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%. Additionally, in terms of efficiency, the proposed method reaches 98%, significantly higher than the 65%, 78%, and 85% achieved by the existing techniques. These findings indicate the efficiency of the proposed approach in improving the design and performance of piezoelectric energy harvesters, offering a promising solution for more efficient energy harvesting systems.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"15 2","pages":""},"PeriodicalIF":3.674,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the potential of carbonated pineapple peel waste, integrated with magnetic nanoparticles (PMNPs), for the adsorption-based removal of Congo red (CR) and methylene blue (MB) dyes. Various characterization techniques, including SEM, FTIR, and EDS, were used to analyze PMNPs before and after adsorption, while XRD, BET, VSM, and TGA were applied to assess the properties of pure PMNPs and their suitability for adsorption. The PMNPs exhibited a needle-like morphology and a high surface area of 6.836 m<sup>2</sup>/g, enhancing their dye adsorption capacity. At concentrations of 1.5 and 1.25 g/L, PMNPs achieved removal efficiencies of 93.15% for CR and 95.99% for MB. Thermodynamic analysis revealed the adsorption process to be spontaneous and exothermic. Computational modeling demonstrated that the Langmuir isotherm best described the adsorption process (<i>R</i><sup>2</sup> = 0.9930 for MB and 0.9891 for CR), while pseudo-first-order kinetics indicated physical adsorption. Artificial neural network (ANN) models further validated the experimental results, showing high prediction accuracy (<i>R</i> = 0.9948 for MB and 0.9939 for CR).
