-ray fluorescence
A method for simultaneous determination of Cr, Fe, Co, Ni, Cu, Zn, As e Pb in liquid chemical waste using Energy Dispersive X-Ray Fluorescence (EDXRF) technique was evaluated. A small sample amount (200 mu L) was dried on ...
A comparative analysis of the chemical nature of defensive secretions of Gonyleptidae (Arachnida : Opiliones : Laniatores)
(Elsevier B.V., 2005-12-01)
The arachnids of the order Opiliones (harvestmen) produce substances used in defense. In the present paper, we analyzed 22 species of Gonyleptidae to explore the use of defensive substances in taxonomy and evolutionary ...

Shelf-life of chicken loaves
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-11-01)
This research was designed to study the elaboration of chicken loaf with ground meat. The products were elaborated in laboratory scale utilizing broiler meat bought at the market. The products were conditioned in vacuum-packages ...
Quantum chemical topological analysis of hydrogen bonding in HX…HX and CH3X…HX dimers (X = Br, Cl, F)
We present a systematic investigation of the nature and strength of the hydrogen bonding in HX···HX and CH3X…HX (X = Br, Cl and F) dimers using ab initio MP2/aug-cc-pVTZ calculations in the framework of the quantum theory ...
