We have investigated the effects of metal decoration on the gas-sensing properties of a device with two-dimensional (2D) molybdenum disulfide (MoS2) flake channels and graphene electrodes. The 2D hybrid-structure device sensitively detected NO2 gas molecules (>1. 2 ppm) as well as NH3 (>10 ppm). https://www.pomyslnaszycie.com/halloween-skull-bride-groom-cheap/
