In this work, we constructed the solution-crystal models to investigate the growth morphology of α-HH in Na2SO4 solution system by molecular dynamics simulation. The attachment energy (AE) model was used to predict the growth behavior of α-HH, revealing that the (002), (200), (110), and (1–10) crystal faces are dominant, with the (002) face exhibiting the highest attachment energy and predicted fastest growth rate. Molecular dynamics simulations of α-HH in Na₂SO₄ solution with varying mass fractions (2%–12%) revealed that the interaction energy between the solution layer and crystal faces follows the order: (002) > (1–10) ≈ (110) > (200). Radial distribution function analysis indicated the presence of hydrogen bonds, chemical bonds, van der Waals forces, and electrostatic interactions between the solution layer and crystal faces. Notably, the diffusion coefficients of Na⁺ and SO₄2⁻ ions were highest on the (002) crystal face, suggesting enhanced diffusion on this face. These findings provide insights into the structural and morphological transformations during α-HH crystal growth, offering a foundation for optimizing growth conditions, manipulating crystal size and morphology, and ultimately guiding the production of high-quality α-HH crystals.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148048301","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}

The disc-shaped ceramic membranes were fabricated by uniaxial pressing and sintered at 1100, 1150, and 1200°C. The sintered samples were characterized by X-ray diffraction (XRD), porosity, density, mechanical strength, mercury porosimetry, and scanning electron microscopy (SEM). Distilled water flux tests were conducted in a tangential flow system to evaluate the permeability of the ceramic membranes. The X-ray diffraction results indicated the presence of sapphirine and cordierite. It was found that the incorporation of PSP up to 30 wt.% promoted an increase in the porosity, pore size, and permeability of the membranes. The membranes with 20 wt.% and 30 wt.% of PSP sintered at 1150°C were highlighted in this study. These membranes were observed porosity of 40% and 49%, similar pore sizes of 6.2 µm, and flexural strength values of 22 and 17 MPa, respectively. Moreover, tests with distilled water conducted at 0.5 bar showed fluxes of 2791 and 2316 L·h−1·m−2, respectively. The results suggest the use of these membranes in effluent treatment.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148048039","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}

We are also studying ultralow-power artificial intelligence (AI) ALUs using AiMC FETs in the subthreshold regime. This report will introduce the trend of these technologies.

Flat-disc SiC membranes, with ∼37% porosity, were prepared via controlled dip-coating and characterized by x-ray diffraction (XRD), SEM, x-ray fluorescence (XRF), air permeability, and liquid permeation tests (isopropyl alcohol, IPA; on-spec biodiesel). Air permeation analysis yielded Darcian (k1) and non-Darcian (k2) permeability coefficients of 3.27 ± 0.19 × 10−15 m2 and 5.68 ± 0.19 × 10−12 m, respectively. Crossflow microfiltration of crude and neutralized biodiesel at 3 bar and ∼25°C showed acceptable permeance with IPA (10.7 ± 2.2 L/h m2 bar) and on-spec biodiesel (5.63 ± 1.69 L/h m2 bar). However, severe flux decline occurred with crude biodiesel, indicating fouling. Critically, ZnO–SiC membranes effectively reduced calcium (64.5–16.6 mg/kg), sodium (8.2–0.96 mg/kg), and phosphorus (25.8–8.6 mg/kg) to compliant levels. Sulfur removal was minimal, suggesting ZnO limitation against stable organosulfur compounds under mild conditions. These findings position ZnO-functionalized SiC membranes as robust polishing systems for selective metal and polar contaminant removal, while highlighting the need for integrated catalytic or hybrid strategies for sulfur reduction.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148050448","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}

Thus, it is essential to predict the physical properties of slags, as this phenomenon depends on their density, surface tension, and viscosity. Although thermodynamic calculations provide insights into the chemical composition of slags in equilibrium with liquid steel and refractories, and commercial software packages (such as FactSage) include modules to estimate slag viscosity, there are limitations regarding the chemical species considered and the properties that can be forecasted. In this study, predictive models of surface tension, density, and viscosity are evaluated for their ability to estimate experimental properties of metallurgical slags. These models, developed for glass compositions using machine-learning algorithms, were subsequently validated on slags in this work. On the basis of their performance and limitations, a framework coupling FactSage and GlassNet was proposed and applied to investigate potential slag conditioners for controlling foamy slag. The tested candidates were silica sand, sodalite, and steel scale, and their effects on the characteristic times of foam collapse (or aging) were predicted in the results.","PeriodicalId":13948,"journal":{"name":"International Journal of Ceramic Engineering & Science","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ces2.70050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148050218","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}
