    To investigate the sonochemical reaction performance caused by the indirect irradiation at 500 kHz, the glass vessel and a KI aqueous solution were used. Both the ultrasonic power and reaction rate had maximum values at every half wavelength of ultrasound. When the vessel position was adjusted to a larger absolute value of transducer impedance, the reaction rate became higher. The reaction rate and ultrasonic power increased as the vessel position moved closer to the transducer. The reaction rate first increased as the electric power applied to the transducer increased, reached a maximum value, and then decreased. This decrease phenomenon is called quenching of the sonochemical reaction. Before the quenching occurrs, the reaction rate per unit volume almost linearly increased with ultrasonic power density. The effects of the vessel diameter and liquid height on the relationship between the reaction rate per unit volume and the ultrasonic power density were small.

  5. Evaluation of solvent property of air-water interface based on the fluorescence spectra of 1,2′-dinaphthylamine in the aqueous solution of ultrafine bubbles Reviewed Open Access

    Solvent property of air–water interface was evaluated based on the fluorescence spectra of 1,2′-dinaphthylamine in water containing ultrafine bubbles (average diameter: 103 nm, standard deviation: 38 nm). Among naphthylamine derivatives whose fluorescence spectra were responsive to microscopic hydrophobicity, 1,2′-dinaphthylamine (DN) was selected because its wavelength of the maximum emission (λmax) was significantly dependent on the concentration and microenvironment of the ultrafine bubble. The λmax value of DN in water was 486 nm, while it shifted to shorter wavelength (408 nm) in the presence of 1.09 × 109 mL−1 of ultrafine bubbles. The shift of λmax value indicates that DN adsorbs on the surfaces of ultrafine bubbles and exists in hydrophobic region rather than in bulk water. By comparing with the λmax values in different solvents, the surface of ultrafine bubble was found to have similar solvent property to ethyl ether or ethyl acetate that are widely used as extracting solvents for hydrophobic organic compounds.

    Alcohol-modified air bubble flotation was designed as a simple, efficient, and eco-friendly method for the rapid separation of dyes and pharmaceuticals. The method was conducted by adding a small amount of alcohol to water in a cylindrical glass vessel with a sintered glass filter at the bottom followed by feeding air to generate air bubbles. Basic dyes and pharmaceuticals in water were enriched to temporarily generated foam on the surface of water and therefore removed from water. The separation efficiency increased with increasing alcohol concentration and carbon number in the order: ethanol < 2-propanol < 1-butanol), being attributed to the decrease in the size of air bubble, which in turn increases the surface area of air-water interface for the adsorption of the dyes. Hydrophobic interactions are a predominant factor for the adsorption on the air-water interface. The applicability was successfully demonstrated by using environmental water and synthesized dyeing wastewater.

    High-purity metal nanoparticles without capping agent were synthesized by ultrasonic method. We succeeded to control the diameter of gold nanoparticles by changing the addition concentration of ultrafine bubbles (UFB), which are fine bubbles with a diameter of less than 1 micrometer, during the synthesis. Furthermore, the precipitation of gold and palladium nanoparticles was suppressed by adding UFB to the nanoparticle colloids after synthesis.
    A protein-immobilized electrochemical sensor was fabricated using gold nanoparticles synthesized by ultrasonic method, and was able to detect reactive oxygen species in water.
    Composite particles of palladium or platinum precipitated on the surface of tungsten oxide particles with photocatalytic performance were synthesized by ultrasonic method. The photocatalytic performance of the decolorization reaction was improved by compositing the particles.

    In this study, a novel method was developed to control the responsive temperature of poly(NIPAM-co-HEMA) using an ultrasonic polymerization technique. Initially, the behavior of the reaction was investigated using NIPAM and HEMA monomers under ultrasonic irradiation. Furthermore, the effect of the ultrasonic irradiation conditions on the temperature responsiveness of the copolymer was investigated. The lower critical solution temperature (LCST) of the copolymer was found to increase with increasing ultrasonic irradiation time. In addition, the measured values of the LCST in the early stages of the reaction were higher than the estimated values using copolymer composition. These results are of importance to control of the temperature responsiveness of poly(NIPAM-co-HEMA) using ultrasonic irradiation.
