A sonochemical process has been developed for the insertion of tin nanoparticles into mesoporous carbon, giving a product which was used as a building block for the anode of a rechargeable Li battery; the electrode could deliver a reversible capacity of 400 mAh gr(-1)(C + Sn) at 100% cycling efficiency, which is higher than that of graphite electrodes.

We report the sonochemical synthesis of copper(I) hydride (CuH) by the ultrasonic irradiation of a copper(II) aqueous solution. A reaction mechanism based on the reduction of copper(II) by the ultrasound-generated hydrogen atoms is discussed. To the best of our knowledge, this is the first time that a metal hydride has been synthesized through sonochemistry.

A facile, versatile, and one-pot sonochemical synthesis of polydopamine (PDA)-nanocapsules from dopamine is reported. The nanocapsules (227 ± 25 nm) can encapsulate hydrophobic substances while retaining the reactivity of PDA toward nucleophilic reactions, enabling facile surface modification for different applications. PDA nanocapsules are nontoxic to mammalian cells while Cu-containing PDA ca...

Sonochemical preparation of composite nanoparticles were performed in an aqueous solution. The reduction rates of metal ions and the size of the formed metal nanoparticles could be control by using various ultrasonic parameters. In addition, control of the nanostructure of these particles were succeeded.

We report a remarkably facile one-pot sonochemical approach to prepare protein microspheres whose shells are covalently decorated with a mannosyl derivative to target Escherichia coli (E. coli), while their cores are encapsulated with tetracycline. Conjugated microspheres induced the agglutination of E. coli and increased the anti-bacterial activity of the encapsulated tetracycline by five fold.

A convenient sonochemical method is described for the preparation of polystyrene functionalized graphenes starting from graphite flakes and a reactive monomer, styrene. Ultrasonic irradiation of graphite in styrene results in the mechanochemical exfoliation of graphite flakes to single-layer and few-layer graphene sheets combined with functionalization of the graphene with polystyrene chains. T...

The structural influence of graphene oxide (GO) on laser desorption/ionization mass spectrometry (LDI-MS) analysis of small molecules was systematically investigated by using size-fractionated GO. For fractionation of GO, pH-assisted centrifugation, sequential vacuum filtration, and sonochemical cutting processes were employed and the size-fractionated GO was thoroughly characterized to underst...

Two-dimensional MoS2-based composite has remarkable potential as an electrode material for advanced energy storage. However, the application of MoS2 is limited by its low electrical conductivity and cyclic stability. Herein, a novel three/two-dimensional (3D/2D) ternary nanostructured consisting MoS2/g-C3N4/reduced graphene oxide (rGO), denoted MCNG, synthesized using in-situ sonochemical-assis...
