Experimental determination and modeling of densities and refractive indices of the binary mixtures of dimethylphthalate (or dimethyladipate)+1-butanol, or+2-butanol, or+2-butanone at T=(288.15-323.15) K
(Elsevier Science Bv, Amsterdam, 2012)
The experimental density rho and refractive index n(D) of the six binary mixtures of dimethylphthalate and dimethyladipate with 1-butanol, 2-butanol and 2-butanone have been determined. All measurements of rho and n(D) ...
Synthesis, structure and solvatochromic properties of some novel 5-arylazo-6-hydroxy-4-phenyl-3-cyano-2-pyridone dyes
(Springeropen, London, 2012)
Background: A series of some novel arylazo pyridone dyes was synthesized from the corresponding diazonium salt and 6-hydroxy-4-phenyl-3-cyano-2-pyridone using a classical reaction for the synthesis of the azo compounds. ...
Development and characterization of thermosensitive hydrogels based on poly(N-isopropylacrylamide) and calcium alginate
(Wiley, Hoboken, 2012)
This work refers to the synthesis and characterization of thermosensitive hydrogels based on interpenetrating polymer networks (IPNs) of poly(N-isopropylacrylamide) (PNIPAAm) and calcium alginate in the form of films. The ...
Substituent and solvent effects on intramolecular charge transfer of 5-arylidene-2,4-thiazolidinediones
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The absorption spectra of twelve 5-arylidene-2,4-thiazolidinediones were recorded in twenty one solvents in the range from 300 to 600 nm. The effect of specific and non-specific solvent-solute interactions on the absorption ...
The kinetics of the hydrogen oxidation reaction on WC/Pt catalyst with low content of Pt nano-particles
(Elsevier Science Sa, Lausanne, 2012)
The catalytic activity of WC/Pt electrocatalysts towards hydrogen oxidation reaction (HOR) in acid solution was studied. Tungsten carbide (WC) prepared by polycondensation of resorcinol and formaldehyde in the presence of ...
Formation of nano-plate silver particles in the presence of polyampholyte copolymer
(Elsevier Science Bv, Amsterdam, 2012)
Poly(2-(dimethylamino)ethyl methacrylate-co-acrylic acid) polyampholyte copolymers were synthesized by radical polymerization of the co-monomers in different molar ratios (2-1, 1-1 and 1-2). The water solutions of the ...
Microwave-assisted polyol synthesis of carbon-supported platinum-based bimetallic catalysts for ethanol oxidation
(Springer, New York, 2012)
High surface area carbon-supported Pt, PtRh, and PtSn catalysts were synthesized by microwave-assisted polyol procedure and tested for ethanol oxidation in perchloric acid. The catalysts were characterized by thermogravimetric ...
Structure-Retention Relationship Study of HPLC Data of Antiepileptic Hydantoin Analogues
(Bentham Science Publ Ltd, Sharjah, 2012)
In the study, 18 antiepileptic hydantoin analogues were investigated by means of reversed-phase HPLC on C-18 stationary phase and eluent acetonitrile-water. Quantitative structure-retention relationship (QSRR) study has ...
Improved Covalent Immobilization of Horseradish Peroxidase on Macroporous Glycidyl Methacrylate-Based Copolymers
(Springer, New York, 2012)
A macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate, poly(GMA-co-EGDMA), with various surface characteristics and mean pore size diameters ranging from 44 to 200 nm was synthesized, modified ...
Covalently immobilized lipase catalyzing high-yielding optimized geranyl butyrate synthesis in a batch and fluidized bed reactor
(Elsevier, Amsterdam, 2012)
Three commercially available polymers (Sepabeads (R) EC-EP, Sepabeads (R) EC-HA and Purolite (R) A-109) were tested for potential application as supports for covalent immobilization of lipase from Candida rugosa by analyzing ...
