Volumetric properties of the ternary system ethanol plus chloroform plus benzene at temperature range (288.15-313.15) K: Experimental data, correlation and prediction by cubic EOS
(Elsevier Science Bv, Amsterdam, 2007)
Densities p of the ternary system (ethanol + chloroform + benzene) and binaries (ethanol + chloroform) and (chloroform + benzene), have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15) K ...
Analysis of the composite and film hardness of electrodeposited nickel coatings on different substrates
(Elsevier Science Sa, Lausanne, 2008)
Fine-grained nickel thin films were electrodeposited from a self-made sulphamate-based electrolyte on different substrates: polycrystalline cold-rolled copper and single crystal silicon with two different orientations, ...
Phase-transformation kinetics in triphasic cordierite gel
(Cambridge Univ Press, New York, 2001)
A triphasic cordierite-type gel was prepared from silica sol, boehmite sol, and an aqueous solution of Mg(NO3)(2). 6H(2)O. The silica sol was obtained from water glass by the ion exchange method, while boehmite sol was ...
Removal of heavy metal ions from water by complexation-assisted ultrafiltration
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Toxic heavy metals in air, soil and water are global problems that are growing threat to the environment. Therefore, the removal and separation of toxic and environmentally relevant heavy metal ions are a technological ...
Electrochemical synthesis and characterization of hydroxyapatite powders
(Elsevier Science Sa, Lausanne, 2008)
Electrochemical synthesis of hydroxyapatite powders was performed galvanostatically from homogeneous solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of 0.25/0.25/0.15 ...
Microwave-assisted immobilization of lipase from Candida rugosa on Eupergit (R) supports
(Wiley, Hoboken, 2009)
BACKGROUND: Immobilization of lipase (triacylglycerol acylhydrolase EC 3.1.1.3) from Candida rugosa on Eupergite (R) C and Eupergit (R) C 250L was performed under microwave irradiation in order to reduce immobilization ...
Simplex optimization of artificial neural networks for the prediction of minimum detectable activity in gamma-ray spectrometry
(Elsevier, Amsterdam, 2006)
A three-layer feed-forward artificial neural network (ANN) with a back-propagation learning algorithm was used to predict the minimum detectable activity (AD) of radionuclides (Ra-226, U-238, U-235, K-40, Th-232, Cs-134, ...
Classification of soil samples according to geographic origin using gamma-ray spectrometry and pattern recognition methods
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Multivariate data analysis methods were used to recognize and classify soils of unknown geographic origin. A total of 103 soil samples were differentiated into classes, according to regions in Serbia and Montenegro from ...
Mechanism and kinetics of aging of high-strength Cu-5 wt.% Ni-2.5 wt.% Ti
(Carl Hanser Verlag, Munich, 2005)
Light and scanning electron microscopy (SEM), X-ray diffraction analysis, hardness and uniaxial tensile tests have been applied to study the mechanism and kinetics of aging of the Cu-5 wt.% Ni-2.5 wt.% Ti alloy under the ...
Predictive modeling of the mechanical properties of particulate hydroxyapatite reinforced polymer composites
(Wiley, Hoboken, 2002)
The influence of particle geometry and volume fraction on the mechanical properties of a hydroxyapatite (HAp) particulate reinforced polymer (poly-L-lactide and collagen) matrix composite was investigated through finite-element ...
