Biologically active fibers based on chitosan-coated lyocell fibers
(Elsevier Sci Ltd, Oxford, 2009)
The possibilities of obtaining biologically active cell ulose-chitosan fibers were examined. An effective two-stage method was developed. The first stage involves the formation of dialdehyde cellulose by the potassium ...
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% ...
Prediction of thermal shock behavior of alumina based refractories: Temperature difference, fracture resistance parameters and water quench
(Trans Tech Publications Ltd, Durnten-Zurich, 2001)
In this paper temperature difference and fracture resistance parameters were used for prediction of thermal shock behavior of the samples. Materials were alumina based commercial refractories with different content of Al2O3 ...
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 ...
Swelling behaviour and paracetamol release from poly(N-isopropylacrylamide-itaconic acid) hydrogels
(Springer, New York, 2009)
Copolymer hydrogels of N-isopropylacrylamide and itaconic acid (IA), crosslinked with N,N'-methylenebisacrylamide, were prepared by radical copolymerization. These hydrogels were investigated with regard to their composition ...
Synthesis and characterization of biodegradable poly(butylene succinate-co-butylene fumarate)s
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A series of aliphatic biodegradable polyesters modified with fumaric residues was synthesized by transesterification in the melt of dimethyl succinate, dimethyl fumarate and 1,4-butanediol. The amount of unsaturation, ...
Characterization of microstructural changes in an Al-6.8 wt.% Mg alloy by electrical resistivity measurements
(Elsevier Science Sa, Lausanne, 2008)
Microstructural changes in an AlMg6.8 alloy after different thermo mechanical (TMT) and sensitization treatments were investigated by electrical resistivity measurements. The electrical resistivity was most affected by the ...
Electrochemical deposition and corrosion stability of Zn-Co alloys
(Springer, New York, 2009)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using anodic linear sweep voltammetry for phase structure determination, scanning electron microscopy for surface morphology ...
Solid acids as catalysts for biodiesel synthesis
(Heterogeneous Catalysts: Design, Applications and Research Insights, 2016)
Increased environmental concern and awareness of limited reserves of fossil fuels gave a great importance to alternative and renewable energy sources over the past couple decades. An excellent substitute for mineral diesel ...
Osmotic coefficient of the ZnCl2(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2003)
The osmotic coefficient of ZnCl2(aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4) mol . kg(-1) with KCl(aq) as the reference solution. The available literature ...
