Elastic and mechanical parameters were evaluated using the Makishima–Mackenzie model to assess the influence of α‑Fe2O3 content on the glass system. The calculated bulk modulus reached 203.76 GPa at 1 mol % α-Fe2O3, while the estimated microhardness and fractional bond (dimensionless) connectivity attained maximum values of 16.39 GPa and 7.46, respectively. Radiation shielding performance was assessed using Monte Carlo N‑Particle (MCNP5) simulations over a photon energy range of 0.20–15.0 MeV, with results validated using the Phy-X/PSD platform. Among the studied compositions, the BWF1 sample (1 mol % α-Fe2O3) exhibited the highest shielding efficiency, achieving a maximum mass attenuation coefficient of 0.273 cm2/g at 0.2 MeV. Improvements in shielding parameters, including reduced mean free path and half-value layer, are associated with compositional changes and increased effective atomic number resulting from α-Fe2O3 addition. These results indicate that α-Fe2O3-containing borate glasses are promising candidates for radiation shielding applications in medical, environmental, and industrial fields, while further structural studies are required for detailed understanding and optimization.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"52 1","pages":"9 - 25"},"PeriodicalIF":0.7,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148357786","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}

In this study, a composition based on a styrene–butadiene thermoplastic elastomer with rheological properties that allow the fabrication of products on a 3D printer is investigated. The influence of the ratio between the components of a mixed nanocarbon filler, including graphene and carbon nanotubes, and the distribution of adsorption centers on their surface on the physical and mechanical characteristics of a thermoplastic elastomer (TPE) based on a styrene–butadiene elastomer is studied. The optimal ratio between graphene and nanotubes is determined to be 1 : 3, which provides the maximum increase in tensile and compressive strength due to the combination of the reinforcing action of one-dimensional nanotubes and the interaction of two-dimensional graphene layers with the polymer matrix. It is established that the strengthening of the resulting compounds is correlated with the content of the Brønsted basic centers (BBCs) on the filler surface, characteristic of graphene and presumably corresponding to peroxide groups that promote cross-linking of the polymer matrix.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 6","pages":"801 - 810"},"PeriodicalIF":0.6,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341729","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}

They efficiently rotate polarized light, making them essential for optical isolators and modulators requiring precise polarization control. We report the development of a novel Tb3+-doped La2O3–TiO2–Ga2O3–ZrO2 (LTGZ) glass system synthesized using the aerodynamic levitation melt-quenching (ALMQ) technique. This containerless, high-temperature processing ensures superior compositional homogeneity, phase control, and contamination-free synthesis which is essential for producing highly homogeneous, amorphous glasses with superior magneto optical quality. By systematically varying Tb2O3 concentrations (3–8 mol %), a maximum Verdet constant of 169.112 rad/(T m) at 650 nm was achieved, surpassing that of commercial terbium gallium garnet (TGG, ~125 rad/(T m)). Comprehensive structural, optical, and thermal analyses confirm the material’s amorphous nature, low phonon energy (~539 cm–1), excellent infrared transparency, and robust thermal stability (Tg = 886.2 °C). These attributes collectively position the LTGZ-Tb glass as a promising candidate for next-generation magneto-optical isolators, modulators, and integrated photonic circuits. This work highlights a new pathway for cost-effective, high-performance Faraday materials compatible with photonic miniaturization and device integration.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 6","pages":"811 - 819"},"PeriodicalIF":0.6,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341267","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}

The thickness and optical parameters of the coatings are determined by spectral ellipsometry, and the elemental composition is determined by scanning electron microscopy combined with energy-dispersive X-ray spectroscopy (SEM/EDS); and the morphology and continuity of the coatings are analyzed by atomic force microscopy (AFM). It is found that when the thickness of the titanium oxide layer is ≥24 nm, a single-phase, continuous titanium dioxide film is formed, completely covering the surface of the quartz substrate. It is shown that the rate of photodegradation of the dye reaches a plateau after the substrate is completely covered by the titanium oxide layer and remains virtually unchanged with a further increase in thickness. The obtained thickness–activity dependences set the minimum required thickness of TiO2 to achieve maximum photocatalytic efficiency under the given conditions and demonstrate the effectiveness of the ellipsometry, SEM/EDS, and AFM for monitoring the structure and continuity of ML-grown coatings.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 6","pages":"721 - 729"},"PeriodicalIF":0.6,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341617","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}
