The experimental MAC values, obtained using a ¹³⁷Cs source (4.5 µCi, 662 keV) were compared with theoretical values from XCOM software, showing close agreement. Results indicate that the sample with the highest Bi₂O₃ content, exhibited the highest MAC and the lowest HVL (1.477 cm at 662 keV), making it the most effective radiation shield. Density decreased with increasing MnO₂, while molar volume and non-bridging oxygen content increased, influencing band gap reduction from 3.49 to 3.27 eV. The refractive index and cationic polarizability increased with MnO₂ concentration, affecting structural rigidity. Poisson’s ratio analysis indicated higher cross-link density in MnO₂-rich samples (S4–S6), leading to a more rigid network. Compared to barite concrete, prepared samples demonstrated superior radiation shielding, making them promising candidates for gamma-ray attenuation applications.</p>","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 6","pages":"790 - 800"},"PeriodicalIF":0.6,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using density functional theory, we carry out calculations to thoroughly study this material. It is found that TiS₃ is the most suitable material for cathodes of Ca-ion batteries. Intercalation of Ca²⁺ cations in TiS₃-based cathode materials turned out to be energetically favorable, with an operating voltage of 1.98 V relative to Ca/Ca²⁺. This result is noteworthy because high-voltage electrodes for multivalent batteries are relatively rare. Diffusion coefficients of Mg²⁺ and Ca²⁺ amounted to 6.59 × 10^–13 and 4.03 × 10^–21 cm² s^–1, respectively. The diffusion coefficient can be further improved by lattice strain engineering and the use of two-dimensional materials.
