Cyclodextrin (CD)-based [3]rotaxane formed aggregation structures under the appropriate conditions, as was clearly observed for first time. Detailed study of this phenomenon revealed that aggregated with hexagonal packing owing to hydrogen bond formation among CD units, in a manner similar polyrotaxane species. This could be controlled by solvent type upon dispersion, through axle end structure...

We show that the process of irreversible, kinetic colloid aggregation exhibits universal behavior, independent of the detailed chemical nature of the colloidal particles. Modem methods of statistical physics, applied to a kinetic growth process, provide a good basis to model the observed behavior. Two limiting regimes of colloid aggregation are identified: rapid aggregation, limited solely by t...

Systematic studies on the vapor-liquid equilibria (VLE) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([C12mim]Br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...

In this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic Ionic Liquids (ILs), 1 – allyl - 3 - methylimidazolium chloride ([Amim]Cl), 1 - ethyl - 3 - methylimidazolium chloride ([Emim]Cl), 1 - butyl - 3 - methylimidazolium chloride ([Bmim]Cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([Bmim]BF4) were investigated using conductivity and laser ...

Abstract: Objectives: A systematic study is required to enhance the solubility of insoluble fluid drugs that are only sparingly soluble. Hydrotropy may be a distinctive development reinforce liquid poorly water-soluble drugs. Materials and Methods: The term hydrotropic has been wont designate rise in assorted substances water because presence enormous amounts additives. Sodium salicylate, sodiu...
