This work proposes a measurement‑informed data augmentation framework for small tabular datasets in materials science. The framework combines bootstrapping, interpolation, and controlled noise addition to expand training data while preserving the underlying statistical structure and metrological characteristics of the original measurements. It is evaluated on four heterogeneous experimental datasets (two adsorption problems, one cement density dataset, and one dredged sediment compressive strength dataset) using Linear Regression, Support Vector Regression, and XGBoost. Across all datasets, data augmentation yields consistent improvements in predictive accuracy and stability, with XGBoost benefiting the most; for example, the coefficient of determination R² for the Planning dataset increases from 0.29 to 0.90 after augmentation, and the Dredging dataset (dredged sediment) shows a substantial reduction in RMSE compared with the baseline model. Because the datasets are very small, these gains are interpreted together with measurement‑focused analyses of bias, uncertainty, repeatability, and residual behavior to avoid over‑stating generalization. The results demonstrate that simple, structure‑preserving augmentation, when combined with a metrological evaluation, can significantly enhance predictive modeling under severe data scarcity in materials science.</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"21 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40712-026-00521-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, this is addressed by incorporating montmorillonite (MMT) into polyacrylonitrile/polyvinylpyrrolidone (PAN/PVP) nanofibers to form PAN/PVP/MMT composite membranes. The nanocomposites were fabricated by electrospinning PAN/PVP solutions with different MMT loadings, followed by hot-water immersion and thermal stabilization. Structural and morphological characterization (X-ray diffraction, Fourier transform infrared spectroscopy, field-emission scanning electron microscopy/energy-dispersive X-ray spectroscopy, and thermogravimetric analysis) confirmed successful MMT incorporation. Batch adsorption experiments using methylene blue (MB, cationic) and Congo red (CR, anionic) showed that the optimal PAN/PVP/MMT7 membrane achieved equilibrium capacities of 38.2 mg/g for MB and 26.8 mg/g for CR, corresponding to ~ 3.8-fold and ~ 1.4-fold improvements over neat PAN/PVP. Kinetic data followed a pseudo-second-order model, and isotherm analysis indicated Langmuir behavior for MB, whereas CR was described comparably by both models. The pronounced selectivity for cationic MB over anionic CR arises from the permanent negative (cation-exchange) charge of montmorillonite together with the membrane’s point of zero charge, consistent with the pH-dependent adsorption, and the spent membrane was partially regenerable by NaCl. These results demonstrate enhanced adsorption capacity and charge-selective dye removal.</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"21 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40712-026-00523-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, EDD 513 steel used for manufacturing of automobile oil drain cup having thickness of 1.5 mm was investigated through finite element analysis (FEA) and experimental validation for deep drawing operation. Few simulations conducted during intital phase resulted in excessive thinning of approximately 16% along with severe wrinkling at the flange region, leading to rejection of the tooling design. Parametric investigations were performed by varying die entry radius range from (4–11 mm), varying friction coefficient, blank holding force and die-punch clearance (0.31 mm and 0.82 mm). The optimized conditions obtained through FEA simulations demonstrated that an 11 mm die entry radius provided acceptable formability and satisfied industry requirements for defect-free production.The thinning percentage was reduced to 14% with low wrinkle formation at body and flange.

Such films can be reliably fabricated using scalable thin-film deposition techniques, such as ultrasonic spray pyrolysis (USP). This work proposes an environmentally friendly, cost- and time-efficient USP deposition route for gadolinium-doped ceria (CGO) and yttria-stabilized zirconia oxide (YSZ) electrolyte films. The deposition employs water as solvent, water-soluble metal nitrates as precursors, and it is free of organic chelating additives. The absence of organic species from the precursor solution prevents residual carbon contamination, microstructural defects, and secondary phases that can otherwise compromise the films’ implementation in rSOCs. The deposition is systematically investigated using a design-of-experiments approach and subsequently refined to reduce processing time, while optimizing the film growth on scandium-stabilized zirconium oxide substrates. In a next stage, using the optimized deposition parameters, the electrolyte thin films are deposited onto alumina substrates for the characterization of their conductivity. At 700 °C, the 20 mol% gadolinium-doped CGO film exhibits a conductivity of 3.1 mS cm^− 1, while the 8 and 3 mol% yttria-doped YSZ films yield a conductivity of 0.9 and 0.4 mS cm^− 1 respectively. The functional performance of the CGO films is further validated in a symmetrical cell configuration, where the incorporation of a CGO diffusion barrier successfully suppressed interfacial degradation and secondary phase formation at the electrode/electrolyte interface. These results demonstrate the suitability and versatility of the proposed USP process for producing functional electrolyte layers for solid oxide cells.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"21 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40712-026-00500-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149034576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
