Ultrasonics and sonochemistry: Editors’ perspective

Spherical Binderless 4A/5A Zeolite Assemblies: Synthesis, Characterization, and Adsorbent Applications

“…To effectively promote homogeneous nucleation and speed up crystallization, we employed vacuum impregnation to induce forced infiltration and ultrasound pretreatment to take advantage of the acoustic cavitation in sonochemistry [32]. Without ultrasonic pretreatment, the obtained zeolite spheres were, spatially, not uniform, even with the aid of vacuum impregnation (Figure 6c,d).…”

“…XRD pattern (Figure 7e) and Rietveld refinement fitting (Figure S8) confirmed the formation of pure-phase LTA crystals with slight crystal orientation. Due to the kinetic restrictions at cryogenic temper- To effectively promote homogeneous nucleation and speed up crystallization, we employed vacuum impregnation to induce forced infiltration and ultrasound pretreatment to take advantage of the acoustic cavitation in sonochemistry [32]. Without ultrasonic pretreatment, the obtained zeolite spheres were, spatially, not uniform, even with the aid of vacuum impregnation (Figure 6c,d).…”

Exploiting Benefits of Vaterite Metastability to Design Degradable Systems for Biomedical Applications

“…Thus, for instance, in further elaboration of this idea, the au thors have designed the photosensitizer-loaded vaterite carriers with a potential for US imaging-guided photodynamic destruction of cancer cells [151]. In the work [45], photosensitizer-loaded vaterite carriers were tested for their ability to destruct tumors under the US treatment (0.89 MHz) followed by the light irradiation US of certain intensity producing the acoustic cavitation, which effects, such as the for mation of microjets and shock waves [154], can cause cytotoxic effects in tumor cells [155] Figure 13. Exploiting of CO 2 bubbles' generation, which occurs during the dissolution of vaterite particles, for US imaging of tumors.…”

Antisolvent fabrication of monodisperse liposomes using novel ultrasonic microreactors: Process optimization, performance comparison and intensification effect

“…More importantly, the microscale channel or complex passive mixed structures make them highly susceptible to particle fouling or clogging, leading to poor repeatability and applicability [17] , [19] , [22] . Ultrasonic/acoustic [23] , [24] , [25] microreactors combined an external ultrasonic generator and microchannel can efficiently solve the above challenges, decoupling from the flow rate and preventing particle clogging [26] . Typically, the sharp-edge acoustic streaming (SEAS) mixer [27] and the ultrasonic microreactor (USMR) [28] , [29] , [30] , [31] are two kinds of active ultrasonic/acoustic microreactors.…”
