This work aims to study the effect of Na2SiO3 on the characteristics of foam glass made from soda-lime waste glass using CaCO3 as a foaming agent. Foam glass samples were prepared by sintering at a temperature of 850°C for 10 min with a heating rate of 6.5°C/min. The first sample contains 99 wt % waste glass powder and 1 wt % CaCO3, and the other samples were developed by replacing a quantity of glass powder with 10, 20, 30 and 40 wt % of Na2SiO3. The effect of this substitution on the properties of foam glass was studied using a scanning electron microscope (SEM), a differential thermal analysis (DTA), a thermal gravimetric analysis (TGA), Fourier-transform infrared analysis (FTIR), thermal insulation and mechanical strength tests. Experimental results showed that the addition of Na2SiO3 increases the porosity of foam glass giving it a very low thermal conductivity (0.026 Wm–1 K–1) by thus increasing its power of thermal insulation.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 5","pages":"476 - 482"},"PeriodicalIF":0.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676396","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}

This is confirmed by the study of the phase composition of the synthesized phosphors and changes in the radioluminescence spectra. The observed result is proposed to be explained using the concepts of percolation theory, taking into account that the formation of a luminophore matrix of a composite wurtzite–sphalerite composition promotes an increase in the diffusion rate of the activator and coactivator ions (Cu+ and Br–) along the interphase boundary and the formation of glow centers. It is shown that radiation exposure, which promotes the formation of structural defects in the initial ZnS matrix, additionally increases the luminescence intensity.

However, the poor mechanical properties and high temperature instability of pure silica aerogels seriously restrict the development and application of silica aerogels. Fiber reinforcement is an effective way to improve the mechanical properties of silica aerogels. In this paper, Al2O3–SiO2 aerogel was compounded with mullite fiber to prepare silicon–aluminum aerogel fiber felt. When the strain value reaches 30%, the compressive strength of the fiber felt with aerogel content of 50.1 wt % reaches 0.21 MPa, and the thermal conductivity of fiber felt decreases from 0.0425 to 0.0322 W/m K when the aerogel content increases to 50.1 wt %. The thermal insulation performance test of fiber felt also showed that the addition of aerogel could significantly improve the heat insulation of fiber felt, and the cold surface temperature of fiber felt was only about 33°C when the flame exceeding 1000°C calcined the fiber felt for 10 s. This work provides a simple solution to prepare aerogel/nanofiber felt with good mechanical properties and low thermal insulation. Highlights: silicon–aluminum composite aerogel felt (AS/ASNFAs) has been prepared by sol-gel and impregnation method, AS/ASNFAs has good mechanical properties (the compressive strength reaches 0.21 MPa) and thermal insulation (0.0322 W/m K), AS/ASNFAs has good flame retardancy, and it remains stable after being burned at 1000 degrees butane for 10 min.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 5","pages":"511 - 520"},"PeriodicalIF":0.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676398","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 protection of material surfaces from destruction by micromycetes-destructors is of particular interest. The study presents data on the interaction of nanomaterials of the Taunit-M brand (multiwalled carbon nanotubes), onion-shaped carbon nanostructures, and Tuball (single-walled carbon nanotubes) with micromycetes-destructors. The aim of this paper is to study the influence of these materials used in the coating composition on the processes of surface overgrowth by micromycetes-destructors. The growth of the Penicillium chrysogenum strain (Cs/21) and Aspergillus niger strain (Ch4/07) on pure carbon nanotubes, nanotubes functionalized with –OH, –COOH, and –CONH2 groups, as well as carbon nanotubes decorated with onion-shaped carbon nanostructures, detonation nanodiamonds (DNDs), and titanium dioxide nanocrystals, is studied. The samples are made in the form of a superhydrophobic coating of nanoparticle-based xerogel. The highest resistance is demonstrated by coatings made of functionalized multiwalled carbon nanotubes of the Taunit-M brand with –OH, –COOH and CONH2 groups, as well as those decorated with titanium dioxide and DNDs. The development of micromycetes on their surface is absent in all test variants. These coatings do not contain food sources for micromycetes, but contain components with biocidal properties. Thus, they can be considered biostable. The studied carbon nanomaterials are proposed to be used for the organization of protective superhydrophobic coatings, since they are produced in industrial quantities and are easily accessible for comparative studies.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 6","pages":"705 - 712"},"PeriodicalIF":0.8,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676280","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}
