Electrothermal desorption in an annular-radial flow - ACFC adsorber - Mathematical modeling
(Springer, New York, 2005)
A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic ...
Properties of dispersion-hardened copper made by internal oxidation of prealloyed copper powder containing 2.5wt. % Al
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Prealloyed copper powder containing 2.5wt. %Al was processed in a planetary ball mill to evaluate matrix hardening due to formation of Al2O3 particles in situ by internal oxidation. After milling, the powders were heat ...
Synthesis of nanostructured boehmite powder by sol-gel method from industrial Na-aluminate solution
(Techna Srl, Faenza, 2003)
Supersaturated Na-aluminate solution from KAP's Alumina plant Bayer process was chosen, as a precursor to synthesize low sodium content nanostructured boehmite powder. Firstly, the solution, was neutralized with strong ...
Enzymatic conversion of sunflower oil to biodiesel in a solvent-free system: Process optimization and the immobilized system stability
(Elsevier Sci Ltd, Oxford, 2009)
The feasibility of using the commercial immobilized lipase from Candida antarctica (Novozyme 435) to synthesize biodiesel from sunflower oil in a solvent-free system has been proved. Using methanol as an acyl acceptor and ...
Study of the kinetics and the influence of Bi-irr, on formic acid oxidation at Pt2RU3/C
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HCIO4 solutions was examined on thin film Pt2RU3/C electrode. XRD pattern revealed that Pt2RU3 alloy consisted of the solid solution of Ru in Pt and the small amount of Ru ...
The diffusion of water in poly(ditetrahydrofurfuryl itaconate)
(Elsevier Sci Ltd, Oxford, 2005)
The diffusion of water into solid poly(ditetrahydrofurfuryl itaconate) (PDTFI) films and in analogous polymer solutions was measured. Diffusion into solid PDTFI films on a glass support was measured in three solutions of ...
Estimate of Si3N4 diffusion into Cu based filler metal
(Elsevier Science Ltd, 2000)
The diffusion phenomena occurring at the boundary between Si3N4 and active Cu based filler metal during Si3Nn/metal joining are discussed as a part of the general theory of reaction layer growth. The mechanism of reaction ...
Lipase-catalyzed synthesis of biodiesel in solvent-free system with different acyl acceptors
(Elsevier Science Bv, Amsterdam, 2009)
Chain conformational statistics and mechanical properties of elastomer composites
(Progress in Advanced Materials and Processes: Proceedings of the Fifth Jugoslav Materials Research Society, YUCOMAT V, 2004)
A new equation of state for elastomer network under constrains due to fillers has been proposed and verified for two most common and industry important rubbers, natural rubber and styrene-butadiene rubber. A series of ...
Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
(Springer, New York, 2007)
The nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra ...
