“…In pulsed laser ablation in liquids (PLAL), the interaction of the laser radiation with a target immersed in a liquid promotes the extraction of material from the surface of the target in the form of NPs, resulting in the fabrication of nanostructured colloids that can be manipulated and manufactured more safely, avoiding inhalation risk . The NPs synthesized by applying laser techniques exhibit outstanding properties in fields such as catalysis, medicine, and energy . In the present paper, the synthesis of a solar nanofluid composed of tin NPs suspended in ethylene glycol through PLAL is reported.…”

Solar energy is available over wide geographical areas and its harnessing is becoming an essential tool to satisfy the ever-increasing demand for energy with minimal environmental impact. Solar nanofluids are a novel solar receiver concept for efficient harvesting of solar radiation based on volumetric absorption of directly irradiated nanoparticles in a heat transfer fluid. Herein, the fabrication of a solar nanofluid by pulsed laser ablation in liquids was explored. This study was conducted with the ablation of bulk tin immersed in ethylene glycol with a femtosecond laser. Laser irradiation promotes the formation of tin nanoparticles that are collected in the ethylene glycol as colloids, creating the solar nanofluid. The ability to trap incoming electromagnetic radiation, thermal conductivity, and the stability of the solar nanofluid in comparison with conventional synthesis methods is enhanced.

“…Despite a couple of odd issues of a physical, compound and concentrated nature, a couple of strategies have been proposed to vanquish the above issues, including the decision of the reasonable liquid or settling trained professional, the upgrade of the focusing conditions and liquid levels, as well as the gathering of sifting and fluid components methodology by different liquid managing plans and the post irradiation of colloids [5,6]. The aim of this research is to prepare nanoparticles of aluminum by using a pulsed laser ablation.…”

This examination, pulsed laser ablation in liquids technology was used to synthesis of aluminum nanoparticles. A number of pulsed Nydmium Yak (Nd:YAG) laser with wavelength (1064 nm) , constant ablation energy (600 mJ), frequency (1 Hz) and pulse duration (10 ns), was utilized for an objective of unadulterated aluminum drenched in refined water. The primary, morphological, and optical properties were examined, including XRD for Al NPs has a polycrystalline structure and cubic phase. The planes ( 111) and ( 200) corresponding to peaks at (2θ=38.08° and 44.03°) which agreement with the JCPDS standard card no. (004-0787).(111) direction represents the strongest and the preferred peak. We determined the crystallite size found out by utilizing Scherrer's recipe it was (17.52) nm. Estimation of FTIR after effects of the pre-arranged aluminum showed an expansion of the connection between AL-O-H , C -O , C = C, and O-H Which have a place with the water particles utilized in the readiness interaction. Field Emission Scanning Electron Microscopy (FESEM) analysis were carried out.FESEM images of Al NPs prepared at 500 pulse relatively shapes like spherical, cubical and uniform were noted. It is clear from these pictures that the particle size is around (177.4 nm), Al NPs prepared at 600 pulses are in agglomerated form. Due to the agglomeration the particles look much bigger than their real size. It is clear from these pictures that the particle size is around (136.0 nm) and Al NPs prepared at 700 pulses are nearly spherical and cubical in shape with different sizes. The aggregation of Al nanoparticles is due to strong interactions.The average particle size of the NPs observed from FE-SEM images is (123.1 nm). The

Tin oxide nanoparticles (SnNPs) are very useful to be employed as an antibacterial agent for both gram-positive and gram-negative bacteria. In this present work, the synthesis of SnNPs was successfully carried out using the neodymium yttrium aluminum garnet (Nd:YAG) laser with a wavelength of 1064 nm, pulse duration of 7 ns, and a laser frequency of 10 Hz. Experimentally, a pulse Nd:YAG laser was directed and focused on a high-purity tin (Sn) metal, immersed in various liquid media including pure water and ethylene glycol. A brownish colloidal colour was produced both in pure water and ethylene glycol liquid media. Characterizations of tin oxide nanoparticles were made using UV-Vis, EDX, FTIR, and TEM. UV-Vis characterization produced absorbance values in pure water and ethylene glycol media of 1.314 a.u. and 1.119 a.u., respectively. TEM images show that the shape of tin oxide nanoparticles produced is spherical. Measurement of nanoparticle size distribution was made using image-J software and the average diameter of nano-size in the ethylene glycol medium is 12.55 nm, which is smaller than the size in the pure water of 19.98 nm. The EDX spectrum analysis results show that there are only Sn and O atoms in colloidal tin oxide nanoparticles (SnNPs). FTIR results show the formation of tin oxide (SnO2) spectrum at the wavenumber of 629.03 cm-1. The produced colloidal SnNPs were then applied as an antibacterial agent of E. coli using the disk diffusion method. Results certified that various concentrations of SnNPs of 10 ppm, 20 ppm, and 30 ppm gain the diameter of inhibition zone (DIZ) in sequence 6.50 mm, 6.75 mm, and 9.50 mm. Based on these experimental results, it shows that the higher the concentration of SnNPs given, the greater the ability to degrade and inhibit bacteria.
