Synthesis of mullite nanostructured spherical powder by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
In this paper the synthesis of nanostructured spherical particles of mullite powders by ultrasonic spray pyrolysis is presented. The mullite crystallization and the nanostructure development during heating were examined ...
Electrooxidation of H-2, CO, and H-2/CO mixtures on a well-characterized Pt70Mo30 bulk alloy electrode
(Amer Chemical Soc, Washington, 1998)
The electrochemical oxidation of hydrogen (H-2), carbon monoxide (CO), and their mixtures (500 ppm-2%) on a well-characterized Pt70Mo30 bulk alloy was examined using the rotating disk electrode technique in 0.5 M H2SO4 at ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters, 10 - Synthesis and characterization of alpha,omega-dihydroxyoligo(alkylene maleate)s
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees C, of potassium maleate and 1,4-dibromobutane, ...
Technetium-99m labeling of hippuric and p-amino-hippuric acid in the presence of DTPA: Biological and pharmacokinetic evaluation and comparison with Tc-99m-DTPA
(Springer, Dordrecht, 1999)
Tc-99m-Hipp as a modified Tc-99m-DTpA, and Tc-99m-PAH as a new renal agent are developed. Each veal of lyophilised kit contain hippuric (Hipp) or p-aminohippuric acid (PAH), diethyltriaminepentaacetic acid as calciumtrisodium ...
Nonlinear frequency response of adsorption systems: isothermal batch and continuous flow adsorbers
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The problem of nonlinear frequency response of adsorption systems is treated using the concept of higher-order frequency response functions (FRFs). The FRFs on the adsorber and on the particle scale are considered. Based ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - I. A semi-batch adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A semi-batch mode of operation is considered, ...
Frequency response of an adsorber with modulation of the inlet molar flow-rate - II. A continuous flow adsorber
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
A new method of frequency response analysis of an adsorber, with modulation of the adsorbate molar supply instead of traditional modulation of the reservoir volume, is presented. A continuous mode of operation is considered, ...
Simultaneous presentation of VLE, H-E and c(p)(E) by the PRSV equation of state with the modified van der Waals one-fluid and Huron-Vidal-Orbey-Sandler mixing rules
(Elsevier, Amsterdam, 1999)
The Stryjek-Vera modification of the Peng-Robinson equation of state with two parameter van der Waals one-fluid mixing rule suggested by Schwartzentruber and Renon (SR) and the Orbey-Sandler modification of the Huron-Vidal ...
Effect of temperature on surface processes at the Pt(111)-liquid interface: Hydrogen adsorption, oxide formation, and CO oxidation
(Amer Chemical Soc, Washington, 1999)
The variation of the adsorption pseudocapacitance with temperature is used to obtain the enthalpy, entropy, and free energies of adsorption of H-upd and OHad on Pt(lll) as a function of pH and nature of the anion of the ...
Modeling of nanostructural design of ultrafine mullite powder particles obtained by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
In this paper, a model of substructure design of mullite powder particles obtained by spray pyrolysis lit the field of ultrasound excitation is described. Based an this model, the size of subparticles (nanoparticles) ...
