Carbon-based nanocomposites serve as a pivotal conduit for the extensive utilization of CBNs. Their functional performance is commonly tailored through approaches such as functional modification, doping, interface engineering, and multiscale structural design. A systematic discussion is presented on the current design strategies of nanocomposites incorporating carbon dots (CDs), carbon nanotubes (CNTs), and graphene-based nanomaterials (GBNs). Representative cases illustrate their significant engineering application potential in five rapidly evolving and highly active fields: electronic devices, energy storage, civil engineering, water treatment, and biomedical engineering. This review provides a comprehensive overview of recent advances in CBNs, emphasizing key applications, ongoing challenges, and emerging research opportunities across diverse domains. Interdisciplinary collaboration is poised to further drive innovation, particularly in areas such as energy storage, structural health monitoring, and biosensing. Future advancements are expected to focus on advanced material design, sustainable and scalable fabrication, intelligent optimization using artificial intelligence, interdisciplinary collaboration, and systematic validation to overcome challenges in synthesis, performance, commercialization, and integration. These insights collectively underscore the pivotal role of CBNs in shaping multifunctional, cross-cutting solutions for next-generation engineering systems.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"19 ","pages":"Article 100363"},"PeriodicalIF":9.0,"publicationDate":"2025-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145698043","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}

However, designing an optimal mix of these waste materials is challenging due to their potential impact on the concrete properties. To address this challenge, this paper presents a novel meta model that introduces a non-deterministic mix design framework and simultaneously optimizes four performance metrics: environmental (global warming potential), durability (rapid chloride permeability and bulk electrical resistivity), mechanical (compressive strength and splitting tensile strength), and workability (air content and slump). The model is trained using a hybrid dataset combining literature data with response surface methodology (RSM) generated samples. To this end, a Multilayer Perceptron (MLP) neural network is trained to capture the effects of waste materials, including shredded rubber (SR), glass powder (GP), and biomass fly ash (BFA), on concrete performance and is further combined with Monte Carlo simulation to identify optimal mix designs based on specific performance targets. The results demonstrate the AI model’s accuracy in predicting concrete performance, as evidenced by statistical measures such as root mean square error (RMSE), mean absolute error (MAE), and the coefficient of determination (R²). This accuracy is further validated by comparing the AI predictions with laboratory concrete mix results. The results indicated that a 23.1% increase in compressive strength and an 83% decrease in chloride ion permeability were achieved by partially substituting 30% GP for cement. The incorporation of 15% BFA consistently reduced slump by 65% and increased air content by 49%. Moreover, the control mix had the highest GWP at 325 kg CO₂-eq/m³. Using 30% GP, 15% BFA, and 15% SR reduced it to 135 kg CO₂-eq/m³, a 41% decrease. Additionally, the back analysis provides optimized mix designs tailored to specific performance constraints. According to the specified target for designing low-carbon, chloride-resistant, and normal strength (45–55 MPa) concrete, a mixture of waste materials with SR = 3.2%, GP = 25.8%, and BFA = 7.4% is proposed by the developed meta model.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"19 ","pages":"Article 100364"},"PeriodicalIF":9.0,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145739038","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}

However, it remains unclear whether polymer modification can alter these emissions. This study systematically assesses how styrene–butadiene–styrene (SBS) modification influences the effects, mechanisms, and environmental impacts of organic emissions from base asphalt, using an integrated approach spanning environmental science, toxicology, chemistry, surface science, and rheology. The results show that SBS polymer effectively reduces emissions of multiple organic compounds and suppresses the formation of secondary air pollutants, odor nuisance, and human health risks. Among the tested dosages, a dosage of 4.5 % SBS leads to the greatest mitigation effect. Based on compound identification and prior literature, secondary pollutant formation and odor nuisance are driven mainly by certain n‑alkanes, whereas health risks are predominantly associated with polycyclic aromatic hydrocarbons (PAHs). Beyond mitigating environmental and health risks, SBS polymer improves asphalt binder performance, including surface free energy characteristics, rheological behavior, and structural phase transitions. These benefits are likely attributed to the unique network structure and physical cross‑linking between SBS and asphalt binder. Overall, the findings elucidate the effects, mechanisms, and environmental implications of SBS modification that reduces organic emissions from base asphalt, thereby advancing the development of cleaner, high‑performance, sustainable, and health‑protective paving materials and technologies.</div></div>","PeriodicalId":100254,"journal":{"name":"Cleaner Materials","volume":"18 ","pages":"Article 100361"},"PeriodicalIF":9.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145617756","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}

Combined computational and experimental analyses reveal that thiourea derivatives construct a dynamic adsorption layer at the electrode/electrolyte interface, increasing the nucleation overpotential. Meanwhile, the electron-donating coordination of thiourea derivatives regulates the solvation structure of Mn²⁺ and reduces interfacial water activity.

The hydration behavior was analyzed using isothermal calorimetry, X-ray diffraction, thermogravimetry, and Fourier transform infrared spectroscopy. Rheological properties were assessed using a rheometer, penetration tests, and flow table tests. Additionally, the mechanical response of MSWI bottom ash-based printed mortar under compressive and flexural loading was evaluated.

The last decade of research has led to significant breakthroughs in the development and application of self-healing capsules for asphalt concrete. However, optimally tuning the use of these materials still has not been achieved, in part due to the multitude of mechanisms at play. Unlike prior single-scale studies, this study establishes a multiscale laboratory framework to evaluate nine rejuvenator capsule types at four levels, including capsule, binder, fine aggregate matrix (FAM), and asphalt concrete (AC), to systematically link capsule rupture and chemical diffusion behavior with mixture-level fatigue and rutting responses. This cross-scale validation clarifies inconsistencies in earlier studies and provides a transferable pathway for capsule design from laboratory to future pavement application. With nine capsule designs, the study examines key capsule design factors, including shell thickness, healing agent type, healing agent concentration, and capsule content in the mix. The findings suggest that capsule properties are strongly influenced by the chemical composition of the healing agent, alginate shell concentration, and the capsule shell. Capsules containing bio-oil contributed to a softer mixture and facilitated a higher diffusion rate. To optimize healing efficiency, capsules with varying shell thicknesses and rejuvenator types could be deployed to prevent premature release and maximize the use of healing agents. Additionally, capsules with a higher rejuvenator content proved more effective in addressing severe damage, while a higher overall capsule content was better suited for mitigating widely distributed minor damage.
