These ceria variants are meticulously investigated using the sol-gel combustion method to uncover their unique characteristics. The exceptional performance of stoichiometric ceria is particularly notable, as it exhibits a well-defined crystal structure and balanced elemental composition. Conversely, fuel-deficient and fuel-rich ceria variants display altered lattice structures due to variations in their oxygen-to-cerium ratios. The study extends to the incorporation of these variants of ceria nanoparticles into PVDF polymeric membranes by flat sheet membrane synthesis for water application. The different ceria variant’s surface charges and electronic vacancies play a significant role in water purification and emulsion separation. Capitalizing on their individual properties, ceria-modified membranes are systematically evaluated, for membrane performance in terms of flux, recovery ratio and reusability. Stoichiometric ceria-incorporated membranes emerge as superior performers with 1.7x oil-water separation efficiency and reusability compared to pristine membranes. Therefore, ceria nanoparticle incorporated membrane can be used for sustainable environmental remediation of pollutants from the water.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":"25 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139441722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weld bead geometry and dilution, governed by process parameters, impact cladding quality. This study examines weld bead geometry with welding current, speed, and nozzle-to-plate distance, creating equations to predict dimensions and control geometry. Method This research explores Cold Metal Transfer (CMT) cladding, emphasizing its interaction with parameters using ANOVA and orthogonal arrays. It uncovers patterns and correlations, leading to a robust mathematical model derived from a Definitive Screen Design in Surface Methodology. Results Process parameter changes particularly affect internal shape (bead width, dilution, penetration area) compared to external shape (penetration, reinforcement) using mathematical model. And the validity of the model is defined. Penetration is primarily affected by welding current and nozzle-to-plate distance, with higher current and smaller distances leading to deeper penetration. Reinforcement is minimally impacted by welding current, speed, and error but decreases with a larger nozzle-to-plate distance. Bead width increases with higher welding current and larger nozzle-to-plate distances, while the effects of welding speed and error are relatively small. Dilution is reduced by higher welding current and larger distances, but error can significantly increase dilution. Welding speed has minimal impact on dilution. Conclusion This study enhances the understanding of CMT cladding. By analyzing parameter interactions, it predicts and controls weld dimensions. Statistical tools reveal patterns, aiding in a strong mathematical model. Significant for industrial applications, it emphasizes the impact of parameters on the quality and structure of cladding using austenitic stainless steel.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":"109 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138999590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Waste concrete, waste bricks and steel slag - an industrial waste produced in large quantities in the country - were used as aluminosilicate sources. Waste concrete was used as fine aggregate (75 μm to 4 mm), while solid or hollow red clay bricks were used together with steel slag as aluminosilicate powders. Solid red clay brick (75 μm to 1.4 mm) was also used as fine aggregate in some mixes. Different alkaline activators including solid powder or ground pellet forms of Ca(OH)2, CaO, and Ca(OH)2-NaOH, NaOH-CaCO3 and Na2SiO3-Na2CO3-Ca(OH)2 mixtures were employed by just adding water. A few mixes included both solid powder Ca(OH)2 and viscous solutions of NaOH and NaOH-Na2SiO3 as alkaline activators. The geopolymer mortars also included small amounts of some other additives such as gypsum, microsilica and aluminium sulfate to enhance the geopolymerization and hydration process. Random proportions of the materials were considered in the range-finding experiments, and the mortars produced were tested for compressive strength. Results: The data show the 7-day compressive strengths and densities of the 40 mixtures considered with mostly ambient temperature (20°C) curing. It also shows such data for mixtures in which variables such as curing at 40°C, mixing with hot water at 50 - 60°C temperature, grading of waste concrete aggregates, and collective grinding of the powdered materials were considered. Conclusions: The dataset shows possible early-age compressive strengths of different geopolymer mortar mixture designs and the materials and mixture design methods that can be used to achieve desired early-age strengths from waste concrete and bricks.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46623206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limited research exists on the utilization of Taguchi's technique in welding and cladding processes. The main objective of the present research is to employ the Taguchi approach for determining the impact of CMT parameters on the cladding geometry of 316L stainless steel. Methods: The influence of process parameters on the weld bead was examined using both Signal-to-Noise (S/N) ratio and Analysis of Variance (ANOVA) by implementing an orthogonal array. A structural steel substrate was coated with nickel-based metal inert gas (MIG) welding wire using the CMT process while being shielded by a 99.9 percent pure argon gas. To attain the desired quality of weld bead, the CMT input parameters and geometry of the bead are separately and collectively optimized. Results: When the welding current (Iw) is set at 130A, welding speed (V) at 200 mm/min, and the distance between the nozzle and plate (X) at 5 mm, the Taguchi method indicates that the desired outcome is obtained with the following parameters: a penetration (P) of 1.115 mm, a reinforcement (R) of 1.51 mm, a bead width (W) of 4.265 mm, and a percentage of dilution (D) of 21.145%. Conclusions: The research findings indicate, under certain limitations, the techniques of the Taguchi method be utilized to efficiently manage the CMT cladding process parameters.","PeriodicalId":29806,"journal":{"name":"Materials Open Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48957377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
