[Method] The pomegranate peel polyphe- nol nanoemulsion was prepared by the titration methods and the pseudo ternary dia- gram. The effect of various elements on the formation of the nanoemulsion was stud- ied. [Results] The optimal prescription of the pomegranate peel polyphenol nanoemul- sion was 4.4%(w/w) of pomegranate peel polyphenol, 34.1%(w/w) of EL-40, 17.1%(w/w) of anhydrous ethanol, 5.7%(w/w) of IPM and 38.7%(w/w) of distilled water. [Conclusion] It is feasible to produce the pomegranate peel polyphenol nanoemulsion by the titration methods and the pseudo ternary diagram. It consists of pomegranate peel polyphe- nol, EL-40, anhydrous ethanol, IPM and distilled water. There is 4.4%(w/w) of the pomegranate peel polyphenol in the nanoemuJsion.展开更多

To describe the kinetics of the system, Glauber- type stochastic dynamics has been utilized. The mean-field dynamic equations of the model are obtained from the Master equation. Firstly, these dynamic equations are solved to find the phases in the system. Then, the dynamic phase transition temperatures are obtained by investigating the thermal behavior of dynamic sublattice magnetizations. Moreover, from this investigation, the nature of the phase transitions (first- or second-order) is characterized. Finally, the dynamic phase diagrams are plotted in five different planes. It is found that the dynamic phase diagrams contain the paramagnetic (P), antiferromagnetic (AF5/2, AF3/2, AF1/2) phases and five different mixed phases. The phase diagrams also display many dynamic critical points, such as tricritical point, triple point, quadruple point, double critical end point and separating point.展开更多
The electrochemical behavior of ionizable drugs (Amitriptyline, Diphenhydramine and Trihexyphene- dyl) at the water/1,2-dichloroethane interface with the phase volume ratio (r = Vo/Vw) equal to 1 are investigated by c...The electrochemical behavior of ionizable drugs (Amitriptyline, Diphenhydramine and Trihexyphene- dyl) at the water/1,2-dichloroethane interface with the phase volume ratio (r = Vo/Vw) equal to 1 are investigated by cyclic voltammetry. The system is composed of an aqueous droplet supported at an Ag/AgCl disk electrode and it was covered with an organic solution. In this manner, a conventional three-electrode potentiostat can be used to study the ionizable drugs transfer process at a liquid/liquid interface. Physicochemical parameters such as the formal transfer potential, the Gibbs energy of transfer and the standard partition coefficients of the ionized forms of these drugs can be evaluated from cyclic voltammograms obtained. The obtained results have been summarized in ionic partition diagrams, which are a useful tool for predicting and interpreting the transfer mechanisms of ionizable drugs at the liquid/liquid interfaces and biological membranes.展开更多
