Examples of NO2 in a sentence
The flask with its content was heated on a hot plate under a fume chamber until the production of red NO2 fumes ceased and the mixture turned colourless.
The electrons of the HOMO of the graphene/h-BN upon adsorption of CO, NO, and NO2 are located around the adsorbed molecules instead of being distributed at the edge of the scattering region for the graphene/h-BN without gas molecules on the surface.
The changes in the electronic properties positively impact the adsorption performances of graphene toward CO, CO2, NO, and NO2.
The black, red, green, blue, and orange curves indicate the trans- mission of the graphene/h-BN, CO + graphene/h-BN, CO2 + graphene/h-BN, NO + graphene/h-BN, and NO2 + graphene/h-BN, respectively.
When the orbital relaxation energy is the dominant factor, the introduction of the h-BN substrate changes the orbital relaxation, enhancing the sensitivity of graphene to NO2, such as increasing the adsorption energies and the reduction of the shortest distances between the graphene/h-BN and the adsorbed gas molecules.
We then investigated the adsorption mechanism of pristine graphene and graphene/h-BN upon the adsorption of toxic gases, including CO2, CO, NO, and NO2.
The NO2 molecule adopted a configuration in which two oxygen atoms pointed downward towards the graphene surface, and atoms O, N, and O formed an inverted V-shaped pattern.
The graphene/ h-BN heterostructure exhibited a greater selectivity for NO2 gas and inertness toward COx gases.
The optimized geometric structures of the adsorp- tion systems.We performed calculations with the use of a computational DFT-based nanoscope to determine the most preferred geometric configurations of CO, CO2, NO, and NO2 molecules absorbed on graphene/h-BN as well as on pristine graphene.
The term "nitrogen dioxide," for the purposes of stack emissions monitoring, shall include nitrogen dioxide (the chemical compound containing one atom of nitrogen and two atoms of oxygen), nitric oxide (the chemical compound containing one atom of nitrogen and one atom of oxygen), and other oxides of nitrogen which may test as nitrogen dioxide and is sometimes referred to as NOx or NO2.
