Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
Encapsulation of resveratrol into Ca-alginate submicron particles
(Elsevier Sci Ltd, Oxford, 2015)
Resveratrol-loaded alginate submicron particles were prepared by emulsification followed by external gelation. Scanning electron microscopy analysis of the air-dried and freeze-dried submicron particles demonstrated their ...

(Springer, New York, 2018)
This paper presents a development of general regression neural network (a form of artificial neural network) models for the prediction of annual quantities of hazardous chemical and healthcare waste at the national level. ...
Cloud Point Phenomena in the (Aniline or N,N-Dimethylaniline plus Water) Solutions, and Cosolvent Effects of Liquid Poly(ethylene glycol) Addition: Experimental Measurements and Modeling
(Amer Chemical Soc, Washington, 2015)
In this work, liquid phase behavior (cloud point phenomena) was studied for two binary and four aqueous pseudobinary systems containing aniline or N,N-dimethylaniline and poly(ethylene glycol) 200 Or poly(ethylene glycol) ...
Influence of Chemically Modified Short Hemp Fiber Structure on Biosorption Process of Zn2+ Ions from Waste Water
(Korean Fiber Soc, Seoul, 2014)
Short hemp fibers, acquired as a waste from textile industry, were used as an efficient biosorbent for removal of zinc ions from polluted water. In order to obtain the material with better sorption properties, short hemp ...
Experimental investigation and thermodynamic prediction of the Au-Cu-Sb phase diagram
(Elsevier Science Sa, Lausanne, 2011)
Phase diagram of the ternary Au-Cu-Sb system was investigated experimentally by DTA and SEM-EDS methods and analytically by CALPHAD method. The liquids projection, invariant equilibrium, several vertical sections and ...

On the choice of optimal conformation in linear free-energy relationships. Reactivity of 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Rate constants for the esterification of eleven 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids with diphenyldiazomethane in ethanol at 30 degrees C were determined, and correlated with substituent constants using ...
Application of an integrated supercritical extraction and impregnation process for incorporation of thyme extracts into different carriers
(Handbook on Supercritical Fluids: Fundamentals, Properties and Applications, 2014)
Supercritical carbon dioxide (sc2) is known as a good solvent for a wide range of bioactive compounds from natural sources. Extraction of bioactive compounds from plant material using sc2 is a favorable technique for ...
