Abstract:

An analysis of the physical and chemical phenomena accompanying electrical discharges is carried out, and the main factors influencing microorganisms’ abatement are studied. The similarity of the cavitation processes in water systems induced by underwater electric discharges and ultrasound is experimentally demonstrated. The characteristic features of electrical discharge in the cavitation mode, providing effective water disinfection with electric discharges with a significantly reduced amount of active chlorine, are identified in order of importance.

The article deals with the study of factors participating in the extraction of humic acids from plant substrates under the action of electric discharges. Using the example of the electric discharge treat-ment of the peat-water suspension, it was demonstrated that the main factor affecting the intensity of extraction is the degree of the solid phase of the biosubstrate-water suspension grinding, which depends on the pressure amplitude at a distance of the inner radius of the chamber and the number of discharge pulses.

Numerous studies have been conducted on spent lithium-ion batteries (LIBs) recycled from electric vehicles. Research on pre-processing techniques to safely disassemble spent LIB packs has mainly focused on water-based discharge methods, such as salt-water discharge. However, salt-water discharge corrodes the electrodes and case, causing internal contamination. Therefore, we propose an electrical discharge process that is suitable for the direct recycling and safe disassembly of spent Li-ion batteries.

How do the communication discharges produced by electric fish evolve to accommodate the unique design features for the modality?

Electrostatic theory predicts that electric discharges from fish will have a short range because of the inverse cube law of geometric spreading around an electrostatic dipo

A two-dimensional model was developed to calculate the electrostatic field in the DBD discharge chamber (DC), which includes two electrodes, a dielectric barrier, two water droplets or streams in the air gap, and water films.

After houseflies were dehydrated, rehydrated, refrigerated, and frozen and thawed, they were placed in static and dynamic electric fields.

Abstract:

In this paper, a pin-to-plate reactor with a water droplet as a suspended electrode is employed to investigate the dynamic evolution of pulsed air discharge over the water droplet. The temporal and spatial evolution of the pulsed discharge is captured by an intensified charge-coupled device (ICCD) camera, and the spatial distribution of the electric field is obtained by solving the Maxwell equations. Our ICCD measurements show that the discharge is initiated in the gas gap between the anode and the droplet, and then it propagates over the droplet. Our simulation confirms that the strong electr

Abstract:

With the accelerating construction of strong smart grid, and the grid voltage level rising, performance requirements for the electrical insulation of electrical equipment also continue to increase. In terms of the advantages of RTV on antifouling, RTV-based paints coated insulator coating capacity of its flash tolerance can significantly increase, mainly due to RTV coating hydrophobic hydrophobicity and migration. But when the hydrophobic surface is in the fully wet, many small drops of water in the surface will be gathered into big drops of water, and these large droplets will distort the sur

ABSTRACT This study aimed to characterize the bacterium-destroying properties of a gliding arc plasma device during electric discharges and also under temporal postdischarge conditions (i.e., when the discharge was switched off). This phenomenon was reported for the first time in the literature in the case of the plasma destruction of microorganisms. When cells of a model bacterium, Hafnia alvei, were exposed to electric discharges, followed or not followed by temporal postdischarges, the survival curves exhibited a shoulder and then log-linear decay. These destruction kinetics were modeled us

Abstract Analogy can be considered as an approach in teaching an abstract concept, where in electricity related to capacitor, water and containers are sometimes used. In this work we try to summerize available reports related to this. Usually, the water flow (WF) represents electric current, water height (WH) is an analogy to electric potential difference, container floor area (FA) can be viewed as capacitance, hose (HS) is as connecting wire, and water reservoir with large floor area (WR) behaves as a battery.

Recently, ingots of silicon carbide have been adapted to be sliced by the wire-cut electrical discharge machining. Fast slicing, and the reduction in the loss are important for slicing of the wafer. In this paper, characteristic features of the electric discharge machining in the ion-exchange water and the fluorine-based fluid were compared for these improvement. The discharge was caused by a pulse voltage applied to a ingot of silicon carbide and the wire in machining fluid, and the slicing was proceeded. As a result, improvement of surface roughness and kerf loss was confirmed, for the first

Polycrystalline diamond (PCD) has been used widely in modern industry. However, the manufacture of PCD blanks is not an economical and efficient process. The shaping of PCD blanks with conventional machining methods (such as grinding), is a long, labour-intensive and costly process. Electromachining processes promise to be effective and economical techniques for the production of tools and parts from PCD blanks. Wire electric discharge machining is able to effectively slice PCD. Electrical discharge machining (EDM) and electrical discharge grinding (EDG) shape PCD blanks at a lower cost. Howev
