Aggregation of Disperse Dye in Ethanol-Water Mixtures

Electrospray Onset Study of Water-Ethanol Mixtures

The electrospray ionization (ESI) method is widely used in the analysis of biological molecules. The stable cone regime spray is usually obtained by the addition to the electrosprayed dipolar fluid of methanol or ethanol with the role of reducing the fluid surface tension. We investigate the spray onset voltages of water-ethanol mixtures of various concentrations starting from distilled water t...

solubility of atenolol in ethanol + water mixtures at different temperatures

Preferential Solvation of Fenofibrate in (Ethanol or Acetone) + Water Mixtures at 298.15 K

The aim of this communication was to expand the results of numerical analyses performed by Sun et al. on their experimental solubility of fenofibrate in aqueous mixtures of ethanol and acetone at 298.15 K, in terms of the evaluation of the preferential solvation of this compound by the organic solvents and water in the saturated mixtures based on the inverse Kirkwood-Buff integrals (IKBI). ...

Solubility of the Proteinogenic α-Amino Acids in Water, Ethanol, and Ethanol–Water Mixtures

The addition of organic solvents to α-amino acids in aqueous solution could be an effective method in crystallization. We reviewed the available data on the solubility of α-amino acids in water, water-ethanol mixtures, and ethanol at 298.15 K and 0.1 MPa. The solubility of l-alanine, l-proline, l-arginine, l-cysteine, and l-lysine in water and ethanol mixtures and the solubility of l-alanine, l...

Denaturation and aggregation of lysozyme in water-ethanol solution.

We have applied rheological methods for the analysis of ethanol-lysozyme interaction during the process of denaturation and aggregation of the protein. At low concentration of ethanol a destruction of the hydration shell of lysozyme is observed. With the increase in the ethanol concentration a structural transformation takes place. It leads to the formation of a protein aggregate with an elonga...
