Solids flow pattern in gas-flowing solids-fixed bed contactors. Part II Mathematical modeling
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
In this paper a mathematical model for solids flow in gas-flowing solids-fixed bed contactors is developed. The presented four-parameter model assumes plug flow with axial dispersion in the dynamic, fast moving solids zone ...
Recycled-wool-based nonwoven material as a sorbent for lead cations
(Wiley, Hoboken, 2003)
The aim of this study was to investigate the sorption properties of a recycled-wool-based nonwoven material for lead cations. To improve sorption properties, the material was treated with low-temperature air plasma and/or ...
Wall-to-bed heat transfer in vertical hydraulic transport and in particulate fluidized beds
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
Wall-to-bed heat transfer in hydraulic transport and in particulate fluidized beds of spherical particles was studied. Experiments were performed by spherical glass particles of 0.80-2.98 mm in diameter with water in a ...
Synthesis and characterization of interpenetrating polymer networks with hyperbranched polymers through thermal-UV dual curing
(Elsevier Science Sa, Lausanne, 2008)
The aim of this study was to investigate the possibility of using acrylated hyperbranched polyesters (HBP) as UV curable component in dual curing automotive applications. Dual curing is one of possible ways to obtain fast ...
Substituent and solvent effects on the UV/vis absorption spectra of 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-eyano-2-pyridones
(Elsevier Science Bv, Amsterdam, 2006)
Absorption spectra of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones have been recorded in 12 protic and aprotic solvents in the range 200-600 nm. The effects of substituents on the absorption ...
Ionization energies of hypervalent Li2F, Li2Cl and Na2Cl molecules obtained by surface ionization electron impact neutralization mass spectrometry
(John Wiley & Sons Ltd, W Sussex, 2003)
Ionization energies of hypervalent Li2F, Li2Cl and Na2Cl molecules detected by surface ionization electron impact neutralization mass spectrometry are reported. The ionization energies were 3.78 +/- 0.2 eV for Li2F, 4.93 ...
Emulsion stability evaluation using fractal dimensions approach
(8th Conference of the Yugoslav Materials Research Society, 2007)
There are many developed strategies for evaluating emulsion stability, aimed at determining the life circle of emulsions. Most of them are based on rheological properties of emulsions. There are, however, very few based ...
Static holdup in Gas - Flowing solids - Fixed bed contactors
(Elsevier Science Bv, Amsterdam, 2009)
Static holdup was investigated experimentally and theoretically in gas - flowing solids - fixed bed bench-scale contactors. Diverse packing elements were used: Raschig rings, ceramic beads, crushed stone and glass beads. ...
Solvent effects on the structure-activity relationship of pharmacological active 3-substituted-5,5-diphenylhydantoins
(Springer/Plenum Publishers, New York, 2007)
Absorption spectra of eight 3-substituted-5,5-diphenylhydantoins have been recorded in fourteen solvents in the range 200-100 nm. The effect of solvent dipolarity/polarizability and solvent/solute hydrogen bonding interactions ...
Antifungal efficiency of corona pretreated polyester and polyamide fabrics loaded with Ag nanoparticles
(Springer, New York, 2009)
This study discusses the possibility of using the corona (electric discharge at atmospheric pressure) treatment for fiber surface activation that can facilitate the loading of Ag nanoparticles (NPs) from colloids onto the ...
