3D printing technology can fabricate three-dimensional objects based on layers and is applied across various fields such as biotechnology, medicine, industry, education, and space, etc. This study aimed to produce a scintillator resin capable of detecting radiation using commercial resins for DLP 3D printers. The commercial resin used was a transparent acrylic resin (Acryl Resin Pro, Anycubic...

Lithium borate glass and Dysprosium (Dy³⁺) ions are well-suited for radiation dosimetry due to their atomic numbers, which closely resemble that of human tissue, and the superior light emission properties of Dy³⁺ ions. Lithium borate glass with a composition (mol%) of (50-X)li2CO3: 50B203: XDy2O3 where X is 0.1%, 0.5% and 1% were prepared by conventional melt quenched technique. Properties...

Proton beam (PB) therapy is gaining popularity for breast cancer treatment because of its enhanced coverage and potential to minimize late toxicities. The dose and volume of PB irradiation are closely associated with improved breast cancer survival. We aimed to investigate the impact of PB irradiation on the survival of the human breast cancer cells MCF-7 and their resistance to...

Proton beam therapy has recently been used to improve local control of tumor growth and reduce side effects by decreasing the global dose to normal tissue. However, the regulatory mechanisms underlying the physiological role of proton beam radiation are not well understood, and many studies are still being conducted regarding these mechanisms. To determine the effects of proton beams on...

The impact of proton irradiation on the metal-insulator transition (MIT) of Vanadium dioxide (VO₂) was investigated through in-situ X-ray absorption fine structure (XAFS) and electrical resistance measurements. VO₂ films, approximately 100 nm thick, were fabricated using DC-sputtering deposition techniques. Protons with energies of 100 and 200 keV and fluxes of 10^14 and 10^16 protons/cm² were...

Magnesium diboride (MgB$_2$) is a conventional superconductor that has high critical temperature (T$_c$ ~ 39 K) and current density (J$_c$), making it a promising candidate for various applications [1]. Ion irradiation on MgB$_2$ thin films induces disorder through atomic lattice displacement, which reduces T$_c$ [2,3]. In this study, we investigated the influence of He ion irradiation...

In our previous study, we showed that CeFe12 thin films exhibit enhanced magnetism when implanted with nitrogen ion beam. Since this nitridated CeFe12 can be a candidate for next-generation permanent magnets, it is necessary to test thermal stability of the nitridated CeFe12. In this presentation, we performed vacuum annealing on the same ion implanted CeFe12 thin films at 300℃, 500℃, and...
