Microwave extraction combined ultrasonic pretreatment of flavonoids from Periploca forrestii Schltr. was investigated in this study, extraction process was first performed in an ultrasonic cleaner, then treated by microwave irradiation. The optimum ultrasonic time of 25 min was selected by single‐factor experiments. A response surface methodology has been used to obtain a mathematical model that describes...
Although the existing theories have predicted enhancement of electrophoretic mobility of microparticles near a solid wall, the relevant experimental studies are rare. This is mainly due to difficulties in experimentally controlling and measuring particle‐wall separations under dynamic electrophoretic conditions. This paper reports an experimental verification of the enhancement of electrophoretic...
