Prompt Description

APPROVED Scientific Illustration Style and Rendering Guidelines: Illustrations should adhere to a scientific illustration style, characterized by flat vector graphics, clean lines, and a white background. All figures must be high-resolution and suitable for publication. Color coding should be consistent with the following scheme: * Biological processes: green * Electrochemical processes: blue * AI & control intelligence: cyan Decorative or artistic elements are prohibited. Layout: The illustration should consist of four vertical panels arranged from left to right with balanced spacing and thin separators. Panel 3 (AI & integration) should be visually dominant. Panel 1 – Circular Feedstock Input: This panel should depict a circular feedstock input using standard scientific icons to represent food waste, animal manure, and wastewater. These inputs should converge into a single funnel labeled "high-strength organic feedstock." A circular arrow motif should be included to indicate the circular bioeconomy concept. No explanatory text is permitted in this panel. Panel 2 – Two-Stage Bioelectrochemical Conversion: * Top: A dark fermentation bioreactor (cylindrical vessel) should be shown. Arrows should indicate the conversion of organic matter into H₂ (gas bubbles) and a VFA-rich effluent. * Bottom: A schematic of a microbial electrolysis cell should be displayed, including the anode, cathode, proton exchange membrane, and external circuit.
