Swelling and thermodynamic studies of temperature responsive 2-hydroxyethyl methacrylate/itaconic acid copolymeric hydrogels prepared via gamma radiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were synthesized by gamma radiation induced radical polymerization. Swelling and thermodynamic properties of PHEMA and copolymeric ...
Investigation of the electrical behavior of some textile materials
(Elsevier, Amsterdam, 2007)
Some electrophysical properties of textile samples having different forms and raw material compositions were studied. For determining the electric resistance, a measuring device, based on the measurement of direct current ...
Effect of low-temperature plasma and chitosan treatment on wool dyeing with acid red 27
(John Wiley & Sons Inc, Hoboken, 2005)
This study examines in detail the influence of low-temperature plasma and biopolymer chitosan treatments on wool dyeability. Wool knitted fabrics were treated and characterized by whiteness and shrink-resistance measurements. ...
Nanomechanical properties evaluation of bioactive glass coatings on titanium alloy substrate
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
Bioinert metallic implants such as titanium and titanium alloys could be coated with bioactive materials with good adhesion to metal and which could be also bonded to the bone. In order to predict the mechanical behavior ...
Electrophoretic Deposition of Biocomposite Lignin/Hydroxyapatite Coatings on Titanium
(Walter de Gruyter Gmbh, Berlin, 2009)
In this work, electrophoretic deposition (EPD) was applied to obtain novel hydroxyapatite (HAP)/lignin (Lig) biocomposite coatings on titanium substrate. Nanosized hydroxyapatite powder, prepared by using the modified ...
Experimental determination and modelling of densities and excess molar volumes of ternary system (1-butanol + cyclohexylamine plus n-heptane) and corresponding binaries from 288.15 to 323.15 K
(Elsevier Science Bv, Amsterdam, 2009)
Experimental densities rho and excess molar volumes V-E of one ternary and three binary systems containing 1-butanol, cyclohexylamine and n-heptane at temperatures from 283.15 to 323.15 K are reported. Density measurements ...
Evaluation of the potential of periodically operated reactors based on the second order frequency response function
(Inst Chemical Engineers, Rugby, 2008)
A new, fast and easy method for analysing the potential for improving reactor performance by replacing steady state by forced periodic operation is presented. The method is based on Volterra series, generalized Fourier ...
Incorporation of poly(N-isopropylacrylamide)/chitosan microgel onto plasma functionalized cotton fibre surface
(Elsevier, Amsterdam, 2009)
In the present study, non-thermal plasma treatments using three different gases (air, nitrogen and argon) were used to activate the cotton surface for subsequent poly(N-isopropylacrylamide)/chitosan microgel (PN/CS) ...
The influence of steel surface modification by electrodeposited Zn-Fe alloys on the protective behaviour of an epoxy coating
(Elsevier Science Sa, Lausanne, 2003)
The electrochemical and transport properties of epoxy coatings electrodeposited on steel and steel modified by Zn-Fe alloys were investigated during exposure to 3% NaCl. The Zn-Fe alloys were deposited on steel surface ...
Thermal behaviour of mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalate ligands
(Elsevier, Amsterdam, 2004)
Thermal behaviour of a series of ternary Co(II), Ni(II) and Cu(II) complexes with terephthalate ion and some aromatic diamines has been studied by thermogravimetric and differential scanning calorimetric techniques. ...
