Solvent and Structural Effects on the UV-Vis Absorption Spectra of Some 4,6-Disubstituted-3-Cyano-2-Pyridones
(Springer/Plenum Publishers, New York, 2012)
A series of 4,6-disubstituted-3-cyano-2-pyridones was synthesized and their UV-Vis absorption spectra were recorded in the region 200-600 nm in the set of selected solvents. The effects of solvent dipolarity/polarizability ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier Science Sa, Lausanne, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
Equilibrium and kinetics study on hexavalent chromium adsorption onto diethylene triamine grafted glycidyl methacrylate based copolymers
(Elsevier Science Bv, Amsterdam, 2012)
Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Approaches to mathematical modeling of tissue engineering systems
(Cell and Tissue Engineering, 2012)
Tissue engineering (TE) is one of the new strategies aiming to address the problem of tissue failure by in vitro cultivation of functional tissue equivalents (please see the Chapter 1). Ideally, engineered tissues can serve ...
Cell and tissue engineering
(Cell and Tissue Engineering, 2012)
"Cell and Tissue Engineering" introduces the principles and new approaches in cell and tissue engineering. It includes both the fundamentals and the current trends in cell and tissue engineering, in a way useful both to a ...
Isolation of Hemoglobin from Bovine Erythrocytes by Controlled Hemolysis in the Membrane Bioreactor
(Springer, New York, 2012)
In this work, we describe an optimized procedure based on gradual hemolysis for the isolation of hemoglobin derived from bovine slaughterhouse erythrocytes in a membrane bioreactor. The membrane bioreactor system that ...
In vitro control of multiplication of some food-associated bacteria by thyme, rosemary and sage isolates
(Elsevier Sci Ltd, Oxford, 2012)
Antibacterial activity of thyme, rosemary and sage isolates obtained by supercritical fluid extraction and hydrodistillation was investigated on Geobacillus stearotermophillus, Bacillus cereus, Bacillus subtilis var. niger, ...
Industrial use of a new ultrasound spray for coolin and wet gas treatment in the pyrometallurgical processes
(141st Annual Meeting and Exhibition, TMS 2012, 2012)
This paper presents the results of a new industrial use the ultrasonic spray for gas cooling from sulphide copper concentrate roasting in the fluo solid reactor and the results of wet gas treatment (washing) in the scrubber ...
Removal of Mg from spring water using natural clinoptilolite
(Mineralogical Soc, Twickenham, 2012)
Natural zeolitic tuff from Brus (Serbia) consisting mostly of clinoptilolite (about 90%) has been investigated for the reduction of the Mg concentration in spring water. The sorption capacity of the zeolite is relatively ...
