Abstract

High-temperature superconductor Bi2Sr2CaCu2O8+δ (Bi-2212) was successfully prepared using a thermal treatment method, starting with nitrate-based precursors. This study focused on how different sintering temperatures affect the material’s critical temperature, Tc. The process began with a pre-calcination step at 600 °C for 12 hours, followed by calcination at 820 °C for 24 hours. After that, the powder was pressed into pellets and sintered at 830 °C, 840 °C, 850 °C, and 860 °C, each for 24 hours. The Tc-onset values increased with sintering temperature, reaching 50 K at 830 °C, 65 K at 840 °C, and 78 K at 850 °C. SEM images showed closely packed, flake-like grains around 2 μm in size, while XRD analysis confirmed that the sample sintered at 850 °C had the highest Bi-2212 phases as a major phase. Thus, this work outlines the practical steps of the thermal treatment approach and shows how adjusting the sintering temperature can significantly influence the superconducting performance and phase formation of Bi-2212

Abstract

Magnetic Resonance Imaging (MRI) systems generate intense static magnetic fields (SMFs), with fringe field propagation varying considerably between installations, even among scanners that operate at the same nominal field strength. This study investigates the safety implications of magnetic field leakage by quantifying and comparing SMFs distributions surrounding multiple MRI facilities. The assessment covers 1.5 T MRI scanners at Hospital Canselor Tuanku Muhriz (HCTM) and Hospital Pakar Kanak-Kanak UKM (HPKK), and 3 T scanners at the National Cancer Institute / Institut Kanser Negara (IKN), Pusat Pengimejan Diagnostik Nuklear (PPDN), and HCTM. Magnetic field intensities were recorded using a Magnetometer HP-01 provided by the Medical Radiation Surveillance Division (BKRP), Ministry of Health Malaysia, and visualised using MATLAB to model spatial field dispersion. Statistical tools, including Box and Whisker plots and the Shapiro-Wilk test, were employed to analyse magnetic field uniformity and containment. Specifically, 1.5 T scanners at HCTM and HPKK, and 3.0 T scanners at IKN, PPDN, and HCTM, each displayed distinct SMFs propagation profiles. These findings align with earlier studies conducted in Italy, confirming that magnetic field distributions near the magnet core can differ substantially based on scanner model and site-specific installation variables—even when B₀ remains constant. Notably, HCTM exhibited superior SMFs confinement, with lower standard deviation and a narrower distribution range, suggesting better shielding design. This enhances occupational safety in zones where radiographers frequently operate. The results reinforce the need for site-specific SMFs assessments and optimised shielding practices to maintain safe MRI environments for both staff and patients

Abstract

In this study, YBa2Cu3O7-δ (YBCO) superconductors were synthesized using a thermal treatment method with the addition of 1.0 wt. % SnO₂. The synthesis of YBCO employed nitrate-based precursors and polyvinylpyrrolidone (PVP) as a capping agent to enhance homogeneity during the synthesis process. All samples were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Four-point probe (4PP). TGA results of the pure YBCO sample confirmed the complete transformation of nitrate-based precursors into oxide forms prior to the formation of the YBCO phase. XRD pattern revealed that Y123 as a major phase and Y124 as a minor phase in all samples with orthorhombic crystal structure were preserved. However, the peak intensity of the Y123 was pronounced with the addition of the SnO2 sample, suggesting the enhancement phase formation due to the presence of SnO₂. The electrical resistivity measures revealed a sharp superconducting transition in all samples. However, the reduction in superconducting transition temperatures for the SnO2 addition were observed where the Tc-onset decreased from 91.70 K to 89.25 K for the YBCO and YBCO + 1.0 wt.% of SnO2, respectively. This also exhibited the broadening of transition width, ΔTc indicating the suppression of superconducting properties with SnO₂ inclusion. SEM analysis showed notable differences in microstructure. The pure YBCO sample exhibited a larger average grain size of 1.32 µm, while the YBCO + 1.0 wt. % SnO2 sample formed small and rounded grains with smoother edges, potentially impacting intergranular connectivity and charge transport. Therefore, the addition of 1.0 wt. % SnO2 to YBCO enhanced the formation of the Y123 phase but adversely affected the superconducting transition temperature and microstructural features. These findings highlight the dual role of SnO2 in promoting phase purity while modifying grain morphology and electrical performance, offering insight into the optimization of dopants in high-temperature superconductors

Basic materials used in the synthesis of BaCO3, FeCl3.6H2O and nickel metal. This study used a variation of calcination temperature of 80 ° C, 400 ° C, 600 ° C and 800 ° C for 4 hours with a variety of dopants 0; 0.4; 0.7 and 0.9. The results indicate that the formation of single phase and uniform distribution on M-barium hexaferrite (BaFe12-xNixO19) at 800 ° C calcination temperature and variations in dopant x = 0.7. The elements of barium is spread very evenly matched with the concentration of each element in the compound BaFe12-xNixO19. The addition of the dopant concentration can increase the value of conductivity that is in the range of 10-6 to 10-4 with a coercivity value at x = 0.7 and calcination temperature of 800 ° C at 0.05 T and magnetization value of 2.25 emu /g

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

Polymer-based radiation dosimeters have attracted significant attention in recent years due to their capability to measure complex radiation dose distributions in radiotherapy applications. This study aims to analyze the research trends related to polymer film and polymer gel dosimetry used in radiotherapy through a systematic literature review and bibliometric analysis. The study employed the PRISMA methodology to systematically identify and select relevant publications from the Scopus and SINTA databases. A total of 30 articles published between 2018 and 2025 were included in the analysis. Bibliometric analysis was conducted using VOSviewer to examine publication trends, keyword co-occurrence networks, and research collaboration patterns. The results indicate a steady increase in research publications related to polymer dosimetry over the past decade. Keyword clustering analysis revealed several dominant research themes, including polymer gel dosimetry, radiation polymerization, dose distribution measurement, polymer film dosimeters, and nanoparticle-enhanced polymer materials. Among these topics, polymer gel dosimetry remains the most widely studied due to its capability to record three-dimensional radiation dose distributions. However, recent studies have increasingly explored polymer film dosimeters and nanocomposite materials to improve radiation sensitivity and dosimetric performance. Overall, the findings highlight the rapid development of polymer dosimetry technologies and their growing importance in modern radiotherapy quality assurance. Future research should focus on developing advanced polymer nanocomposites and integrating imaging-based dosimetry techniques to improve radiation dose measurement accuracy and clinical applicability.

Abstract

High temperature superconductor of YBa2Cu3O7-δ (Y-123) has been synthesised using the modified thermal decomposition method (MTD). In this work, a pure Y-123 sample is produced using an acetate-based material as a precursor and sintered at 980 oC. The study on the phase formation, superconducting properties and microstructural characteristics of pure Y-123 was investigated using X-ray diffraction (XRD), four-point probe (4PP) and scanning electron microscopy (SEM) respectively. XRD analysis confirmed the formation of a single-phase orthorhombic Y-123 crystal structure with an orthorhombicity of 0.008, indicating high phase purity without detectable impurity phases. Electrical measurements revealed a sharp superconducting transition with a critical onset temperature, Tc-onset of 97.3. SEM observations showed plate-like grains with an average grain size of 2.25 µm and good grain connectivity. These results demonstrate that the modified thermal decomposition technique is an effective approach for producing phase-pure YBCO superconductors with excellent structural and superconducting properties, highlighting its potential for advanced superconducting applications
