Competitive Cd2+/H+ complexation to polyacrylic acid described by the stepwise and intrinsic stability constants
(American Chemical Society, 2008)Stepwise constants can be used to describe competitive proton and metal binding to macromolecules with a large number of sites. With the aim of accessing information on the microscopic binding model, we report an expression ... -
Dealing with long‐range interactions in the determination of polyelectrolyte ionization properties. Extension of the transfer matrix formalism to the full range of ionic strengths
(Wiley, 2016-11-14)The ionization state of charged macromolecules in solution is usually determined by the extent of the binding processes. These processes are very sensitive to the ionic strength of the medium, which are of long-range nature. ... -
Effect of novel deep eutectic solvents on the endo/exo ratio of diels–alder reactions at room temperature
(American Chemical Society, 2021)The Diels–Alder reaction is a prototypical example of a thermally allowed [4 + 2] cycloaddition with good control over the regio- and stereochemical outcomes. Therefore, Diels–Alder reactions in which adjacent stereocenters ... -
Is it possible to substitute hexane with green solvents for extraction of carotenoids? A theoretical versus experimental solubility study
(Royal Society of Chemistry, 2016)The present study was designed to evaluate five green solvents, i.e. 2-methyltetrahydrofuran (2-MeTHF), dimethyl carbonate (DMC), cyclopentyl methyl ether (CPME), isopropyl alcohol (IPA) and ethyl acetate, for the substitution ... -
Systematic Investigation of the Physicochemical Factors That Contribute to the Toxicity of ZnO Nanoparticles
(American Chemical Society, 2014)ZnO nanoparticles (NPs) are prone to dissolution, and uncertainty remains whether biological/cellular responses to ZnO NPs are solely due to the release of Zn2+ or whether the NPs themselves have additional toxic effects. ...
