"Zoomed-in view on a black-coated copper plate, with the focus on carbon nanotubes (CNTs) arranged in one direction beneath the coating. The black layer's thickness at 20 micrometers and CNTs sized at 200 nanometers by 500 micrometers are visible, showcasing the unique texture and the subtle sheen of copper beneath" Created Using: electron microscopy style, nano-scale accuracy, high contrast, detailed texture analysis, metallic sheen, scientific documentation, depth layering, ambient lighting --ar 1:1  --s 750 --style raw
