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

Abstract

The application of polymer dose gels is limited by the sensitivity of dose readout methods and dose gel properties. It is a challenge to find suitable dosimeters for registration of doses delivered to the target by orthovoltage therapy units. The application of metal-particle-enriched polymer composites for dose registration in X-ray therapy might be an elegant solution, especially if recent dose-reading technologies exploring advantages of different physical phenomena are involved.

Abstract

This work investigates the formulation of a radiation-curable coating that integrates functionalized carbon nanotubes (f-CNT) to improve surface characteristics. Trimethylolpropane triacrylate (TMPTA) was employed as the monomer, with epoxy acrylate and urethane acrylate as oligomers and Irgacure-500 as the photoinitiator. To cure the coatings, the formulations were subjected to ultraviolet (UV) light, and the surface properties were investigated using Fourier-transform infrared spectroscopy (FTIR), pendulum hardness testing, and thermogravimetric analysis (TGA). The results show that altering the ratios of f-CNT in the formulations have a considerable impact on the mechanical and thermal characteristics of the coating. The findings show that ideal compositions of these additives improve the hardness, crosslinking density, and thermal stability of the cured films, offering insight into their potential

Abstract

Colossal magnetoresistance (CMR) materials are widely studied to be applied in magnetic sensing elements. The incorporation of a secondary oxide phase into manganites has been explored to improve low-field magnetoresistance (LFMR). In this study, polycrystalline Nd0.67Sr0.33MnO3 (NSMO) was synthesised via the sol-gel method, and different contents of CuO nanopowder were added to form (1–x) NSMO: x CuO composites. The structural, magnetic, and electrical properties of the composites were characterised by X-ray diffraction (XRD), AC susceptibility (ACS), and Hall effect measurement (HMS). XRD results confirmed the orthorhombic structure in all samples and indicated no reaction between NSMO and CuO, suggesting that CuO segregates at the grain boundaries or surfaces of NSMO grains. Magnetic measurements revealed negligible variation in the Curie temperature (TC), while electrical measurements showed a suppression of the metal–insulator transition temperature (TMI). Although LFMR was more pronounced at lower temperatures, no enhancement was observed in the NSMO composites compared to its parent compound. This behaviour is attributed to spin-polarised tunnelling, which dominates LFMR and is primarily dominated by the nanoscale NSMO achieved through sol-gel synthesis. These findings offer valuable insights into the magnetotransport properties of NSMO:CuO composites and the role of secondary oxide phases in tailoring LFMR.

Abstract

This research focuses on development of local Timor lurik peanut through breeding using multigamma irradiation method, careful selection, and purification to obtain superior generation. The advantage of method is that superior generations are obtained in a relatively short time. Development using modern technology needs to be carried out considering that the production of lurik peanuts at the farmer level has only reached 0.7 t ha-1 to 1.2 t ha-1. The objective of the research is to develop local Timor lurik peanut through breeding using multigamma irradiation method, careful selection, and purification to obtain superior generation seeds. The main research methods are observation, irradiation, careful selection, purification, analysis, and interpretation. Brief procedure of the research: observation for selection of local lurik peanut seeds and identifying the chemical and physical characteristics of parent as comparative materials, preparing the land, cultivating the land, irradiating the seeds, planting on the prepared land, weeding to be free of weeds and fertilizing, irrigating as needed, spraying insecticides as needed, observing and measuring during growth, harvesting, and sorting superior generation seeds. The results obtained: development of local Timor lurrik peanuts through breeding with multigamma irradiation and careful selection obtained superior selected generations that adapt to drought conditions, tolerant of pests and diseases, and high production. The production range of the superior generation resulting from multigamma irradiation was (4.56-4.75) t ha-1 with an average production of 4.63 t ha-1. The percentage increase in production of the superior selected generation was 41.04%, an average water content was 11.2%.

Abstract

In this work, (Bi, Pb)-2223 superconducting ceramics with the nominal composition Bi1.6Pb0.4Sr2Ca2Cu3O10 were synthesised via the co-precipitation method and sintered at temperatures of 845 °C, 850 °C, and 855 °C. X-ray diffraction (XRD) analysis confirmed the dominance of Bi1.6Pb0.4Sr2Ca2Cu3O10 phase with minor traces of secondary phases, Ca2PbO4 (dicalcium lead (IV) oxide). An increase in sintering temperature led to a larger average grain size and reduced intergranular voids. Electrical resistivity measurements using the four-point probe method revealed the highest superconducting transition temperature (Tc onset = 104 K) for samples sintered at 845 °C. Higher sintering temperatures reduced the value of Tc onset and resulted in a wider transition width, ΔTc. These findings highlight the critical influence of sintering temperature on the structural and microstructural properties, which in turn govern the superconducting performance of (Bi, Pb)-2223 ceramics.
