The focus of this work is on the radiation security features of Novel Oxide Glass (PZBKTANEr). The unique glass assembly is 40P2O5-30ZnO- 20BaF2-3.8K2TeO3- 1.2Al2O3-5Nb2O5-3Er2O3 in mol percent (test code PZBKTANEr). For the suggested oxide glass, several radiation shielding characteristics have been investigated for a specific energy range of ionizing radiation. The linear and mass attenuation coefficients, mean free path, half-value layer, total nuclear and electronic cross-sections, and fast neutron expulsion cross-section are among the radiation shielding properties. Furthermore, the unique fabricated glass (PZBKTANEr) was compared to commonly used radiation protection compositions, such as RS-253 G18, RS-360, RS-520, Chromite, Ferrite, Magnetite, and Barite glass, as well as RS-253 G18, RS-360, RS-520, Chromite, Ferrite, Magnetite, and Barite glass. Also, we studied the structure of fabrication by using Raman spectra. The findings suggest that the new oxide glass might be used in a broad variety of ionizing radiation applications for protection in both therapeutic and industrial applications.","PeriodicalId":9710,"journal":{"name":"Chalcogenide Letters","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44866287","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 compound was prepared with a mixture of nickel acetate (C4H6O4Ni. 4H2O), cobalt chloride (CoCl2. 6H2O), and thiourea (CS(NH2)2) as precursors for Ni, Co, and S, respectively. The temperature and sedimentation time were 300 °C and 10 min, respectively; the film was then, characterized without any thermal post-treatment. The structural, morphological, optical and electrical analysis were carried out to investigate the different properties of the material. The X-ray diffraction analysis confirmed the presence of NiCo2S4 according to the JCPDS Card # 98- 004-0019, with an average crystallite size of 34.45 nm. The optical analysis revealed the metallic behavior of the film with an average transmittance of 3.41% in the visible region and a direct optical band gap of 2.15 eV, as well as a high absorption coefficient of α ≈ 104 - 105 cm-1 ). The elementary composition analysis (EDS) confirmed the presence of Ni, Co and S elements in the film. Morphological analysis revealed a homogeneous, compact, crack-free appearance and a granular surface in all studied areas. On the other hand, the film shows a high electrical conductivity of about 1.42×105 S/cm at room temperature. The obtained results show that the bimetallic (Ni, Co) sulfide prepared in this study exhibits a good crystallinity, dense morphology, good stoichiometric ratio and high conductivity. Therefore, it is a potential candidate for application in supercapacitors as electrode material.","PeriodicalId":9710,"journal":{"name":"Chalcogenide Letters","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67025004","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 effect of pH values of precursor solution on the crystal structural, morphological and humidity sensing properties of ZnO nanostructures have been investigated using different characterization technique.

The PXRD pattern clearly revealed the ZnO thin films have hexagonal wurtzite crystal structure. The average crystallite size of ZnO thin films have been calculated using Scherer formula and found to be ~24 nm to ~30 nm. The microstrain (ɛa) and (ɛc) of ZnO thin films for different pH values 8 and 11, have been calculated and found to be 7.59, 0.1017; 7.57, 0.1094 respectively.
