Abstract:

This study aims to determine the magnetic properties and structural properties of zinc ferrite (ZnFe2O4) material with the sonochemichal synthesis method. The sonochemichal method was obtained by sonication lasting for 30 minutes with the addition of 100 ml of 10 M NaOH. ZnFe2O4 material was sintered with temperature variations of 950°C, 1050°C, and 1150°C with a holding time of 2 hours. Phase identification revealed that the cubic phase structure of zinc ferrite is franklinite and also obtained crystal size results with values of 70.58 – 84.71 nm.

Silver oxide (Ag2O) nanoparticles have been successfully synthesized through several methods, namely sol-gel, sonochemical, and biological methods. X-ray diffraction studies revealed that the sonochemical method produces silver oxide with high phase purity, then the sol-gel method produces another phase, namely silver crystals, while the biological method produces Ag3PO4 phase from the precursor media. The research showed that the sol-gel method had the smallest crystallite and particle sizes of 9.5 and 232.7 nm, respectively, compared to sonochemical and biological methods. It is known that t

Abstract:

Sonochemistry is considered a green alternative for chemical synthesis, water treatment, and hydrogen production. There are several steps for sonochemical reactions. First, the nucleation of a bubble must occur through the application of an intense acoustic pressure field. After further ultrasonic irradiation, the bubble must grow to a diameter beyond a certain threshold so that it undergoes inertial collapse during the compressional phase of the acoustic field. Finally, this inertial collapse must achieve a quasi-adiabatic compression to cause pyrolysis of the gas or vapour molecules into rad

Abstract:

Sonochemistry involves several steps. First, an acoustic wave must be generated with sufficient energy to nucleate cavitation. This cavitation event must then be energetic enough to produce radicals through the sonolysis of the gas or vapor molecules in the bubble. Finally, these radical species must survive long enough to react with other chemical species to yield the desired product. The sonochemical efficiency (SE) is thus defined as the ratio of the product yield to the input acoustic power. Here, we put forward a novel approach to enhancing the SE by designing a multi-frequency (0.25 to 1

The increasing bacterial resistance and negative impacts of the present antibacterial agents have led to the search for novel antibacterial agents. This study focuses on the influence of synthetic methods on the aggregation stability and antibacterial activity of gold nanoparticles (NPs) prepared by using sodium citrate as a reducing and capping agent against Staphylococcus aureus (S. aureus). Gold NPs were synthesized using a simple and rapid sonochemical method and compared to gold NPs synthesized using a reduction method. The physicochemical features of gold NPs were characterized using UV-

Abstract:

A sonochemical method has been applied to prepared PbWO4 crystals by using different precursors. The as-prepared samples were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). It was found that the precursor played an important role in the synthesis of PbWO4 crystals. PbWO4 nanostructures with different morphologies, such as flower-like, rod-like, and dendrite-like, have been successfully obtained via a mild sonochemical method corresponding to the precursor PbCO3, Pb(NO3)2, and Pb(Ac)2, respectively.

Abstract:

This paper presents the effects of various parameters that significantly affect the cavitation. In this study, three types of liquid mediums with different physicochemical properties were considered as the cavitation medium. The effects of various operating parameters such as temperature, pressure, initial bubble radius, dissolved gas content and so forth, were investigated in detail. The simulation results of cavitation bubble dynamics model showed a very interesting link among these parameters for production of oxidizing species. The formation of •OH radical and H2O2 is considered as the res

Abstract:

This research aimed at sonochemical synthesis and deposition of Fe3O4/ZnO nanocomposites on cotton/polyester fabric using the ultrasonic bath at 80℃. For this purpose, in situ sonosynthesis of magnetite nanoparticles on the fabric surface was carried out and followed by the generation of crystalline ZnO nanoparticles through the sonochemical approach, eliminating the need for high temperature after-treatment of the fabrics. This effect was achieved thanks to the shock waves formed by the cavitation bubbles also called microcalcination, resulting in the formation and adsorption of crystalline n

Abstract:

Ultrasound has shown to improve a spectrum of applications such as crystallization, degradation, synthesis, extraction, and cell disruption. These improvements largely stem from the cavitation induced extreme physical and/or chemical effects. Cavitation activities are often quantified using sonoluminescence intensity or sonochemical yield and are dependent on sonication conditions. For example, frequencies less than 100 kHz produces stronger physical effects and higher sonoluminescence per bubble, whereas frequencies between 200 and 800 kHz give rise to higher sonochemical yields. Similarly, s

Abstract:

Sonochemistry uses ultrasound to improve or modify chemical reactions. Sonochemistry occurs when the ultrasound causes chemical effects on the reaction system, such as the formation of free radicals, that intensify the reaction. Many studies have investigated the synthesis of nanomaterials by the sonochemical method, but there is still very limited information on the detailed characterization of these physicochemical and morphological nanoparticles. In this comprehensive review, recent advances in the sonochemical synthesis of nanomaterials based on iron oxide nanoparticles (Fe3O4NP), gold nan

Abstract:

We report a sonochemical method of functionalizing superparamagnetic iron oxide nanoparticles (SPION) with (3-aminopropyl)triethoxysilane (APTES). Mechanical stirring, localized hot spots and other unique conditions generated by an acoustic cavitation (sonochemical) process were found to induce a rapid silanization reaction between SPION and APTES. FTIR, XPS and XRD measurements were used to demonstrate the grafting of APTES on SPION. Compared to what was reported in literature, the results showed that the silanization reaction time was greatly minimized. More importantly, the product displaye
