This study proposes a novel hemispherical -shaped solar distiller (HSD) with integrating jute wicks and thermal storage materials (TSM – paraffin wax mixed with graphite and aluminum oxides nanoparticles) for enhanced potable water production in remote areas. The HSD had 5000 cm² projected area. Compared to the conventional solar distiller (CSD), the freshwater production of HSD was improved by 90.74 % and 41.73 % with and without TSM, respectively. The implementation of electric heaters (20 W) and an external condenser further propels freshwater production, reaching a significant 145 % improvement compared to that of CSD. The HSD exhibits superior performance as compared to CSD based on the freshwater production and efficiency parameters. With all enhancements integrated, the daily distillate yield reached 6370 mL/m², and both energy and exergy efficiencies were 48.2 % and 4.9 %, respectively. Moreover, the environmental factor for CSD, HSD, HSD with TSM, HSD with TSM &amp; heaters, and HSD with TSM, heaters &amp; condenser is determined as 13, 18.4, 24.8, 29.7, and 26 tons CO₂ a year respectively. Economically, the HSD proved its merit with a significantly reduced cost per liter of distilled water. While the CSD had a cost of $0.32 per liter, the HSD with all enhancements reduced this cost to $0.19.

However, their practical applications have impeded by the substantial voltage attenuation on cycling. The irreversible evolution of oxygen triggers transition-metal (TM) migration and structural rearrangements, resulting in the voltage decay. Herein, a linkage-functionalized modification approach to tackle these challenges. The strategy involves the synchronous formation of an amorphous CuO coating, inner spinel structure, and oxygen vacancies on the surface of R-LNCM microspheres, effectively stabilizing the lattice oxygen evolution and suppressing structural distortion. Importantly, this three-in-one surface engineering approach is characterized by its environment-friendly attributes, cost-efficiency and seamless scalability. The corresponding cathode delivers a high specific capacity 298.2 mAh g⁻¹ with initial coulombic efficiency (ICE) 95.18% at 0.1 C. The voltage decay and the capacity retention rate are 1.70 mV cycle⁻¹ and 90.5% after 200 cycles at 1 C. The density functional theory shows that the diffusion energy barrier of Li⁺ in Li₂MnO₃ can be reduced by introducing vacancy. Moreover, the introduction of spinel structure in R-LNCM material improves the stability and diffusion ability of R-LNCM. Therefore, the novel insight and method have a potential to make a significantly contribution to the commercialization of R-LNCM for high energy density batteries.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"30 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143471037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, hydrophobic polymer/ionic liquid (IL) composite coatings have emerged as effective solutions for enhancing anti-icing properties. In this study, we explored the potential of a poly(dimethylsiloxane) (PDMS)/IL/SiO₂ nanoparticle (NP) composite, employing two synergistic strategies: superhydrophobicity to reduce the ice/coating contact area and IL-induced quasi-liquid layer (QLL) formation to improve anti-icing performance. Density functional theory (DFT) calculations and structural analyses were performed to confirm IL dispersion within PDMS matrix, highlighting ion–dipole interactions between PDMS and 1-ethyl-3-methylimidazolium-bis(trifluoromethylsulfonyl)imide (EMIMTFSI). IL-integrated PDMS/SiO₂ composite exhibited a water contact angle (WCA) and water sliding angle (WSA) of 166.6 ± 0.5° and 4 ± 1°, respectively. The PDMS/IL/SiO₂ NPs composite coating exhibited an ice adhesion strength (IAS) of 19 ± 1 kPa, which is four times lower than that of the PDMS/SiO₂ NPs composite. Additionally, the IL-integrated superhydrophobic composite exhibited the FDT of 325 ± 6 s, representing a 14-fold increase compared to that of a bare Al substrate. Overall, the IL-integrated coatings exhibited superior superhydrophobicity and QLL formation, leading to significantly improved FDT and a notable reduction in IAS.
