Özet

Graphenic carbon can be etched into arbitrarily complex and preset channel patterns using cobalt-based catalyst particles for the dioxygen reaction at low temperatures in externally applied magnetic fields. Scanning electron microscopy images demonstrate active steering for particles/channels down to 200 nm (see image).
