However, its practical application is limited by insufficient catalytic activity. In this work, we propose lanthanum (La)-doped bismuth ferrite (LBF) as a means to enhance piezo-photocatalytic degradation of tetracycline hydrochloride (TC) in wastewater through band structure engineering. La doping reduced particle size from approximately 48.7 to 31.1 nm, significantly enhanced optical absorption, and narrowed the bandgap from 2.10 to 1.88 eV. The optimized LBF0.2 sample demonstrated superior piezo-photocatalytic performance, achieving a degradation rate of 0.069 min⁻¹ for TC, which is 8.6 and 3.2 times higher than those of pure piezo-catalysis and photocatalysis, respectively. This synergy is ascribed to the internal piezoelectric field of LBF0.2, which modifies the energy band structure, promotes photogenerated charge separation, and facilitates the production of reactive species for pollutant decomposition. Remarkably, the material retained ~ 96% efficiency after six consecutive cycles.

In the present work, tin (Sn)-doped zinc sulfide (ZnS) nanoparticles were successfully prepared through co-precipitation route followed by organic dye grafting—carminic acid (CA), pyrocatechol violet (PCV), and dithizone (DT)—and subsequently blended with poly(3-hexylthiophene) (P3HT) to develop hybrid bulk heterojunction solar cell. Structural and microscopic analyses using XRD, FTIR, UV–Vis, and SEM confirmed the successful doping, dye grafting, and favorable nanostructurization. Bandgap was tuned from 3.51 eV for the undoped ZnS to 3.01 eV by doping with Sn, which improves the absorption of visible light. Photovoltaic characteristics were assessed under simulated sunlight conditions using I–V characteristics. The reference device (P3HT-ZnS) exhibited modest power conversion efficiency (PCE) of 0.52%, whereas an increment to 0.87% was observed with doping alone using Sn doping. Surprisingly, the devices using the dye-sensitized Sn-ZnS nanohybrids improved significantly, and with the P3HT + Sn-ZnS + PCV cell achieving the highest efficiency of 2.23%, with short-circuit current density (J_sc) as 10.80 mA/cm² and an open-circuit voltage (V_oc) of 0.45 V. This improved performance is ascribed to the synergistic effect of doping with Sn and dye sensitization, which enhanced the light harvesting, charge separation, and hurt less recombination.

Transmission electron microscopy (sTEM) was used to identify CuO (NPs). Differential scanning calorimetry (DSC) was used to examine thermal parameters. Elastic factors, including toughness (T), yield strength (Y), Young’s modulus (E), and tensile strength (S), were investigated using the tensile test machine. Vickers microhardness tester was used to test the hardness and creep resistance. Wettability characteristics were measured using the Sessile Drop Method (SDM). X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses confirm that CuO NPs serve as effective nucleation sites, refining the microstructure and facilitating the formation of SnBi intermetallic compounds (IMCs). Differential scanning calorimetry (DSC) results showed a slight decrease in the melting point with increasing CuO nanoparticle content. Specifically, the melting temperature was reduced to 143.7 ℃ with the addition of 0.2 wt% CuO. This reduction enhances the alloy’s suitability for low-temperature soldering applications and indicates improved thermal stability. Mechanical testing reveals a significant improvement where the optimal composition, Sn-40Bi-1CuO, exhibited the highest ultimate tensile strength (77.91 MPa), elastic modulus (230.03 GPa) and maximum microhardness (21.65 gmf/mm²), indicating improved creep resistance and mechanical stability.
