Moisture absorption capacity of polyamide 6,6 fabrics surface functionalised by chitosan-based hydrogel finishes
(Elsevier Science Sa, Lausanne, 2011)
The present study aims at investigating the moisture absorption capacity of polyamide 6,6 fabrics when their surface is functionalised by chitosan-based hydrogels. For the finishing procedure, bulk hydrogels of chitosan ...
Complexation of amidated pectin with poly(itaconic acid) as a polycarboxylic polymer model compound
(Elsevier Sci Ltd, Oxford, 2011)
Complexes based on amidated pectin (AP) and poly(itaconic acid) (PIA) were prepared by casting films from solutions of AP and PIA in different ratios with the pectin amount ranging from 10% to 90% by mass. The complexes ...
Electrochemical characterization of polyaniline electrode in ammonium citrate containing electrolyte
(Elsevier Science Sa, Lausanne, 2011)
Polyaniline electrode (PANI) was formed electrochemically at graphite electrode. Electrochemical polymerization was performed at constant current density of 2.0 mA cm(-2) from aqueous solution of 1.0 mol dm(-3) HCl with ...
Thermomechanical Properties and Cavitation Resistance of a High-Alumina Low-Cement Castable
(Wiley-Blackwell, Malden, 2011)
The purpose of this study was to investigate the mechanical properties and level of cavitation damage to alumina-based low-cement castable. The effects of temperature treatment on some of the mechanical properties (strength, ...
Glass transition and polymer dynamics in silver/poly(methyl methacrylate) nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Dynamic mechanical-thermal analysis (DMTA), differential scanning calorimetry (DSC), thermally stimulated depolarization currents (TSDC) and, mainly, broadband dielectric relaxation spectroscopy (DRS) were employed to ...
Isopiestic determination of the osmotic and activity coefficients of the {yKCl + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
The osmotic coefficients of aqueous mixtures of KCl and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method over the range of ionic strengths from (2.3700 to 11.250) mol . kg(-1) ...
A highly efficient diastereoselective synthesis of alpha-isosalicin by maltase from Saccharomyces cerevisiae
(Elsevier Sci Ltd, Oxford, 2011)
In this report, alpha-isosalicin, a potent anticoagulant and skin whitening agent, was synthesized by a highly efficient chemoselective and diastereoselective reaction, catalyzed by maltase from bakers' yeast (Saccharomyces ...
Deciduous tree leaves in trace elements biomonitoring: A contribution to methodology
(Elsevier Science Bv, Amsterdam, 2011)
Air quality biomonitoring using plant leaves has been widely applied to assess the effects of atmospheric pollution. Although practiced for many years, it has not given completely satisfactory data, due to different and ...
Volumetric Properties and Spectroscopic Studies of Pyridine or Nicotine Solutions in Liquid Polyethylene Glycols
(Amer Chemical Soc, Washington, 2011)
Densities and molar excess volumes of the solutions of pyridine or nicotine in liquid polyethylene glycol, PEG200 and PEG400, have been determined at several temperatures. The experimental molar excess volumes are negative, ...
The effect of deposition temperature on the surface coverage and morphology of iron-phosphate coatings on low carbon steel
(Elsevier, Amsterdam, 2011)
The influence of deposition temperature and concentration of NaNO2 in the phosphating bath on the surface morphology and coverage of iron-phosphate coatings on low carbon steel was investigated. The phosphate coatings were ...
