Experimental determination and modeling of densities and refractive indices of the binary systems alcohol plus dicyclohexylamine at T = (288.15-323.15)K
(Elsevier, Amsterdam, 2011)
The experimental density rho and refractive index n(D) data have been determined for the systems of dicyclohexilamine with 1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol, in the temperature range (288.15, 293.15, ...
Nonlinear Frequency Response Analysis of the Ferrocyanide Oxidation Kinetics. Part I. A Theoretical Analysis
(Amer Chemical Soc, Washington, 2011)
In this work, a nonlinear frequency response (NLFR) analysis was used for a first time in a theoretical study of nonlinear behavior of electrochemical (EC) ferrocyanide oxidation as a simple model reaction. Analytical ...
Comparison of structural, textural and thermal characteristics of pure and acid treated bentonites from Aleksinac and Petrovac (Serbia)
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Bentonite samples collected from vicinity of Petrovac and Aleksinac were treated with different sulfuric acid molarities. Acid attack dissolved the octahedral sheets by interlayer and edge attack. The effects of the H2SO4 ...
The EIS investigation of powder polyester coatings on phosphated low carbon steel: The effect of NaNO2 in the phosphating bath
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of different type of iron-phosphate coatings on corrosion stability and adhesion characteristic of top powder polyester coating on steel was investigated. Iron-phosphate coatings were deposited on steel in the ...
Ionization energies of K2X (X=F, Cl, Br, I) clusters
(Wiley, Hoboken, 2011)
The electronic structure and properties of dipotassiummonohalides are important for understanding the unique physical and chemical behavior of MnX systems. In the present study, K2X (here X=F, Cl, Br, I) clusters were ...
High-temperature deformation behaviour of Ti3Al-11Nb intermetallic
(Carl Hanser Verlag, Munich, 2011)
A mechanism of high-temperature plasticity has been studied in terms of stress exponent and activation energy for deformation. A Ti3Al-based intermetallic was processed by hot-rolling in the two-phase field to accomplish ...
Silver nanoparticles encapsulated in glycogen biopolymer Morphology, optical and antimicrobial properties
(Elsevier Sci Ltd, Oxford, 2011)
The glycogen biopolymer from the bovine liver has been used as stabilization agent for the growth of silver nanoparticles The samples with various contents of silver were prepared by two different procedures that include ...
Carbon Monolith Surface Chemistry Influence on the Silver Deposit Amount and Crystallite Size
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
The surface of carbon monolith (CM) was chemically treated in order to obtain antibacterial filters with silver deposit for water treatment. The chemical treatment involved submerging the as-received CM in HNO(3), KOH and ...
Removal of lead from water by amino modified multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2011)
Pristine, oxidized, ethylenediamine, diethylenetriamine and triethylenetetramine modified multi-walled carbon nanotubes (raw-MWCNT, o-MWCNT, e-MWCNT, d-MWCNT and t-MWCNT, respectively) were employed as adsorbents in order ...
Influence of process parameters on the photodegradation of synthesized azo pyridone dye in TiO2 water suspension under simulated sunlight
(Taylor & Francis Inc, Philadelphia, 2011)
Photocatalytic degradation of synthesized azo pyridone dye (5-(4-sulpho phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridone), in aqueous solutions by simulated sunlight in the presence of commercial TiO2, Aeroxide P25, was ...
