Effect of ultrasonic frequency and surfactant addition on microcapsule destruction

Periodicity in ultrasonic atomization involving beads-fountain oscillations and mist generation: Effects of driving frequency

“…, Qi et al [27] , Collins et al [28] , and Blamey et al [29] ; the latter by, e.g. , Neppiras and Noltingk [30] , Kojima et al [21] , Ramisetty et al [31] , and Inui et al [32] . Cavitation bubbles, if present, could contribute to such selective separation from a multicomponent system like alcohol–water solutions—in symbiosis with capillary instabilities—associated with UsA ( e.g.…”

Effect of ruptured cavitated bubble cluster on the extent of the cell deformation by ultrasound

“…The action of ultrasound on cells is caused by cavitation bubbles [5] . The resonant frequency of bubble oscillation and the large amount of broadband noise generated by cavitation promote cell deformation, and cell damage is caused by the shear stress generated by bubble rupture acting as a local force on the cell surface.…”

The physical, mechanical, thermal and barrier properties of starch nanoparticle (SNP)/polyurethane (PU) nanocomposite films synthesised by an ultrasound-assisted process

“…The high intensity irradiation of US may cause the destruction of microcapsules in the solution. Inui et al [12] studied the phenomenon of destruction of microcapsules of starch under US irradiation. The shear stress induced due to the collapse of bubbles in solution is one of the reasons for the physical destruction of structure of starch [12] .…”
