Electrical characterization of radio frequency discharges Article (PDF Available) in Plasma Sources Science and Technology 14(2):S60 May with Reads How we measure 'reads'. Partial electrical discharges in a water solution as a function of conductivity have been studied experimentally. Using needle-plate electrodes it has been demonstrated that the discharge evolves in two phases. During the first streamer-like phase, the discharge propagated with a velocity of 10 6 cm/s, while during the second arc-like phase the length of the discharge remained almost Cited by: Ozone (/ ˈ oʊ z oʊ n /), or trioxygen, is an inorganic molecule with the chemical formula O is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 ().Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Chemical formula: O₃. This book presents the application of pulsed electrical discharges in water and water dispersions of metal nanoparticles in medicine (surgery, dentistry, and oncology), biology and ecology. The intensive electrical and shock waves represent a novel technique to destroy viruses and this way to .
Electric discharge machining is a method of machining in which, as shown in Figure 1, when an electrode and a workpiece are brought closer to each other with pulse voltage being applied between them, dielectric breakdown occurring at a certain distance between them triggers discharge, whose high temperature and pressure in turn cause part of the workpiece to be melted and blown.

KADLEC ET AL.: APPLICATION OF PULSED ELECTRIC FIELD ON BACTERIA The high voltage sourcecan provide quasi-rectangular shape of pulse up to 60 kV of amplitude, 2 µs FWHM and 50 Hz repetition rate. The high voltage source was designed to work to matched load of . The action of electrical discharges and rapidly oscillating current of very high potential on bacteria was investigated in the th (Anderson & Finkelstein, ). The bacteria were suspended in distilled water contained in the test by:
The study was aimed at improvement of recovery of intracellular valuable compounds from olive kernels (Olea europaea). High voltage electrical discharges (HVED), pulsed electric field (PEF), and ultrasound (US) were applied as pretreatments before extraction. The influence of HVED energy input (0– kJ/kg), pH (–12), and ethanol (0–50 %) on the efficiency of the extraction was Cited by: Abstract: A device has been built and tested, in which a ceramic superconducting cathode and a copper anode cause electrical discharges in low pressure gases, at temperatures between 50 and 70 K. The electrodes are connected to a capacitors array charged up to kV; peak currents are of the order of 10^4 A. The cathode has the diameter of 10 cm and is fabricated by OCMTG : Evgeny Podkletnov, Giovanni Modanese. Page 5 - We may take — at random, if you choose — any of the many experiments which may be performed with alternating currents ; a few of which only, and by no means the most striking, form the subject of this evening's demonstration: they are all equally interesting, equally inciting to thought. Here is a simple glass tube from which the air has been partially exhausted/5(4). In such case, in varying the strength and frequency of the currents through the primary, we may observe five distinct forms of discharge, which I have described in my former paper on the subject before the American Institute of Electrical Engineers, [Experiments With Alternate Currents of Very High Frequency and Their Application.
