Solution Thermodynamics of 6-Methylcoumarin in Aqueous Media at Several pH Values
(Colegio Farmaceuticos Provincia de Buenos Aires, 2013-04)
Based on van’t Hoff and Gibbs equations, thermodynamic functions Gibbs energy, enthalpy, and entropy of solution and mixing of 6-methylcoumarin in water at pH 1.2, 6.8, and 7.4, were evaluated from solubility values ...
New method for the simultaneous determination of diffusion and adsorption of dyes in silica hydrogels
(Elsevier Inc, 2014-03)
The fine tuning of porosity in sol gel based devices makes possible the design of novel applications in which the transport of molecules through the oxide gel plays a crucial role. In this work we develop a new method for ...
Stability of furosemide polymorphs and the effects of complex formation with β-cyclodextrin and maltodextrin
(Elsevier, 2016-11)
The effect of the formation of supramolecular binary complexes with β-cyclodextrin and maltodextrin on the chemical and physical stability of the polymorphs I and II of furosemide was evaluated in solid state. The solid ...
Structural aspects of the Co/ZrO2 catalytic system: Effect of the chemical synthesis
(Elsevier Science Sa, 2005-08)
In this work, the application of the Co/ZrO2 catalytic system was studied as catalyst for the reaction of selective reduction of nitrogen oxides with propane in oxygen presence. Particularly, the influence of the preparation ...
Cobalt Supported on Zirconia. Selective Catalytic Reduction of NO Using Propane as Reducing Agent.
(Betham Science, 2014-11)
The catalytic behavior of a series of cobalt catalysts supported on zirconia in the selective catalytic reduction(SCR) of NO has been studied using propane as reducing agent. The catalysts were characterized by Raman ...
Synthesis of ordered mesoporous SBA-3 materials using silica gel as silica source
