As an alternative method of treatment delivery, the localized drug delivery systems have come up promising with controlled release, lesser side effects and better therapeutic results. Hydroxyapatite (HAp), which is a calcium phosphate mineral that occurs naturally and demonstrates high biocompatibility as well as osteoconductivity, has attracted a lot of interest in bone tissue engineering and specific drug delivery. Nevertheless, there are inherent shortcomings of it such as brittle and low drug loading capacity (typically 2–10 wt%), which demand functionalization strategies.

The correlation between experimental data and quantum descriptors establishes electron-donating capability and molecular reactivity as key factors governing adsorption strength. Overall, the combined experimental and theoretical results highlight sorbitol and sodium salicylate as promising corrosion inhibitors for magnesium, contributing valuable understanding toward the development of Mg-based systems for energy and structural applications. However, sorbitol emerged with the highest inhibition efficiency (IE) and Utilization Efficiency (UE) suggesting that there may exist a relation between utilization efficiency and inhibition efficiency depending on molecular structure and electronic properties of the compound.</div></div>","PeriodicalId":100614,"journal":{"name":"Hybrid Advances","volume":"12 ","pages":"Article 100597"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924320","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}
