Host-guest interactions are an attractive approach to design redox electrolytes, enabling precisely tune the key properties for flow batteries such as half-cell potential, solubility, and stability. Herein we report a host-guest complex of highly water soluble (2-hydroxypropyl)-β-cyclodextrin with 1-decyl-1′-ethyl-4,4′-bipyridinium dibromide anolyte in new aqueous organic battery (AORFB). The s...

The supramolecular structure of the inclusion complex of β-cyclodextrin (β-CD) with 1,1',2,2'-tetramethyl-3,3'-(p-phenylenedimethylene) diimidazolium dibromide (TetraPhimBr), a dicationic ionic liquid, has been investigated. The inclusion complex with 1:1 molar ratio was prepared by a kneading method. Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD) analysis, (1)H ...

Vinpocetine is a poorly water soluble drug, commonly used in treatment of various cerebral insufficiency conditions. The aim of this work was to formulate vinpocetine in the form of orally disintegrating tablets (ODTs) and enhance its solubility and dissolution rate. This objective was addressed using lyophilization technique of either solid dispersion using polyethylene glycol 4000 (PEG 4000) ...

Forming complexes with cyclodextrins can enhance the dissolution rate, the stability, the solubility and the bioavailability of a drug. In this work, piroxicam/β-cyclodextrin complexes were prepared at solid state by means of supercritical carbon dioxide. The influence of temperature, residence time, water content and a ternary agent, L-lysine, were studied. The complex was characterized by Dif...

Here, we demonstrated the electrospinning of polymer-free nanofibrous webs from inclusion complex (IC) between hydroxypropyl-β-cyclodextrin (HPβCD) and Vitamin E (Vitamin E/HPβCD-IC NF). The inclusion complexation between HPβCD and Vitamin E was prepared by using two different molar ratios (Vitamin E/HPβCD; 1:2 and 1:1), which correspond to theoretical value of ∼13% (w/w) and 26% (w/w) loading ...
