A universal transportation model for reverse osmosis systems
(Computers & Chemical Engineering, 2021)
This paper presents a new transport model for reverse osmosis (RO) systems, which combines irreversible thermodynamics, together with solution-diffusion theory. The simplifications adopted by the classical theory for ...
Mechanism and kinetics of nanosilver formation by ultrasonic spray pyrolysis progress report after successful up-scaling (Part 2)
(Metall, 2011)
In 2006 the authors presented in Metall [Vol. 60, No. 6, pp. 377-382] first results on this promising new technology for nanopowder synthesis. Since then a significant improvement and up-scaling took place at IME Aachen ...
Economic insight into energents consumption in copper melting and refining plants of Serbia using the method of reduction to conditional fuel (coal equivalent)
(Editura Stiintifica Fmr, Bucharest, 2011)
Copper melting and refining include consumption of significant quantities of almost all kinds of conventional energents. Consumption is high in nominal as well as in specific form. This paper presents the analysis of ...
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, ...
Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands
(Elsevier, Amsterdam, 2011)
A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,2'-dipyridylamine (dipya), 2,2'-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid ...
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 ...
