superconductionn.

Brit.

/ˌsuːpəkənˈdʌkʃn/,

/ˌsjuːpəkənˈdʌkʃn/, U.S.

/ˈˌsupərkənˈdəkʃ(ə)n/

Origin: Formed within English, by derivation. Etymons: super- prefix, conduction n.

Etymology: < super- prefix + conduction n. Compare supraconduction n. and the Dutch noun cited at that entry, and also superconductivity n., superconducting adj., superconductor n.

Physics.

The conduction of electricity without any resistance; = superconductivity n.
