Prompt Description

Style: Clean scientific schematic with a white background, minimal text, and flat vector icons arranged horizontally. Left-to-right flow, emphasizing a scientific approach with no legends and concise text. Layout: Two connected panels: Stage 1 (left) transitions to Stage 2 (right). Stage 1: Electro-Assisted Dark Fermentation (DFMEC). A single anaerobic reactor contains an anode and cathode, connected to a power supply illustrating electron flow from anode to cathode. Inputs: Food waste (C-rich), swine manure (N-rich), optimized C/N ratio, and self-buffering. Inside the reactor: Mixed fermentation broth and SCG-derived biochar coated with a redox-active polymer. Short label: "Zoom in showing Redox-engineered SCG–PEDOT biochar." Key functions (icons): Electron shuttling / DIET. Electrode potential control → NADH/NAD⁺ regulation, indicating that a higher ratio enhances H₂ production, while a lower ratio enhances VFA production. Outputs: H₂ gas (bubbles leaving the reactor). Effluent arrow labeled: "VFA-rich (acetate)". Stage 2: Microbial Electrolysis Cell (MEC).
