When mounted just above a pad of electrically conductive foam and energized with thousands of volts, the needle produces a powerful electric field that ionizes the surrounding air, says University of Washington team member Nels E.
Pulsed electric field (PEF) pasteurization destroys contaminating bacteria with short bursts--less than 1 second--of high voltage.
A dynamic electrical stress (an AC voltage) is applied to the system and dielectric constant and loss tangent or loss factor (product of dielectric constant and loss tangent) are measured as functions of cure time, cure temperature and also as functions of frequency of the applied electric field.
Electric fields are produced by the presence of voltage and are likely to be of substantial magnitude in the workplace only where unshielded high voltage equipment is nearby.
Direct Piezoelectric Effect: When a force is applied to a piezoelectric material, surface charges are induced by the dielectric displacement, and therefore an electric field is built up.
The researchers' theory about dust devils generating peroxide, Delory notes, could be verified by future Mars rovers or landers if they're equipped with an electric field sensor and can analyze Mars' atmospheric chemistry.
An electric field is applied to the particles before they strike the Si detectors so that the protons have enough energy to be detected.
