A mathematical model of an acoustoelectric transducer based on the use electrokinetic phenomenon flow potential is proposed. It shown theoretically that increases in proportion to strength constant electric pumping field, which confirmed experimentally. The described converter has variable sensitivity. Rather large values sensitivity microphone have been obtained results work can be used design...

In this study, we described a high-sensitive on-line preconcentration method for cypromazine (CYP) and melamine (MEL) analysis using cation-selective exhaustive injection (CSEI) combined with sweeping-MEKC. The optimum conditions of on-line concentration and separation were discussed. The BGE contained 100 mM SDS, 50 mM phosphoric acid (pH=2.0) and 15% acetonitrile (v/v). The sample was injecte...

Nicotine is a potent chemical that excites the central nervous system and refreshes people. It is also physically addictive and causes dependence. To reduce the harm of tobacco products for smokers, a law was introduced that requires tobacco product containers to be marked with the amount of nicotine as well as tar. In this paper, an online stacking capillary electrophoresis (CE) method with ca...

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

The electrokinetic phenomena is also used for decontamination and enhancement of soil–chemical interaction, apart from electro-osmotic consolidation of dewatering. In this paper, an attempt is made to decontaminate the Na contaminated clay using electro-kinetic principle for varying voltage, spacing and number of electrodes. Box type electrokinetic cell was used for this purpose. Results indica...
