Pentagon-heptagon carbon nanoribbon conducts like a metal, in short pieces

A carbon nanoribbon built only from five- and seven-membered rings conducts like a metal, a Nature study reports, though only in short pieces grown on silver.

What it does not show Metallic behaviour is inferred for long ribbons from segments about 20 repeat units (about 10 nm) long, made in low yield (17.4%) on silver; no device was built.

How SciQuest reports

Interesting science is stronger when readers can inspect the evidence.

Our editorial standard requires every substantive story to identify what was observed, how it was measured, what researchers infer and what remains uncertain.

  1. 01
    Find the primary evidence

    Start with the paper, dataset, mission record or official technical source.

  2. 02
    Test the central claim

    Check the method, numbers, scope, uncertainty and alternative explanations.

  3. 03
    Explain without inflating

    Make the significance clear while preserving limits and scientific context.
