Graphene gas sensors

In this paper, I present first-principle calculations which are performed by using combination of DFT and NEGF methods to investigate the adsorption of CO2 and NH3 molecules on straight and U-shaped GNRs junctions. The density of state, molecular orbital, adsorption energy, transmission spectrum, and current-voltage characteristics were analyzed.

To successfully fabricate on-chip sensors based on α-Fe2O3, ZFO NFs and their loading with RGO by on-chip electrospinning. To explore the effect of parameters (i.e. solution composition, heat treatment, electrospun time, and RGO concentration) of fabrication process on the NF morphology, structure and H2S gas sensing properties.
