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.

“…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].…”

“…In both cases it is seen that the NPs attain a size of B50 nm at 500 V m À1 while at 3000 V m À1 they decrease in size to B40 nm when the bubble collapses. In previous work by Razaghianpour et al, 53 it was observed that Cu NPs synthesized using pulsed laser ablation reduced in size from 28.7 nm at 0 V m À1 to 19.6 nm at 2500 V m À1 .…”

“…Previous works have reported that laser ablation of a copper target in DDW and ethanol leads to the formation of CuO NPs. [53][54][55] However, in this theoretical investigation, the nucleation of CuO in DDW could not be examined due to constraints related to the dielectric constant k l . 56 The pulsed laser ablation of copper in acetone results in the NPs getting surrounded by a carbon matrix which prevents NP oxidation.…”

“…With the advancement of science and technology, some high-tech contactless methods have also been applied to detect the mechanical properties of granular systems, such as acoustic emission [19], scanning electron microscope [20], X-ray computed tomography [21], and nuclear magnetic resonance [22]. However, these methods have not been widely implemented due to their strict requirements for environment and equipment, long scanning time, and especially the impossibility of in situ loading.…”

Deformation and Force Chain of Two-Dimensional Granular Systems under Continuous Loading

A continuous loading experiment of a two-dimensional granular system was carried out and the experimental data were obtained by digital image correlation (DIC). The deformation field of the granular system and the changing laws of the deflection angle and coordination number of the granules on force chains with time were obtained. Based on the granule element method, the quantitative calculation of contact force was realized, and the internal force chains of the granular system were identified. The effects of contact force between granules and mechanical parameters on the evolution of force chains in a two-dimensional granular system under line loads were analyzed. The formation, evolution, and reconstruction of force chains in a granular system during loading, as well as the influence of the force chain network evolution on the macroscopic mechanical properties of granules were discussed. The experimental results indicated that the evolution of force chains was directly related to the number, geometric properties, and permutation distribution of granules in direct contact with the external load.
