Moreover, zeta potential values for pCQDs (+15.7 mV) and cCQDs (−54.9 mV) indicated a significant difference in surface charge. Despite the higher colloidal stability and superior optical properties of cCQDs (QY = 8.3 %), pCQDs demonstrated stronger antibacterial activity, particularly against <em>Staphylococcus aureus</em>. pCQDs also showed greater free radical scavenging activity than Trolox. Both types of CQDs exhibited low cytotoxicity toward fibroblast cells and did not cause significant hemolytic effects in human red blood cells.

In this study, citric acid was employed as a multifunctional stabilizing and chelating agent in the ultrasonic-assisted synthesis of HAp@Fe<sub>3</sub>O<sub>4</sub> nanohybrids. Systematic variation of citric acid concentration (0.2–0.8 wt%) revealed its critical role in interfacial binding, electrostatic stabilization, and dispersion control.

The radiation shielding properties were investigated from 0.015 to 15 MeV. The BaE4 sample has the highest linear attenuation coefficient (LAC) and effective atomic number (Z<sub>eff</sub>). The maximum Z<sub>eff</sub> is found at 0.015 MeV, ranging from 41.54 to 43.85. The BaE4 sample possesses the lowest MFP at all selected energy levels. The comparison with other glass systems confirms the suitability of the BaE4 sample for gamma ray shielding applications.</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"10 4","pages":"Article 101011"},"PeriodicalIF":6.8,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
