Electrochemical properties of various rock-shaped-CuO/graphite (G) composites and monoclinic structure CuO nanoparticles as the cathode versus a zinc plate as the anode in a 4M NaOH electrolyte were elucidated by electrochemical impedance spectroscopy (EIS) and chronopotentiometry (CP) in a two electrode configuration cell. Various values of G 9, 16 and 28 wt% were prepared and studied as catho...

The conventional methods of drying Chinese wolfberry fruits cause loss of active ingredients and the drying time is very long. In order to explore and investigate the new method of drying Chinese wolfberry fruits, electrohydrodynamic (EHD) drying system was used to drying for Chinese wolfberry fruits with a multiple needle-to-plate electrode on five levels alternating voltage at 0, 20, 24, 28 a...

This article presents the results of comparative studies on streamer propagation and breakdown in a point-insulating plate electrode system in mineral oil and two ester liquids. The studies were performed for a 10-mm gap and a positive standard lightning impulse. The work was focused on the comparison of light waveforms registered using the photomultiplier technique. The results indicated that ...

Detecting the bio-potential changes of plants would be useful for monitoring their growth and health in the field. A sensitive plant monitoring system with flexible boron-doped diamond (BDD) electrodes prepared from BDD powder and resin (Nafion or Vylon-KE1830) was investigated. The properties of the electrodes were compared with those of small BDD plate-type electrodes by monitoring the bioele...

An analytical Mason equivalent circuit is derived for a circular, clamped plate piezoelectric micro-machined ultrasonic transducer (pMUT) design in 31 mode considering an arbitrary electrode configuration at any axisymmetric vibration mode. The explicit definition of lumped parameters based entirely on geometry, material properties and defined constants enables straightforward and wide ranging ...

The electrostatic atomization effect of liquid in high voltage field was studied under capillary-flat electrodes. effects charging voltage, flow rate, and the distance between a capillary flat electrode on droplet size distribution were analyzed by DP-02 laser particle analyzer. single-factor method used to analyze effects. experimental results show that plate greatly influence droplet's effect...

Diverse configurations of needle-type electrodes are commonly used to generate DC or AC corona discharges in various industrial applications. Previous studies confirm that the amount charges generated by discharge is controlled several factors such as level applied voltage, ambient conditions, well geometry electrode system. This paper aimed evaluate distribution uniformity multiple-row and dep...
