“…Apart from experimental parameters, external perturbations have also been employed to control the properties of NPs. LAL experiments in the presence of external fields such as electric field, magnetic field, and temperature field have been studied by various research groups [25][26][27][28][29][30][31][32][33][34][35][36][37].…”

The present study aims to investigate the changes in the properties of nanoparticles (NPs) and cavitation bubble dynamics on applying an external electric field during laser ablation in liquid (LAL). Investigating electric field assisted laser ablation in liquid (EFLAL) is crucial since phenomena such as plasma charging effect and electrostatic pressure have important role in determining the size, shape, and crystallinity. of the NPs. With this motivation, the present study has been conducted with different electric fields of 0, 100, 500 and 1000 V/cm to probe the effect of an external electric field on the dynamics of EFLAL. The charging effect observed on NPs during cavitation bubble dynamics was also investigated at these field intensities. The size of NPs witnesses a reduction from ~30 nm without electric field to ~19 nm in presence of electric field. Also, a significant narrowing of the size distribution by over 4 times was observed in the presence of electric field. This clearly demonstrates that EFLAL can be used to obtain NPs with uniform size distribution. Moreover, NPs of different shapes have also been observed by varying the electric field intensities (100 and 1000 V/cm). The effect of the external electric field on the dynamics of the cavitation bubble produced during EFLAL has been probed using shadowgraphy technique. It has been observed that the bubble size increases with the presence of an electric field. The estimation of the bubble pressure in the presence of an electric field has revealed that the implosion bubble pressure is significantly lower than pressure in the absence of the field. The results obtained for NPs have been correlated to the changes in bubble parameters in this work.

“…Cavitation bubbles exist widely in nature, e.g., the snapping shrimp uses cavitation bubbles formed by the rapid closure of its claws to stun its prey; in a fast flowing system, cavitation bubbles are prone to occur if the channel suddenly narrows and then widens. The phenomenon of cavitation in the liquid is concerned because of its damage to hydraulic machinery and ship propellers (Sezen et ) (e.g., liquid jet, free radicals formation, radiation pressure, and acoustic microstreaming) caused by the bubble oscillations, cavitation has been contributed to various applications such as water treatment (Ferkou et al, 2015), petroleum hydrocarbons degradation (Lei et al, 2020), nanoparticle synthesis (Pokhrel et al, 2016), and so on.…”

In this paper, the dynamics of an acoustic bubble with a constant charge in compressible liquid are investigated numerically, which is based on the Gilmore-NASG model to estimate the radial oscillations. The cavitation effects are enhanced due to the presence of the charge on the bubble surface. The obtained results from the present model are compared with that calculated by the previous model within a wide range of parameters (e.g., charge, acoustic pressure amplitude, ultrasound frequency, and liquid temperature). The similar influences of these parameters on bubble collapse intensity can be observed from both models. Since the present model fully considers the compressibility of gas and liquid, it can be applied to a wider parameter range and leads to the larger predicted values. The research in this paper can provide important insights about the effects of charge on bubble dynamics and the acoustic cavitation applications (e.g., sonochemistry, water treatment, and food industry).
