Hybrid nanostructures consisting of multiwalled carbon nanotubes (CNTs) uniformly coated with SnO 2 nanocrystals can be used as a novel gas sensing platform, exhibiting high sensitivity to low‐concentration gases (NO 2 , H 2 , and CO) at room temperature, report Junhong Chen and co‐workers on p. 2487 . The hybrid nanomaterial provides a new opportunity to engineer sensing devices through electronic transfer between the nanocrystals and the CNT.
