A Study about Surface Chemical-Physics Mechanisms Occurring for Interacting Metal Nanostructures / gas NO2

di Stasio S., Dal Santo V., National Research Council of Italy (CNR), IT

Zinc nanostructures synthesized with different morphologies from the same evaporation/condensation technique are studied with concern to surface reactivity to NO2 by Diffuse Reflectance Infrared Fourier Transformed Spectroscopy (DRIFTS). Synthesis of nanopowders is obtained, according to [...]

Effect of thermal treatments on the structure of photoactive titanium oxides

Diamanti M.V., Codeluppi S., Cordioli A., Pedeferri MP., Politecnico di Milano, IT

Nanocrystalline TiO2 is one of the most important and used photocatalysts because of the excellent efficiencies of conversion of chemical species, and its chemical stability. Its photocatalytic properties are activated only by UV light; nevertheless, [...]

Interaction between alternating current and cathodic protection over nano sized/structured surface metals

Lazzari L., Ormellese M., Bueno V., Politecnico di Milano, IT

Serious cases of corrosion in metal structures under both alternating current (AC) and cathodic protection (CP) have been reported. The objective of this research is the proposal of a mechanism by which AC affects the [...]

MWCNTS Production by Means of Pyrolysis of Polyethylene-Terephtalate in a Bubbling Fluidized Bed

Mastellone M.L., Arena U., Second University of Naples, IT

A bubbling fluidized bed reactor having 102mmID and realised in AISI 316L stainless steel has been used as pyrolyser under different operating conditions. The reactor has been operated at fixed fluidising velocity (U=0.16m/s) and at [...]

Multiwalled carbon nanotube films as temperature nano-sensors

Di Bartolomeo A., Giubileo F., Sarno M., Altavilla C., Sannino D., Iemmo L., Mancusi D., Bobba F., Cucolo A.M., Ciambelli P., University of Salerno, IT

The understanding of the temperature dependence of the electric resistance of carbon nanotubes (CNTs) is a very important feature for the potential utilization as sensing element in temperature nano-sensors. The sensitivity and the time response [...]

Resistance measurements and weak localization in long SWNTs

Gabrielli P.G., Gabrielli S., Gabrielli P.G., Gabrielli S., Lisi N., ENEA, IT

In the theory of the 1-d electron systems, called Tomonaga-Luttinger-liquid (LL), the correlated electron state is characterized by a parameter g that measures the strength of the interaction between the electrons (g=1 for non-interacting electron [...]

High performance iPP based nanocomposite for food packaging application

Avella M., Errico M.E., Gentile G., INSTITUTE OF POLYMER CHEMISTRY AND TECHNOLOGY - CNR, IT

High performance iPP based nanocomposites filled with innovative calcium carbonate nanoparticles were prepared by melt mixing. Peculiarities of the nanoparticles were the high specific surface area, the elongated shape (aragonite), and the surface modifiers (polypropylene-maleic [...]

Gas Sensor Arrays by Supersonic Cluster Beam Deposition

Barborini E., Leccardi M., Bertolini G., Rorato O., Franchi M., Bandiera D., Gatelli M., Wegner K., Raso A., Garibbo A., Ducati C., Piseri P., Milani P., Tethis S.r.l., IT

Supersonic cluster beam deposition was employed to produce nanostructured thin films of transition metal oxides to be used as gas sensors. The cluster beam was generated by a pulsed microplasma cluster source equipped with aerodynamic [...]

CNT Composites for Aerospace Applications

Bellucci S., Balasubramanian C., Borin P., Micciulla F., Rinaldi G., INFN-Laboratori Nazionali di Frascati, IT

Carbon nanotubes are being widely studied for various applications ranging from medical to electronics and also optical devices. They are also being studied for the suitability and applications in aerospace and aeronautical field. A useful [...]
