Keywords: 1D nanostructures; conductometric devices; electrospinning; gas sensors; optical sensors; resonators; Review 1 Introduction The monitoring and control of air pollutants, toxic gases and explosives has become increasingly important for human wellness

• due to gas adsorption or desorption, the resistance of the sensing layer changes. To date, many types of nanomaterials in different structures have been synthesized and employed in conductometric devices for gas sensing applications [12][34][92]. 4.1.1 Pure semiconducting metal oxides: Several types

• . Samples were finally mounted on TO39 packages using electro-soldered gold wires. A flow-meter technique was used to evaluate the performance of fabricated conductometric devices for the detection of two common air contaminants, namely carbon monoxide (CO) and nitrogen dioxide (NO2). Samples were mounted

• of conductometric devices in which multilayer graphene films have been directly synthesized on insulating SiO2 substrates by means of a transfer-free CVD method mediated by Mo. The pre-patterning of the Mo layer allows the graphene to be shaped in the desired form by means of standard lithography
