Describes the ability a managing the symmetric sonochemical reactor for physic-chemical treatment of chemically pure water, true and colloidal aqueous solutions, as well as disperse systems with the speed of sound in them more than at water. Such reactors are useful, for example, in the food industry, where are processed of different concentrations the solutions NaCl. Demonstrated that the deve...

This review article summarizes the last few decades of research on nickel hydroxide, an important material in physics and chemistry, that has many applications in engineering including, significantly, batteries. First, the structures of the two known polymorphs, denoted as α-Ni(OH)2 and β-Ni(OH)2, are described. The various types of disorder, which are frequently present in nickel hydroxide mat...

In the present study, ZnO nanostructure has been synthesized by different methods, namely coprecipitation, hydrothermal and sonochemical methods. After comparison of the morphology and photocatalytic activity of ZnO samples prepared via different methods, the best method (sonochemical method) was used for synthesis of Ni-ZnO nanoparticles with different concentrations of nickel. Furthermore, st...

The Mo(13) clusters we previously reported were derived from MoS(2) flakes prepared from bulk MoS(2), although the nature of the precursor species was not fully understood. The existence of the clusters in the condensed phase was a question. Here we report the preparation of MoS(2) nanoflakes from elemental precursors using the sonochemical method and study the gas-phase clusters derived from t...

Lignocellulosic biomass represents a natural renewable chemical feedstock that can be used to produce high value-added chemicals and platform molecules. Nowadays, there are extensive studies on a variety of aspects concerning the valorization of lignocellulosic biomass into desirable products. Among the current technologies for biomass conversion some require extreme conditions along with high ...

Sphere-like cadmium molybdate (CdMoO4) nanostructures have been synthesized by a large scale and simple sonochemical method by using Cd(Sal)2 (Sal=salicylidene) and Na2MoO4.2H2O for the first time. The effects of sonochemical irradiation time, sonochemical power, temperature, solvent, surfactant and cadmium source were considered to obtain a controlled shape. The as-prepared nanostructured cadm...

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 with high phase purity, then sol-gel another phase, crystals, while Ag3PO4 from precursor media. The research showed had smallest crystallite particle sizes of 9.5 232.7...
