In the free field, it was found that salted water temperature affected the maximum radius, minimum first contraction radius, expansion time and collapse time of bubble.

Further measurements using high-frequency pressure testing system revealed that as salted water temperature increased, the pressure peak of shock wave and relative energy gradually decreased.

WPI solutions were subjected to ultrasonic treatment at two power levels (300 W and 600 W) for durations of 10 and 20 min. The findings reveal a fascinating interplay between ultrasonic parameters and protein behavior: at 300 W, the treatment induces protein unfolding, while at 600 W, it promotes the formation of large aggregates. These changes are accompanied by significant alterations in secondary structures, with a reduction in β-sheet and α-helix content at 300 W, followed by their re-enhancement at 600 W. Notably, ultrasonication at 600 W significantly enhances di-tyrosine formation, sulfhydryl content, and surface hydrophobicity, compared to untreated samples. Zeta-potential measurements demonstrate a decrease after 10 min of treatment at both power levels, but an increase is observed after 20 min, indicating dynamic shifts in surface charge. Additionally, ultrasonic treatment elevates interfacial tension. WHC increases by 2.2-fold and 3.2-fold after 20 min of treatment at 300 and 600 W, respectively. At 600 W, a marked reduction in solubility and a substantial increase in turbidity are observed, contrasting with the outcomes at 300 W.
