The photon interaction parameters such as mass attenuation coefficient, half and tenth value layer, mean free path, effective atomic number, buildup factors, and neutron interaction parameters such as fast neutron removal cross sections were estimated using Phy-X/PSD software. It is found that effective atomic number and equivalent atomic number values increase with an increase in GeO2 concentrations in the selected glasses, and mean free path values are lower than ordinary concrete and RS-253-G18. The effectiveness of shielding parameters such as buildup factors shows a broader distribution at lower mean free path and a narrower distribution at higher mean free path, peaking at 0.5 MeV of gamma energy. The neutron interaction parameters, such as fast neutron removal cross section values, decrease with an increase in the concentration of GeO2 in the selected glass. The mechanical parameters, such as the elastic moduli of selected glasses, show a decrease in value with an increase in mol % of GeO2. The relationship between elastic moduli and fast neutron removal cross section is observed for the first time.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 1","pages":"56 - 65"},"PeriodicalIF":0.6,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166651","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}

Microstructural analysis revealed that coatings were uniform and compact structure without any obvious defects. Cu–Ni–W thin films were thoroughly evaluated for their mechanical, structural, and corrosion resistance properties. Nanoindentation tests were carried out to calculate the mechanical properties, which include stiffness, elastic modulus, and nanohardness. The elastic modulus of 102 GPa and the hardness value of 5.4 GPa were obtained for the film deposited at –50 mA/cm2. Examination of the electrochemical Tafel plots indicated that the films deposited at higher current densities exhibited improved resistance to corrosion. The variation of Icorr values from 2.12 to 1.86 µA/cm2 implied that these films have a lower susceptibility to corrosion.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 1","pages":"66 - 72"},"PeriodicalIF":0.6,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165660","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}

A comprehensive analysis has been conducted to examine the electrical and dielectric properties over a broad spectrum of frequencies (102–106 Hz) and temperatures (303–573 K). According to the findings of conductivity studies, mixed conduction (both electronic and ionic) occurs in the produced glasses. As the concentration of Tl2O3 increases in the base glass, the dielectric properties, including dielectric loss, dielectric constant, and ac conduction, exhibit a decreasing trend. An increasing number of V5+ ions has been identified as being involved in the formation of networks near crystal structures of VO5. The quantitative study of ac conductivity and dielectric property data revealed that increasing the concentration of Tl2O3 in the glass network increases the insulating character of the glass. In the glass structure, the migration of thallium ions to tetrahedral coordination from octahedral coordination occurs, accompanied by a de-clustering effect of these ions.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 5","pages":"483 - 495"},"PeriodicalIF":0.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676397","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}

Especially tiles produced with digital applications attract much more attention. Digital glazes (glass-ceramic) can be matte or glossy features. In this study, the effect of the SiO2/Al2O3 ratio on technological properties was examined by keeping other oxide ratios constant in matte glaze compositions for digital applications. Seven glass ceramic compositions were prepared and trials were carried out under industrial conditions. The microstructure was measured with the use of a SEM, phases were determined by XRD, and sintering behavior was characterized by heating microscopy. The color and gloss of glazes were measured using a spectrophotometer and a gloss meter. As the SiO2/Al2O3 ratio decreased, especially the amount of anorthite crystal increased, which resulted in the formation of more matte glaze surfaces. Glaze whiteness and hardness increased due to the crystal formation. As the amount of Al2O3 increased, the softening and melting temperature points of the glazes also increased. It has been determined that surface properties can be modified for digital applications by changing the SiO2/Al2O3 ratio.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 6","pages":"639 - 646"},"PeriodicalIF":0.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676412","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}
