Ionic equilibrium of 22 hydroxyxanthenes, including halogen and nitro derivatives of
fluorescein, and their thio-and aza analogues, were studied spectrophotometrically in …

The effect of a water-miscible room-temperature ionic liquid (IL), 1-butyl-3-
methylimidazolium tetrafluoroborate ([bmim][BF4]), on the behavior of a common and …

Acrylamide is a toxic species for human health, and is a Maillard reaction product which
forms spontaneously in heat treatment process of foods. Therefore, a simple, fast and cost …

The protolytic equilibrium of fluorescein in aqueous solutions was studied in the presence of
cycloheptaamylose (β-cyclodextrin, or β-CD). The constants of stepwise ionization of the dye …

The stepwise ionization (H3R+⇄ H2R⇄ HR−⇄ R2−) of four fluorescein fluoro derivatives
was studied by visible spectroscopy. The p K a values were determined in water, in 50 …

A negatively charged dye, 8-hydroxypyene-1, 3, 6-sulfonic acid trisodium salt (HPTS), was
successfully incorporated into a silica matrix by using a positively charged polyelectrolyte …

Polymer–fluid interfaces are used widely in a variety of applications, including separations,
which require exposure of the polymer to dynamic flow conditions. Despite the ubiquity of …

We evaluated the relative thermodynamic stability of various molecular and anionic
tautomers of fluorescein, its 2, 4, 5, 7-tetrabromo derivative (eosin), and also …

Determination of factors influencing the efficiency of conjugation of various molecules with
colloidal semiconductor quantum dots (QDs) is an important step toward their biomedical …

The combination of soft-and hard-modeling was used to the spectrophotometric studies of
the acidity constants of 2-(2-Thiazolylazo)-Cresol (TAC) at 25° C and at ionic strength 0.1 …
