While latent heat energy storage systems (LHES) using alkaline inorganic phase change materials are crucial, corrosion significantly impacts component lifespan, posing challenges to commercialization and reliability. This study develops sustainable aluminium hybrid reinforced composites (AHRC) via 3R principles of waste management strategy and examines their corrosive sensitivity considering the effects of (i) varying concentrations of Tungsten carbide (WC) and Red mud (RMD) reinforcements (ii) exposure to a 0.2 M concentrated aqueous sodium hydroxide, and (iii) process temperatures of RT, 40 and 60 °C. The AHRCs are stir-casted, and designated as AHRC_WR1, AHRC_WR2, and AHRC_WR3. The microstructural and hardness characteristics of the specimens are examined. Tafel, and EIS studies are performed to assess corrosion characteristics of the AHRCs. Dynamic corrosion studies are conducted for 30 days to assess weight loss and layer formed. Moreover, life cycle assessment (LCA) is conducted via “Cradle to Grave” approach. The static and dynamic corrosion study results are merely comparable. The AHRC_WR2 composite exhibiting hardness (61.85 BHN), demonstrates better corrosion resistance, outperforming the base alloy by 81.15 %, 37.75 %, and 42.60 % at room temperature, 40 °C and 60 °C, respectively. The corroded composite specimens form a compact corrosion product layer, enhancing durability. The LCA results emphasize that the produced composite reveals better energy consumption (334.32 MJ/kg) and CO₂ emissions (39.37 kg CO₂/kg). The findings support the development of a sustainable corrosion-resistant composite material for LHES applications in alkaline environments, aligning with SDGs 7, 9, and 12.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"45 ","pages":"Article e01533"},"PeriodicalIF":8.6,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144685964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It offers advantages such as a simple device structure, sustainability, and high efficiency in harvesting low-frequency mechanical energy. To address the low output charge density of traditional piezoelectric-triboelectric hybrid nanogenerator (PT-NG), this study proposes a charge excitation-enhanced PT-NG for improved performance. This innovative design enhances output performance by optimizing charge accumulation and transfer processes, enabling efficient energy capture even in weak vibration environments. In this study, silk fibroin film was prepared via electrospinning as the positive triboelectric layer, while a bead-like P-PVDF/MoS₂ composite film served as the negative triboelectric layer. Leveraging the triboelectric series difference and interfacial effects, these two functional films were assembled to successfully construct a PT-NG. However, low output charge density limits its practical application. To enhance the triboelectric output, a charge excitation-enhanced PT-NG was proposed. Experimental results demonstrated that, under working conditions of 2 Hz frequency and 3 N mechanical force, the voltage output reached 35 V under excitation, the excited current output was 3 μA, and the peak instantaneous power density reached 1 W/m². Even under weak vibrations, the device achieved high power output, with the current increasing by 50 % compared to the non-excited PT-NG. Additionally, the potential applications of this device were systematically explored, including powering electronic devices, environmental energy harvesting, and wireless alarm systems, providing a novel technological pathway for the development of self-powered systems.

While studies often relate moisture damage to aggregate types and compositions, this paper highlights the role of asphalt binder's acid value as a major contributing factor to moisture damage. While polar alkane acids in asphalt can improve adhesion in dry conditions, their high acid content exacerbates water-induced degradation at asphalt binder–aggregate interface. This study investigates the molecular-level mechanisms underlying moisture susceptibility, focusing on the role of asphalt's acid value in influencing desorption and water retention at the asphalt–aggregate interface. A combination of laboratory experiments, including contact angle measurements and moisture-induced shear-thinning index (MISTI) tests, and computational methods such as molecular dynamics (MD) simulations and density functional theory (DFT) calculations was employed. Experimental results revealed that binders with higher acid content exhibit increased moisture susceptibility, with contact angles as high as 155° for high-acid binders, a 2.65 % increase compared to neat asphalt binder. MISTI values also showed greater deviation from unity for high-acid binders, indicating weakened interfacial adhesion. MD simulations identified a critical acid content threshold of 8 %, beyond which hexadecenoic acid accumulates at the silica-water interface, forming micelles and disrupting adhesion. DFT calculations quantified the adsorption energy of hexadecenoic acid on silica as −36.7 kcal/mol, significantly higher than most asphalt components (−20.8 kcal/mol), further driving acid migration to interface, hence weakening the interface resistance to moisture damage. These findings emphasize the importance of chemistry-informed design of asphalt mixtures to optimize interfacial binding when exposed to moisture. By minimizing acid value in asphalt, particularly when using modifiers and rejuvenators, the durability of asphalt pavements can be significantly enhanced, reducing moisture-induced damage and promoting sustainable construction practices.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"45 ","pages":"Article e01520"},"PeriodicalIF":8.6,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144595643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
