The nanostructures were synthesised using the pulsed Nd-YAG ablation technique, which entailed submerging small, high-quality tin particles in deionised water. The particles were coarsely crushed manually, filtered, and compacted into a solid tablet for 60 min using a 5-t hydraulic press. This production method utilised a pulse count of up to 200 laser shots, a wavelength of 1064 nm, spot size of 2.3 mm, focal length of 10 cm, and an energy of 500 mJ to examine the influence of surface shape on antibacterial activity levels. X-ray diffraction (XRD) analysis identified rhombohedral crystals mainly characterised by three Bragg peaks. Scanning electron microscopy (SEM) of the surface showed distinct and reasonably homogenous semispherical nanoparticles (NPs) rather than the expected porosity. The NPs exhibited an average size of 193.53 nm, in agreement with electron dispersive spectroscopy (EDS), which indicated that the oxygen-to-tin ratio closely approximated that of tin oxide (SnO<sub>2</sub>). In addition, the vibrational spectra measured with a Fourier transform infrared (FTIR) spectrometer indicated the synthesis of amber-coloured SnO<sub>2</sub> NPs, confirming their formation by the preparation process, as well as their light scattering and absorption characteristics. In addition, using UV–visible spectroscopy, the resulting energy gap was 2.4 eV, within the normal range of energy gap for SnO<sub>2</sub>. The generated NPs were discovered to suppress the growth of fungi and bacteria, indicating that they may prevent the development of these entities.

One of the primary challenges with piezoelectric harvesters is their high resonant frequencies, which often do not align with the lower natural frequencies of ambient vibrations, limiting their efficiency. The goal of this research is to propose a new technique to optimize the design of PEHs, enhancing voltage output and power conversion efficiency. The proposed method combines an Arithmetic Optimization Algorithm to optimize the harvester’s dimensions with a Dual Temporal Gated Multi-Graph Convolution Network (DTGMGCN) to forecast resonant frequency and harvested voltage. The principal objective is to reduce resonant frequency errors and enhance energy conversion efficiency. The results, implemented on a MATLAB platform, demonstrate that the proposed method outperforms the existing techniques, such as robust chaotic Harris Hawk optimization, K-Nearest Neighbor Algorithm, and Heaviside Penalization of Discrete Material Optimization. The existing techniques show errors of 0.04%, 0.06%, and 0.08%, while the proposed method achieves an error of only 0.02%.
