Two limitations are the slow kinetics of sulfur reactions and the lithium polysulfide (LiPSs) shuttle phenomenon. This research has advanced Li-S batteries by synthesizing and introducing a Fe-doped MoS₂ and WO₃ intercalated multilayer rGO composite (Fe-MoS₂-WO₃@rGO) as an electrocatalyst. WO₃ attaches to polysulfides, stopping dissolution into the electrolyte, while the MoS₂ promotes electron transport and strong binding at the separator. Doping the iron (Fe) element may expose additional anchoring active sites, which reduce the shuttle effect. Thus, the Fe-MoS₂-WO₃@rGO could balance polysulfide immobilization and catalytic activity, leading to high performance of the cell. The Li-S cell using a separator consisting of Fe-MoS₂-WO₃@rGO/PP delivers a significant capacity of 442 mAh g⁻¹ after the 1000th cycle at 1.0 C. Moreover, under a substantial current of 5.0 C, the cell consistently retains a 415 mAh g⁻¹ capacity for 700 cycles. Furthermore, the tri-layer sulfur cathode cell provides a capacity of 6.1 mAh cm⁻² after completing the 100th cycle (under the condition of 8.19 mg cm⁻² sulfur loading). The findings of this study demonstrate the successful construction and utilization of the Fe-MoS₂-WO₃@rGO functional mediator in Li-S cells, resulting in enhanced electrochemical performance. Besides, it facilitates the development of an innovative multi-layer cathode technology to boost the efficiency of Li-S cells.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"737 ","pages":"Article 139704"},"PeriodicalIF":5.4,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its implementation is limited by the lack of standardized, mechanistically grounded optimization strategies that address the multifactorial nature of printability. Herein, a stepwise and multi-parametric protocol is proposed to streamline the optimization of materials printed via SSE-3DP through a comprehensive structure–property–performance framework. Two gelatin-based model inks, differing in the content of PEG-40 hydrogenated castor oil (PEG40 HCO), were used to validate the approach. Rheology, texture, thermal-imaging and contact angle measurements were performed as part of the pre-printing workflow to elucidate ink structure and interfacial behavior, while width, length, collapse, pentagram and z-stack assays were carried out to optimize the 3DP quality in-process, and macro and scanning electron microscopy (SEM) imaging were introduced as post-characterization validation tools. Rheological analysis revealed that PEG40 HCO lowers the Sol–Gel crossover temperature, increases viscoelastic moduli and reduces creep compliance, indicating enhanced resistance to deformation during extrusion. These property changes translated into higher extrusion forces and increased susceptibility to clogging, quantitatively predicted by texture analysis (R² ≥ 0.94). Interfacial studies identified acrylic as the optimal printing bed. Line fidelity was primarily governed by print speed, while controlled porosity emerged from the coupled optimization of filament spacing and printing path design. SEM confirmed that PEG40 HCO induces mesoscale reorganization of the gelatin network, yielding improved mechanical stability and geometric fidelity. Overall, this work provides a comprehensive and adaptable framework for SSE-3DP, advancing material-process-design optimization in 13 steps.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"737 ","pages":"Article 139780"},"PeriodicalIF":5.4,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, nFe–ZnO-modified kelp biochar (Fe–ZnO@BC) was synthesized and combined with AnGS to achieve efficient U(VI) removal. The results demonstrated that under optimal conditions—an initial U(VI) concentration of 80 mg/L, pH of 3, reaction temperature of 303 K, contact time of 24 h, Fe–ZnO@BC dosage of 0.1 g/L, and AnGS dosage of 3 g/L—the U(VI) removal efficiency reached 92.16 %, with a maximum adsorption capacity of 147.46 mg/g.

Although alcohol improves surfactant solubilization and interfacial behavior, its role is often simplified in existing optimum salinity correlations. This paper introduces an optimum salinity model that explicitly accounts for the alcohol volume fraction in surfactant–alcohol mixtures through multiplicative interaction coefficients among key formulation variables, including oil alkane carbon number (<em>ACN</em>), temperature (<em>T</em>), and alcohol fraction (<em>C</em>_<em>A</em>). We conducted over 120 salinity scans (48 primary and 72 repetitive scans) using sodium dodecyl sulfate (SDS) (4.29 wt%) and n-butanol (17.16 wt%, 10.73 wt%, and 8.58 wt%) with a series of pure alkanes (n-heptane, n-octane, n-decane, and n-dodecane) across four temperatures of 21, 30, 45, and 60°C at a fixed water-oil ratio of one. Optimum salinities (<em>S*</em>) were determined from unbiased linear fits of the inverse of the three-phase solubilization data. Linear relationships are observed between ln<em>S*</em> and <em>ACN</em>, <em>T</em>, and <em>C</em>_<em>A</em>. Although relationships are linear, the slopes were not always constant as other formulation variables changed, indicating potential interactions among <em>C</em>_<em>A</em>, <em>ACN</em>, and <em>T</em>. Accordingly, we developed a multiplicative interaction model for optimum salinity, including all interaction terms to account for potential synergistic behavior. The results show a significant interaction between <em>C_A</em> and <em>ACN</em> and a slight-to-moderate interaction between <em>C_A</em> and <em>T</em>. All other interactions were negligible. Including these interactions improves the global fit of measured optimum salinity data by 23 % compared to the conventional linear additive model. Furthermore, errors of 100 % in the estimated optimum salinity are possible for alcohol fractions outside the range of experimental data.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"737 ","pages":"Article 139707"},"PeriodicalIF":5.4,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ionized escin molecules at pH &gt; 4.7 form charged micelles that repel one another when there is no added electrolyte and solutions remain clear and stable for more than a month. Lowering the pH to 4 leads to formation of uncharged micelles. These micelles attract each other and form inter-micellar hydrogen bonds, which enable formation of micrometer aggregates that cause turbidity and phase separation. The addition of background electrolytes to the solutions at pHs of 6 and 8 screens the electrostatic repulsion between micelles, causing partial aggregation of the micelles and gelation of solutions. As the salt concentration increases, the viscosity of the escin solution also increases, reaching a maximum—similar to the behavior observed with conventional surfactants. However, the mechanism behind this viscosity maximum is different. In solutions of conventional surfactants, the maximum is due to the formation of worm-like micelles, whereas the maximum for escin solutions is due to formation of a network of escin aggregates that imparts yield stress and elasticity to the solution.
