Abstract This work investigates the effect of a modified nickel‐doped metal‐organic framework (Ni‐ZIF‐67) as filler on thermal, mechanical, and water vapor permeability properties environmentally friendly waterborne polyurethane (WPU). The facile greener ultrasound (sonochemical) technique is developed to prepare multifunctional Ni‐ZIF‐67@WPU nanocomposites, exhibiting superior crystallinity un...

Suspensions of graphene, prepared from graphite foil by sonochemical exfoliation, have been treated with new nonpolar pyrenebutyric amides. The assemblies, in suspension and after deposition on solid supports, were characterized by NMR, absorption, and fluorescence spectroscopy and by transmission electron microscopy, where the well-defined shape and size of an appended [60]fulleropyrrolidine u...

Porous Cu(2)O nanospheres with controllable structures were successfully synthesized by using ascorbic acid as the reducing agent and beta-cyclodextrin (beta-CD) as the capping agent via a sonochemical route, which was proved to be a green and convenient method for the controlled synthesis of porous Cu(2)O nanospheres. The crystal phase of the product was determined by the concentration of asco...

Variation in intensity of scattered light from cavitation bubbles in an ultrasonic standing wave field at different contents of dissolved air is studied experimentally. The number of cavitation bubbles that repeat expansion and contraction correlates with the sonochemical reaction yield and the evaluation of the number of bubbles is important for perspective on the yield. Peak-to-peak of intens...
