To this aim, carbon nanoparticles with distinctive properties and nanostructures had been developed in ethylene/air laminar premixed flames at various residence times. Particles were collected on mica substrates by indicates of a thermophoretic sampling program then analyzed by AFM. An experimental procedure based on the combination amongst semicontact AFM topography imaging, make contact with AFM topography imaging and AFM force spectroscopy has been implemented. More specifically, a preliminary topological characterization with the samples was first performed operating AFM in semicontact mode and then tipsample interaction forces were measured in get in touch with spectroscopy mode. Finally, semicontact mode was made use of to image the indented surface of the samples and to retrieve the projected area of indents. The hardness of investigated samples was obtained from the force istance curves measured in spectroscopy mode and the images of intends acquired in semicontact mode. Moreover, the Young’s modulus was measured by fitting the linear element with the retraction force curves working with a model according to the Hertz theory. The intense force sensitivity of this approach (down to nNewton) as well as the small size of the probe tends to make it incredibly appropriate for performing.
