Based on the core content of your article (a novel fluorinated surfactant system based on β-cyclodextrin-polyethylene glycol conjugates for stabilizing IL/scCO₂ microemulsions), here's a professional, clear, and visually appealing graphical abstract design concept. --- ### I. Core Design Concept Use a **"left-to-right" visual narrative flow** to summarize the entire study: **Molecular Design → Interfacial Assembly → Functional Application**. Ensure the graphic is clearly discernible in a single-column width. ### II. Suggested Composition (Three-Part Layout) **Part 1 (Left): Molecular Structure and Design** * **Visual Elements**: 1. Draw a simplified model of **β-cyclodextrin (β-CD)** (like a truncated cone or cylinder, using lines to represent glucose units). 2. Within the cavity of β-CD, embed a simplified model of the **imidazolium cation ([Bmim]⁺)**, highlighting the butyl chain extending into the cavity, using **dashed lines** or a **glowing effect** to illustrate the **host-guest inclusion interaction**. 3. From one end of β-CD, extend a **wavy line** representing the **PEG chain**, and label it "PEG" or "CO₂-philic" at the end. 4. Draw a simplified structural formula of the **BCA molecule** next to it, and use an **arrow** pointing to β-CD to indicate that it is included as a "guest." 5. Near the PEG chain or on BCA, schematically add the functional group symbols for **thiol (-SH)** and **acrylate (C=C)**, laying the groundwork for dynamic crosslinking. * **Caption/Title**: **Molecular Design: Host-Guest Surfactant Conjugate** **Part 2 (Middle): Interfacial Assembly and Reinforcement** * **Visual Elements**: 1. Draw a clear **interface**, with the upper part using a light blue background and CO₂ molecule models (•) to represent the **scCO₂ phase**, and the lower part using a light green or yellow background to represent the **ionic liquid (IL) phase**. 2. At the interface, arrange multiple **β-CD-PEG molecules from Part 1**, with their β-CD heads immersed in the IL phase (including [Bmim]⁺) and their PEG tails extending into the scCO₂ phase. 3. Crucially: between these arranged molecules, draw a **network structure of covalent bonds** (which can be achieved by connecting thiol and acrylate sites with short chains), forming a **"crosslinked network"** covering the interface. 4. Label the network with ***G′ > G″*** or **Elastic Film**

Graphical Abstract Abstract Due to the high toxicity and low degradability of phenolic compounds, including hydroquinone (HQ), in environmental samples, there is a strong need for the development of efficient catalytic systems for the oxidation of hydroquinone to benzoquinone (BQ). Catalytic oxidation using nanoscale metal-based catalysts has been recognized as an effective approach for the removal of such contaminants. In this study, reduced graphene oxide-based iron oxide, iron nitride, and cobalt ferrite nanocomposites were synthesized using co-precipitation, pyrolysis, and hydrothermal methods. The obtained nanocomposites were characterized by UV–Vis spectroscopy, X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area analysis, and field-emission scanning electron microscopy (FESEM). The catalytic performances of the synthesized nanocomposites toward the oxidation of hydroquinone to benzoquinone using H₂O₂ in aqueous solution were comparatively evaluated. The results

Electrolytic Refining of Copper: A scientific schematic diagram in 16:9 format. The visual style is a high-definition educational vector illustration, rendered as a flat 2D cross-section with subtle depth shading. The color palette includes a white (#FFFFFF) or light grey (#F5F5F5) background; metallic copper orange (#B87333) for copper metal; vibrant translucent blue (#0096FF) for the electrolyte; dark grey/brown sludge (#4A4A4A) for impurities; and black (#000000, sans-serif font) for labels. Clarity is prioritized through a minimalist but detailed approach, ensuring clear separation of components. The scene composition features a rectangular electrolytic tank made of glass or transparent plastic, filled to 75% with the blue electrolyte. Electrodes are present.

Develop a laboratory workflow diagram illustrating the migration testing of chemical substances from recycled PET (rPET) bottles into food simulants, adhering to EN 13130-1 and Commission Regulation (EU) No. 10/2011. The workflow should encompass the following sequential steps: 1. Receipt and inspection of 600 ml food-grade 100% rPET bottles. 2. Filling of bottles with a 3% (w/v) acetic acid solution as a food simulant, employing the article-filling method. 3. Sealing of bottles with Parafilm to mitigate evaporation. 4. Incubation at controlled temperatures of 20 °C, 40 °C, and 60 °C for a duration of 10 days. 5. Collection of the simulant following the designated migration period. 6. Storage of collected samples at 4 °C prior to analysis. The workflow should be presented as a clear, step-by-step flowchart, with arrows delineating the sequence of operations. Employ professional laboratory terminology and maintain a concise, academic style suitable for inclusion in a scientific thesis or journal article.

Electrolytic Reduction of Fused NaCl: An educational diagram illustrating the electrolytic reduction of molten sodium chloride (NaCl). The diagram features a clean, professional scientific illustration with clear, legible labels and arrows, employing distinct color coding for ions and electrodes against a white or light grey background. The setup includes an electrolytic tank, depicted as a U-shaped vessel or beaker, containing molten NaCl electrolyte in the liquid state, with Na⁺ (liquid) and Cl⁻ (liquid) ions present. Inert electrodes, such as graphite or platinum, are used. The anode, located on the left side and designated as positive (+), is labeled as the site of oxidation. The process description indicates that Cl⁻ ions migrate to the anode, lose electrons, and form Cl₂ gas. Visual effects may include the movement of Cl⁻ ions toward the anode and the evolution of chlorine gas.
