This review aims to provide a comprehensive overview of the effects of ion substitution on the silica network of BG, focusing on silver (Ag), strontium (Sr), magnesium (Mg), lithium (Li), zinc (Zn), and copper (Cu). Through an extensive examination of recent literature, we investigated the primary effects of ion substitution on the glass structure, including change to its physical properties, impacts on pH and surface characteristics, and functional effects. The reports approved that ion substitution significantly alters fundamental parameters of the silica network, including thermal properties, porosity, swelling, and degradation. Each ion imparts distinct effects on the glass structure, bioactivity, and functional properties such as antibacterial activity, cell viability, osteogenesis, and angiogenesis. Notably, these effects are often dose-dependent and ion-specific. The review emphasizes that ion substitution is an effective strategy for producing high-quality BG with tailored properties. Understanding the specific effects of each ion facilitates the development of BG systems with controlled release and surface interactions, opening up new possibilities for various biomedical applications. This comprehensive overview provides valuable insights for researchers and practitioners in the field, paving the way for future advancements in BG design and application.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100598"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amongst various Mg alloys, AZ91 alloy has been trending and needs to be completely explored. The corrosion resistance of AZ91 alloy has always been a question, hence needs further investigation. The impact of face milling operations under cryogenic conditions on the corrosion properties of AZ91 alloy is studied in the current work. Using electrochemical polarization testing technique with a 3.5 % NaCl solution, the optimal surface finish of the alloy produced by cryogenic assisted face milling has been contrasted with dry milling. The polarization method compares both specimens after testing them for 0.5 h. Cryogenic machining considerably minimized the roughness by upto 28 % with values ranging between 0.0525 µm and 0.1169 µm when compared to the 0.1259 µm and 0.0691 µm from dry condition. The comparatively low roughness surface from cryogenic condition demonstrated a relatively low corrosion rate (1.1992 mm/year in cryogenic; 1.2891 mm/year in dry), indicating that the corrosion rates are directly related to the surface roughness. The superior corrosion resistance of the cryogenic milled surface over the dry milled surface was supported by the polarization curves. Additionally, the elemental analysis test on the surfaces after the polarization test revealed that the cryogenic milled surface had less oxygen (44.28 wt% and 7.29 wt%) than the dry milled surface (47.13 wt% and 10.01 wt%), proving the superior corrosion resistance of cryogenic milled surface.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100600"},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
