High quality MOF-5 crystals of 5-25 mum in size were prepared for the first time using a sonochemical method in substantially reduced synthesis time (ca. 30 min) compared with conventional solvothermal synthesis (24 h).

tio2/zro2 nanocomposite was obtained by the sonochemical technique. in this method, two separate gels containing zirconium and titanium were prepared and mixed together. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4. the precursor titanium tetra isopropoxide (ttip) dissolved in isopropanol. mixing of titanium and zirconium gels was resulted in a yellow tio2/zro2 ...

The introduction of a strong acoustic field to an aqueous solution results in the generation of cavitation microbubbles. The growth and collapse of these microbubbles focuses and transfers energy from the macro-scale (acoustic wave) to the micro-scale (vapor inside the bubbles) producing extremely high localized pressures and temperatures. This unique energy focussing process generates highly r...

A novel sonochemical approach was developed for the synthesis of different core/shell structures of Fe3O4/SiO2/Ag nanocubes and SiO2/Ag nanospheres. The total reaction time of the three sonochemical steps for the synthesis of Fe3O4/SiO2/Ag nanocubes is shorter than that of the previously reported methods. A proposed reaction mechanism for the sonochemical functionalization of the silica and the...

Cyanide is a species of high toxicity that found mostly in industrial effluents such as electroplating, metal mining, metallurgy and metal cleaning processes. Entrance of it to existence environment contains very health hazardous. Objective of this study was the determination of efficiency of sonochemical technology for cyanide removal from aqueous solutions. In this study, it has been used fro...

The efficacy of sonochemical reactors in chemical processing applications has been well established in the laboratory scale of operation though at a given set of operating parameters and no efforts have been directed in terms of maximizing the free radical production. In the present work, the effect of different operating parameters viz. pH, power dissipation into the system, effect of additive...

We present sonogenerated magnesium-hydrogen sponges for effective reactive hard templating. Formation of differently organized nanomaterials is possible by variation of sonochemical parameters and solution composition: Fe2O3 nanorods or composite dendritic Fe2O3/Fe3O4 nanostructures.
