Nanolab System for Nanoelectronics and Sensors

Dimonte A., Demarchi D., Civera P., Piccinini G., Politecnico di Torino, IT

This project idea is the implementation of a complete and general system for the realization of nanodevices based on nanogaps (small gaps in a gold wire) exploited with a feedback controlled circuit. The system, built [...]

A MEMS-Based Wide-Band Multi-State Power Attenuator for Radio Frequency and Microwave Applications

Iannacci J., Faes A., Mastri F., Masotti D., Rizzoli V., Fondazione Bruno Kessler - FBK, IT

We propose the implementation of a widely reconfigurable broad-band power attenuator for Radio Frequency (RF) and Microwave signals, entirely based on the RF-MEMS surface micromachining technology available at FBK in Italy. The network realizes a [...]

Critical currents in graphene ribbon Josephson junctions

Gabrielli P.G., ENEA, IT

Most of the remarkable transport properties of graphene have to do with its particular band structure at low energies: the undoped system has a finite number of Fermi points, placed at the corner of the [...]

Directed assembly of magnetic nanoparticles in polymers: the formation of anisotropic plastic films containing aligned nanowires

Fragouli D., Buonsanti R., Villafiorita Monteleone F., Bertoni G., Sangregorio C., Torre B., Cingolani R., Athanassiou A., Italian Institute of Technology, IT

We present a study of the dynamical formation of spatially localized arrays of 1-D aligned magnetic nanowires in plastic films. We demonstrate a straightforward technique, easily reproducible, where by specifically varying experimental conditions we can [...]

Synthesis of polynobornene on catalyst functionalized-MWCNTs with a “grafting from” approach: The influence of the catalyst-MWCNT spacing

Longo P., Costabile C., Grisi F., Latorraca N., Ciambelli P., Sarno M., Leone C., Sannino D., University of Salerno, IT

The synthesis of “homogeneuos” polymeric composites containing multi-walled carbon nanotubes (MWNT), that could effectively combine the properties of carbon nanotubes with the solubility and processability of polymers, has emerged as one of the most important [...]

An experimental and theoretical study of the inhibition mechanism of organic substances in concrete

Diamanti M.V., Ormellese M., Perez-Rosales E.A., Pedeferri MP., Raffaini G., Ganazzoli F., Politecnico di Milano, IT

Corrosion inhibitors are one of the preventative techniques used to prevent chloride-induced corrosion in reinforced concrete structures. Several commercial inhibitors are available on the market, but their efficiency as well as their inhibitive mechanism are [...]

Rhodamine B degradation efficiency of differently annealed titanium dioxide nanotubes

Diamanti M.V., Stercal F., Pedeferri MP., Politecnico di Milano, IT

This paper presents an investigation over the photoefficiency of nanotubular titanium dioxide films in the degradation of organic pollutants: rhodamine B was chosen as model reactant. The effects of thermal treatments in several atmospheres on [...]

Au, Ag and Au-Ag nanoparticles: microwave-assisted synthesis in water and applications in ceramic and catalysis

Blosi M., Albonetti S., Gatti F., Dondi M., Migliori A., Ortolani L., Morandi V., Baldi G., Istec-CNR, IT

The research was focused on the synthesis of Au, Ag and Au-Ag core-shell sols, prepared by a patented microwave-assisted green synthesis. The method provides colloidal mono and bimetallic nanoparticles throughout the reduction of precursor’s salts [...]

Synthesis and Characterization of Single Wall Carbon Nanohorns Produced by Direct Vaporization of Graphite

Pagura C., Schiavon M., Barison S., Battiston S., Consiglio Nazionale delle Ricerche, IT

A new patented process for massive production of single wall carbon nanohorn (SWCNH) is presented. Without any catalyst, the prototipe plant is able to produce 100 g/h of high purity carbon nanohorns. The direct vaporization [...]

Key Success Factors in supporting Clean Tech start-ups: a general framework and an Italian experience

Salerno M., Lambkin A., Minola T., Politecnico di Milano, IT

The present seminal work is devoted to the generation of a framework useful to create the conditions for the incubation of Clean Tech startups, especially for research-based companies coming from the universities. In this direction [...]
