Though silver is a good conductor, carbon is cheaper, and the nanotubes provide the extra electricalconductivity needed.
因此虽然银是良好导体，碳也很便宜，但是纳米管却可以额外提供必需的导电性。

Their solution was to take advantage of graphene’s electricalconductivity, by running a current through the mixture.
这个万全之策就是利用石墨烯的导电性能，在混合过程中联通电流。

The second desideratum, of low thermal and high electricalconductivity, was achieved by dividing the bismuth telluride into pellets a few nanometres across.
