Patent number: 9376538Abstract: A nanoporous polymeric membrane is obtained by bombing a polymer film by means of high energy focused heavy ion beams and subsequently performing chemical etching to remove the portions of the polymer film in the zones degraded by the ion bombing, in such a manner to obtain pores passing through the polymer film. The heavy ion bombing is performed after interposing between the source of ions and the polymer film, adjacent to the film, an amplitude mask having an ordered arrangement of nanopores and having sufficient thickness to prevent the passage of the heavy ions that are not directed through the pores of said amplitude mask, in such a manner to obtain in the polymer fill an ordered arrangement of nanopores having an aspect-ratio at least exceeding 10 and preferably exceeding 100.Type: GrantFiled: December 23, 2010Date of Patent: June 28, 2016Assignee: C.R.F.

Patent number: 7061129Abstract: The generator comprises at least one source of pressurized gas and a closed hydraulic circuit containing a solution comprising an electrically conducting vehicle liquid in which a charge of micro- or nanoparticles of a metal material is dispersed. The circuit has at least one inlet port connected to the source so that, when in operation, it receives a flow of pressurized gas capable of causing circulation of the solution within the circuit in a predetermined direction, forming a two-phase gas-liquid mixture with it, a restriction in cross section, downstream from the inlet port calibrated in such a way as to cause an increase in velocity and condensation of the two-phase mixture, and at least one outlet port, located downstream from the restriction through which the gas mixed with the solution can be released and discharged from the circuit.Type: GrantFiled: December 20, 2004Date of Patent: June 13, 2006Assignee: C.R.F.

Publication number: 20050160737Abstract: The combustor comprises a stationary structure and at least one tubular rotor supported rotatably about an axis by the structure by means of contactless suspension devices there being formed within this rotor at least one combustion chamber having at least one orientated lateral outflow aperture for the ejection of the combustion gases. The rotor has a narrow circumferential slot through which there extend at least one controlled stationary injector of fuel and combustion agent and an associated igniter which is also stationary. A control unit operates the injector and the igniter according to predetermined procedures, in such a way as to generate a detonation wave which is propagated in the chamber, and to cause the rotor to rotate as a result of the thrust due to the combustion gases emitted through the lateral outflow aperture.Type: ApplicationFiled: December 23, 2004Publication date: July 28, 2005Inventors: Pietro Perlo, Gianfranco Innocenti, Piermario Repetto, Mauro Sgroi, Gianluca Bollito, Bartolo Pairetti, Rossella Monferino, Roberto Finizio, Cosimo Carvignese

Publication number: 20050155639Abstract: The device includes a combustor comprising an inlet chamber or region intended to receive a flow of fuel and a combustion supporter at high pressure, an outlet chamber or region or combustion product exhaust at relatively lower pressure, and at least one separation element of nano-porous or micro-porous semi-conductor material which separates the inlet chamber or region from the outlet chamber or region. The separation element has a plurality of nano-pores or micro-pores passing therethrough which define communication passages between the inlet clad chamber or region and the outlet chamber or region. The surface of these pores is at least partly clad in a layer of an electrically conductive or semi-conductive material which, relative to the semi-conductor material of the separation element forms an essentially extended junction, in particular a p-n junction or a Schottky junction or a hetero junction.Type: ApplicationFiled: November 4, 2004Publication date: July 21, 2005Inventors: Pietro Perlo, Anatolii Zvezdin, Gianfranco Innocenti, Piermario Repetto, Mauro Brignone, Marco Pizzi, Gianluca Bollito, Mauro Sgroi, Roberto Finizio, Cosimo Carvignese
