Kinetics of the neutral hydrolysis of 4-nitrophenyl chloroacetate was investigated in water and in the presence of 1 mol % of ethanol, propanol, and -butyl n alcohol without sonication and under ultrasound at 25 kHz. Similarly, the kinetics of the acid-catalysed hydrolysis of -propyl n acetate in ethanol–water binary solutions was investigated without sonication and under ultrasound at 22 kHz. ...

This work demonstrates the fabrication of surface-textured microcapsules formed from emulsion droplets, which are stabilized by an interlocking mesh needle-like crystals. Crystals small-organic-compound decane-1,10-bis(cyclohexyl carbamate) within geometric confinement through precipitation a binary-solvent-dispersed phase. binary mixture consists volatile solvent and nonvolatile carrier oil. C...

In the study, I investigated microphaseseparated nanostructures of PS-P2VP thin films by annealing in binary solvent vapors of chloroform and methanol. Ordered microphase-separated nanostructures were achieved by controlling solvent annealing conditions. One of the key parameters is the compositions of binary co-solvent vapors. We also discuss the thermodynamic properties of perpendicularly-or...

Calixresorcinarenes have proved to be unique molecules for molecular recognition via hydrogen bonding, hydrophobic and ionic interactions with suitable substrates such as cations. The study of the interactions involved in the complexation of different cations with calixresorcinarenes in solvent mixtures is important for a better understanding of the mechanism of biological transport, molecular ...

Anion recognition of two flexible diols in different solvents and binary mixtures were examined. Binding constants (K) in CD3CN and CDCl3 are surprisingly similar, and CD3CN-solvent mixtures led to reduced values of K that are smaller than in either pure solvent. A surprising U-shaped dependence is observed.
