Experimental collisional energy transfer data from kinetically controlled selective ionization (KCSI) and ultraviolet absorption (UVA) experiments are analyzed in the framework of the partially ergodic collision theory (PECT). Collisions of azulene and biphenylene with different colliders are investigated as case studies. The downward wings of the P(E',E) energy transfer distributions obtained ...

Zinc oxide is one of the most popular materials for acoustoelectronic sensors and vibro-piezo-transducers used in nano-piezo-generators. In present paper, thick piezoelectric ZnO films are fabricated on both sides various substrates using magnetron sputtering technique. It shown that main problem double film deposition difference thermal expansion coefficients substrate materials. The solved by...

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 purpose of this study was to evaluate the efficiency of intracytoplasmic sperm injection (ICSI) and Piezo-assisted sperm injection after pretreatment with calcium ionophore (CaI) on the mouse embryo development. Methods: In this study, the conventional ICSI and Piezo-ICSI procedures were used. The efficacy of the methods was examined after mouse matured oocytes were fertilized with or witho...

This paper is a thorough review of innovative architectures electro-hydraulic servovalves that exploit actuation systems based on piezo-electric materials. The use commercially available actuators, namely, piezo stacks, amplified rectangular benders, and ring very promising for the main stages pilot given fast response low weight piezoelectric these actuators can also allow novel designs to be ...
