Sonication-assisted nonpolar-antisolvent approach to produce cellulose suspensions, disaggregated by a nonpolar-antisolvent with orthogonal Kamlet-Taft acidity/basicity: Roles of net-basicity and cosolvency [PDF]

open access: yesUltrasonics Sonochemistry
This work reports a simple sonication-assisted approach to produce diluted (0.5 mg/mL) suspensions of cellulose in the non-functionalizing nonpolar-antisolvent tetrahydrofuran (THF), which has a purely basic character (null Kamlet-Taft acidity parameter,

Review of the cosolvency models for predicting solubility of drugs in water-cosolvent mixtures

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2008
The cosolvency models presented from 1960 to 2007 were reviewed and their accuracies for correlating and/or predicting the solubility of drugs in water-cosolvent mixtures were discussed.

Deep Eutectic Solvents as Agents for Improving the Solubility of Edaravone: Experimental and Theoretical Considerations [PDF]

open access: yesMolecules
In this study, both practical and theoretical aspects of the solubility of edaravone (EDA) in Deep Eutectic Solvents (DESs) were considered. The solubility of edaravone in some media, including water, can be limited, which creates the need for new ...

Determinação do coeficiente de distribuição (Kd) de benzo(a)pireno em solo por isotermas de sorção Determination of the distribution coefficient (kd) of benzo(a)pyrene in soil using sorption isotherms [PDF]

open access: yesQuímica Nova, 2006
Leaking of diesel oil from gas stations is frequent in Brazil. The presence of polycyclic aromatic hydrocarbons (PAHs), which are highly toxic is an indication of contamination by heavy hydrocarbons from diesel oil. Here were present the determination of
