In contrast, the carnivorous <i>Esox lucius</i> (El) (northern pike) inhabits rivers, lakes, and brackish waters across the Northern Hemisphere. Utilizing these species as biomaterials can supports waste management and biocompatible material synthesis. In this study, the morphological and chemical characteristics of calcined fish bone powders from different anatomical parts, including head bone (HEB), otolith bone (OTB), operculum bone (OPB), and spine bone (SPB), were systematically investigated. The particle size distribution analysis revealed that Cg-HEB exhibited the smallest particle size (53.91 μm), whereas El-OTB had the largest (431.54 μm). Morphological analysis confirmed a predominant rod-shaped structure for both Cg and El samples, except for El-OTB, which exhibited a distinct morphology. X-ray diffraction (XRD) analysis confirmed hydroxyapatite (HA) as the primary crystalline phase in all samples, accompanied by the presence of β-tricalcium phosphate (β-TCP). Fourier transform infrared (FTIR) spectroscopy further validated the presence of phosphate (PO₄³⁻) bands at 1030–1100 cm⁻¹ and 560–600 cm⁻¹, reinforcing HA as the dominant phase. The Ca/P ratio analysis indicated that Cg-SPB had a slightly lower ratio (0.07 less) than the stoichiometric Ca/P ratio of human bone, suggesting an increased β-TCP content.

Commonly used alumina fibre reinforced composites, though exhibit high fracture toughness, show limitation for use at high temperatures, due to structural transformation and recrystallization of the fibres, and for net-shaping into intricate geometries. Present work addresses these constraints by choosing α-alumina platelets of approximately 150 ± 25 nm thickness as reinforcement, and gelcasting process for shape-forming the composites. A free-flowing ceramic slurry having uniform distribution of monazite (LaPO<sub>4</sub>)-coated platelets was cast and gelled in disposable expanded polystyrene (EPS) molds that are machined as per the computer aided design (CAD). The green bodies are dried, debindered and sintered to obtain compacts of alumina composites with different amounts of platelet alumina (0 to 25 wt%) and are characterized. Compared to monolithic alumina, a notable enhancement (by 80%) to 5.4 MPa<span>(:surd:m)</span> in fracture toughness was observed, while maintaining a flexural strength of 310 MPa, in the composite with 4 wt% platelet content. Microstructural studies reveal deflection, bridging, and branching of the cracks caused by the coated platelets and provide evidence for their contribution to improved fracture toughness. The optimized composites have the potential for use in biomedical sector. They are particularly suitable for high-temperature applications, furthermore, α-alumina platelets possess superior thermal stability at elevated temperatures compared to alumina fibres and exhibit excellent oxidation resistance, unlike carbon fibres. These attributes ensure their structural integrity under extreme conditions, making them highly effective as reinforcements for high-temperature applications where both mechanical performance and environmental durability are critical. The present process is inexpensive and enables manufacturing of complex geometries, making it attractive for adoption by industries.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 5","pages":"1799 - 1810"},"PeriodicalIF":2.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145646168","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}

Data-driven approaches are increasingly popular in materials science. However, these methods heavily rely on dataset size. To tackle this, we propose a two-step data enhancement method using Auxiliary Enhanced-Least Squares Generative Adversarial Networks—Tree-structured Parzen Estimator—Multilayer Perceptron (AE-LSGAN-TPE-MLP). The method improves model stability and data quality by adding auxiliary generator and discriminator networks that operate alongside the primary ones in the LSGAN framework. Additionally, data enhancement occurs in two steps to further ensure data quality. In the first step, feature enhancement is performed using a label-guided feature separation strategy. Features corresponding to different label categories are separated, and the AE-LSGAN model is trained independently for each category to generate realistic feature data. In the second step, pseudo-labels for augmented features are predicted. An MLP model is pre-trained on 50% of the dataset, and the generated features are used as input to predict pseudo-labels. Finally, the augmented dataset is merged with the training set, and a TPE-MLP model is built for prediction. Comparative results show that the proposed method significantly improves model performance, achieving 0.9629 accuracy on a test set comprising 50% of the dataset. Moreover, three HECCs were synthesized through experiments, further validating the model's accuracy. Finally, an interpretability analysis of the model was performed, with the shapley additive explanations (SHAP) summary plot revealing that σχ and σV were the paramount influencers of HECCs' phase structures. Notably, when σχ and σV were below 0.079 and 0.125, single-phase HECCs were more likely to be formed. This work is expected to facilitate the discovery and design of HECCs with bespoke phase structures and properties.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 5","pages":"1705 - 1722"},"PeriodicalIF":2.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145646280","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}

According to the kinetic study, the photodegradation process followed pseudo-second-order model. Optimal dosages were 2.8 g/L for ZnO–NPs and 2 g/L for PMMA/ZnO-NPs composites. PMMA/ZnO-NPs composites demonstrated moderate recyclability over four cycles, making them suitable for sustainable water purification applications. This work highlights the potential of ZnO–NPs/PMMA as cost-effective, thermally stable, and efficient photocatalysts for environmental remediation.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 5","pages":"1853 - 1869"},"PeriodicalIF":2.1,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145646160","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}
