Removal of Cu(II) from aqueous solutions by using fluidized zeolite A beads: Hydrodynamic and sorption studies
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This study investigated potentials of fluidized bed systems with zeolite A beads for removal of heavy metal ions from aqueous solutions. Two commercial zeolite bead fractions (0.7 and 2.2 mm in diameter) were used, while ...
Hydrodynamic modeling of downward gas-solids flow. Part I: Counter-current flow
(Elsevier, Amsterdam, 2014)
The one-dimensional model of accelerating turbulent downward counter-current gas-solids flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. ...
Polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics fabricated by Spark Plasma Sintering: Densification and microstructure development
(Elsevier Sci Ltd, Oxford, 2014)
Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 ...
Particle characterization of polydisperse quartz filtration sand
(Elsevier Science Bv, Amsterdam, 2014)
In this paper, different methods for particle characterization were applied to 16 polydisperse fractions of quartz filtration sand obtained by sieving, with sieve diameters in the interval d(m) = 0359 to 2.415. For each ...
Solvent and Structure Effects on Electronic Absorption Spectra of the Isomeric Pyridinecarboxylic Acids
(Springer, New York, 2014)
Ultraviolet absorption spectra of three isomeric pyridinecarboxylic acids (picolinic, nicotinic, and isonicotinic acids) were measured in 18 various solvents, in the wavelength range from 200 to 400 nm. In order to analyze ...
Use of Mosses as Biomonitors of Major, Minor and Trace Element Deposition Around the Largest Thermal Power Plant in Serbia
(Wiley, Hoboken, 2014)
The survey results of an atmospheric deposition of major, minor and trace elements
using the moss biomonitoring technique are given for the vicinity of the largest
thermal power plant in Serbia. The mosses of genus ...
Electrooxidative Behavior of Arylazo Pyridone Dyes and Their Inclusion Complexes on Gold Electrode in 0.1 M NaOH
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The electrochemical behavior of six arylazo pyridone dyes classified to the substituents present at the phenylazo and 2-pyridone moiety and their 1:1 inclusion complexes with (2-hydroxypropyl)-beta-cyclodextrin was studied ...
Metal | polypyrrole battery with the air regenerated positive electrode
(Elsevier Science Bv, Amsterdam, 2014)
Recharge characteristics of the battery based on the electrochemically synthesized polypyrrole cathode and aluminum, zinc, or magnesium anode in 2 M NH4Cl are investigated. It is shown that polypyrrole electrode can be ...
Visible light-harvesting of TiO2 nanotubes array by pulsed laser deposited CdS
(Elsevier Science Bv, Amsterdam, 2014)
Titanium dioxide (TiO2) nanotubes arrays, obtained by anodization technique and annealing, were decorated with CdS using pulsed laser deposition method. Their structural, morphological and chemical characterization was ...
Immobilization of lipase on epoxy-activated Purolite((R)) A109 and its post-immobilization stabilization
(Elsevier Sci Ltd, Oxford, 2014)
In this study, Purolite (R) A109, polystyrenic macroporous resin, was used as immobilization support due to its good mechanical properties and high particle diameter (400 mu m), which enables efficient application in enzyme ...
