Molecular dynamics and density functional theory simulations were used to obtain the structural, electronic, and vibrational properties that contribute to electronic transport in a-SiOx. The percentage of Si-[Si1, O3] and Si-[Si3, O1], observed in a-SiO1.3, decrease with increasing O ratio. Vibrations in a-SiOx showed peaks that result from topological defects. The electronic conduction path in a-SiOx favored Si-rich regions and Si atoms with dangling bonds formed charge-trapping sites. For doped a-SiOx, the type of doping results in new conduction paths, hence qualifying a-SiOx as a viable candidate for PUF fabrication as reported by Kozicki [Patent-Publication-No.: US2021/0175185A1, 2021].</div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"18 ","pages":"Article 100179"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46895491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the dissolution experiments in water, the pH of the solution at the conclusion of the experiments increased systematically, from 2.1 to 9.5, for y = 0 glasses when ‘x’ increased from 0 to 60. The reaction rates over the first 8–24 h of dissolution in both SBF and deionized water followed linear kinetics, with reaction rates dependent on glass composition. For glass particles in SBF, replacing P2O5 with up to 20 mol% B2O3 decreased the dissolution rate (fraction dissolved) by two orders of magnitude, from 7.0 × 10−3 h−1 for x = 0 to 2.0 × 10−5 h−1 for x = 20. Further replacement of P2O5 by B2O3 increased dissolution rates by three orders of magnitude, to 2.3 × 10−2 h−1 at x = 60. The compositional dependence of the dissolution rates is explained by changes in the glass structure, with the most durable glasses possessing the greatest fraction of tetrahedral borophosphate sites in the glass network. Crystalline brushite was detected on Ca-glasses with 35 and 40 mol% B2O3, but the dominant precipitation phase on both the Ca- and Sr-glasses is an x-ray amorphous material constituted from orthophosphate and pyrophosphate anions.</div>","PeriodicalId":37132,"journal":{"name":"Journal of Non-Crystalline Solids: X","volume":"18 ","pages":"Article 100181"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41321287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
