Characterization of glycidyl methacrylate based copolymers by inverse gas chromatography under finite surface coverage
(Wiley-VCH Verlag Gmbh, Weinheim, 2005)
Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl ...
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 ...
Solids residence time distribution in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2005)
Flowing solids residence time distribution in gas-flowing solids-fixed bed contactors was investigated using a tracer technique with a step signal as input. Particles of different color (all other properties being the same) ...
Corrosion studies on electrochemically deposited PANI and PANI/epoxy coatings on mild steel in acid sulfate solution
(Elsevier Science Sa, Lausanne, 2005)
The corrosion behavior of mild steel and mild steel covered by electrochemically deposited (a) polyaniline (PANI) film, (b) epoxy coating
and (c) PANI/epoxy coating system in 0.1 M sulfuric acid solution were investigated ...
Electrothermal desorption in an annular-radial flow - ACFC adsorber - Mathematical modeling
(Springer, New York, 2005)
A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic ...
Supercritical carbon dioxide essential oil extraction of Lamiaceae family species: Mathematical modelling on the micro-scale and process optimization
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
In this paper the essential oil supercritical carbon dioxide extraction from leaves of Lamiaceae family species was studied. Recent investigations of Lamiaceae family essential oil storage have shown that most of the oil ...
Experimental design approach in the synthesis of hydroxyapatite by neutralization method
(Elsevier, Amsterdam, 2005)
Physicochemical properties of hydroxyapatite (HAP) synthesized by neutralization method are heavily dependent on the process variables. A Plackett-Burman two-level experimental design was therefore, chosen to screen a large ...
UV-curable hyperbranched urethane acrylate oligomers containing soybean fatty acids
(Elsevier Science Sa, Lausanne, 2005)
Urethane acrylate resins based on partially modified aliphatic hyperbranched polyesters (HBP) have been synthesized. HBP of the second and the third generation were synthesized from 2,2-bis(hydroxymethyl)propionic acid and ...
Oxygen reduction reaction on Pt and Pt-bimetallic electrodes covered by CO - Mechanism of the air bleed effect with reformate
(Electrochemical Soc Inc, Pennington, 2005)
The oxygen reduction reaction (ORR) has been studied on CO-covered Pt(111), Pt(110), Pt-poly, Pt-Ru, Pt3Sn(111), and Pt3Sn( 110) electrodes in 0.5 M H2SO4 solution at temperatures varying between 298 and 333 K using the ...
Swelling and paracetamol release studies of poly(acrylamide-co-itaconic acid) hydrogels
(Elsevier, Amsterdam, 2005)
