We model the collapse of a bubble by taking into account all the energy forms involved (i.e., mechanical, thermal, chemical, and radiative) and compare the calculated radical yields with sonochemical data in H2O. Water decomposition plays a critical role in the energy balance, but trails equilibrium even in bubbles collapsing at subsonic speeds. Integration of the equation of bubble motion coup...

mgo nanopartticels (np-mgo) in average size between 30—130 nm were prepared by sonochemistry method. some phenols have been converted to ortho-hydroxybezaldehyd by ortho-formylation using mgo nanoparticles and (ch2o)n in xylene and subsequently treated with aqueous nh2oh.hcl, affording the corresponding aldoxime in a one-pot procedure. moreover, this one-pot process, with two transformations, o...
