The present subject matter is directed to water disinfection by pulsed electric field (PEF) systems. The present subject matter relates to a pulsed electric field assembly with a separator that separates and disinfects the microorganisms in drinking water. The present subject matter relates to an anti-corrosion electrode, particularly an electrode having a zeolite coating layer serving as a protector, a process for the preparation a zeolite coating on a conducting electrode substrate, and application of the zeolite coated electrode on water electrolysis and PEF systems.

Pulsed electric field for drinking water disinfection

The present disclosure relates to a micro-mini pulsed electric field (PEF) device for point-of-use disinfection of drinking water. The pulsed electric field device comprises micro-engineered electrodes and a low-voltage pulsed electric field generator circuit. A pulsed electric field is generated across a micro-gap between the electrodes to achieve disinfection of drinking water.

Transdermal patches and devices for delivery of therapeutic drug and/or cosmetic formulations through an intact or porated skin barrier are described. Active-infusion delivers controlled dosing over a period of time to provide long-term efficacy. Methods and devices for preparing active-infusion patches for controlled dose delivery by nonelectronic devices and methods of skin poration that is safe and painless are described.
