“…To prepare liquid containing aluminium NPs suspended in vinyl alcohol monomer, an electric exploding wire technique was used (Fan et al, 2020;Alsaad et al, 2021;Tang et al, 2015). This method is considered one of the most environmentally friendly methods for preparing NPs of metallic materials (Tang et al, 2015;Hussein and Kadhem, 2021;Abdulla et al, 2022;Bai et al, 2019;Tanaka et al, 2021;Ghorbani, 2014;Abbass and Kadhem, 2018). To produce Al/PVA films, a plasma jet system was used because it is an easy, inexpensive, and efficient way to produce thin films (Abbass and Kadhem, 2018;Nikiforov et al, 2015;Gencer et al, 2008).…”

Alumina thin films have significant applications in the areas of optoelectronics, optics, electrical insulators, sensors and tribology. The novel aspect of this work is that the homogeneous alumina thin films were prepared in several stages to generate a plasma jet. In this paper, aluminium nanoparticles suspended in vinyl alcohol were prepared using exploding wire plasma. TEM analysis was used to determine the size and shape of particles in aluminium and vinyl alcohol suspensions; the TEM images showed that the particle size is 17.2 nm. Aluminium/poly vinyl alcohol (Al/PVA) thin films were prepared using this suspension on quartz substrate by plasma jet technique at room temperature with an argon gas flow rate of 1 L/min. The Al/PVA thin films were thermally converted to alumina films, where they were annealed at different temperatures (700, 800, or 900°C). X-ray diffraction (XRD), atomic force microscopy (AFM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) techniques were used to characterise these thin films before and after annealing process. The diffraction patterns of the prepared thin films before subjecting them to the annealing process indicated the presence of peaks belonging to aluminium and PVA; however, the diffraction patterns and FTIR spectra obtained for these films after the annealing process showed peaks indicating the formation of alumina films of different phases. AFM and SEM investigations proved that the formed particles for all prepared films before and after the annealing process were similar in size and almost spherical; the diameter of the particles was on the order of a few nanometres. To control the properties of prepared thin films, the plasma which was used to produce thin films is diagnosed spectrophotometrically. The generated plasma was diagnosed using optical emission spectroscopy to estimate the electron temperature Te; the electron temperature was 1.925 eV.

“…Sindhu et al found that the geometric mean size was smallest in helium ambiance compared to argon and nitrogen gas in both experiment and simulation due to the higher thermal conductivity (cooling rate) of helium [ 12 ]. However, the rapid phase transition of the exploding wire induces surface flashover, which causes incomplete vaporization/atomization, increasing the inhomogeneity of the explosion products [ 13 , 14 ]. Additionally, the development of electro-thermal instability, characterized by periodic striations, can increase the size range of the nanoparticles [ 15 ].…”

Nanomaterials with unique structural and properties can be synthesized by rapid transition of the thermodynamic state. One promising method is through electrical explosion, which possesses ultrafast heating/quenching rates (dT/dt~109 K/s) of the exploding conductor. In this study, experiments were performed with fine metallic wire exploding in liquid nitrogen (liq N2, 77 K) under different applied voltages. For the first time in the literature, the physical image of the electrical explosion dynamics in liq N2 is depicted using electro-physical diagnostics and spatial-temporal-resolved photography. Specifically, the pulsation and collapse processes of the vapor bubble (explosion products) have been carefully observed and analyzed. As a comparison, an underwater electrical explosion was also performed. The experimental results suggest that the vapor bubble behavior in liq N2 differs from that in water, especially in the collapse phase, characterized by secondary small-scale bubbles in liq N2, but multiple bubble pulses in water; correspondingly, the products’ characteristics are discrepant.

“…They proposed a nanoparticle formation mechanism that is caused by the condensation of primary particles produced in the early stages of wire electrical explosions. Bai et al [20] studied the electrical explosion characteristics of Al wire in ambient gas and considered that the explosion process in Ar has longer breakdown development time and greater deposition energy than that in He. It can be seen that Ar is more suitable as a protective gas in Al wire electrical explosion, and is more widely used.…”

In order to study the evolution of nanoparticles during aluminum wire electrical explosion, a nanoparticle formation model considering layered motion was developed, and an experimental system was set up to carry out electrical explosion experiments of 0.1 mm and 0.2 mm Al wires. The characteristic parameters and evolution process during the formation of nanoparticles were calculated and analyzed. The results show that the maximum velocities of the innermost and outermost layers are about 1200 m·s-1 and 1600 m·s-1, and the velocity of the middle layer is about 1400 m·s-1, respectively. Most of the nanoparticles are formed in the temperature range of 2600 ~ 2500 K. The characteristic temperature for the formation of aluminum nanoparticles is ~ 2520 K, which is also the characteristic temperature of other parameters. The formed nanoparticles diameter distribution ranging from 18 nm to 110 nm, and most of them are distributed near 22 nm.The variation of saturated vapor pressure determines the temperature distribution range of particle nucleation. There is a minimum critical diameter of particles (~ 25 nm), particles smaller than the critical diameter can grow into larger particles during surface growth. Particle motion has an effect on the surface growth and aggregation process of particles, and also on the distribution area of larger diameter particles. The simulation results are in good agreement with the experiments. It provides a method to estimate the size and distribution of nanoparticles, which is of great significance to understand the formation process of particles during the evolution of wire electrical explosion.
