For acetate complexes of Mn(II) with 1,10-phenanthroline, their fungistatic activity in relation to Ulocladium sp. fungi is studied. The physical and mechanical properties of new transparent protective coatings on wood, which contain these compounds as active biocidal components, are studied. The transparent protective coatings are two-layer systems with a primary impregnation layer of an active biocidal component—acetate 1,10-phenanthroline complexes of Mn(II)— applied to the wood surface, followed by a second protective layer of organosilicon varnish KO-921 based on polymethylphenylsiloxane resin. The results of atmospheric weather tests of wood samples (pine sapwood) with the applied transparent protective coatings are presented in terms of their ability to prevent biodegradation of wood in the conditions of the tropical savanna climate of the Joint Russian–Vietnamese Tropical Research and Technology Center (Russian–Vietnamese Tropical Center).","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 4","pages":"423 - 435"},"PeriodicalIF":0.6,"publicationDate":"2025-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145500750","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 thermal stability of Dy2SrAl2O7 up to the temperature of incongruent melting at 1750°С is characterized for the first time. The coefficient of thermal expansion (CTE) of Dy2SrAl2O7 is experimentally determined to be 8 × 10–6 K–1 in the temperature range of 400–1300°С. It is shown that active sintering of Dy2SrAl2O7 begins at 1300°С. A change in the type of melting diagrams is shown in the Ln2SrAl2O7 series, where Ln = La → Gd → Dy, Ho.

The challenge lies in achieving a balance between the structural performance of concrete and the economic and environmental advantages of utilizing recycled materials. To address this issue, river sand was partially replaced with WGS at varying proportions (0–60 wt %), and the resulting waste glass sand concrete (WGSC) was assessed for workability (slump), mechanical properties (compressive strength and elastic modulus), and economic viability (functional, cost, and value coefficients). The findings indicated that higher WGS replacement rates enhanced flowability while maintaining a stable elastic modulus. Compressive strength, measured in both cubic and prismatic forms, initially increased before declining at higher replacement levels. The functional coefficient increased initially but then decreased, whereas the cost coefficient consistently decreased. The value coefficient displayed a nonlinear trend, initially increasing, then decreasing, and subsequently rising again. A linear regression model revealed a strong correlation between the value coefficient and the WGS replacement rate. Importantly, WGS not only reduced material costs but also mitigated functional deficiencies, demonstrating its potential as a sustainable partial substitute for river sand in concrete.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 3","pages":"255 - 265"},"PeriodicalIF":0.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122369","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}
