Volumetric properties of the binary methanol plus chloroform and ternary methanol plus chloroform plus benzene mixtures at (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K
(Amer Chemical Soc, Washington, 2007)
Densities rho of the ternary system of methanol + chloroform + benzene and binary mixture of methanol + chloroform have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric ...
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 ...
Antibacterial effect of silver nanoparticles deposited on corona-treated polyester and polyamide fabrics
(Wiley, Hoboken, 2008)
The possibility of using a corona treatment (electrical discharge at atmospheric pressure) for fiber surface activation, which can facilitate the loading of silver nanoparticles (NPs) from colloids onto the polyester (PES) ...
Bioreactor studies of native and tissue engineered cartilage
(IOS Press, Amsterdam, 2002)
Functional tissue engineering of cartilage involves the use of bioreactors designed to provide a controlled in vitro environment that embodies some of the biochemical and physical signals known to regulate chondrogenesis. ...
Dynamic mechanical analysis study of the curing of phenol-formaldehyde novolac resins
(Wiley, Hoboken, 2001)
The curing reaction of typical commercial phenol-formaldehyde novolac resins with hexamethylentetraamine (HMTA) was followed by dynamic mechanical analysis. The evolution of the rheological parameters, such as storage ...
Artificial neural network modelling of uncertainty in gamma-ray spectrometry
(Elsevier, Amsterdam, 2005)
An artificial neural network (ANN) model for the prediction of measuring uncertainties in gamma-ray spectrometry was developed and optimized. A three-layer feed-forward ANN with back-propagation learning algorithm was used ...
The thermal degradation of poly(diethyl fumarate)
(Elsevier Sci Ltd, Oxford, 2006)
The kinetics and mechanism of the thermal degradation of poly(diethyl fumarate) (PDEF) were studied by thermogravimetry, as well as by analysis of the thermolysis volatiles and polymer residue. The characteristic mass loss ...
Shrinkage properties of peroxide-enzyme-biopolymer treated wool
(Sage Publications Ltd, London, 2001)
Incorporating an enzyme in the alkaline peroxide treatment bath enhances wool wettability and the effectiveness of subsequently applied chitosan biopolymer. Wool whiteness is also significantly enhanced. Wool knitted fabric ...
Corrosion behavior and thermal stability of electrodeposited PANI/epoxy coating system on mild steel in sodium chloride solution
(Elsevier Science Sa, Lausanne, 2006)
The corrosion behavior, sorption characteristics and thermal stability of epoxy coatings electrodeposited on mild steel (MS) and mild steel with electrochemically deposited polyaniline (PANI) film were investigated in 3% ...
Osmotic coefficient of the ZnSO4(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2002)
The osmotic coefficient of ZnSO4(aq) has been measured at T = 298.15 K by the iso-piestic method, in the range of molalities from 1.3 to 3.0 mol . kg(-1), with KCl(aq) as the reference solution. Experimental data of osmotic ...
