Enhancing the energy-storage performance of lead-free dielectric ceramics is essential for developing environmentally sustainable capacitors and power devices. NaNbO$_3$, a promising perovskite, exhibits considerable potential for dielectric applications but is limited by poor densification and high dielectric loss. In this work, the effects of tantalum (Ta) doping at varying concentrations $\text{NaNb}_{1-x}\text{Ta}_x\text{O}_3$, with $x = 0.05, 0.10, \text{and } 0.15$, corresponding to 5%, 10%, and 15% Ta substitution on the crystal structure, microstructure, and electrical properties of NaNbO$_3$ ceramics were systematically investigated. X-ray diffraction (XRD) confirmed phase purity an... More >
The growing demand for sustainable materials in green flexible electronics calls for alternatives to petroleum-derived polymers, which are non-biodegradable, resource-intensive, and environmentally harmful. This study presents the fabrication of bio-composite films using water hyacinth derived cellulose nanofibrils (CNF), blended with polyethylene oxide (PEO) and reinforced by functional nanofillers such as barium titanate (BTO), silver nanowires (SNP), and carbon nanotubes (CNT). The nanocomposite films (NCF) were produced by solution casting and systematically characterized for morphological, dielectric, mechanical, thermal, and chemical properties. Scanning electron microscopy analysis re... More >
