The liquid crystal form with phosphatidylcholine contents containing in the hydrogenated lecithin was confirmed. Composition ingredients of the liquid crystal vesicle were phospholipid, ethanol and water and the rosmarinic acid was encapsulated as index material. The mean particle size of the liquid crystal vesicle appeared to form various particles form 480 nm to 3 μm depending upon the lipid composition and ultrasonic handling time. The liquid crystal vesicle compared with the liposome showed a very high encapsulation efficiency. The quantity of liquid crystal vesicle increased with respect to the increased quantity of lipid contents in the hydrogenated lecithin. The result from release experiments of the liquid crystal vesicle containing rosmarinic acid showed that the liquid crystal vesicle releases much less than that of liposome. Source

Modifying surface of activated carbon for the electrode of EDLC with an organic electrolyte was investigated to improve the electrochemical performance of EDLC by the microwave radiation. Three kinds of activated carbons, prepared activated carbon from petroleum cokes and pitch cokes and commercial activated carbon BP-25, were used for this study. For all investigated activated carbons, hydrophilic functional groups-containing oxygen disappeared from the surface of activated carbon as microwave radiation. And as microwave radiation time was increased, the specific surface area and total pore volume of activated carbons were reduced and average pore diameter were increased. From theses effects, interfacial resistance of EDLC with the modified activated carbon electrode was drastically decreased, and discharge capacitance was increased although the specific surface area of activated carbon was reduced by this microwave radiation.
