The efficiency of SG-SDP to capture uranyl ions was evaluated using a variety of factors, including temperature (T), pH, contact time (t), and initial concentration (Ci). Under particular conditions (pH = 2, Ci = 1.0 mg L−1, T = 55 °C, 80 rpm, and dosage = 2 g L−1), sorption equilibrium is reached in 40 min, resulting in the greatest elimination percentage of 90%.

All the simulations are made considering a thermalised Am-Be neutron source. The simulations are validated, qualitatively and quantitatively, by comparing the simulated energy spectra and sensitivity values with those obtained from experimental measurements carried out using two different thicknesses of the crystal from our own experiment (0.5 mm and 3 mm) and validated with three other thicknesses (0.01 mm, 0.1 mm and 1 mm) from literature (Taggart et al. in IEEE Trans Nucl Sci 67:603–608, 2020). In this study, we define sensitivity of GAGG:Ce as the ratio of area under 77 keV sum peak to 45 keV peak. The present studies clearly confirm that, while it requires about 0.1 mm thickness for the GAGG:Ce crystal to fully absorb thermal neutrons, it requires about 3 mm to fully absorb the thermal neutron induced events. Further, we propose an equation, that can be used to estimate the thickness of the GAGG:Ce crystal directly from the observed sensitivity of the GAGG:Ce crystal. This equation could be very useful for the neutron imaging community for medical and space applications, as well as for manufactures of cameras meant for nuclear security purposes.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 3","pages":"2203 - 2210"},"PeriodicalIF":1.5,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10967-024-09976-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phase evolution, microstructure, density, and chemical stability of the sintered samples were systematically researched.

Both cell types were exposed to 6 MV X-ray radiation (0–5 Gy). Non-radiated bystander cells were co-cultured with irradiated cells using a transwell system to assess radiation-induced bystander effects. Cell survival was measured by clonogenic assays, and apoptosis, mitotic catastrophe, and senescence were evaluated morphologically. The results showed that bystander and directly irradiated MCF-7 and MCF-10A cells exhibited reduced survival, with a more pronounced effect in irradiated cells. Apoptosis was the dominant cell death pathway in both conditions, with MCF-7 bystander cells exhibiting an earlier onset than MCF-10A cells. Apoptosis rates exceeded 23% at doses above 4 Gy. Mitotic catastrophe was more common at higher doses, with MCF-7 bystander cells responding at 4 Gy and MCF-10A irradiated cells at 4.5 Gy. Senescence was primarily observed in bystander cells, with higher levels in MCF-7 and MCF-10A bystander cells compared to irradiated cells. These findings indicate that while apoptosis and mitotic death are prevalent in directly irradiated cells, bystander cells predominantly experience apoptosis and senescence. The differential responses between cancerous and normal cells highlight the potential for optimizing radiation therapy to target cancer cells more effectively while preserving healthy tissue.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 3","pages":"2291 - 2303"},"PeriodicalIF":1.5,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10967-025-09980-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
