  • Application Solution Detecting CO and NO2 Gases

    Detecting CO and NO2 requires sensors to be placed such that a concentration of gas will diffuse to the location of the sensor in a reasonable and safe amount of time Relative to air, CO has a lower density; NO2 has a higher density Lower (or similar) density gases, such as CO diffuse with air quickly

  • Single-layer stanane as potential gas sensor for NO2, SO2

    A new hetero CaS/CaSe bilayer sensor for environmental toxic NO 2 gas is reported with excellent adsorption energy, quick recovery time and large sensitivity. A total of sixteen possible locations for NO 2 molecule are considered on both the CaS and CaSe surfaces of CaS/CaSe for investigation under density functional theory (DFT) and DFT-D2 method of Grimme.
