The best results for β-TCP were achieved after sintering at 1200oC and with an average grain size of 5.077 ± 0.571 µ. However, sintering at 1250oC caused a 45% increase in the grain size of β-TCP, micro cracking and decomposition of 3.2% into alpha tricalcium phosphate (α-TCP) resulting in a decrease in its properties. Depending on the BaTiO3 ratio, 9 different phases with general chemical compositions of Bax/Cay-Tim-On, as well as α-TCP, were detected in the composites. As the sintering temperature and BaTiO3 ratio increased, the α-TCP ratio in the composites increased to 49.7%. The highest mechanical performances in composites were achieved at the sintering temperature of 1200oC and with the addition of 3wt%-BaTiO3. In vitro studies showed that the surface of this composite was completely covered with apatite on the 28th day.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"29 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177457","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}

This research focuses on boosting the energy storage capabilities of BaTiO3 ceramics through Mg2+ doping. Introducing Mg2+ ions into the BaTiO3 lattice induces defects and grain boundary effects, significantly influencing ferroelectric properties. Rietveld refinements of X-ray diffraction confirmed that both pure and Mg-doped samples show the same tetragonal phase. SEM analysis revealed a refined grain microstructure in the Mg2+ doped BT sample, which resulted in improved thermal stability and pinched ferroelectric hysteresis loops. Incorporating Mg2+ ions into the BT host lattice significantly enhanced energy storage density from 0.204 J/cm3 to 1.42 J/cm3 and efficiency rising from 21 to 89%. This enhancement is attributed to defect dipole engineering and the attainment of fine grain size. Furthermore, an examination of the electronic structure, overall density of states (DOS), and electronic density of both samples is undertaken. The defect dipole mechanism proposed in this study introduces a novel and promising strategy for developing high-performance energy storage in ferroelectric ceramics, holding great promise for next-generation applications.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"60 5","pages":"1709 - 1721"},"PeriodicalIF":1.8,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177455","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}

To study the effect of Li+ ions, different amounts of LiCl were used within the synthesis of BaAl2O4-based compounds. The crystal structural, microstructure, surface characteristics, and photoluminescence properties were scrutinized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), photoluminescence (PL), Fourier transform infrared (FTIR) analyses. It was shown that the addition of LiCl flux material results in very slight changes in the crystallographic properties of BaAl2O4 crystal structure while the use of LiCl has severely reduced the average particle size from about 225 nm to 120 nm. Upon the excitation procedure at the wavelength of 343 nm, BaAl2O4: Eu2+ shows a strong and wide emission in the range of 435–610 nm that is attributed to the 4f65d1-4f7 transition of Eu2+. The highest emission occurs when 2.5 wt% LiCl was utilized as flux material. Moreover, through the employment of XPS characterization, it was proved that the addition of Li+ ions causes higher binding energies of elements and improvement of crystallization.","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"132 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177458","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}

To obtain a great effect of intrinsic activity and the exposure of interfacial active sites at a greater density is often recommended when designing active and effective catalysts for OER via water splitting to attain clean energy in the form of hydrogen. In present work, cobalt ferrite (CoFe2O4) and polyaniline (PANI) are combined to design cluster-based catalysts with robust efficiency. The CoFe2O4 nanoflakes in this instance are uniformly adorned with PANI to provide an electronic effect on the CoFe2O4 nanoflakes. Thus, the designed interface needs an overpotential of 151 mV for OER, which is steady for up to 80 h of testing. The exceptional activity and longstanding durability are a result of the higher revelation of active sites, and faster kinetic reactions. Furthermore, the resultant material shows a small 105 mV/dec Tafel slope, offering the outstanding performance. Hence, this work proposes a novel method for designing nanostructures and for quickly producing oxide heterostructures based on transition metals, which are useful for future electrochemical applications.<h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"16 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177461","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}

Notably, significant attention has been directed towards hydroxyapatite (HA)-reinforced composites, particularly for bone tissue engineering applications, leveraging HA’s chemical resemblance to native mineralized tissue components. This review delves into the utilization of AM techniques for processing HA-reinforced composites and biocomposites to fabricate scaffolds embedded with biological matrices, including cellular tissues.
