Electrospinning technique is currently one of the most important methods for preparing nanofiber. It is important and essential to analyze the distribution of electric field in electrospinning machine. The electric field’s distribution in the typical electrospinning device was calculated and analyzed based on finite element calculation theory of electric field. The electric field is optimized b...

Carotid body chemoreceptors are complex secondary receptors. There are chemical and electric connections between glomus cells (GC/GC) and between glomus cells and carotid nerve endings (GC/NE). Chemical secretion of glomus cells is accompanied by GC/GC uncoupling. Chemical GC/NE transmission is facilitated by concomitant electric coupling. Chronic hypoxia reduces GC/GC coupling but increases G/...

A South American gymnotid, Eigenmannia, is known to be a kind of weak electric fish, producing continuously the electric organ discharge with an intensity of about 1 V. and a constant frequency of about 300 cyc./sec. at 25 C. (Coates, Altamirano & Grundfest, 1954; Lissmann, 1958). The frequency is a function of temperature, with a Q10 of about 1*5. At a fixed temperature, however, the discharge...

Polymer-based capacitors with high energy density have attracted significant attention in recent years due to their wide range of potential applications in electronic devices. However, the obtained high energy density is predominantly dependent on high applied electric field, e.g., 400-600 kV mm-1, which may bring more challenges relating to the failure probability. Here, a simple two-step meth...

The microbicidal effect of electrical discharges on microorganisms suspended in the discharge liquid was reduced when the liquid contained high concentrations of inorganic salts (conductivity k >/= 5 mmho/cm). A higher discharge voltage and a smaller distance between the submerged electrodes counteracted this reduction. The decrease in the microbicidal effect was accompanied by a change in the ...

Electric communication has evolved in certain fishes for the purpose of identification, for forming or maintaining social relationships, and for synchronizing behavior. Relatively little is known regarding this communication channel. Among several distantly related groups of fishes, electric signals originate in specialized electric organs, are transmitted as electric currents in water, and are...
