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) ...
Applications of non-linear frequency response for investigation of adsorption systems
(Soc Chemists Technologists Madeconia, Skopje, 2009)
Two main directions of application of nonlinear frequency response and the concept of higher order frequency response functions (FRFs) in investigation of adsorption systems are presented, one for development of novel ...
Alumina/silica supported K2CO3 as a catalyst for biodiesel synthesis from sunflower oil
(Elsevier Sci Ltd, Oxford, 2009)
The new type of catalyst for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as active component on alumina/silica support was synthesized using sol-gel method. Corresponding catalyst (xerogel) was prepared ...
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 ...
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 ...
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 ...
Acceptability of Residual Stresses Measurement Methods of Butt Weldments and Repairs
(Strojarstvo, 2009)
The joints made by fusion of materials are exposed to the influence of residual stresses induced by welding thermal cycles. Residual stresses were measured on butt welded plates made of NIOMOL 490K, before and after ...
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 ...
Linear free energy relationships of the H-1 and C-13 NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones
(Elsevier Science Bv, Amsterdam, 2009)
Linear free energy relationships (LFER) were applied to the H-1 and C-13 NMR chemical shifts in 3-cyano-4(substituted phenyl)-6-phenyl-2(1H)pyridones. The correlation analysis for the substituent-induced chemical shifts ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j (D) ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
