Figure 1. (A) Photographic images and (B) Scanning electron microscopy (SEM) micrographs for NanoWeb-RVC. (C) SEM micrographs of putative electroactive biofilms grown on NanoWeb-RVC after 140 days of inoculation. (D) Photographic images and (E) SEM micrographs for EPD-3D. (F) SEM micrographs of putative electroactive biofilms grown on EPD-3D 45 ppi after 63 days of inoculation. (G) Cumulative electron consumption, (H) CO₂ consumption, and (I) acetate production over time on graphite plate, unmodified RVC 45 ppi, NanoWeb-RVC 45 ppi, and EPD-3D 10 ppi, 45 ppi, and 60 ppi, normalized to projected surface area (left) and total surface area (right).
