Abstract

Background: Polyvinylidene fluoride (PVDF) is widely utilized in electronic devices due to its piezoelectric properties, which can be enhanced through the incorporation of barium titanate (BT). However, the impact of various fabrication methods on the crystallinity and beta-phase content of PVDF/BT nanocomposites remains underexplored. Specific Background: Different manufacturing techniques, including 3D printing, electrospinning, solvent casting, and compression molding, influence the structural and functional properties of PVDF/BT composites. The crystallinity and beta-phase content of PVDF are critical for optimizing the dielectric and piezoelectric performance of these materials. Knowledge Gap: There is a lack of comprehensive studies comparing the effects of these fabrication techniques on the crystallinity and beta-phase enhancement of PVDF/BT composites, particularly concerning their dielectric, piezoelectric, and mechanical properties. Aims: This study aimed to investigate the impact of integrating BT into PVDF using various fabrication methods on the crystallinity and beta-phase formation. The goal was to determine how these modifications influence the material’s structural characteristics and, consequently, its electronic properties. Results: X-ray Diffraction (XRD) and Fourier-Transform Infrared Spectroscopy (FTIR) analyses revealed that 3D printing and electrospinning methods significantly enhanced the beta-phase content and crystallinity of PVDF/BT composites compared to solvent casting and compression molding. Scanning Electron Microscopy (SEM) confirmed improved morphological features in the PVDF matrix with these techniques. Novelty: This study provides new insights into how different fabrication methods can optimize the crystallinity and beta-phase of PVDF/BT nanocomposites, which are crucial for enhancing piezoelectric performance. Implications: The findings suggest that 3D printing and electrospinning are superior to traditional methods for fabricating PVDF/BT composites with enhanced piezoelectric properties. These results can guide the development of more efficient electronic devices by selecting appropriate fabrication techniques to achieve desired material properties.

Abstract

Objective:  Zinc oxide (ZnO) nanorods, a cornerstone of one-dimensional semiconductor nanostructures, have attracted profound research interest due to their unique combination of piezoelectricity, wide bandgap, and biocompatibility. While often treated as a wurtzite-structured constant, the lattice parameters (a, b, and c) of ZnO nanorods are not immutable. This review comprehensively examines the intentional engineering of ZnO nanorod lattice constants through various synthesis strategies, including doping with foreign elements, manipulation of growth parameters, and substrate-induced strain. Method: We delve into the fundamental mechanisms—such as ionic radius mismatch, formation of intrinsic point defects, and external stress—that lead to lattice expansion or contraction. Results: The consequential tuning of functional properties, most notably the bandgap via strain-induced piezoelectric effects, is critically analyzed. Furthermore, this review consolidates recent advancements demonstrating how precise lattice control enhances performance in applications ranging from piezotronics and optoelectronics to catalysis and sensing. Novelty: By synthesizing findings from a vast body of literature, this review aims to serve as a foundational guide for researchers seeking to exploit lattice engineering as a powerful tool for tailoring ZnO nanorods for next-generation technologies.

Abstract

Objective: Noise-induced hearing loss (NIHL) poses a significant risk to workers in high-noise environments, particularly in the oil industry. This study investigates the prevalence of NIHL and tinnitus among employees at Basra Oil Company. Method: Recent data indicates that 23% of workers exposed to noise experience hearing loss, compared to only 7% among those not exposed, and a preliminary assessment of hearing difficulty was conducted, revealing critical risk factors such as increased noise exposure and family history of hearing issues. Pure-tone audiometry (PTA) testing, performed on 354 workers, found that none showed significant hearing impairment, suggesting effective safety measures. Result: However, the gradual nature of NIHL necessitates ongoing monitoring and preventive strategies. Novelty: Recommendations include implementing regular hearing tests every six months, establishing comprehensive hearing conservation programs, and promoting awareness of noise hazards, with these measures aiming to safeguard the auditory health of workers and improve overall occupational safety.
