However, their development is limited by the low energy density. Ionic liquids (ILs) have wide electrochemical windows as electrolytes, which can effectively enhance the energy density of supercapacitors. However, the viscosity of ILs is generally large, which affects the power density of supercapacitors. Adding solvents is a simple and effective method to reduce the viscosity, which can effectively improve the dielectric constant and conductivity of ions. Here, we make an in-depth theoretical investigation of the IL-electrolyte systems by molecular dynamics simulations, with the cations of 1-ethyl-3-methylimidazole ([EMIM]⁺), 1,3-dimethylimidazolium ([MMIM]⁺), or 1- methylimidazolium ([MIM]⁺), and the acetate ion ([AC]^-). Then, we use ethanol as the organic solvent to explore the effects of solvents. The conductivity and double layer capacitance of these three IL-systems with/without ethanol solvent were systematically calculated from the perspective of improving power and energy density. Among them, the [EMIM][AC] - ethanol system shows the best performance, with the conductivity of 194.9 mS/cm². The maximum value of the double layer capacitance is enhanced from 5.4 μF/cm² (+1.5 V) to 6.1 μF/cm² (+1 V) with the addition of 35 % ethanol.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"340 ","pages":"Article 130854"},"PeriodicalIF":4.3,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhancing the activity of furnace ferronickel slag (EFS), as a substitution of MgO, is of great significance for mitigating the high carbon emissions and high cost of MPC. In present study, the technology of wet grinding was provided to tackle the issues of sluggish dissolution and limited activity of EFS. The properties of EFS-MKPC composites were systematically analyzed cured in humid condition, including three different fineness levels of EFS (D50 : 14.5 μm, 10.5 μm, 6.12 μm) and three varying contents of EFS (15 %, 30 %, 45 %). Heat of hydration, X-ray diffractometer (XRD), thermogravimetric analysis (TG), mercury intrusion porosimetry (MIP) and scanning electron microscopy (SEM) were used to explore the hydration reaction and microstructures changes. The results showed that wet grinding enhances the dissolution of magnesium and substantially improves the initial hydration activity of EFS. The 1 d compressive strength of EFS-MPC with 30 % and 45 % EFS reaches 119 % and 100 % of that of the control. The results of XRD and TG also proved that the hydration reaction of EFS is promoted and the effect is more significant with the extension of grinding duration. Meanwhile, the microstructures of EFS-MPC were optimized by incorporating fine EFS under humid conditions, which may be related to the activated silica from EFS.

Uniform distribution of SiC_p and C_f was observed in the as-cast composite. The thermal deformation behavior of the hybrid (SiC_p-C_f)/AZ91 composites with the high volume fraction was firstly studied based on the true flow stress-strain curve and the evolution of the thermal processing map. The increase in temperature and reduction in strain rate led to lower stress values on the true stress-strain curve. Furthermore, as the strain increased, the area of the instability zone in the thermal processing map gradually diminished, and the activation energy decreased. Calculations and simulations identified the workability region of the composite material as 680–773 K and 0.003 to 0.1 s⁻¹. Based on these findings, hot extrusion of high volume fraction magnesium matrix composite was successfully initiated for the first time. During extrusion, fracture and directional alignment of C_f along the extrusion path enhanced the flow of the matrix alloy AZ91 and SiC_p, thereby facilitating deformation. Compared to the as-cast composite, the extruded composite exhibited reduced porosity and enhanced mechanical properties, with ultimate tensile strength and elastic modulus reaching 370 MPa and 157 GPa, respectively. Additionally, the thermal expansion coefficient of the extruded composite was approximately 50 % lower than that of the AZ91 alloy.

Herein, ultra-fine Al₂O₃ nanofibers which are further self-assembled to form uniform rod-like morphology (R–Al₂O₃) were fabricated via a facile sol-gel strategy and further utilized as support to dispersing vanadium species (V/R–Al₂O₃). The physicochemical properties of the samples were systematically characterized by XRD, Raman, SEM, TEM, H₂-TPR, CO₂-TPD, XPS, and ²⁷Al MAS NMR techniques. It is found that except that R–Al₂O₃ support has the merits of a high specific surface area, lager pore volume, and uniform mesopore structure, the presence of the unsaturated pentacoordinate Al³⁺ ions plays a pivotal role in better dispersing V active species, with the existence of the isolate and/or polymeric forms. As compared to V/C–Al₂O₃ (commercial Al₂O₃ as support), the V/R–Al₂O₃ catalyst endows outperformed catalytic performances for oxidative dehydrogenation of ethylbenzene in the presence of CO₂ (OEBDH-CO₂). In which, the V/R–Al₂O₃ catalyst gives a high EB catalytic activity and good stability without significant deactivation phenomenon being detected even after the third regeneration test. Such a result can be principally ascribed to that R–Al₂O₃ support with excellent textural properties can better disperse V species so as to expose more active sites, which is beneficial for improving the conversion efficiency of EB. More importantly, keeping/regaining high valence state of V species in the V/R–Al₂O₃ catalyst under CO₂ as a soft oxidant effectively promotes Mars-Van Krevelen redox cycle, further suppressing the catalyst deactivation. This work provides a rational design strategy for a high efficiency and stable dehydrogenation catalyst by optimizing the textural properties of Al₂O₃ support and introducing the unsaturated pentacoordinate Al³⁺ ions.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"340 ","pages":"Article 130818"},"PeriodicalIF":4.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photocatalytic degradation studies provide further validation of our findings.
