Abstract

This manuscript reports the optical and structural characteristics of PVA/PANI composite polymer films synthesized through gamma-irradiation-induced in-situ polymerization. The in-situ formation of the conductive emeraldine salt phase of polyaniline (PANI) within the polyvinyl alcohol (PVA) binder matrix was achieved under different irradiation doses. The formation of the conductive PANI phase and the presence of Cl⁻ counter-ions were confirmed through FESEM morphological analysis and EDAX elemental mapping, respectively. XRD spectra further verify the semi-crystalline nature of the composite and indicate the structural role of PVA as a binder in stabilizing the polymeric composite system. Thermal behavior analysis using TGA reveals four distinct decomposition phases, with the most pronounced thermal transition observed in the composite irradiated at 50 kGy, suggesting enhanced structural interactions between PVA and PANI at this irradiation dose. Overall, the results demonstrate that gamma irradiation is an effective route for modifying the optical, structural, and thermal properties of PVA/PANI composites, making them promising candidates for optoelectronic and conductive polymer applications

Abstract

This study presents a comparative analysis of the structural and superconducting properties of YBa₂Cu₃O₇−δ (Y-123) and Y₂Ba₄Cu₇O₁₅−δ (Y-247) superconductors synthesised via a thermal treatment method at 980 °C. Metal nitrates were used as starting precursors, with polyvinylpyrrolidone (PVP) serving as a capping agent to enhance dispersion and control microstructure. X-ray diffraction (XRD) confirmed that Y-123 and Y-247 were the dominant phases in their respective samples, although minor peaks of BaCuO₂ were detected, indicating the presence of secondary phases. Scanning electron microscopy (SEM) revealed that Y-247 exhibited larger grain morphology and higher porosity than Y-123, suggesting that the chosen sintering temperature exceeds the thermal stability range for the Y-247 phase. Electrical resistivity measurements showed a single superconducting transition for both samples, with Y-123 exhibiting a sharper transition width (ΔTc = 8.1 K) compared to Y-247, indicating better grain connectivity and phase uniformity. Energy dispersive X-ray spectroscopy (EDX) supported the elemental presence of Y, Ba, Cu, and O in both samples, though variations in stoichiometry were attributed to secondary phases. The observed expansion in the c-axis lattice of Y-247, combined with its higher porosity, points to oxygen loss during sintering, which contributes to the reduced superconducting performance. Overall, the results confirm that both Y-123 and Y-247 can be successfully synthesised using a simple and environmentally friendly thermal treatment method. However, Y-123 exhibits better structural integrity and superconducting performance at the high sintering temperature of 980 °C, making it a more promising candidate for large-scale production of bulk high-temperature superconductors.

Abstract

YBa₂Cu₃O₇₋δ (Y123) superconductors is a widely studied high-temperature superconductor due to its high critical temperature, Tc and strong flux pinning properties. In this study, Y123 samples were synthesized via a thermal treatment method under two sintering conditions which were open air and oxygen flow. Structural, microstructural, and superconducting properties were evaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and AC susceptibility measurements. XRD analysis revealed that all Y123 samples exhibited predominantly Y123 phase with orthorhombic structure, with minor secondary phases. The Y123 sample prepared in an open-air condition exhibited larger grain size (0.698 µm), lower porosity, and fewer impurities compared to sample prepared in the oxygen flow condition. AC susceptibility showed a higher Tc-onset exhibited at 92.1 K in the open-air sample, indicating better grain connectivity. These results suggest that open-air sintering offers a simpler, cost-effective route for enhancing Y123 superconductor performance.

Abstract

In this work, Pr0.7Ba0.3MnO3 (PBMO) was synthesised using a thermal treatment method with sintering temperature ranging from 800 °C to 1100 °C. X-ray diffraction (XRD) confirmed the formation of pure PBMO phase at 1100 °C, while lower sintering temperatures led to the presence of secondary phase, particularly Pr(Mn2O5). Microstructural analysis revealed significant grain growth with rising sintering temperatures, accompanied by enhanced crystallinity and reduced secondary phases. Magnetic measurements indicated ferromagnetic behaviour at room temperature for all samples. However, the electrical resistivity demonstrates an unexpected increase with sintering temperature, attributed to the influence of secondary phase at lower sintering temperatures and grain growth in the pure PBMO phase at higher sintering temperatures. Additionally, microstructural defects such as oxygen non-stoichiometry or porosity might further contribute to the suppression of the metal-insulator transition temperature. Overall, this study highlights the significant role of sintering temperatures in controlling the phase purity, microstructure and physical behaviour of PBMO samples, offering valuable insights for their potential applications in spintronics or magnetic sensing devices.

Abstract

This study focuses on the synthesis and characterization of an anti-radon photocurable nanocoating formulated using a UV-curable formulation incorporated with functionalized carbon nanotubes (F-CNTs). The coating was prepared using Ebecryl 600 (urethane acrylate oligomer) and TMPTA (monomer), with GPTMS as a coupling agent and various photoinitiator combinations. Different F-CNT loadings ranging from 0.1 to 0.9 wt% were studied to evaluate their effects on coating performance. The samples were cured under UV irradiation for 2–20 passes to investigate the influence of exposure time on polymer crosslinking. Characterization analyses including pendulum hardness, Fourier-transform infrared spectroscopy (FTIR), viscosity, gel content, and radon gas permeability were performed. Results indicated that the incorporation of F-CNTs enhanced the mechanical strength and crosslinking density of the coating. The optimal formulation exhibited a hardness of 150.33 s (BAPO + 8 passes) and a gel content of 97%. Furthermore, radon concentration measurements showed a 28.9% reduction after applying a single coating layer, confirming the coating’s potential as an effective barrier for radon gas mitigation.

Abstract

Upcycling is an effective approach to reduce plastic waste, polyethylene terephthalate (PET) and promote sustainability. Plastic bottles usually were made from PET polymer and a raw material to produce carbon nanomaterials (CNMs). CNMs are synthesized using chemical vapor deposition (CVD) process and purified to eliminate catalysts and unwanted compounds. Various catalysts were used to investigate the economic and effective in producing the CNMs. Metal catalysts such as ferrocene, cobalt and iron are the important elements in the CVD process as they provide surfaces for carbon to attach. CNMs morphology and graphitic structure were observed from Raman analysis and TEM analysis. The application of upcycling offers the advantage of utilizing low-cost raw materials to produce higher-value products, providing additional benefits.
