The macro properties of SSM were the focus of systematic study, with the aim of gaining deeper insight into the response of the SSM to conditions such as freeze-thaw cycles, seawater erosion, dry-wet cycles and dry shrinkage. In order to facilitate this study, a range of analytical techniques were employed, including scanning electron microscopy (SEM), X-ray diffraction (XRD) and mercury intrusion porosimetry (MIP). The findings indicate that, in comparison with cement, the carbon emissions of SSM (A1) are diminished by 77.7 %, amounting to 190 kg/t, the carbon-performance ratio (24.4 kg/MPa), the cost-performance ratio (32.1RMB/MPa) and the carbon-cost ratio (0.76kg/RMB) are reduced by 86 %, 56 % and 68 % respectively. SSM demonstrated better performance in terms of freeze-thaw resistance, seawater erosion resistance and dry-wet resistance when compared to cement. The dry shrinkage value of SSM solidified soil was reduced by approximately 35 % at 40 days compared to cement solidified soil, due to compensatory shrinkage and a reduction in pores. In contrast to the relatively minor impact of seawater erosion and the moderate effects of the wet-dry cycle, freeze-thaw cycles have been shown to cause the most severe structural damage to the micro-structure of solidified soil. The conduction of durability tests resulted in increased porosity and the most probable aperture. The increase in pores and micro-structure leads to the attenuation of macroscopic mechanical properties of SSM solidified soil. The engineering application verified that with the content of SSM of 50 kg/m, 4.5 % and 3 %, the strength, bearing capacity and bending value of SSM modified soil were 1.9 MPa, 180 kPa and 158, respectively in deep mixing piles, shallow in-situ solidification, and roadbed modified soil field.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"31 ","pages":"Article 101135"},"PeriodicalIF":7.1,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084301","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}

In this study, hierarchical carbon nanoplates (HCN) fabricated through the carbonization of high aspect ratio, polycrystalline metal-organic framework nanoplates. These HCN structures are then hybridized with functionalized carbon nanotube (FCNT) scaffolds and applied as electrodes using a scalable shear-coating method, eliminating the need for binders. The synergistic effects of these components result in the capacitance of 206 F/g at 0.8 A/g and 148.8 F/g at 8 A/g with a retention of 72 % in half-cell setups, and a full symmetric cell capacitance of 126 F/g at 4 A/g and 76 F/g at 40 A/g with a retention rate of 61 %. The power and energy densities of the full cell were measured to be 3880 W/kg and 16.2 Wh/Kg, surpassing the upper bound for electrochemical capacitors. The high rate capability and capacitance are attributed to the well-designed architecture of the electrodes and the benefits of the carbon components. Specifically, the high aspect ratio of the HCN with the hierarchical pore structure enhances the active surface area and charge transport properties. Additionally, the increased intermolecular interactions within the FCNT phase create entangled scaffolds, imparting both conductive pathways and mechanical stability. The binder-free nature of the electrodes, complemented by the presence of HCN spacers in the FCNT matrix, expands pores and promotes the transfer of ion species.

Therefore, understanding the detailed mechanisms at the atomistic level requires insights into the fundamental electronic and structural properties, as well as the thermodynamic nature of the catalytic materials used.

In this study we present a simple cost-effective approach of zinc spray coating onto carbon fibre substrate (SCZn) as a simplified lean anode production strategy while enhancing the performance of Zn-ion batteries.

Furthermore, the micro-scaled Zn particles embedded in the 3D structure of the carbon fibres effectively supress dendrite growth and enhance the charge transfer kinetics, as evidenced by lower polarization, less corrosion and favourable impedance. Full cell studies were carried out by pairing the SCZn anode with a cost-effective commercial V<sub>2</sub>O<sub>5</sub>-based cathode.
