“…As was reported in our previous study, 26 BaO bond formation manifests itself as a band at the vicinity of 693 cm −1 . Additionally, the BaO FTIR spectrum has two bands at 855 and 1413 cm −1 which are associated with the asymmetric vibration mode of

ions and absorption of CO by barium oxide particles, respectively 32,33 . From this point of view, due to the presence of BaO contribution in the composites, new band formation at the vicinity of 693 cm −1 is observed in the composites, which become more evident at the relevant wavenumber, especially at high BaO additive concentrations (4% and 5%).…”

In this study, it is aimed to produce a non‐carcinogenic and environmentally friendly biodegradable multi‐functional PVA‐based nanocomposite by improving its electrical properties and mechanical strength. For this purpose, BaO nanoparticles produced by the co‐precipitation method, have been added to the PVA matrix between 0.5% and 5% by mass, and thick film nanocomposites have been produced. The structural properties of the samples and the doping particle have been investigated by FTIR, SEM, and XRD. While electrical measurements have been carried out by an impedance analyzer at room temperature between 20 Hz and 15 MHz frequency, tensile tests have been performed by a mechanical tensile device. The addition of 5% BaO nanoparticles not only increased the energy storage capability of PVA significantly (117%) but also managed to reduce the loss factor considerably (77%). Moreover, compared to other samples, PVA/5% BaO nanocomposite also stands out with its higher ac conductivity within the mid‐and high‐frequency range. Furthermore, the 5% BaO nanoparticle additive provided a serious benefit to the mechanical strength of PVA by improving its Young's modulus, toughness, and stress at the break at different rates. As a result, the BaO nanoparticle additive makes PVA a more functional material as well as more technologically desired.

The dielectric characteristics of barium oxide: Therm500 nanofluids were investigated at a static frequency in this study. Barium oxide: Therm500 nanofluids are made by dispersing barium oxide nanoparticles in Therm500 (base fluid) using a sonicator. The static dielectric measurements were made with a frequency domain reflectometry (FDR) sensor. At various temperatures, the values of several dielectric properties, including dipole moment (μ), molar polarization (P), excess dielectric constant ( ε E ), static dielectric constant ( ε O ), and excess dipole moment ( μ E ), have been measured for BaO: Therm500 nanofluids. Kirkwood factor and Bruggman factor were also computed and presented. The fluctuations in dielectric properties concerning six distinct combinations including 0.001 grams, 0.002 grams, 0.003 grams, 0.004 grams, 0.005 grams, and 0.006 g of nanofluid systems and four different temperatures such as 300 K, 303 K, 313 K, and 323 K are investigated in terms of intermolecular interactions. At all temperatures, the abovementioned dielectric properties BaO: Therm500 nanofluids are positive-negative variations across the whole combination range suggesting in nanofluids the existence of molecular interactions. Synchronization in both parallel and antiparallel of the dipoles in the fluid’s mixture are verified by the Kirkwood factor. The Bruggman factor depicts the divergence from the linear relationship in nanofluids, indicating molecular interactions. Dielectric properties of BaO: Therm500 are being studied to understand better their physical, technical, chemical, industrial, laboratory, biological, and pharmaceutical applications.

This study describes a straightforward and affordable photolysis approach for the large-scale production of barium oxide nanoparticles (BaO-NPs). BaO-NPs were synthesized Using the UV-Irradiation Technique. The structural, morphological, compositional, and optical characteristics were studied by XRD, SEM, EDX and PL. the The BaO-NPs crystallite size was determined to be 14.6 nm. the morphology of BaO nanoparticles which demonstrated the existence of nanoparticles in the produced materials. and predicted bandgap of the nanoparticles was determined to be 3.26 eV by photoluminescence spectroscopy. BaO NPS that have been produced exhibit desirable adsorbent behavior for cibacron blue dye in their aqueous solutions. the effects of contact time, adsorbent mass, temperature, and starting cibacron blue dye concentration were investigated. The dye isotherm adsorption demonstrated good Freundlich agreement. The ∆H, ∆S, and ∆G parameters were calculated using a thermodynamic Van't Hoff equation, and the results were 9.69701 kJ/mol, 0.813 kJ/mol K, and 9.403 kJ/mol, respectively. Additionally, the kinetic investigation revealed that the adsorption exhibited pseudo-second-order behavior.
