Investigation of pulsed electric field (PEF) treatment yeast at 20 kV/cm using chambers with BaTiO3 dielectric layers was conducted in this study. The sterile rate as well concentrations metallic ions and hydroxyl radicals were measured to assess the PEF performance. results indicated that generation could be reduced by 90%. However, a much higher strength would required for satisfactory steril...

In this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. This mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (MAF) process. A permanent magnet which is mounted on a horn has been used as the processing tool. This polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. Ultrasoni...

The NMR spin-spin coupling constants (SSCCs) across the H-bond in proteins are sensitive to the electronic structure of the H-bonded system, i.e., the N-H‚‚‚OdC group in proteins. The spin-spin coupling mechanism across the H-bond involves a strong electric field effect, steric exchange interactions, and some weak covalent effects (transfer of electronic charge). The electric field effect is re...

OBJECTIVES This article describes interaction of the Earth's mass-electrolytic conductor on the electrical environment of human organism-aqueous environment and skeleton. In this environment, bioelectrical and bioenergetical processes take place. METHODS AND SUBJECTS Measurements of electric potential on tongue, teeth, nails, and in venous blood in subjects earthed and unearthed were conducte...

Multi-Walled CNT (MWCNT) are synthesized on a silicon wafer and sputter coated with a gold film. The planar surfaces are mounted on the tip of a piezo-electric actuator and mated with a gold coated hemispherical surface to form an electrical contact. These switching contacts are tested under conditions typical of MEMS relay applications; 4 V, with a static contact force of 1 mN, at a low curren...
