The x-ray diffraction analysis revealed pure FCC spinel phase and perovskite structure for MFO added in LFO respectively. FTIR analysis showed ʋ₁ and ʋ₂ absorption bands with wavenumbers 500 and 400 cm^-1. The frequency dependent dielectric parameters were investigated across abroad spectrum of AC frequencies, starting from 1 MHz to 3 GHz. Dielectric behaviors were found in well agreement with Maxwell – Wagner model followed by Koop’s theory, and hopping model at high frequency region. The Cole-Cole plot elaborated the conduction phenomenon. The nanocomposites demonstrate a stable and consistent dielectric constant (ε′) and dielectric loss (ε″) at moderate frequencies, making them highly suitable for applications in microwave devices, such as resonators, filters, and antennas where stable dielectric properties are crucial for efficient performance.

Ultrasonic vibration notably enhances NbC formation, refines grain size, and improves particle distribution uniformity. Optimal mechanical properties were observed at 330 W, with a 20.2 HV increase in microhardness and a 22.8 % reduction in wear volume, alongside a transition in wear mechanism from adhesive to fatigue wear. High-temperature oxidation tests at 800 °C for 60 h revealed the formation of Cr₂O₃, Nb₂O₅, NiO, and NiCr₂O₄ oxides, with the 330 W setting demonstrating superior oxidation resistance—2.67 mg/cm² wt gain and a 3.65 μm oxide layer, significantly lower than non-ultrasonic samples. However, as the ultrasonic power was further increased to 440 W, the cladding exhibited reduced microhardness, diminished wear resistance, and a decline in its ability to withstand high-temperature oxidation. This indicates that ultrasonic power should not exceed a certain limit, as excessive power can adversely affect the performance of the cladding.

Crucially, the obtained YCDs could be easily internalized by bacteria and emit bright yellow-green light inside the cells due to the small size (3.9 ± 0.6 nm) and large stokes shift (161 nm). Additionally, the YCDs display excellent effectiveness against pathogenic bacteria, especially for Gram-negative and resistant Gram-positive bacteria. The minimum inhibitory concentration for methicillin-resistant <em>Staphylococcus aureus</em> (MRSA) and <em>Escherichia coli</em> are 1.25 and 5 μg mL⁻¹, respectively.

In this study, density functional theory (DFT) calculations were employed to evaluate the catalytic performance of iron-based antiperovskite nitrides, AlFe₃N and GaFe₃N, for green ammonia synthesis via chemical looping. Stability analyses, including phonon dispersion, AIMD simulations, and elastic constants, confirm the dynamic, thermal, and mechanical robustness of both materials. Electronic structure results reveal metallic and ferromagnetic behavior, with a weaker Fe–N bond in GaFe₃N due to the higher electronegativity of Ga, which enhances charge transfer and surface reactivity. Thermodynamic calculations show that both hydrogenation and (nitridation) are spontaneous at low temperatures, with negative Gibbs free energy values up to 248 K for AlFe₃N and 415 K for GaFe₃N. Surface analysis identifies the (111) facet as the most reactive, where Ga-based nitride demonstrates stronger H₂ adsorption (-3.828 eV) and a more exothermic nitrogen vacancy formation energy (-2.429 eV) than Al-based nitride, while the latter shows slightly stronger N₂ adsorption (-1.405 eV). The associative Mars–van Krevelen mechanism is energetically more favorable for GaFe₃N, confirming its enhanced catalytic performance. These findings highlight the critical role of material composition in tuning catalytic behavior and establish AlFe₃N and GaFe₃N as promising catalysts for low-temperature, sustainable ammonia synthesis.

Simultaneously, PAM modulates the connectivity of metal-oxygen-metal (M-O-M) networks while introducing defect states, establishing a dynamic equilibrium between carrier transport enhancement and defect-mediated scattering. Optimization of molecular weight (150000) and polymer doping concentration (1 wt %) enabled synergistic regulation of nanocrystal interconnectivity and defect generation, achieving 90 % mobility retention of pure InO_x-TFTs (1.43 cm²/V.s) in InO_x/PAM-TFTs (1.38 cm²/V.s).
