Solubility origin at the nanoscale: enthalpic and entropic contributions in polar and nonpolar environments
(Royal Soc Chemistry, 2017)
Nanostructures are known to be poorly soluble, irrespective of their elemental composition, shape, electronic structure, dipole moment, hydrophobicity/hydrophilicity and the employed solvent. The methods of colloid chemistry ...
Estudio del efecto de un solvente iónico sobre las fibras de quitina
(Universidad Michoacana de San Nicolás de Hidalgo, 2018-08)
The proposal of this project is to carry out a comparative study of the effect of an ionic solvent based on NaOH / Urea on chitin fibers. The process of dissolution of chitin is highly important because its poor solubility ...
Development of albendazole sulfoxide-loaded Eudragit microparticles: A potential strategy to improve the drug bioavailability
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Albendazole sulfoxide (ABZSO), a broad spectrum anthelmintic drug extensively used in veterinary medicine, exhibits a low and erratic bioavailability due to its poor solubility in biological fluids. The aims of this study ...
Thermodynamic model of liquid-liquid phase equilibrium in solutions of alkanethiol-coated nanoparticles
(American Chemical Society, 2010-03-03)
A thermodynamic model for a mixture of alkanethiol-coated nanoparticles (NPs) and low-molecular-weight (nonpolymeric) solvent is developed, and calculations of liquid−liquid phase equilibria for different values of NP core ...
DES-mediated approaches toward green analytical chemistry
(Wiley VCH Verlag, 2019)
Over the last few years, environment protection and human health and safety have gained considerable attention in the field of analytical chemistry. In this sense, green analytical chemistry (GAC) have emerged, bringing ...
Solvent effect on the sensitized photooxygenation of cyclic and acyclic alpha-diimines
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-11-13)
The reaction of singlet molecular oxygen with a series of cyclic and acyclic alpha-diimines was studied. Time-resolved methods were used to measure total reaction rate constants and steady-state methods were used to determine ...
