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 ...
Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...

(Sage Publications Ltd, London, 2009)
The aim of this study was to investigate the potential use of recycled wool-based nonwoven material for removal of basic dyes C.I. Basic Yellow 28 and C.I. Basic Red 46 from aqueous solutions, To improve the sorption ...
Determination of multiple pharmaceutical classes in surface and ground waters by liquid chromatography-ion trap-tandem mass spectrometry
(Elsevier Science Bv, Amsterdam, 2009)
This paper describes development, optimization and application of analytical method for determination and reliable confirmation of nineteen pharmaceuticals from different therapeutic classes (antibiotics-beta-lactams. ...
The corrosion stability of epoxy cataphoretic coatings on steel and steel coated with zinc alloys
(Corrosion Protection: Processes, Management and Technologies, 2009)
An organic coating is frequently deposited on the top of the metallic coating in order to generate a corrosion resistant system by taking advantage of the good properties of the sublayer. In automotive industry steel is ...
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 ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
Lipase-catalyzed synthesis of biodiesel in solvent-free system with different acyl acceptors
(Elsevier Science Bv, Amsterdam, 2009)
