Modeling and predictions of solids dynamic holdup in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2004)
A model based on first principles and free of any semiempirical parameters is presented for trickling solids holdup in gas-flowing solids-fixed bed contactors. A small double-cone cavity is used to characterize the voids ...
Osmotic coefficient of the ZnCl2(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2003)
The osmotic coefficient of ZnCl2(aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4) mol . kg(-1) with KCl(aq) as the reference solution. The available literature ...
Solids residence time distribution in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2005)
Flowing solids residence time distribution in gas-flowing solids-fixed bed contactors was investigated using a tracer technique with a step signal as input. Particles of different color (all other properties being the same) ...
Use of nonlinear frequency response for discriminating adsorption kinetics mechanisms resulting with bimodal characteristic functions
(Springer, New York, 2003)
One of the characteristic examples of the inability of the classical linear frequency response (FR) method to identify the correct kinetic mechanism is adsorption of some substances (p-xylene, 2-butane, propane or n-hexane) ...
Cardiac tissue engineering: effects of bioreactor flow environment on tissue constructs
(Wiley, Hoboken, 2006)
The limited ability of cardiac muscle to regenerate after injury and the small number of organs available for transplantation motivate studies aimed at curative treatment options. Tissue engineering based on the integrated ...
A QSAR study of acute toxicity of N-substituted fluoroacetamides to rats
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Acute toxicity in vivo toward rats, of nineteen N-alkyl and N-cycloalkyl fluorocetamides [F-CH2-C(O)-NH-R] was correlated with their structure-dependent properties. Used descriptors are: molecular weights (M-w) and heat ...
Studies on electrochemical oxidation of azithromycin and Hemomycin (R) at gold electrode in neutral electrolyte
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
The aim of the present study was to examine the oxidative properties and an assay of azithromycin and Hemomycin (R) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry. The maximum value of the ...
Nanostructured bioglass thin films synthesized by pulsed laser deposition: CSLM, FTIR investigations and in vitro biotests
(Elsevier, Amsterdam, 2008)
We report the synthesis by pulsed laser deposition of thin structures of two bioactive glasses belonging to the SiO2-Na2O-K2O-CaO-MgO-P2O5 system, on medical grade Ti substrates. We evaluated their biocompatibility after ...
Surface chemistry of CO on Pt(100)-bimetallic surfaces: Displacement effects
(Amer Chemical Soc, Washington, 2000)
The surface chemistry of coadsorbed CO and metal adatoms on the Pt(100) surface in acid electrolyte has been studied by means of rotating ring disk electrode (RRDE) measurements. These results showed that Cu and Pb adatoms ...
Polypyrrole as possible electrode materials for the aqueous-based rechargeable zinc batteries
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
Polypyrrole (PPy) thin film electrode was galvanostatically synthesized and characterized in 0.1 M HCI on graphite electrode as cathode materials for the aqueous-based rechargeable zinc batteries. The charge/discharge ...
