Simulation analysis of 787 CNTs and 787 SiNTs reveals that nanotube radius plays a critical role in determining CO₂/H₂ selectivity and CO equilibrium conversion. Among CNTs, (10,10) and (15,9) demonstrated the best CO₂/H₂ selectivity and CO₂ adsorption capacity. In SiNTs, (6,6) and (9,9) were considered the best choices due to their higher CO₂/H₂ selectivity and CO₂ adsorption capacity. SiNTs showed stronger gas adsorption capabilities and higher selectivity compared to CNTs, mainly attributed to their unique structural characteristics. Furthermore, changes in pressure significantly affected the reaction conditions within the nanotubes, especially the changes in CO₂ adsorption and mole fraction at low pressures. In conclusion, SiNTs have a clear advantage over CNTs in CO₂ capture and H₂ separation, offering new possibilities for future applications in carbon capture and hydrogen energy fields.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"9 ","pages":"Article 101033"},"PeriodicalIF":0.0,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144781234","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}

This study explores the use of fly ash (FA) and silica fume (SF) as supplementary cementitious materials (SCMs) to enhance both mechanical and environmental performance of PC concrete. Experimental investigations were performed using FA replacement levels of 20 %, 30 % and 40 %; and SF replacement levels of 7.5 %, 10 % and 15 % to determine optimal mix proportions for compressive strength, flexural strength, split tensile strength evaluation. Results indicated that a blend containing 30 % FA and 10 % SF achieved a 28 day compressive strength of 34 MPa representing a 51.1 % increase over the control mix as well as improved flexural (4.8 MPa) and tensile strength (3.3 MPa), while reducing porosity to 12.4 % and maintaining high permeability. It also resulted in a 4.7 % reduction in CO₂ emissions and 6.19 % lower material costs, supporting its suitability for sustainable infrastructure applications.

The different structural parameters, like crystallite size, shape, lattice constant, micro-strain and dislocation density, are determined from the X-ray diffraction peaks. The calculated lattice constants deviate from the bulk values, and their corrected lattice constant values are obtained from the Nelson-Riley plots. The average particle sizes obtained by using Scherrer’s formula are found in the range of 13.6 nm - 23.4 nm, which are correlated with the crystallite sizes obtained from different modified Scherrer’s methods. Crystallite size increases with an elevation in pH value, while dislocation density decreases from 5.4 × 10¹⁵ lines/nm² to 2.1 × 10¹⁵ lines/nm².

Consequently, this has led to the widespread presence of DCFS in water bodies, posing adverse effects on the entire biota.

Thus, this study investigated the WH as the precursor of activated carbon (WH-AC) for the adsorption of DCFS from an aqueous solution. The characterization analysis confirmed the successful synthesis of facile WH-AC. The RSM optimum condition for 100 % efficiency was determined to be 1.191 g/L dosage, 21.064 mg/L initial concentration, and 107 min contact time. Under the same conditions, the experimental efficiency was determined to be 97.9 %, which validates the RSM quadratic model.
