We found four emission peaks located at 562, 597, 644 and 706 nm corresponding to 4G5/2 → 6H5/2, 4G5/2 → 6H7/2, 4G5/2 → 6H9/2 and 4G5/2 → 6H1 1/2 transitions respectively. The emission and absorption spectra were analyzed using the Judd–Ofelt theory to calculate various spectroscopic parameters, such as emission cross-section, radiative transition probability, branching ratios, and stimulated emission cross-section.

The heating layer, which is a percolation network of carbon nanotubes (CNTs), is reinforced with a polymer to improve surface adhesion, strength, and wear resistance. Epoxy resin is used as a reinforcing polymer. Various methods of organizing a heating layer from CNTs with a reinforcing polymer are considered, and the best ones are identified for creating a heating or antistatic surface. The influence of the concentration of CNTs in the polymer on the strength of the composite is studied. Different methods of introducing nanotubes in the polymer are compared to achieve the best deagglomeration of nanoparticles. The effects of functionalization of nanotubes are tested, and an increase in the coating strength with a slight increase in conductivity is revealed. The optimal concentration of Taunit-M carbon nanoparticles for strengthening ED-20 epoxy resin is found to be 0.07% for nonfunctionalized nanotubes and 0.5–0.6% for particles with –CONH2 in groups. It is possible to achieve a superhydrophobic state of the surface: the contact angle of wetting is 152.3 ± 0.7 and the angle of the beginning of the sliding of the droplet is 1.6 ± 0.9.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"51 1","pages":"133 - 142"},"PeriodicalIF":0.6,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166123","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 sodium discharged from rejected sodium bonded metal fuel pins is blended with uranium and plutonium metals labelled as contaminated sodium. This contaminated sodium is converted to borosilicate glass with the addition of suitable glass formers and modifiers. Pristine borosilicate glass of known composition and doped glasses were prepared with fixed Na/Si ratio by addition of (i) U3O8 (5 wt %) and (ii) oxides of U, Ce, Nd, and Gd (together 5 wt %) labelled as BSGU and BSGURE respectively. Thermo-physical properties of these glasses are favourable towards safe disposal however, it is essential to evaluate aqueous alteration named as chemical durability (at 363 K) before using contaminated sodium. Surface morphology and chemical durability of pristine BSG were evaluated and compared with doped BSGs. The normalized leach rate for seven days was found to be 1.8 × 10–4, 5.5 × 10–5, and 4.2 × 10–5 g cm–2 day–1 for pristine BSG, BSGU, and BSGURE respectively.

X-ray diffraction investigation indicated the formation of face-centered cubic structure with the presence of nickel–tungsten phases. 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}

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.

It is established that the obtained ceramics have a predominantly ionic type of electrical conductivity (ion transport numbers ti = 0.78–0.96 in the range of 300–700°С). Electrical conductivity in solid solutions is realized by the vacancy mechanism and reaches the value of σ700°С = 0.43 × 10–2 S/cm.
