HNT was added to the structure as a SiO<sub>2</sub> source to the MgO ceramics, which are difficult to process, since SiO<sub>2</sub> suppresses the grain growth of MgO ceramics and significantly reduces the sintering temperature. After calcination at 800 °C HNT at different ratios (1, 3, 5, 7, 9, 11 wt%) were added to calcined MgO powder. As a result of XRD analysis, it was determined that spinel, forsterite and periclase phases were formed and these results were also confirmed by SEM images. The addition of HNT led to the formation of the forsterite phase at grain boundaries, enhancing mechanical properties. The best mechanical properties were observed in MgO ceramics with 11% HNT additives. Adding HNT at different ratios increased the dielectric constant of MgO ceramics. HNT-added MgO ceramics exhibited higher dielectric constant value than those at ambient temperature. The lowest dielectric constant value was measured as ~ 8.5 for MgO ceramic without any HNT addition. Since the materials to be used as circuit substrates require strict dielectric and mechanical properties, it is aimed to improve the mechanical and dielectric properties of MgO ceramics with the addition of HNT. MgO ceramics incorporating HNT in this study exhibited outstanding dielectric and mechanical characteristics, suggesting their potential as favorable materials for circuit substrates.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 2","pages":"431 - 441"},"PeriodicalIF":1.8,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s41779-024-01145-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MHAP ceramic was prepared by wet precipitation method. The MHAP/BSA/CAE composite coatings were developed on the titanium (Ti) surface with the use of dip coating method. The coatings were characterized by FT-IR, XRD, SEM, and TEM techniques. SEM with EDX and HR-TEM techniques provided the morphological data and bio-activity nature of the prepared coatings from micro to nano scale levels. The in-vitro results indicate that the addition of CAE has increased the osteoblast cell viability along with increased anti-bacterial activities against gram-negative <i>E. coli</i> and gram-positive <i>Staphylococcus</i> strains. Meanwhile MHAP/BSA/CAE coatings at high concentrations was toxic to osteoblasts cell viability. But it clearly inhibited the bacterial growth.

An effective and creative method for synthesizing a composite of water hyacinth fiber with nickel ferrite and PANI is proposed in this study. The synthesis is carried out via in-situ chemical oxidative polymerization using freshly prepared lime juice as green media. The structural characterizations of the prepared composites are carried out using XRD and FTIR analysis and the formation of the composite is confirmed. Morphological studies are done by SEM and elemental detection by SEM mapping. The thermal stability of the composites is studied by TGA. By analysing DC conductivity, AC conductivity and dielectric characteristics, the performance of the synthesized samples is comprehended. The ternary composite exhibits excellent conductivity in 10<sup>− 3</sup> Scm<sup>− 1</sup> range. The polaron/bi-polaron interaction paradigm can be used to explain the superior conductivity performance of the ternary composite. Using a vector network analyser, experiments on electromagnetic interference (EMI) shielding are carried out in the frequency range of 8.2 to 12.4 GHz. The material exhibits an outstanding shielding response showing 20 dB for fiber-ferrite binary composite and 26.6 dB for fiber-ferrite-PANI ternary composite. It is analysed that, the composites are easy to develop, more stable and less hazardous to the environment, and can be used as useful shielding materials.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div><div><p>The graphical representation explains the formation of binary and ternary composites and their applications</p></div></div></figure></div></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 2","pages":"581 - 601"},"PeriodicalIF":1.8,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892738","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}
