Pruning of Juglans mandshurica produces many branches, which are potentially a rich source juglone although they usually discarded as waste. Herein, we describe water-in-oil microemulsion-based microwave-assisted extraction (MBMAE) method to isolate the found in waste branches from J. mandshurica. In our experiment, branch powder was added MBMAE system. Using optimized microemulsion system comp...

Changing the formulation variables of microemulsion systems has a significant influence on the resulting transdermal enhancement effect. NMR diffusion-ordered spectroscopy (DOSY) can offer an extremely valuable tool to interpret the differences in the obtained fluxes based on variations in self-diffusions between the drug and its locus domain. From the clinical editor: Microemulsion systems are...

the paper is focused on the formation of calcium phosphate nanoparticles (cp) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, anionic surfactantant and cosurfactant, in the presence of anionic and cationic polyelectrolyte. it is shown that polyelectrolyte, can be incorporated into the individual inverse microemulsion droplets. the ...

Yolk-shell TiO2 microspheres were synthesized via a one-pot template-free solvothermal method building on the aldol condensation reaction of acetylacetone. This unique structure shows superior light scattering ability resulting in power conversion efficiency as high as 11%. This work provided a new synthesis system for TiO2 microspheres from solid to hollow and a novel material platform for hig...

Glibenclamide is practically insoluble in water and its gastrointestinal absorption is limited by its dissolution rate. Therefore, to enhance the drug dissolution and its hypoglycemic effects, the drug was formulated in different microemulsion systems and in vitro/in vivo evaluated. Microemulsion systems were prepared by Water titration method in which surfactants and cosurfactants (S/CoS) were...

in this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. the effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

A local ordered structure constructed from solid Cu(2)O nanocubes was obtained by the radiolytic reduction of Cu(NO(3))(2) in a water-in-oil (W/O) microemulsion composed of Triton X-100, n-hexanol, cyclohexane, and water in the presence of ethylene glycol (EG). However, when Triton X-100 was replaced with Brij 56 in the microemulsion, hollow Cu(2)O nanocubes were synthesized. The addition of to...

Multifunctional Bi2O3 porous nanospheres (PNs) with tunable size have been successfully synthesized via a facile solvothermal method. The obtained Bi2O3 porous nanospheres demonstrate outstanding performance in visible-light-driven photocatalysis for Cr(VI) and organic dye removal, inactivation of Gram-negative and Gram-positive bacteria, as well as template-synthesis for fabrication of bismuth...
