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.

Abstract

This study presents a comprehensive chemical, structural, and thermal characterization of polyethylene terephthalate (PET) flakes subjected to electron beam irradiation at doses of 0, 40, and 120 kGy. Post-consumer PET bottle flakes were analyzed using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Thermogravimetric Analysis (TGA) to determine irradiation-induced modifications. FTIR results reveal noticeable variations in key functional groups, particularly in the ester (C=O and C–O) and aromatic regions, indicating chain scission, partial cross-linking, and oxidation with increasing radiation doses. XRD analysis shows a progressive reduction in peak intensity and an increase in peak broadening, signifying decreased crystallinity and enhanced amorphous character due to structural disorder. TGA measurements demonstrate improved thermal stability of irradiated PET, with major degradation shifting from ~450 °C in the non-irradiated sample to ~480 °C after irradiation, and a clearer two-stage degradation pattern associated with structural rearrangements. These findings confirm that electron beam irradiation induces significant yet controlled modifications on PET’s molecular structure, crystallinity, and thermal behavior. Such property alterations highlight the potential of electron beam treatment as an effective pre-processing approach to enhance the recyclability and performance of waste PET, contributing to more sustainable plastic waste management strategies
