In the present study by applying electron spin resonance-spin trapping method, when a high frequency (1650 kHz) ultrasound was irradiated to water dissolved with different gas molecules (O(2), N(2), Ar, Ne, He, and H(2)) at 25°C of water bulk temperature, free radical generation pattern differed dependently on the dissolved gas molecules. Only (•)OH was detected in the O(2)-dissolved water samp...

Contrast enhancement by microbubble infusion has proven its applicability in the field of diagnostic ultrasound. Recent studies also indicate a therapeutic effect of the combined use of ultrasound and microbubbles. Results from animal studies demonstrate that diagnostic ultrasound in combination with intravenous microbubbles can dissolve thrombi. So far, this effect has never been tested in pat...

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for de...

Ultrasonic breakdown of perfluorooctanoic acid and perfluorooctane sulfonic were evaluated at various ultrasonic frequency (575 kHz, 860 1140 kHz), pH (3–12), bulk water temperature (14.5–30 °C), gases (Helium, Nitrogen, Oxygen, Ozone, Argon). Contrary to the result reported in literature, we observed an increase rate kinetics PFOA PFOS decomposition air environment (i.e., without sparging any ...
